Significant Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of Toll Brothers, Inc. (the “Company,” “we,” “us,” or “our”), a Delaware corporation, and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Investments in 50% or less owned partnerships and affiliates are accounted for using the equity method unless it is determined that we have effective control of the entity, in which case we would consolidate the entity. References herein to fiscal year refer to our fiscal years ended or ending October 31. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents Liquid investments or investments with original maturities of three months or less are classified as cash equivalents. Inventory Inventory is stated at cost unless an impairment exists, in which case it is written down to fair value in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360, “Property, Plant, and Equipment” (“ASC 360”). In addition to direct land acquisition costs, land development costs, and home construction costs, costs also include interest, real estate taxes, and direct overhead related to development and construction, which are capitalized to inventory during the period beginning with the commencement of development and ending with the completion of construction. For those communities that have been temporarily closed, no additional capitalized interest is allocated to a community’s inventory until it reopens. While the community remains closed, carrying costs such as real estate taxes are expensed as incurred. We capitalize certain interest costs to qualified inventory during the development and construction period of our communities in accordance with ASC 835-20, “Capitalization of Interest” (“ASC 835-20”). Capitalized interest is charged to cost of revenues when the related inventory is delivered. Interest incurred on home building indebtedness in excess of qualified inventory, as defined in ASC 835-20, is charged to the Consolidated Statements of Operations and Comprehensive Income in the period incurred. Once a parcel of land has been approved for development and we open one of our typical communities, it may take four or more years to fully develop, sell, and deliver all the homes in such community. Longer or shorter time periods are possible depending on the number of home sites in a community and the sales and delivery pace of the homes in a community. Our master planned communities, consisting of several smaller communities, may take up to 10 years or more to complete. Because our inventory is considered a long-lived asset under GAAP, we are required, under ASC 360, to regularly review the carrying value of each community and write down the value of those communities for which we believe the values are not recoverable. Operating Communities : When the profitability of an operating community deteriorates, the sales pace declines significantly, or some other factor indicates a possible impairment in the recoverability of the asset, the asset is reviewed for impairment by comparing the estimated future undiscounted cash flow for the community to its carrying value. If the estimated future undiscounted cash flow is less than the community’s carrying value, the carrying value is written down to its estimated fair value. Estimated fair value is primarily determined by discounting the estimated future cash flow of each community. The impairment is charged to cost of revenues in the period in which the impairment is determined. In estimating the future undiscounted cash flow of a community, we use various estimates such as (i) the expected sales pace in a community, based upon general economic conditions that will have a short-term or long-term impact on the market in which the community is located and on competition within the market, including the number of home sites available and pricing and incentives being offered in other communities owned by us or by other builders; (ii) the expected sales prices and sales incentives to be offered in a community; (iii) costs expended to date and expected to be incurred in the future, including, but not limited to, land and land development, home construction, interest, and overhead costs; (iv) alternative product offerings that may be offered in a community that will have an impact on sales pace, sales price, building cost, or the number of homes that can be built on a particular site; and (v) alternative uses for the property such as the possibility of a sale of the entire community to another builder or the sale of individual home sites. Future Communities : We evaluate all land held for future communities or future sections of operating communities, whether owned or under contract, to determine whether or not we expect to proceed with the development of the land as originally contemplated. This evaluation encompasses the same types of estimates used for operating communities described above, as well as an evaluation of the regulatory environment applicable to the land and the estimated probability of obtaining the necessary approvals, the estimated time and cost it will take to obtain the approvals, and the possible concessions that may be required to be given in order to obtain them. Concessions may include cash payments to fund improvements to public places such as parks and streets, dedication of a portion of the property for use by the public or as open space, or a reduction in the density or size of the homes to be built. Based upon this review, we decide (i) as to land under contract to be purchased, whether the contract will likely be terminated or renegotiated, and (ii) as to land owned, whether the land will likely be developed as contemplated or in an alternative manner, or should be sold. We then further determine whether costs that have been capitalized to the community are recoverable or should be written off. The write-off is charged to cost of revenues in the period in which the need for the write-off is determined. The estimates used in the determination of the estimated cash flows and fair value of both current and future communities are based on factors known to us at the time such estimates are made and our expectations of future operations and economic conditions. Should the estimates or expectations used in determining estimated fair value deteriorate in the future, we may be required to recognize additional impairment charges and write-offs related to current and future communities and such amounts could be material. Variable Interest Entities We are required to consolidate variable interest entities (“VIEs”) in which we have a controlling financial interest in accordance with ASC 810, “Consolidation” (“ASC 810”). A controlling financial interest will have both of the following characteristics: (i) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. Our variable interest in VIEs may be in the form of equity ownership, contracts to purchase assets, management services and development agreements between us and a VIE, loans provided by us to a VIE or other member, and/or guarantees provided by members to banks and other parties. We have a significant number of land purchase contracts and investments in unconsolidated entities which we evaluate in accordance with ASC 810. We analyze our land purchase contracts and the unconsolidated entities in which we have an investment to determine whether the land sellers and unconsolidated entities are VIEs and, if so, whether we are the primary beneficiary. We examine specific criteria and use our judgment when determining if we are the primary beneficiary of a VIE. Factors considered in determining whether we are the primary beneficiary include risk and reward sharing, experience and financial condition of other member(s), voting rights, involvement in day-to-day capital and operating decisions, representation on a VIE’s executive committee, existence of unilateral kick-out rights or voting rights, level of economic disproportionality between us and the other member(s), and contracts to purchase assets from VIEs. The determination whether an entity is a VIE and, if so, whether we are the primary beneficiary may require significant judgment. Property, Construction, and Office Equipment Property, construction, and office equipment are recorded at cost and are stated net of accumulated depreciation of $145.0 million and $126.1 million at October 31, 2018 and 2017 , respectively. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. In fiscal 2018 , 2017 , and 2016 , we recognized $21.0 million , $18.7 million , and $15.5 million of depreciation expense, respectively. Mortgage Loans Held for Sale Residential mortgage loans held for sale are measured at fair value in accordance with the provisions of ASC 825, “Financial Instruments” (“ASC 825”). We believe the use of ASC 825 improves consistency of mortgage loan valuations between the date the borrower locks in the interest rate on the pending mortgage loan and the date of the mortgage loan sale. At the end of the reporting period, we determine the fair value of our mortgage loans held for sale and the forward loan commitments we have entered into as a hedge against the interest rate risk of our mortgage loans using the market approach to determine fair value. The evaluation is based on the current market pricing of mortgage loans with similar terms and values as of the reporting date, and such pricing is applied to the mortgage loan portfolio. We recognize the difference between the fair value and the unpaid principal balance of mortgage loans held for sale as a gain or loss. In addition, we recognize the fair value of our forward loan commitments as a gain or loss. Interest income on mortgage loans held for sale is calculated based upon the stated interest rate of each loan. In addition, the recognition of net origination costs and fees associated with residential mortgage loans originated are expensed as incurred. These gains and losses, interest income, and origination costs and fees are recognized in “Other income - net” in the Consolidated Statements of Operations and Comprehensive Income. Investments in Unconsolidated Entities In accordance with ASC 323, “Investments—Equity Method and Joint Ventures,” we review each of our investments on a quarterly basis for indicators of impairment. A series of operating losses of an investee, the inability to recover our invested capital, or other factors may indicate that a loss in value of our investment in the unconsolidated entity has occurred. If a loss exists, we further review the investment to determine if the loss is other than temporary, in which case we write down the investment to its fair value. The evaluation of our investment in unconsolidated entities entails a detailed cash flow analysis using many estimates, including, but not limited to, expected sales pace, expected sales prices, expected incentives, costs incurred and anticipated, sufficiency of financing and capital, competition, market conditions, and anticipated cash receipts, in order to determine projected future distributions from the unconsolidated entity. In addition, for rental properties, we review rental trends, expected future expenses, and expected cash flows to determine estimated fair values of the properties. Our unconsolidated entities that develop land or develop for-sale homes and condominiums evaluate their inventory in a similar manner as we do. See “Inventory” above for more detailed disclosure on our evaluation of inventory. For our unconsolidated entities that own, develop, and manage for-rent residential apartments, we review rental trends, expected future expenses, and expected future cash flows to determine estimated fair values of the properties. If a valuation adjustment is recorded by an unconsolidated entity related to its assets, our proportionate share is reflected in income from unconsolidated entities with a corresponding decrease to our investment in unconsolidated entities. We are a party to several joint ventures with unrelated parties to develop and sell land that is owned by the joint ventures. We recognize our proportionate share of the earnings from the sale of home sites to other builders, including our joint venture partners. We do not recognize earnings from the home sites we purchase from these ventures at the time of purchase; instead, our cost basis in those home sites is reduced by our share of the earnings realized by the joint venture from sales of those home sites to us. We are also a party to several other joint ventures. We recognize our proportionate share of the earnings and losses of our unconsolidated entities. Fair Value Disclosures We use ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), to measure the fair value of certain assets and liabilities. ASC 820 provides a framework for measuring fair value in accordance with GAAP, establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value, and requires certain disclosures about fair value measurements. The fair value hierarchy is summarized below: Level 1: Fair value determined based on quoted prices in active markets for identical assets or liabilities. Level 2: Fair value determined using significant observable inputs, generally either quoted prices in active markets for similar assets or liabilities or quoted prices in markets that are not active. Level 3: Fair value determined using significant unobservable inputs, such as pricing models, discounted cash flows, or similar techniques. Treasury Stock Treasury stock is recorded at cost. Issuance of treasury stock is accounted for on a first-in, first-out basis. Differences between the cost of treasury stock and the re-issuance proceeds are charged to additional paid-in capital. Revenue and Cost Recognition Revenues and cost of revenues from home sales are recorded at the time each home is delivered and title and possession are transferred to the buyer. For our standard attached and detached homes, land, land development, and related costs, both incurred and estimated to be incurred in the future, are amortized to the cost of homes closed based upon the total number of homes to be constructed in each community. Any changes resulting from a change in the estimated number of homes to be constructed or in the estimated land, land development, and related costs subsequent to the commencement of delivery of homes are allocated to the remaining undelivered homes in the community. Home construction and related costs are charged to the cost of homes closed under the specific identification method. The estimated land, common area development, and related costs of master planned communities, including the cost of golf courses, net of their estimated residual value, are allocated to individual communities within a master planned community on a relative sales value basis. Any changes resulting from a change in the estimated number of homes to be constructed or in the estimated costs are allocated to the remaining home sites in each of the communities of the master planned community. For high-rise/mid-rise projects, land, land development, construction, and related costs, both incurred and estimated to be incurred in the future, are generally amortized to the cost of units closed based upon an estimated relative sales value of the units closed to the total estimated sales value. Any changes resulting from a change in the estimated total costs or revenues of the project are allocated to the remaining units to be delivered. Forfeited Customer Deposits: Forfeited customer deposits are recognized in “Other income – net” in our Consolidated Statements of Operations and Comprehensive Income in the period in which we determine that the customer will not complete the purchase of the home and we have the right to retain the deposit. Sales Incentives: In order to promote sales of our homes, we grant our home buyers sales incentives from time to time. These incentives will vary by type of incentive and by amount on a community-by-community and home-by-home basis. Incentives that impact the value of the home or the sales price paid, such as special or additional options, are generally reflected as a reduction in sales revenues. Incentives that we pay to an outside party, such as paying some or all of a home buyer’s closing costs, are recorded as an additional cost of revenues. Incentives are recognized at the time the home is delivered to the home buyer and we receive the sales proceeds. Advertising Costs We expense advertising costs as incurred. Advertising costs were $28.5 million , $26.1 million , and $23.1 million for the years ended October 31, 2018 , 2017 , and 2016 , respectively. Warranty and Self-Insurance Warranty: We provide all of our home buyers with a limited warranty as to workmanship and mechanical equipment. We also provide many of our home buyers with a limited 10 -year warranty as to structural integrity. We accrue for expected warranty costs at the time each home is closed and title and possession are transferred to the home buyer. Warranty costs are accrued based upon historical experience. Adjustments to our warranty liabilities related to homes delivered in prior periods are recorded in the period in which a change in our estimate occurs. Over the past several years, we have had a significant number of warranty claims related primarily to homes built in Pennsylvania and Delaware. See Note 7 – “Accrued Expenses” for additional information regarding these warranty charges. Self-Insurance: We maintain, and require the majority of our subcontractors to maintain, general liability insurance (including construction defect and bodily injury coverage) and workers’ compensation insurance. These insurance policies protect us against a portion of our risk of loss from claims related to our home building activities, subject to certain self-insured retentions, deductibles and other coverage limits (“self-insured liability”). We also provide general liability insurance for our subcontractors in Arizona, California, Colorado, Nevada, Washington, and certain areas of Texas, where eligible subcontractors are enrolled as insureds under our general liability insurance policies in each community in which they perform work. For those enrolled subcontractors, we absorb their general liability associated with the work performed on our homes within the applicable community as part of our overall general liability insurance and our self-insured liability. We record expenses and liabilities based on the estimated costs required to cover our self-insured liability and the estimated costs of potential claims and claim adjustment expenses that are above our coverage limits or that are not covered by our insurance policies. These estimated costs are based on an analysis of our historical claims and industry data, and include an estimate of claims incurred but not yet reported (“IBNR”). We engage a third-party actuary that uses our historical claim and expense data, input from our internal legal and risk management groups, as well as industry data, to estimate our liabilities related to unpaid claims, IBNR associated with the risks that we are assuming for our self-insured liability, and other required costs to administer current and expected claims. These estimates are subject to uncertainty due to a variety of factors, the most significant being the long period of time between the delivery of a home to a home buyer and when a structural warranty or construction defect claim may be made, and the ultimate resolution of the claim. Though state regulations vary, construction defect claims may be reported and resolved over a prolonged period of time, which can extend for 10 years or longer. As a result, the majority of the estimated liability relates to IBNR. Adjustments to our liabilities related to homes delivered in prior years are recorded in the period in which a change in our estimate occurs. The projection of losses related to these liabilities requires actuarial assumptions that are subject to variability due to uncertainties regarding construction defect claims relative to our markets and the types of product we build, insurance industry practices, and legal or regulatory actions and/or interpretations, among other factors. Key assumptions used in these estimates include claim frequencies, severities, and settlement patterns, which can occur over an extended period of time. In addition, changes in the frequency and severity of reported claims and the estimates to settle claims can impact the trends and assumptions used in the actuarial analysis, which could be material to our consolidated financial statements. Due to the degree of judgment required, and the potential for variability in these underlying assumptions, our actual future costs could differ from those estimated, and the difference could be material to our consolidated financial statements. Stock-Based Compensation We account for our stock-based compensation in accordance with ASC 718, “Compensation – Stock Compensation” (“ASC 718”). We use a lattice model for the valuation for our stock option grants. The option pricing models used are designed to estimate the value of options that, unlike employee stock options and restricted stock units, can be traded at any time and are transferable. In addition to restrictions on trading, employee stock options and restricted stock units may include other restrictions such as vesting periods. Further, such models require the input of highly subjective assumptions, including the expected volatility of the stock price. Stock-based compensation expense is generally included in “Selling, general and administrative” expense in our Consolidated Statements of Operations and Comprehensive Income. Legal Expenses Transactional legal expenses for land acquisition and entitlement, and financing are capitalized and expensed over their appropriate life. We expense legal fees related to litigation, warranty and insurance claims when incurred. Income Taxes We account for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recorded based on temporary differences between the amounts reported for financial reporting purposes and the amounts reported for income tax purposes. In accordance with the provisions of ASC 740, we assess the realizability of our deferred tax assets. A valuation allowance must be established when, based upon available evidence, it is more likely than not that all or a portion of the deferred tax assets will not be realized. See “Income Taxes – Valuation Allowance” below. Federal and state income taxes are calculated on reported pre-tax earnings based on current tax law and also include, in the applicable period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized for financial reporting purposes in different periods than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions. We establish reserves for income taxes when, despite the belief that our tax positions are fully supportable, we believe that our positions may be challenged and disallowed by various tax authorities. The consolidated tax provisions and related accruals include the impact of such reasonably estimable disallowances as deemed appropriate. To the extent that the probable tax outcome of these matters changes, such changes in estimates will impact the income tax provision in the period in which such determination is made. ASC 740 clarifies the accounting for uncertainty in income taxes recognized and prescribes a recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. ASC 740 requires a company to recognize the financial statement effect of a tax position when it is “more-likely-than-not” (defined as a substantiated likelihood of more than 50% ), based on the technical merits of the position, that the position will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to be recognized in the financial statements based upon the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. Our inability to determine that a tax position meets the more-likely-than-not recognition threshold does not mean that the Internal Revenue Service (“IRS”) or any other taxing authority will disagree with the position that we have taken. If a tax position does not meet the more-likely-than-not recognition threshold, despite our belief that our filing position is supportable, the benefit of that tax position is not recognized in the Consolidated Statements of Operations and Comprehensive Income and we are required to accrue potential interest and penalties until the uncertainty is resolved. Potential interest and penalties are recognized as a component of the provision for income taxes. Differences between amounts taken in a tax return and amounts recognized in the financial statements are considered unrecognized tax benefits. We believe that we have a reasonable basis for each of our filing positions and intend to defend those positions if challenged by the IRS or other taxing jurisdiction. If the IRS or other taxing authorities do not disagree with our position, and after the statute of limitations expires, we will recognize the unrecognized tax benefit in the period that the uncertainty of the tax position is eliminated. Income Taxes — Valuation Allowance We assess the need for valuation allowances for deferred tax assets in each period based on whether it is more-likely-than-not that some portion of the deferred tax asset would not be realized. If, based on the available evidence, it is more-likely-than-not that such asset will not be realized, a valuation allowance is established against a deferred tax asset. The realization of a deferred tax asset ultimately depends on the existence of sufficient taxable income in either the carryback or carryforward periods under tax law. This assessment considers, among other matters, the nature, consistency, and magnitude of current and cumulative income and losses; forecasts of future profitability; the duration of statutory carryback or carryforward periods; our experience with operating loss and tax credit carryforwards being used before expiration; tax planning alternatives: and outlooks for the U.S. housing industry and broader economy. Changes in existing tax laws or rates could also affect our actual tax results. Due to uncertainties in the estimation process, particularly with respect to changes in facts and circumstances in future reporting periods, actual results could differ from the estimates used in our assessment that could have a material impact on our consolidated results of operations or financial position. Segment Reporting We operate in two segments: traditional home building and urban infill. We build and sell homes for detached and attached homes in luxury residential communities located in affluent suburban markets and cater to move-up, empty-nester, active-adult, and second-home buyers in the United States (“Traditional Home Building”). We also build and sell homes in urban infill markets through Toll Brothers City Living ® (“City Living”). We have determined that our Traditional Home Building operations operate in five geographic segments: North, Mid-Atlantic, South, West, and California. The states comprising each geographic segment are as follows: North: Connecticut, Illinois, Massachusetts, Michigan, New Jersey, and New York Mid-Atlantic: Delaware, Maryland, Pennsylvania, and Virginia South: Florida, North Carolina, and Texas West: Arizona, Colorado, Idaho, Nevada, and Washington California: California In fiscal 2018, we acquired land and commenced development activities in the Salt Lake City, Utah and Portland, Oregon markets. We expect to open communities in these markets in fiscal 2019. In fiscal 2018, we discontinued the sale of homes in Minnesota. Our operations in Minnesota were immaterial to the North geographic segment. Related Party Transactions See Note 4, “Investments in Unconsolidated Entities - Rental Property Joint Ventures” for information regarding Toll Brothers Realty Trust. Recent Accounting Pronouncements In February 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”). ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act enacted on December 22, 2017 and also requires entities to disclose their accounting policy for releasing income tax effects from accumulated other comprehensive income. We elected to adopt ASU 2018-02 in the first quarter of fiscal 2018, and the adoption did not have a material effect on our consolidated financial statements and disclosures. In March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”). ASU 2017-07 requires an employer to report the service cost component of pension and other post-retirement benefit costs in the same line item as other compensation costs arising from services rendered by the pertinent employees while the other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations; such other costs are included in other income-net in our Consolidated Statements of Operations and Comprehensive Income. We adopted ASU 2017-07 on November 1, 2017, and the adoption did not have a material effect on our consolidated financial statements and disclosures. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes and forfeitures, statutory tax withholding requirements and classification on the statement of cash flows. We adopted ASU 2016-09 on November 1, 2017. Excess tax benefits or deficiencies for stock-based compensation are now reflected in our Consolidated Statements of Operations and Comprehensive Income as a component of income tax expense, whereas previously they were recognized in equity. We have also elected to account for forfeitures as they occur, rather than estimate expected forfeitures. As a result of adopting ASU 2016-09, the impact of recognizing excess tax benefits and deficiencies in our Consolidated Statements of Operations and Comprehensive Income resulted in a $4.2 million reduction in our income tax expense in our fiscal year ending October 31, 2018 . The remaining aspects of adopting ASU 2016-09 did not have a material impact on our financial statements and disclosures. In February 2017, the FASB issued ASU No. 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Su

Inventory Disclosure [Abstract]
Inventory	Inventory Inventory at October 31, 2018 and 2017 consisted of the following (amounts in thousands): 2018 2017 Land controlled for future communities $ 139,985 $ 87,158 Land owned for future communities 916,616 1,142,870 Operating communities 6,541,618 6,051,425 $ 7,598,219 $ 7,281,453 Operating communities include communities offering homes for sale, communities that have sold all available home sites but have not completed delivery of the homes, communities that were previously offering homes for sale but are temporarily closed due to business conditions or non-availability of improved home sites and that are expected to reopen within 12 months of the end of the fiscal year being reported on, and communities preparing to open for sale. The carrying value attributable to operating communities includes the cost of homes under construction, land and land development costs, the carrying cost of home sites in current and future phases of these communities, and the carrying cost of model homes. Communities that were previously offering homes for sale but are temporarily closed due to business conditions, do not have any remaining backlog, and are not expected to reopen within 12 months of the end of the fiscal period being reported on have been classified as land owned for future communities. Backlog consists of homes under contract but not yet delivered to our home buyers (“backlog”). Information regarding the classification, number, and carrying value of these temporarily closed communities at October 31, 2018 , 2017 , and 2016 , is provided in the table below ($ amounts in thousands): 2018 2017 2016 Land owned for future communities: Number of communities 17 14 18 Carrying value (in thousands) $ 124,426 $ 110,732 $ 123,936 Operating communities: Number of communities 1 6 3 Carrying value (in thousands) $ 2,622 $ 26,749 $ 8,523 We provided for inventory impairment charges and the expensing of costs that we believed not to be recoverable in each of the three fiscal years ended October 31, 2018 , 2017 , and 2016 , as shown in the table below (amounts in thousands): Charge: 2018 2017 2016 Land controlled for future communities $ 2,820 $ 1,949 $ 3,142 Land owned for future communities 2,185 3,050 2,300 Operating communities 30,151 9,795 8,365 $ 35,156 $ 14,794 $ 13,807 See Note 12, “Fair Value Disclosures,” for information regarding the number of operating communities that we tested for potential impairment, the number of operating communities in which we recognized impairment charges, the amount of impairment charges recognized, and the fair value of those communities, net of impairment charges. See Note 15, “Commitments and Contingencies,” for information regarding land purchase commitments. At October 31, 2018 , we evaluated our land purchase contracts, including those to acquire land for apartment developments, to determine whether any of the selling entities were VIEs and, if they were, whether we were the primary beneficiary of any of them. Under these land purchase contracts, we do not possess legal title to the land; our risk is generally limited to deposits paid to the sellers and predevelopment costs incurred; and the creditors of the sellers generally have no recourse against us. At October 31, 2018 , we determined that 110 land purchase contracts, with an aggregate purchase price of $1.88 billion , on which we had made aggregate deposits totaling $120.5 million , were VIEs, but that we were not the primary beneficiary of any VIE related to such land purchase contracts. At October 31, 2017 , we determined that 104 land purchase contracts, with an aggregate purchase price of $1.43 billion , on which we had made aggregate deposits totaling $65.6 million , were VIEs, but that we were not the primary beneficiary of any VIE related to such land purchase contracts. Interest incurred, capitalized, and expensed in each of the three fiscal years ended October 31, 2018 , 2017 , and 2016 , was as follows (amounts in thousands): 2018 2017 2016 Interest capitalized, beginning of year $ 352,049 $ 369,419 $ 373,128 Interest incurred 165,977 175,944 164,001 Interest expensed to cost of revenues (190,734 ) (172,832 ) (160,337 ) Interest expensed to other income (3,760 ) (4,823 ) (1,143 ) Interest reclassified to property, construction, and office equipment (485 ) (1,111 ) Interest capitalized on investments in unconsolidated entities (7,220 ) (8,824 ) (5,818 ) Previously capitalized interest transferred to investments in unconsolidated entities (8,708 ) Previously capitalized interest on investments in unconsolidated entities transferred to inventory 3,052 2,358 699 Interest capitalized, end of year $ 319,364 $ 352,049 $ 369,419 During fiscal 2017, we reclassified $9.0 million of inventory related to two golf courses to property, construction, and office equipment and such amount was net of $3.5 million transferred to accrued liabilities related to deferred golf membership fees. During fiscal 2016, we reclassified $17.1 million of inventory related to two golf course facilities and a parking garage to property, construction, and office equipment and such amount was net of $2.1 million transferred to accrued liabilities related to deferred golf membership fees. The amounts were reclassified due to the completion of construction of the facilities and the substantial completion of the master planned communities of which the golf facilities are a part.

Investments in and Advances to Unconsolidated Entities [Abstract]
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities We have investments in various unconsolidated entities. These entities, which are structured as joint ventures (i) develop land for the joint venture participants and for sale to outside builders (“Land Development Joint Ventures”); (ii) develop for-sale homes (“Home Building Joint Ventures”); (iii) develop luxury for-rent residential apartments, commercial space, and a hotel (“Rental Property Joint Ventures”), which includes our investment in Toll Brothers Realty Trust (the “Trust”); and (iv) invest in distressed loans and real estate and provide financing and land banking to residential builders and developers for the acquisition and development of land and home sites (“Gibraltar Joint Ventures”). In fiscal 2018 , 2017 and 2016 , we recognized income from the unconsolidated entities in which we had an investment of $85.2 million , $116.1 million , and $40.7 million , respectively. The table below provides information as of October 31, 2018 , regarding active joint ventures that we are invested in, by joint venture category ($ amounts in thousands): Land Home Building Rental Property Gibraltar Joint Ventures Total Number of unconsolidated entities 7 4 15 7 33 Investment in unconsolidated entities $ 176,593 $ 65,936 $ 171,216 $ 18,068 $ 431,813 Number of unconsolidated entities with funding commitments by the Company 4 1 2 1 8 Company’s remaining funding commitment to unconsolidated entities $ 19,961 $ 8,300 $ 1,578 $ 9,621 $ 39,460 Certain joint ventures in which we have investments obtained debt financing to finance a portion of their activities.

Land Development Joint Ventures In fiscal 2018 , our Land Development Joint Ventures sold approximately 986 lots and recognized revenues of $351.4 million . We acquired 259 of these lots for $153.2 million . Our share of the joint venture income from the lots we acquired of $1.7 million was deferred by reducing our basis in those lots acquired. The Company recognized charges in connection with two Land Development Joint Ventures of $6.0 million in fiscal 2018 . In fiscal 2017 , our Land Development Joint Ventures sold approximately 1,132 lots and recognized revenues of $288.4 million . We acquired 364 of these lots for $166.5 million . Our share of the income from the lots we acquired of $13.5 million was deferred by reducing our basis in those lots acquired. The Company recognized charges in connection with one Land Development Joint Venture of $2.0 million in fiscal 2017 . Home Building Joint Ventures Our Home Building Joint Ventures are delivering homes in New York City and Jupiter, Florida. In fiscal 2018 and 2017 , our Home Building Joint Ventures delivered 100 homes with a sales value of $148.0 million , and 197 homes with a sales value of $475.3 million , respectively. In fiscal 2017, we entered into two joint ventures with unrelated parties to complete the development of high-rise luxury condominium projects in New York City. Before the formation of these joint ventures, we acquired the properties and incurred approximately $319.8 million of land and land development costs. These joint ventures, in which we have interests ranging from 20% to 25% , purchased the properties from us at our cost, a portion of which was financed by $380.5 million in construction loans obtained by the joint ventures. From these sales and financings, we received proceeds of $263.9 million . In the first quarter of fiscal 2015, we entered into a joint venture with an unrelated party to complete the development of a high-rise luxury condominium project in New York City on property that we owned. We contributed $15.9 million as our initial contribution for a 25% interest in this joint venture. We sold the property to the joint venture for $78.5 million , and we were reimbursed for development and construction costs incurred by us prior to the sale. The gain of $9.3 million that we realized on the sale in fiscal 2015 was deferred and was being recognized in our results of operations as units were delivered to the ultimate home buyer. The joint venture commenced settlement of units in fiscal 2016. We recognized $4.7 million and $1.5 million of previously deferred gains in fiscal 2017 and 2016, respectively. In the fourth quarter of fiscal 2017, we purchased our partner’s 75% interest in this joint venture for $36.8 million . Accordingly, the remaining unrecognized deferred gain of $3.0 million was used to adjust our basis in the inventory acquired from the purchase. Rental Property Joint Ventures As of October 31, 2018 , our Rental Property Joint Ventures owned 15 for-rent apartment projects and a hotel, which are located in the metro Boston to metro Washington, D.C. corridor and in suburban Atlanta, Georgia. At October 31, 2018 , these joint ventures had approximately 1,750 units that were occupied or ready for occupancy, 1,400 units in the lease-up stage, and 2,800 units under development. In addition, we either own or have under contract, approximately 9,450 units, of which 1,350 units are under active development; we intend to develop these units in joint ventures with unrelated parties in the future. In fiscal 2018, we entered into four joint ventures with unrelated parties to develop luxury for-rent residential apartment projects located in suburban Atlanta, Georgia; Belmont, Massachusetts; and Washington, D.C. Prior to the formation of these joint ventures, we acquired the properties and incurred approximately $140.0 million of land and land development costs. Our partners acquired interests in these entities ranging from 50% to 75% for an aggregate amount of $80.3 million . In fiscal 2018, several of these joint ventures entered into construction loan agreements for an aggregate amount of $166.1 million to finance the development of these projects. At October 31, 2018 , the joint ventures had $21.8 million of outstanding borrowings under the construction loan facilities. In addition, in fiscal 2018 we entered into a joint venture with an unrelated party to develop a luxury for-rent residential apartment project in a suburb of Boston, Massachusetts. We contributed cash of $15.9 million for our initial 85% ownership interest in this joint venture. Due to our controlling financial interest, our power to direct the activities that most significantly impact the joint venture’s performance, and our obligation to absorb expected losses or receive benefits from the joint venture, we consolidated this joint venture at October 31, 2018 . The carrying value of the joint venture’s assets totaling $19.7 million are reflected in “Receivables, prepaid expenses, and other assets” in our Consolidated Balance Sheet at October 31, 2018 . Our partner’s 15% interest of $2.8 million in the joint venture is reflected as a component of “Noncontrolling interest” in our Consolidated Balance Sheet as of October 31, 2018 . The joint venture expects to admit an additional investor and secure third-party financing at a later date. In fiscal 2018, three of our Rental Property Joint Ventures sold their assets to unrelated parties for $477.5 million . These joint ventures had owned, developed, and operated multifamily rental properties located in suburban Washington, D.C. and Westborough, Massachusetts, and a student housing community in College Park, Maryland. In connection with these sales, the joint ventures’ aggregate outstanding loan balance of $239.6 million was repaid. From our investment in these joint ventures, we received cash of $79.1 million and recognized gains from these sales of $67.2 million in fiscal 2018, which is included in “Income from unconsolidated entities” in our Consolidated Statement of Operations and Comprehensive Income. In the fourth quarter of fiscal 2017, we entered into a joint venture with an unrelated party to develop a 232 -unit luxury for-rent residential apartment project in Princeton Junction, New Jersey. Prior to the formation of this joint venture, we acquired the property and incurred $13.6 million of land and land development costs. Our partner acquired a 75% interest for $10.2 million . The gain of $3.0 million that we realized on the sale was deferred due to our continuing involvement in the joint venture through our retained ownership interest and guarantees we provided on the joint venture’s debt. In the fourth quarter of fiscal 2017, the joint venture entered into a $41.7 million construction loan agreement with a bank to finance the development of this project. At October 31, 2018 , there were $22.1 million of outstanding borrowings under the construction loan. In the third quarter of fiscal 2017, one of our Rental Property Joint Ventures amended its existing $70.0 million construction loan agreement to finance construction of multifamily residential apartments in northern New Jersey. The terms of the amendment extended the maturity date and revised certain guarantees provided for under the loan, including the repayment guaranty for which our obligation increased from 25% to 100% . At October 31, 2018 , this joint venture had $70.0 million of borrowings outstanding under the facility. In fiscal 2017, we sold one-half of our 50% interest in two of our Rental Property Joint Ventures to an unrelated party. In connection with these sales, we, along with our partners, recapitalized the joint ventures and refinanced the existing $166.3 million in construction loans with 10 -year fixed rate loans totaling $189.0 million . As a result of these transactions, we received cash of $54.9 million and recognized gains of $26.7 million in fiscal 2017, which is included in “Income from unconsolidated entities” in our Consolidated Statements of Operations and Comprehensive Income. At October 31, 2018 , we had a 25% interest in each of these joint ventures. We have an investment in a joint venture in which we have a 50% interest that developed a luxury hotel in conjunction with a high-rise luxury condominium project in New York City being developed by a related Home Building Joint Venture. The hotel commenced operations in February 2017. At October 31, 2018 , we had an investment of $35.0 million in this joint venture. In December 2016, this joint venture entered into an $80.0 million , three -year term loan agreement. The proceeds from the term loan, along with proceeds from the closing of condominium units at the Home Building Joint Venture, were used to repay an existing construction loan. In 1998, we formed the Trust to invest in commercial real estate opportunities. The Trust is effectively owned one-third by us; one-third by current and former members of our senior management; and one-third by an unrelated party. As of October 31, 2018 , our investment in the Trust was zero as cumulative distributions received from the Trust have been in excess of the carrying amount of our net investment. We provide development, finance, and management services to the Trust and recognized fees under the terms of various agreements in the amounts of $2.0 million , $2.0 million , and $1.6 million in fiscal 2018 , 2017 and 2016 , respectively. In fiscal 2018 and 2016, we received distributions of $27.7 million and $2.0 million , respectively, from the Trust, of which the full amount was recognized as income and included in “Income from unconsolidated entities” in our fiscal 2018 and 2016 Consolidated Statements of Operations and Comprehensive Income. No distributions were received from the Trust in fiscal 2017. Subsequent events In December 2018, we entered into a joint venture with an unrelated party to develop a 293 -unit student housing community in Miami, Florida. We contributed cash of $13.2 million for our initial 71% ownership interest in this joint venture. Due to our controlling financial interest, our power to direct the activities that most significantly impact the joint venture’s performance, and our obligation to absorb expected losses or receive benefits from the joint venture, we expect to consolidate this joint venture. The joint venture expects to admit an additional investor and secure third-party financing at a later date. In November 2018, we entered into a joint venture with an unrelated party to develop a 421 -unit for-rent residential apartment project in Harrison, New York. Prior to the formation of this joint venture, we acquired the property and incurred approximately $36.1 million of land and land development costs. Our partner acquired a 75% interest in this entity for approximately $35.0 million , of which $34.6 million was distributed to us. We have a 25% interest in this venture and our initial investment is $12.7 million . As a result of the sale of 75% of our interest to our partner, we expect to recognize a gain of approximately $8.5 million in our first quarter of fiscal 2019. Concurrent with its formation, the joint venture entered into a $101.9 million construction loan agreement to finance the development of this project. We and an affiliate of our partner provided certain guarantees under the construction loan agreement. We estimate that the maximum exposure under these guarantees, if the full amount of the loan commitment was borrowed, would be $101.9 million without taking into account any recoveries from the underlying collateral or any reimbursement from our partner. In November 2018, we entered into a joint venture with an unrelated party to develop a 426 -unit for-rent residential apartment project in Boston, Massachusetts. We contributed cash of $26.5 million for our initial 50% ownership interest in this joint venture. The joint venture expects to admit an additional investor and secure third-party financing at a later date. Gibraltar Joint Ventures We, through our wholly owned subsidiary, Gibraltar Capital and Asset Management, LLC (“Gibraltar”), have entered into five ventures with an institutional investor to provide builders and developers with land banking and venture capital, two of which were formed in fiscal 2018. We have approximately a 25% interest in each of these ventures. These ventures will finance builders’ and developers’ acquisition and development of land and home sites and pursue other complementary investment strategies. We may invest up to $100.0 million in these ventures. As of October 31, 2018 , we had an investment of $12.6 million in these ventures. In addition, in the second quarter of fiscal 2016, we entered into a separate venture with the same institutional investor to purchase, from Gibraltar, certain foreclosed real estate owned and distressed loans for $24.1 million . We have a 24% interest in this venture. In fiscal 2016, we recognized a gain of $1.3 million from the sale of these assets to the venture. At October 31, 2018 , we had a $3.7 million investment in this venture and are committed to invest an additional $9.6 million , if necessary. Guarantees The unconsolidated entities in which we have investments generally finance their activities with a combination of partner equity and debt financing. In some instances, we and our partners have guaranteed debt of certain unconsolidated entities. These guarantees may include any or all of the following: (i) project completion guarantees, including any cost overruns; (ii) repayment guarantees, generally covering a percentage of the outstanding loan; (iii) carry cost guarantees, which cover costs such as interest, real estate taxes, and insurance; (iv) an environmental indemnity provided to the lender that holds the lender harmless from and against losses arising from the discharge of hazardous materials from the property and non-compliance with applicable environmental laws; and (v) indemnification of the lender from “bad boy acts” of the unconsolidated entity. In some instances, the guarantees provided in connection with loans to an unconsolidated entity are joint and several. In these situations, we generally have a reimbursement agreement with our partner that provides that neither party is responsible for more than its proportionate share or agreed upon share of the guarantee; however, if the joint venture partner does not have adequate financial resources to meet its obligations under the reimbursement agreement, we may be liable for more than our proportionate share. We believe that, as of October 31, 2018 , in the event we become legally obligated to perform under a guarantee of an obligation of an unconsolidated entity due to a triggering event, the collateral in such entity should be sufficient to repay a significant portion of the obligation. If it is not, we and our partners would need to contribute additional capital to the venture. At October 31, 2018 , certain unconsolidated entities have loan commitments aggregating $1.34 billion , of which, if the full amount of the debt obligations were borrowed, we estimate $294.7 million to be our maximum exposure related to repayment and carry cost guarantees. At October 31, 2018 , the unconsolidated entities had borrowed an aggregate of $1.06 billion , of which we estimate $254.7 million to be our maximum exposure related to repayment and carry cost guarantees. The terms of these guarantees generally range from 8 months to 48 months . These maximum exposure estimates do not take into account any recoveries from the underlying collateral or any reimbursement from our partners. As of October 31, 2018 , the estimated aggregate fair value of the guarantees provided by us related to debt and other obligations of certain unconsolidated entities was approximately $5.6 million . We have not made payments under any of the guarantees, nor have we been called upon to do so. Variable Interest Entities At October 31, 2018 and 2017 , we determined that eleven and eight , respectively, of our joint ventures were VIEs under the guidance within ASC 810. For ten and eight of these VIEs as of October 31, 2018 and 2017 , respectively, we concluded that we were not the primary beneficiary of these VIEs because the power to direct the activities of such VIEs that most significantly impact their performance was either shared by us and such VIEs’ other partners or such activities were controlled by our partner. For VIEs where the power to direct significant activities is shared, business plans, budgets, and other major decisions are required to be unanimously approved by all members. Management and other fees earned by us are nominal and believed to be at market rates, and there is no significant economic disproportionality between us and other members. The information presented below regarding the investments, commitments, and guarantees in unconsolidated entities deemed to be VIEs is also included in the information provided above. As discussed under “Rental Property Joint Ventures” above, we consolidated one joint venture as of October 31, 2018 . The joint venture was determined to be a VIE due to its current inability to finance its activities without additional subordinated financial support as well as our partner’s inability to participate in the significant decisions of the joint venture in addition to its lack of substantive kick-out rights. We further concluded that we were the primary beneficiary of this VIE due to our controlling financial interest in such venture as we have the power to direct the activities that most significantly impact the joint venture’s performance and the obligation to absorb expected losses or receive benefits from the joint venture. The assets of this VIE can only be used to settle the obligations of the VIE. In addition, in the event additional contributions are required to be funded to the joint venture prior to the admission of an additional investor at a future date, we expect that we would fund 100% of such contributions, including our partner’s pro rata share, which we expect would be funded through an interest-bearing loan. At October 31, 2018 and 2017 , our investments in our unconsolidated entities deemed to be VIEs, which are included in “Investments in unconsolidated entities” in our Consolidated Balance Sheets, totaled $33.8 million and $35.9 million , respectively. At October 31, 2018 , the maximum exposure of loss to our investments in these entities was limited to our investments in the unconsolidated VIEs, except with regard to $70.0 million of loan guarantees and $10.8 million of additional commitments to fund the VIEs. Of our potential exposure for these loan guarantees, $70.0 million is related to repayment and carry cost guarantees, of which $70.0 million was borrowed at October 31, 2018 . At October 31, 2017 , the maximum exposure of loss to our investments in these entities was limited to our investments in the unconsolidated VIEs, except with regard to $70.0 million of loan guarantees and $10.5 million of additional commitments to fund the VIEs. Of our potential exposure for these loan guarantees, $70.0 million is related to repayment and carry cost guarantees, of which $61.3 million was borrowed at October 31, 2017 .

Loans Payable, Senior Notes, and Mortgage Company Warehouse Loan	Loans Payable, Senior Notes, and Mortgage Company Loan Facility Loans Payable At October 31, 2018 and 2017 , loans payable consisted of the following (amounts in thousands): 2018 2017 Senior unsecured term loan $ 500,000 $ 500,000 Loans payable – other 188,115 139,116 Deferred issuance costs (1,314 ) (1,700 ) $ 686,801 $ 637,416 Senior Unsecured Term Loan At October 31, 2018 , we had a $500.0 million , five -year senior unsecured term loan facility (the “Term Loan Facility”) with a syndicate of banks that was scheduled to mature in August 2021 . Under the Term Loan Facility, as amended, we may select interest rates equal to (i) London Interbank Offered Rate (“LIBOR”) plus an applicable margin, (ii) the base rate (as defined in the agreement) plus an applicable margin, or (iii) the federal funds/Euro rate (as defined in the agreement) plus an applicable margin, in each case, based on our leverage ratio. At October 31, 2018 , the interest rate on the Term Loan Facility was 3.70% per annum. We and substantially all of our 100% -owned home building subsidiaries are guarantors under the Term Loan Facility. The Term Loan Facility contains substantially the same financial covenants as the Revolving Credit Facility, as described below. Subsequent event On November 1, 2018 , we entered into an amendment to the Term Loan Facility to, among other things, (i) increase the size of the outstanding term loan to $800.0 million ; (ii) extend the maturity date to November 1, 2023 , with no principal payments being required before the maturity date; (iii) provide an accordion feature under which we may, subject to certain conditions set forth in the agreement, increase the Term Loan Facility up to a maximum aggregate amount of $1.0 billion ; (iv) revise certain provisions to reduce the interest rate applicable on outstanding borrowings; and (v) modify certain provisions relating to existing financial maintenance and negative covenants. Revolving Credit Facility We have a $1.295 billion senior unsecured, five -year revolving credit facility (the “Revolving Credit Facility”) with a syndicate of banks. The commitments under the Revolving Credit Facility are scheduled to expire on May 19, 2021 . Up to 50% of the commitment is available for letters of credit. The Revolving Credit Facility has an accordion feature under which we may, subject to certain conditions set forth in the agreement, increase the Revolving Credit Facility up to a maximum aggregate amount of $2.0 billion . We may select interest rates for the Revolving Credit Facility equal to (i) LIBOR plus an applicable margin or (ii) the lenders’ base rate plus an applicable margin, which in each case is based on our credit rating and leverage ratio. At October 31, 2018 , the interest rate on outstanding borrowings under the Revolving Credit Facility would have been 3.80% per annum. We are obligated to pay an undrawn commitment fee that is based on the average daily unused amount of the Aggregate Credit Commitment and our credit ratings and leverage ratio. Any proceeds from borrowings under the Revolving Credit Facility may be used for general corporate purposes. We and substantially all of our 100% -owned home building subsidiaries are guarantors under the Revolving Credit Facility. Under the terms of the Revolving Credit Facility, at October 31, 2018 , our maximum leverage ratio (as defined in the credit agreement) may not exceed 1.75 to 1.00, and we are required to maintain a minimum tangible net worth (as defined in the credit agreement) of no less than approximately $2.50 billion . Under the terms of the Revolving Credit Facility, at October 31, 2018 , our leverage ratio was approximately 0.54 to 1.00 and our tangible net worth was approximately $4.72 billion . Based upon the the limitations related to our repurchase of common stock in the Revolving Credit Facility, our ability to repurchase our common stock was limited to approximately $2.41 billion as of October 31, 2018 . In addition, under the provisions of the Revolving Credit Facility, our ability to pay cash dividends was limited to approximately $2.22 billion as of October 31, 2018 . At October 31, 2018 , we had no outstanding borrowings under the Revolving Credit Facility and had outstanding letters of credit of approximately $165.4 million . Loans Payable – Other “Loans payable – other” primarily represent purchase money mortgages on properties we acquired that the seller had financed and various revenue bonds that were issued by government entities on our behalf to finance community infrastructure and our manufacturing facilities. Information regarding our loans payable at October 31, 2018 and 2017 , is included in the table below ($ amounts in thousands): 2018 2017 Aggregate loans payable at October 31 $ 188,115 $ 139,116 Weighted-average interest rate 4.68 % 4.11 % Interest rate range 1.15% - 7.87% 1.11% - 7.87% Loans secured by assets Carrying value of loans secured by assets $ 152,281 $ 139,116 Carrying value of assets securing loans $ 467,164 $ 483,910 The contractual maturities of “Loans payable – other” as of October 31, 2018 , ranged from two months to 28 years . Senior Notes At October 31, 2018 and 2017 , senior notes consisted of the following (amounts in thousands): 2018 2017 4.00% Senior Notes due December 31, 2018 $ 350,000 $ 350,000 6.75% Senior Notes due November 1, 2019 250,000 250,000 5.875% Senior Notes due February 15, 2022 419,876 419,876 4.375% Senior Notes due April 15, 2023 400,000 400,000 5.625% Senior Notes due January 15, 2024 250,000 250,000 4.875% Senior Notes due November 15, 2025 350,000 350,000 4.875% Senior Notes due March 15, 2027 450,000 450,000 4.35% Senior Notes due February 15, 2028 400,000 — Bond discounts, premiums, and deferred issuance costs, net (8,501 ) (7,413 ) $ 2,861,375 $ 2,462,463 The senior notes are the unsecured obligations of Toll Brothers Finance Corp., our 100% -owned subsidiary. The payment of principal and interest is fully and unconditionally guaranteed, jointly and severally, by us and substantially all of our 100% -owned home building subsidiaries (together with Toll Brothers Finance Corp., the “Senior Note Parties”). The senior notes rank equally in right of payment with all the Senior Note Parties’ existing and future unsecured senior indebtedness, including the Revolving Credit Facility and the Term Loan Facility. The senior notes are structurally subordinated to the prior claims of creditors, including trade creditors, of our subsidiaries that are not guarantors of the senior notes. Each series of senior notes is redeemable in whole or in part at any time at our option, at prices that vary based upon the then-current rates of interest and the remaining original term of the senior notes to be redeemed. In January 2018, we issued $400.0 million aggregate principal amount of 4.350% Senior Notes due 2028. The Company received $396.4 million of net proceeds from the issuance of these senior notes. In October 2017, we repaid, at maturity, the $400.0 million of then-outstanding principal amount of 8.91% Senior Notes due October 15, 2017. On September 15, 2017 , we redeemed all $287.5 million aggregate principal amount of the 0.5% Exchangeable Senior Notes for cash at a redemption price of 100% of their principal amount, plus accrued and unpaid interest. The 0.5% Exchangeable Senior Notes were exchangeable into shares of our common stock at an exchange rate of 20.3749 shares per $1,000 principal amount of notes, corresponding to an initial exchange price of approximately $49.08 per share of common stock. If all of the 0.5% Exchangeable Senior Notes were exchanged, we would have issued approximately 5.9 million shares of our common stock. Shares issuable upon conversion of the 0.5% Exchangeable Senior Notes were included in the calculation of diluted earnings per share. In March 2017, we issued $300.0 million aggregate principal amount of 4.875% Senior Notes due 2027 (“ 4.875% Senior Notes due 2027”). The Company received $297.2 million of net proceeds from the issuance of these senior notes. In June 2017, we issued an additional $150.0 million principal amount of the 4.875% Senior Notes due 2027. These additional notes were issued at a premium of 103.655% of principal plus accrued interest. We received $156.4 million of net proceeds from the issuance of these additional notes. Subsequent event On November 30, 2018 , we redeemed, prior to maturity, the $350.0 million of then-outstanding principal amount of 4.00% Senior Notes due December 31, 2018 , at par, plus accrued interest. Mortgage Company Loan Facility In October 2017, TBI Mortgage ® Company (“TBI Mortgage”), our wholly owned mortgage subsidiary, entered into a mortgage warehousing agreement (“Warehousing Agreement”) with a bank to finance the origination of mortgage loans by TBI Mortgage. The Warehousing Agreement is accounted for as a secured borrowing under ASC 860, “Transfers and Servicing.” In December 2017, the Warehousing Agreement was amended to provide for loan purchases up to $75.0 million , subject to certain sublimits. Prior to this amendment, the Warehousing Agreement provided for loan purchases up to $100.0 million . In addition, the Warehousing Agreement, as amended, provides for an accordion feature under which TBI Mortgage may request that the aggregate commitments under the Warehousing Agreement be increased to an amount up to $150.0 million for a short period of time. The Warehousing Agreement, as amended, expires on December 6, 2018 , and borrowings thereunder bear interest at LIBOR plus 1.90% per annum. At October 31, 2018 , the interest rate on the Warehousing Agreement was 4.21% per annum. In addition, we are subject to an under usage fee based on outstanding balances, as defined in the Warehousing Agreement. Borrowings under this facility are included in the fiscal 2019 maturities. At October 31, 2018 and 2017 , there were $150.0 million and $120.1 million , respectively, outstanding under the Warehousing Agreement, which are included in liabilities in our Consolidated Balance Sheets. At October 31, 2018 and 2017 , amounts outstanding under the agreement were collateralized by $163.2 million and $125.7 million , respectively, of mortgage loans held for sale, which are included in assets in our Consolidated Balance Sheets. As of October 31, 2018 , there were no aggregate outstanding purchase price limitations reducing the amount available to TBI Mortgage. There are several restrictions on purchased loans under the agreement, including that they cannot be sold to others, they cannot be pledged to anyone other than the agent, and they cannot support any other borrowing or repurchase agreements. Subsequent event In December 2018, TBI Mortgage amended the Warehousing Agreement. As amended, the Warehousing Agreement provides for loan purchases up to $75.0 million , expires on December 6, 2019 , and provides for an accordion feature under which TBI Mortgage may request that the aggregate commitments under the Warehousing Agreement be increased to an amount up to $150.0 million for a short period of time. Borrowings will bear interest at LIBOR plus 1.90% per annum. General As of October 31, 2018 , the annual aggregate maturities of our loans and notes during each of the next five fiscal years are as follows (amounts in thousands): Amount 2019 $ 572,488 2020 $ 259,455 2021 $ 509,281 2022 $ 430,391 2023 $ 409,947

Accrued Expenses	Accrued Expenses Accrued expenses at October 31, 2018 and 2017 , consisted of the following (amounts in thousands): 2018 2017 Land, land development and construction $ 213,641 $ 146,168 Compensation and employee benefits 159,374 149,145 Escrow liability 32,543 45,209 Self-insurance 168,012 149,303 Warranty 258,831 329,278 Deferred income 42,179 42,798 Interest 40,325 36,035 Commitments to unconsolidated entities 10,553 8,870 Other 48,123 52,547 $ 973,581 $ 959,353 At the time each home is closed and title and possession are transferred to the home buyer, we record an initial accrual for expected warranty costs on that home. Our initial accrual for expected warranty costs is based upon historical warranty claim experience. Adjustments to our warranty liabilities related to homes delivered in prior periods are recorded in the period in which a change in our estimate occurs. The table below provides a reconciliation of the changes in our warranty accrual during fiscal 2018 , 2017 , and 2016 as follows (amounts in thousands): 2018 2017 2016 Balance, beginning of year $ 329,278 $ 370,992 $ 93,083 Additions - homes closed during the year 37,045 31,798 28,927 Addition - liabilities acquired 1,495 Increase in accruals for homes closed in prior years * 6,162 6,226 26,689 Reclassification from other accruals 1,082 Increase to water intrusion reserves ** 267,258 Charges incurred (113,654 ) (82,315 ) (44,965 ) Balance, end of year $ 258,831 $ 329,278 $ 370,992 * The fiscal 2016 amount included (i) a charge of $9.3 million , which is included in “Cost of revenues” in our 2016 Consolidated Statement of Operations and Comprehensive Income and (ii) $17.3 million of non-water intrusion warranty charges expected to be recovered from our insurance carriers and suppliers, which we recorded as a receivable at October 31, 2016 and is included in “Receivables, prepaid expenses, and other assets” on our 2016 Consolidated Balance Sheet. ** The fiscal 2016 amount included (i) a charge of $125.6 million , which is included in “Cost of revenues” in our 2016 Consolidated Statement of Operations and Comprehensive Income and (ii) $141.7 million of water intrusion warranty charges expected to be recovered from our insurance carriers and suppliers, which we recorded as a receivable at October 31, 2016 and is included in “Receivables, prepaid expenses, and other assets” on our 2016 Consolidated Balance Sheet. Since fiscal 2014, we have received water intrusion claims from owners of homes built since 2002 in communities located in Pennsylvania and Delaware (which are in our Mid-Atlantic region). During fiscal 2018, we continued to receive water intrusion claims from homeowners in this region, mostly related to older homes, and we continue to perform review procedures to assess, among other things, the number of affected homes, whether repairs are likely to be required, and the extent of such repairs. Our review process, conducted quarterly, includes an analysis of many factors applicable to these communities to determine whether a claim is likely to be received and the estimated costs to resolve any such claim, including: the closing dates of the homes; the number of claims received; our inspection of homes; an estimate of the number of homes we expect to repair; the type and cost of repairs that have been performed in each community; the estimated costs to remediate pending and future claims; the expected recovery from our insurance carriers and suppliers; and the previously recorded amounts related to these claims. We also monitor legal developments relating to these types of claims and review the volume, relative merits and adjudication of claims in litigation or arbitration. As of October 31, 2018, our recorded aggregate estimated repair costs to be incurred for known and unknown water intrusion claims was $324.4 million , which was unchanged from October 31, 2016, and our recorded aggregate expected recoveries from insurance carriers and suppliers were approximately $152.6 million , which was also unchanged from October 31, 2016. Our recorded remaining estimated repair costs, which reflects a reduction for the aggregate amount expended to resolve claims, were approximately $177.6 million at October 31, 2018 and $251.8 million at October 31, 2017. Our recorded remaining expected recoveries from insurance carriers and suppliers were approximately $109.3 million at October 31, 2018 and $127.6 million at October 31, 2017. As noted above, our review process includes a number of estimates that are based on assumptions with uncertain outcomes, including, but not limited to, the number of homes to be repaired, the extent of repairs needed, the repair procedures employed, the cost of those repairs, outcomes of litigation or arbitrations, and expected recoveries from insurance carriers and suppliers. Due to the degree of judgment required in making these estimates and the inherent uncertainty in potential outcomes, it is reasonably possible that our actual costs and recoveries could differ from those recorded and such differences could be material. In addition, due to such uncertainty we are unable to estimate the range of any such differences. We believe collection of our recorded insurance receivables is probable based on the legal merits that support our pending insurance claims and the high credit ratings of our insurance carriers; however, due to the complexity of the underlying claims and the variability of the other factors described above, it is reasonably possible that our actual insurance recoveries could materially differ from those recorded. Resolution of these known and unknown claims is expected to take several years.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The following table provides a reconciliation of our effective tax rate from the federal statutory tax rate for the fiscal years ended October 31, 2018 , 2017 , and 2016 ($ amounts in thousands): 2018 2017 2016 $ %* $ %* $ %* Federal tax provision at statutory rate 217,914 23.3 285,009 35.0 206,159 35.0 State tax provision, net of federal benefit 47,073 5.0 34,656 4.3 26,970 4.6 Domestic production activities deduction (18,168 ) (2.0 ) (12,835 ) (1.6 ) (16,874 ) (2.9 ) Other permanent differences (3,726 ) (0.4 ) (1,468 ) (0.2 ) (7,037 ) (1.2 ) Reversal of accrual for uncertain tax positions (4,741 ) (0.5 ) (3,981 ) (0.5 ) (11,177 ) (1.9 ) Accrued interest on anticipated tax assessments 737 0.1 984 0.1 1,964 0.3 Increase in unrecognized tax benefits 1,122 0.1 — — 2,052 0.3 Valuation allowance — recognized — — — — 1,018 0.2 Valuation allowance — reversed — — (32,154 ) (3.9 ) — — Changes in tax law (38,740 ) (4.1 ) — — — — Excess stock compensation benefit (4,236 ) (0.5 ) — — — — Other (11,470 ) (1.2 ) 8,605 1.1 3,857 0.7 Income tax provision* 185,765 19.9 278,816 34.2 206,932 35.1 * Due to rounding, amounts may not add. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law, which changed many longstanding foreign and domestic corporate and individual tax rules, as well as rules pertaining to the deductibility of employee compensation and benefits. The Tax Act, among other changes, reduced the corporate income tax rate from 35% to 21% and repealed the domestic production activities deduction effective for tax years beginning after December 31, 2017. For companies with a fiscal year that does not end on December 31, the change in law requires the application of a blended tax rate for the year of the change. Our blended tax rate for our fiscal year ending October 31, 2018 was 23.3% . Thereafter, the applicable statutory rate will be 21% . ASC 740, “Income Taxes” (“ASC 740”), requires all companies to reflect the effects of the new law in the period in which the law was enacted. Accordingly, we reduced the statutory tax rate applied to earnings from 35% in fiscal 2017 to 23.3% in fiscal 2018. In addition, we remeasured our net deferred tax liability for the tax law change, which resulted in an income tax benefit of $35.5 million in fiscal 2018. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the enactment date for companies to complete the accounting relating to the Tax Act under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in its financial statements. In connection with our analysis of the impact of the Tax Act through the nine months ended July 31, 2018, and in accordance with SAB 118, we recorded a provisional net tax benefit of $36.2 million related to the re-measurement of our net deferred tax liability based on the rates at which our deferred tax balances are expected to reverse in the future. As of October 31, 2018, we finalized our analysis of the impact and decreased the provisional net tax benefit by $0.7 million . We are subject to state tax in the jurisdictions in which we operate. We estimate our state tax liability based upon the individual taxing authorities’ regulations, estimates of income by taxing jurisdiction, and our ability to utilize certain tax-saving strategies. Based on our estimate of the allocation of income or loss among the various taxing jurisdictions and changes in tax regulations and their impact on our tax strategies, we estimated that our rate for state income taxes will be 6.6% in fiscal 2018 . Our state income tax rate was 6.5% and 7.1% in fiscal 2017 and 2016 , respectively. The following table provides information regarding the provision (benefit) for income taxes for each of the fiscal years ended October 31, 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 Federal $ 157,836 $ 278,095 $ 189,170 State 27,929 721 17,762 $ 185,765 $ 278,816 $ 206,932 Current $ 207,695 $ 93,106 $ 186,662 Deferred (21,930 ) 185,710 20,270 $ 185,765 $ 278,816 $ 206,932 The components of income taxes payable at October 31, 2018 and 2017 are set forth below (amounts in thousands): 2018 2017 Current $ 28,804 $ 33,100 Deferred 2,155 24,409 $ 30,959 $ 57,509 The following table provides a reconciliation of the change in the unrecognized tax benefits for the years ended October 31, 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 Balance, beginning of year $ 16,993 $ 30,272 $ 51,889 Increase in benefit as a result of tax positions taken in prior years 2,140 1,575 8,110 Increase in benefit as a result of tax positions taken in current year 949 431 694 Decrease in benefit as a result of settlements (4,707 ) (9,174 ) (28,976 ) Decrease in benefit as a result of lapse of statute of limitations (3,153 ) (6,111 ) (1,445 ) Balance, end of year $ 12,222 $ 16,993 $ 30,272 The statute of limitations has expired on our federal tax returns for fiscal years through 2014. Our unrecognized tax benefits are included in the current portion of “Income taxes payable” on our Consolidated Balance Sheets. If these unrecognized tax benefits reverse in the future, they would have a beneficial impact on our effective tax rate at that time. During the next 12 months, it is reasonably possible that the amount of unrecognized tax benefits will change, but we are not able to provide a range of such change. The anticipated changes will be principally due to the expiration of tax statutes, settlements with taxing jurisdictions, increases due to new tax positions taken, and the accrual of estimated interest and penalties. The amounts accrued for interest and penalties are included in the current portion of “Income taxes payable” on our Consolidated Balance Sheets. The following table provides information as to the amounts recognized in our tax provision, before reduction for applicable taxes and reversal of previously accrued interest and penalties, of potential interest and penalties in the fiscal years ended October 31, 2018 , 2017 , and 2016 , and the amounts accrued for potential interest and penalties at October 31, 2018 and 2017 (amounts in thousands): Expense recognized in the Consolidated Statements of Operations and Comprehensive Income Fiscal year 2018 $ 1,152 2017 $ 1,513 2016 $ 3,426 Accrued at: October 31, 2018 $ 2,115 October 31, 2017 $ 5,179 The components of net deferred tax assets and liabilities at October 31, 2018 and 2017 are set forth below (amounts in thousands): 2018 2017 Deferred tax assets: Accrued expenses $ 54,531 $ 88,527 Impairment charges 51,124 84,534 Inventory valuation differences 42,765 80,224 Stock-based compensation expense 27,949 41,712 Amounts related to unrecognized tax benefits 1,197 3,800 State tax, net operating loss carryforwards 73,288 48,343 Other 125 1,303 Total assets 250,979 348,443 Deferred tax liabilities: Capitalized interest 43,982 76,914 Deferred income 181,839 261,286 Expenses taken for tax purposes not for book 5,477 9,878 Depreciation 6,877 4,694 Deferred marketing 14,959 20,080 Total liabilities 253,134 372,852 Net deferred tax liabilities (2,155 ) (24,409 ) In accordance with GAAP, we assess whether a valuation allowance should be established based on our determination of whether it is more-likely-than-not that some portion or all of the deferred tax assets would not be realized. At October 31, 2018 and 2017 , we determined that it was more-likely-than-not that our deferred assets would be realized for federal purposes. Accordingly, at October 31, 2018 and 2017 , we did not have valuation allowances recorded against our federal or state deferred tax assets. We file tax returns in the various states in which we do business. Each state has its own statutes regarding the use of tax loss carryforwards. Some of the states in which we do business do not allow for the carryforward of losses, while others allow for carryforwards for 5 years to 20 years . For state tax purposes, we establish valuation allowances for deferred tax assets in certain jurisdictions where it is more-likely-than-not that the deferred tax asset would not be realized. Due to past and projected losses in certain jurisdictions where we did not have carryback potential and/or could not sufficiently forecast future taxable income, we recognized a net cumulative valuation allowance against our state deferred tax assets at October 31, 2016. During fiscal 2016 , we recognized new valuation allowances of $1.0 million . We did not recognize any new valuation allowances in fiscal 2018 and 2017 . During fiscal 2017 , due to improved operating results, we reversed $32.2 million of state deferred tax asset valuation allowances. No state deferred tax asset valuation allowances were reversed in fiscal 2018 and 2016 .

Stockholders' Equity Note [Abstract]
Stock Issuance and Stock Repurchase Program	Stockholders’ Equity Our authorized capital stock consists of 400 million shares of common stock, $0.01 par value per share (“common stock”), and 15 million shares of preferred stock, $0.01 par value per share. At October 31, 2018 , we had 146.2 million shares of common stock issued and outstanding, 7.3 million shares of common stock reserved for outstanding stock options and restricted stock units, 5.1 million shares of common stock reserved for future stock option and award issuances, and 0.4 million shares of common stock reserved for issuance under our employee stock purchase plan. As of October 31, 2018 , no shares of preferred stock have been issued. Cash Dividends On February 21, 2017, our Board of Directors approved the initiation of quarterly cash dividends to shareholders. During the fiscal years ended October 31, 2018 and October 31, 2017 , we declared and paid aggregate cash dividends of $0.41 and $0.24 per share, respectively, to our shareholders. Subsequent to October 31, 2018 , we declared a quarterly cash dividend of $0.11 which will be paid on January 25, 2019 to shareholders of record on the close of business on January 11, 2019. Stock Repurchase Program On May 23, 2016, our Board of Directors authorized, under a new repurchase program that replaced an existing program, the repurchase of 20 million shares of our common stock in open market transactions or otherwise for general corporate purposes, including to obtain shares for the Company’s equity award and other employee benefit plans. On December 13, 2017, our Board of Directors terminated our May 2016 share repurchase program and authorized, under a new repurchase program, the repurchase of 20 million shares of our common stock in open market transactions or otherwise for general corporate purposes, including to obtain shares for the Company’s equity award and other employee benefit plans. Our Board of Directors terminated, effective December 12, 2018, our December 2017 share repurchase program and authorized a new repurchase program described below. The following table provides information about the share repurchase programs for the fiscal years ended October 31, 2018 , 2017 , and 2016 : 2018 2017 2016 Number of shares purchased (in thousands) 12,108 7,694 13,652 Average price per share $ 41.56 $ 37.81 $ 28.77 Remaining authorization at October 31 (in thousands) 10,989 8,144 15,838 On December 12, 2018, our Board of Directors authorized the repurchase of 20 million shares of our common stock in open market transactions or otherwise for general corporate purposes, including to obtain shares for the Company’s equity award and other employee benefit plans. The Board of Directors did not fix any expiration date for this repurchase program. Subsequent to October 31, 2018 , we repurchased approximately 783,000 shares of our common stock at an average price of $32.02 per share, of which approximately 210,000 shares were purchased under the repurchase program authorized by our Board of Directors on December 12, 2018. Transfer Restriction On March 17, 2010 , our Board of Directors adopted a Certificate of Amendment to the Second Restated Certificate of Incorporation of the Company (the “Certificate of Amendment”). The Certificate of Amendment includes an amendment approved by our stockholders at the 2010 Annual Meeting of Stockholders that restricts certain transfers of our common stock. The Certificate of Amendment’s transfer restrictions generally restrict any direct or indirect transfer of our common stock if the effect would be to increase the direct or indirect ownership of any Person (as defined in the Certificate of Amendment) from less than 4.95% to 4.95% or more of our common stock or increase the ownership percentage of a Person owning or deemed to own 4.95% or more of our common stock. Any direct or indirect transfer attempted in violation of this restriction would be void as of the date of the prohibited transfer as to the purported transferee.

Stock-Based Benefit Plans [Abstract]
Stock-Based Benefit Plans	Stock-Based Benefit Plans We grant stock options, restricted stock, and various types of restricted stock units to our employees and our nonemployee directors under our stock incentive plans. We have two active stock incentive plans, one for employees (including officers) and one for nonemployee directors. Our active stock incentive plans provide for the granting of incentive stock options (solely to employees) and nonqualified stock options with a term of up to 10 years at a price not less than the market price of the stock at the date of grant. Our active stock incentive plans also provide for the issuance of stock appreciation rights and restricted and unrestricted stock awards and stock units, which may be performance-based. At October 31, 2018 , 2017 , and 2016 , we had 5.1 million ; 5.8 million ; and 6.8 million shares, respectively, available for grant under our stock incentive plans. We have two additional stock incentive plans for employees, officers, and directors that are inactive except for outstanding stock option awards at October 31, 2018 . No additional equity awards may be granted under these plans. Stock options granted under these plans were made with a term of up to 10 years at a price not less than the market price of the stock at the date of grant and generally vested over a four-year period for employees and a two-year period for nonemployee directors. The following table provides information regarding the amount of total stock-based compensation expense recognized by us for fiscal 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 Total stock-based compensation expense recognized $ 28,312 $ 28,466 $ 26,679 Income tax benefit recognized $ 7,902 $ 11,125 $ 10,450 At October 31, 2018 , 2017 , and 2016 , the aggregate unamortized value of outstanding stock-based compensation awards was approximately $20.9 million , $24.2 million , and $27.0 million , respectively. Information about our more significant stock-based compensation programs is outlined below. Stock Options: Stock options granted to employees generally vest over a four-year period, although certain grants may vest over a longer or shorter period. Stock options granted to nonemployee directors generally vest over a two-year period. Shares issued upon the exercise of a stock option are either from shares held in treasury or newly issued shares. The fair value of each option award is estimated on the date of grant using a lattice-based option valuation model that uses ranges of assumptions noted in the following table. Expected volatilities were based on implied volatilities from traded options on our stock, historical volatility of our stock, and other factors. The expected lives of options granted were derived from the historical exercise patterns and anticipated future patterns and represent the period of time that options granted are expected to be outstanding; the range given below results from certain groups of employees exhibiting different behaviors. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The following table summarizes the weighted-average assumptions and fair value used for stock option grants in each of the fiscal years ended October 31, 2018 , 2017 , and 2016 : 2018 2017 2016 Expected volatility 27.66% - 31.83% 29.93% - 41.05% 32.03% - 42.31% Weighted-average volatility 30.33% 34.72% 34.69% Risk-free interest rate 2.17% - 2.35% 1.96% - 2.52% 1.58% - 2.14% Expected life (years) 5.00 - 8.50 4.60 - 9.24 4.56 - 9.17 Dividends 0.67% none none Weighted-average fair value per share of options granted $16.09 $12.16 $11.24 The fair value of stock option grants is recognized evenly over the vesting period of the options or over the period between the grant date and the time the option becomes nonforfeitable by the employee, whichever is shorter. Information regarding the stock compensation expense related to stock options for fiscal 2018 , 2017 and 2016 was as follows (amounts in thousands): 2018 2017 2016 Stock compensation expense recognized - options $ 7,497 $ 10,337 $ 10,986 At October 31, 2018 , total compensation cost related to nonvested stock option awards not yet recognized was approximately $6.5 million , and the weighted-average period over which we expect to recognize such compensation costs was approximately 1.5 years . The following table summarizes stock option activity for our plans during each of the fiscal years ended October 31, 2018 , 2017 , and 2016 (amounts in thousands, except per share amounts): 2018 2017 2016 Number of options Weighted- average exercise price Number of options Weighted- average exercise price Number of options Weighted- average exercise price Balance, beginning 6,120 $ 27.60 8,514 $ 26.36 8,025 $ 25.75 Granted 210 47.84 595 31.61 965 32.85 Exercised (797 ) 24.16 (2,863 ) 24.54 (255 ) 24.04 Canceled (30 ) 33.08 (126 ) 32.10 (221 ) 35.23 Balance, ending 5,503 $ 28.84 6,120 $ 27.60 8,514 $ 26.36 Options exercisable, at October 31, 4,231 $ 27.03 4,266 $ 25.42 6,407 $ 24.14 The weighted average remaining contractual life (in years) for options outstanding and exercisable at October 31, 2018 , was 4.8 and 4.0 , respectively. The intrinsic value of options outstanding and exercisable is the difference between the fair market value of our common stock on the applicable date (“Measurement Value”) and the exercise price of those options that had an exercise price that was less than the Measurement Value. The intrinsic value of options exercised is the difference between the fair market value of our common stock on the date of exercise and the exercise price. The following table provides information pertaining to the intrinsic value of options outstanding and exercisable at October 31, 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 Intrinsic value of options outstanding $ 30,477 $ 112,886 $ 31,852 Intrinsic value of options exercisable $ 29,010 $ 87,978 $ 31,852 Information pertaining to the intrinsic value of options exercised and the fair market value of options that became vested or modified in each of the fiscal years ended October 31, 2018 , 2017 , and 2016 , is provided below (amounts in thousands): 2018 2017 2016 Intrinsic value of options exercised $ 18,165 $ 32,951 $ 2,337 Fair market value of options vested $ 10,007 $ 10,897 $ 9,690 Our stock option plans permit optionees to exercise stock options using a “net exercise” method at the discretion of the Executive Compensation Committee of the Board of Directors (“Executive Compensation Committee”). In a net exercise, we withhold from the total number of shares that otherwise would be issued to an optionee upon exercise of the stock option that number of shares having a fair market value at the time of exercise equal to the option exercise price and applicable minimum income tax withholdings and remit the remaining shares to the optionee. In fiscal 2018, the net exercise method was not utilized to exercise options. The following table provides information regarding the use of the net exercise method for fiscal 2017 and 2016 : 2017 2016 Options exercised 15,000 5,000 Shares withheld 14,472 3,547 Shares issued 528 1,453 Average fair market value per share withheld $ 32.98 $ 32.85 Aggregate fair market value of shares withheld (in thousands) $ 477 $ 117 Performance-Based Restricted Stock Units: In fiscal 2018 , 2017 , and 2016 , the Executive Compensation Committee approved awards of performance-based restricted stock units (“Performance-Based RSUs”) relating to shares of our common stock to certain members of our senior management. The number of shares earned for Performance-Based RSUs are based on the attainment of certain performance metrics approved by the Executive Compensation Committee in the year of grant. The number of shares underlying the Performance-Based RSUs that may be issued to the recipients ranges from 0% to 110% of the base award depending on actual achievement as compared to the target performance goals. Shares earned based on actual performance generally vest pro-rata over a four-year period provided the recipients continue to be employed by us as specified in the award document. The value of the Performance-Based RSUs was determined to be equal to the estimated number of shares of our common stock to be issued multiplied by the closing price of our common stock on the New York Stock Exchange (“NYSE”) on the date the Performance-Based RSU awards were approved by the Executive Compensation Committee (“Valuation Date”). We evaluate the performance goals quarterly and estimate the number of shares underlying the Performance-Based RSUs that are probable of being issued. The following table provides information regarding the issuance, valuation assumptions, and amortization of the Performance-Based RSUs issued in fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Number of shares underlying Performance-Based RSUs to be issued 135,554 168,417 182,854 Aggregate number of Performance-Based RSUs outstanding at October 31 786,857 940,117 1,074,222 Closing price of our common stock on Valuation Date $ 47.84 $ 31.61 $ 32.85 Aggregate grant date fair value of Performance-Based RSUs issued (in thousands) $ 6,485 $ 5,324 $ 6,007 Performance-Based RSU expense recognized (in thousands) $ 6,949 $ 7,031 $ 8,301 Unamortized value of Performance-Based RSUs at October 31 (in thousands) $ 3,824 $ 4,599 $ 6,556 Shares earned with respect to Performance-Based RSUs issued in December 2011, 2012, and 2013 were delivered in fiscal 2016, 2017, and 2018, respectively. The recipients of these Performance-Based RSUs elected to use a portion of the shares underlying the Performance-Based RSUs to pay the required income withholding taxes on the payout. In fiscal 2018, the gross value of the payout was $13.7 million ( 288,814 shares), the minimum income tax withholding was $6.0 million ( 126,330 shares) and the net value of the shares delivered was $7.7 million ( 162,484 shares). In fiscal 2017, the gross value of the payout was $9.6 million ( 302,514 shares), the minimum income tax withholding was $4.2 million ( 133,098 shares) and the net value of the shares delivered was $5.4 million ( 169,416 shares). In fiscal 2016, the gross value of the payout was $12.2 million ( 370,171 shares), the minimum income tax withholding was $5.4 million ( 164,090 shares) and the net value of the shares delivered was $6.8 million ( 206,081 shares). Total Shareholder Return Restricted Stock Units: In fiscal 2018 , 2017 , and 2016 , the Executive Compensation Committee approved awards of relative total shareholder return performance-based restricted stock units (“TSR RSUs”) relating to 39,411 , 46,361 and 171,705 target shares, respectively, of our common stock to certain members of our senior management. Shares underlying the TSR RSUs granted are earned by comparing our total shareholder return during specified performance periods to the total shareholder returns of companies in a performance peer group as defined in the award document. The specified performance periods are as follows: Performance Period Target Number of TSR RSUs issued Fiscal 2018 November 1, 2017 to October 31, 2020 39,411 Fiscal 2017 November 1, 2016 to October 31, 2019 46,361 Fiscal 2016 Tranche 1 (one-year) November 1, 2015 to October 31, 2016 61,796 Tranche 2 (two-year) November 1, 2015 to October 31, 2017 57,230 Tranche 3 (three-year) November 1, 2015 to October 31, 2018 52,679 The TSR RSUs generally vest at the end of a three -year period provided the recipients continue to be employed by us as specified in the award document. Based upon our ranking in the performance peer group, the recipient of the TSR RSUs may earn a total award ranging from 0% to 200% of the target number of TSR RSUs granted. In fiscal 2018, recipients of Tranche 3 TSR RSUs earned 76.81% of the target based upon our total shareholder return ranking in the performance peer group during the three-year period ended October 31, 2018. In fiscal 2017, recipients of Tranche 2 TSR RSUs earned 83.05% of the target based upon our total shareholder return ranking in the performance peer group during the two-year period ended October 31, 2017. In fiscal 2016, recipients of Tranche 1 TSR RSUs earned 0% of the target based upon our total shareholder return ranking in the performance peer group during the one-year period ended October 31, 2016. We estimated the fair value of the TSR RSUs at the grant date using a Monte Carlo simulation. The following table summarizes the assumptions used in the Monte Carlo simulation and the fair value per share of the TSR RSUs granted in fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Weighted-average volatility 26.58% 26.91% 28.66% Risk-free interest rate 1.92% 1.52% 1.23% Dividends none none none Weighted-average fair value per share of TSR RSUs $52.62 $39.21 $41.16 The length of each performance period was used as the expected term in the simulation for each respective tranche. The following table provides information on expense recognized and the unamortized value of our TSR RSUs for fiscal 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 TSR RSUs expense recognized $ 2,502 $ 3,400 $ 3,300 Unamortized value of TSR RSUs at October 31 $ 1,773 $ 2,200 $ 3,800 Time-Based Restricted Stock Units: In fiscal 2018 , 2017 , and 2016 , we issued time-based restricted stock units (“RSUs”) to various officers, employees, and nonemployee directors. These RSUs generally vest in annual installments over a two- to four-year period. The value of the RSUs was determined to be equal to the number of shares of our common stock underlying the RSUs multiplied by the closing price of our common stock on the NYSE on the date the RSUs were awarded. The following table provides information regarding these RSUs for fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Time-Based RSUs issued: Number of RSUs issued 296,790 377,564 139,684 Weighted average closing price per share of our common stock on date of issuance $ 47.84 $ 31.61 $ 32.85 Aggregate fair value of RSUs issued (in thousands) $ 14,198 $ 11,935 $ 4,589 Time-Based RSU expense recognized (in thousands): $ 11,193 $ 7,572 $ 3,958 2018 2017 2016 At October 31: Aggregate number of Time-Based RSUs outstanding 850,853 673,224 396,716 Cumulative unamortized value of Time-Based RSUs (in thousands) $ 8,818 $ 6,783 $ 2,956 Our stock incentive plans permit us to withhold from the total number of shares that otherwise would be issued to a restricted stock unit recipient upon distribution that number of shares having a fair value at the time of distribution equal to the applicable income tax withholdings due and remit the remaining shares to the restricted stock unit recipient. The following table provides information regarding the number of shares withheld, the income tax withholding due, and the remaining shares issued to the recipients for fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Number of shares withheld 23,289 20,400 25,340 Income tax withholdings due $ 1,145 $ 664,300 $ 827,800 Remaining shares issued to the recipients 58,552 52,757 70,627 Employee Stock Purchase Plan Our employee stock purchase plan enables substantially all employees to purchase our common stock at 95% of the market price of the stock on specified offering dates without restriction or at 85% of the market price of the stock on specified offering dates subject to restrictions. The plan, which terminates in December 2027, provides that 500,000 shares be reserved for purchase. At October 31, 2018 , 448,000 shares were available for issuance.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures Financial Instruments A summary of assets and (liabilities) at October 31, 2018 and 2017 , related to our financial instruments, measured at fair value on a recurring basis, is set forth below (amounts in thousands): Fair value Financial Instrument Fair value hierarchy October 31, 2018 October 31, 2017 Residential Mortgage Loans Held for Sale Level 2 $ 170,731 $ 132,922 Forward Loan Commitments – Residential Mortgage Loans Held for Sale Level 2 $ 1,750 $ 861 Interest Rate Lock Commitments (“IRLCs”) Level 2 $ (4,366 ) $ (1,293 ) Forward Loan Commitments – IRLCs Level 2 $ 4,366 $ 1,293 At October 31, 2018 and 2017 , the carrying value of cash and cash equivalents approximated fair value. Mortgage Loans Held for Sale At the end of the reporting period, we determine the fair value of our mortgage loans held for sale and the forward loan commitments we have entered into as a hedge against the interest rate risk of our mortgage loans and commitments using the market approach to determine fair value. The evaluation is based on the current market pricing of mortgage loans with similar terms and values as of the reporting date and the application of such pricing to the mortgage loan portfolio. We recognize the difference between the fair value and the unpaid principal balance of mortgage loans held for sale as a gain or loss. In addition, we recognize the fair value of our forward loan commitments as a gain or loss. These gains and losses are included in “Other income – net” in our Consolidated Statements of Operations and Comprehensive Income. Interest income on mortgage loans held for sale is calculated based upon the stated interest rate of each loan and is also included in “Other income – net.” The table below provides, for the periods indicated, the aggregate unpaid principal and fair value of mortgage loans held for sale as of the date indicated (amounts in thousands): At October 31, Aggregate unpaid principal balance Fair value Excess 2018 $ 170,728 $ 170,731 $ 3 2017 $ 131,861 $ 132,922 $ 1,061 IRLCs represent individual borrower agreements that commit us to lend at a specified price for a specified period as long as there is no violation of any condition established in the commitment contract. These commitments have varying degrees of interest rate risk. We utilize best-efforts forward loan commitments (“Forward Commitments”) to hedge the interest rate risk of the IRLCs and residential mortgage loans held for sale. Forward Commitments represent contracts with third-party investors for the future delivery of loans whereby we agree to make delivery at a specified future date at a specified price. The IRLCs and Forward Commitments are considered derivative financial instruments under ASC 815, “Derivatives and Hedging,” which requires derivative financial instruments to be recorded at fair value. We estimate the fair value of such commitments based on the estimated fair value of the underlying mortgage loan and, in the case of IRLCs, the probability that the mortgage loan will fund within the terms of the IRLC. The fair values of IRLCs and forward loan commitments are included in either “Receivables, prepaid expenses and other assets” or “Accrued expenses” in our Consolidated Balance Sheets, as appropriate. To manage the risk of non-performance of investors regarding the Forward Commitments, we assess the creditworthiness of the investors on a periodic basis. Inventory We recognize inventory impairment charges based on the difference in the carrying value of the inventory and its fair value at the time of the evaluation. The fair value of the aforementioned inventory was determined using Level 3 criteria. Estimated fair value is primarily determined by discounting the estimated future cash flow of each community. See Note 1, “Significant Accounting Policies - Inventory,” for additional information regarding our methodology on determining fair value. As further discussed in Note 1, determining the fair value of a community’s inventory involves a number of variables, many of which are interrelated. If we used a different input for any of the various unobservable inputs used in our impairment analysis, the results of the analysis may have been different, absent any other changes. The table below summarizes, for the periods indicated, the ranges of certain quantitative unobservable inputs utilized in determining the fair value of impaired communities: Three months ended: Selling price per unit ($ in thousands) Sales pace per year (in units) Discount rate Fiscal 2018: January 31 381 - 1,029 7 - 10 13.8% - 19.0% April 30 485 - 522 10 - 16 16.9% July 31 (1) – – – October 31 470 - 1071 4 - 23 13.5% - 16.3% Fiscal 2017: January 31 692 - 880 4 - 12 16.3% April 30 827 - 856 6 - 11 16.3% July 31 465 - 754 3 - 10 16.5% - 19.5% October 31 467 - 540 12 - 30 16.4% (1) The impairment charges recognized were related to our decisions to sell lots in a bulk sale in certain communities rather than sell and construct homes as previously intended. The sale price per lot used in the fair value determination for these bulk sales ranged from $10,000 to $155,000 . The table below provides, for the periods indicated, the number of operating communities that we reviewed for potential impairment, the number of operating communities in which we recognized impairment charges, the amount of impairment charges recognized, and, as of the end of the period indicated, the fair value of those communities, net of impairment charges ($ amounts in thousands): Impaired operating communities Three months ended: Number of Number of communities Fair value of Impairment charges recognized Fiscal 2018: January 31 64 5 $ 13,318 $ 3,736 April 30 65 4 $ 21,811 13,325 July 31 55 5 $ 43,063 9,065 October 31 43 6 $ 24,692 4,025 $ 30,151 Fiscal 2017: January 31 57 2 $ 8,372 $ 4,000 April 30 46 6 $ 25,092 2,935 July 31 53 4 $ 5,965 1,360 October 31 51 1 $ 6,982 1,500 $ 9,795 Fiscal 2016: January 31 43 2 $ 1,713 $ 600 April 30 41 2 $ 10,103 6,100 July 31 51 2 $ 11,714 1,250 October 31 59 2 $ 1,126 415 $ 8,365 Debt The table below provides, as of the dates indicated, the book value and estimated fair value of our debt at October 31, 2018 and 2017 (amounts in thousands): 2018 2017 Fair value hierarchy Book value Estimated fair value Book value Estimated fair value Loans payable (a) Level 2 $ 688,115 $ 687,974 $ 639,116 $ 639,088 Senior notes (b) Level 1 2,869,876 2,779,270 2,469,876 2,626,131 Mortgage company loan facility (c) Level 2 150,000 150,000 120,145 120,145 $ 3,707,991 $ 3,617,244 $ 3,229,137 $ 3,385,364 (a) The estimated fair value of loans payable was based upon contractual cash flows discounted at interest rates that we believed were available to us for loans with similar terms and remaining maturities as of the applicable valuation date.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits Disclosure	Employee Retirement and Deferred Compensation Plans Salary Deferral Savings Plans We maintain salary deferral savings plans covering substantially all employees. We recognized an expense, net of plan forfeitures, with respect to the plans of $12.6 million , $12.3 million , and $10.3 million for the fiscal years ended October 31, 2018 , 2017 , and 2016 , respectively. Deferred Compensation Plan We have an unfunded, nonqualified deferred compensation plan that permits eligible employees to defer a portion of their compensation. The deferred compensation, together with certain of our contributions, earns various rates of return depending upon when the compensation was deferred. A portion of the deferred compensation and interest earned may be forfeited by a participant if he or she elects to withdraw the compensation prior to the end of the deferral period. We accrued $27.0 million and $23.2 million at October 31, 2018 and 2017 , respectively, for our obligations under the plan. Defined Benefit Retirement Plans We have two unfunded defined benefit retirement plans. Retirement benefits generally vest when the participant reaches normal retirement age (age 62 ). Unrecognized prior service costs are being amortized over the period from the date participants enter the plans until their interests are fully vested. We used a 4.06% , 3.19% , and 2.98% discount rate in our calculation of the present value of our projected benefit obligations at October 31, 2018 , 2017 , and 2016 , respectively. The rates represent the approximate long-term investment rate at October 31 of the fiscal year for which the present value was calculated. Information related to the plans is based on actuarial information calculated as of October 31, 2018 , 2017 and 2016 . Information related to our retirement plans for each of the fiscal years ended October 31, 2018 , 2017 , and 2016 , is as follows (amounts in thousands): 2018 2017 2016 Plan costs: Service cost $ 568 $ 619 $ 562 Interest cost 1,198 1,142 1,276 Amortization of prior service cost 936 969 947 Amortization of unrecognized losses 17 137 42 $ 2,719 $ 2,867 $ 2,827 Projected benefit obligation: Beginning of year $ 38,222 $ 38,980 $ 35,815 Plan amendments adopted during year 757 Service cost 568 619 562 Interest cost 1,198 1,142 1,276 Benefit payments (1,358 ) (1,318 ) (1,129 ) Change in unrecognized gain/loss (3,115 ) (1,201 ) 1,699 Projected benefit obligation, end of year $ 35,515 $ 38,222 $ 38,980 Unamortized prior service cost: Beginning of year $ 1,806 $ 2,775 $ 2,965 Plan amendments adopted during year 757 Amortization of prior service cost (936 ) (969 ) (947 ) Unamortized prior service cost, end of year $ 870 $ 1,806 $ 2,775 Accumulated unrecognized gain (loss), October 31 $ 1,571 $ (1,560 ) $ (2,898 ) Accumulated benefit obligation, October 31 $ 35,515 $ 38,222 $ 38,980 Accrued benefit obligation, October 31 $ 35,515 $ 38,222 $ 38,980 The accrued benefit obligation is included in accrued expenses on our Consolidated Balance Sheets.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings We are involved in various claims and litigation arising principally in the ordinary course of business. We believe that adequate provision for resolution of all current claims and pending litigation has been made and that the disposition of these matters will not have a material adverse effect on our results of operations and liquidity or on our financial condition. In April 2017, the SEC informed the Company that it was conducting an investigation and requested that we voluntarily produce documents and information relating to our estimated repair costs for stucco and other water intrusion claims in fiscal 2016. The Company produced detailed information and documents in response to this request and, in the fourth quarter of fiscal 2018, the SEC notified the Company that it had concluded its investigation without action. See Note 7 – “Accrued Expenses” for additional information regarding these warranty charges. In March 2018, the Pennsylvania Attorney General informed the Company that it was conducting a review of our construction of stucco homes in Pennsylvania after January 1, 2005 and requested that we voluntarily produce documents and information. The Company is producing documents and information in response to this request. Management cannot at this time predict the eventual scope or outcome of this matter. Land Purchase Commitments Generally, our purchase agreements to acquire land parcels do not require us to purchase those land parcels, although we, in some cases, forfeit any deposit balance outstanding if and when we terminate a purchase agreement. If market conditions are weak, approvals needed to develop the land are uncertain, or other factors exist that make the purchase undesirable, we may choose not to acquire the land. Whether a purchase agreement is legally terminated or not, we review the amount recorded for the land parcel subject to the purchase agreement to determine whether the amount is recoverable. While we may not have formally terminated the purchase agreements for those land parcels that we do not expect to acquire, we write off any nonrefundable deposits and costs previously capitalized to such land parcels in the periods that we determine such costs are not recoverable. Information regarding our land purchase commitments at October 31, 2018 and 2017 , is provided in the table below (amounts in thousands): 2018 2017 Aggregate purchase commitments: Unrelated parties $ 2,404,660 $ 1,986,276 Unconsolidated entities that the Company has investments in 128,235 248,801 Total $ 2,532,895 $ 2,235,077 Deposits against aggregate purchase commitments $ 168,421 $ 97,706 Credits to be received from unconsolidated entities 79,168 134,630 Additional cash required to acquire land 2,285,306 2,002,741 Total $ 2,532,895 $ 2,235,077 Amount of additional cash required to acquire land included in accrued expenses $ 40,103 $ 4,329 In addition, we expect to purchase approximately 2,700 additional home sites over a number of years from several joint ventures in which we have investments; the purchase prices of these home sites will be determined at a future date. At October 31, 2018 , we also had purchase commitments to acquire land for apartment developments of approximately $272.6 million , of which we had outstanding deposits in the amount of $13.2 million . We have additional land parcels under option that have been excluded from the aforementioned aggregate purchase amounts since we do not believe that we will complete the purchase of these land parcels and no additional funds will be required from us to terminate these contracts. Investments in Unconsolidated Entities At October 31, 2018 , we had investments in a number of unconsolidated entities, were committed to invest or advance additional funds, and had guaranteed a portion of the indebtedness and/or loan commitments of these entities. See Note 4, “Investments in Unconsolidated Entities,” for more information regarding our commitments to these entities. Surety Bonds and Letters of Credit At October 31, 2018 , we had outstanding surety bonds amounting to $692.9 million , primarily related to our obligations to governmental entities to construct improvements in our communities. We estimate that $342.2 million of work remains on these improvements. We have an additional $160.2 million of surety bonds outstanding that guarantee other obligations. We do not believe it is probable that any outstanding bonds will be drawn upon. At October 31, 2018 , we had outstanding letters of credit of $165.4 million under our Revolving Credit Facility. These letters of credit were issued to secure our various financial obligations, including insurance policy deductibles and other claims, land deposits, and security to complete improvements in communities in which we are operating. We do not believe that it is probable that any outstanding letters of credit will be drawn upon. Backlog At October 31, 2018 , we had agreements of sale outstanding to deliver 6,105 homes with an aggregate sales value of $5.52 billion . Mortgage Commitments Our mortgage subsidiary provides mortgage financing for a portion of our home closings. For those home buyers to whom our mortgage subsidiary provides mortgages, we determine whether the home buyer qualifies for the mortgage based upon information provided by the home buyer and other sources. For those home buyers who qualify, our mortgage subsidiary provides the home buyer with a mortgage commitment that specifies the terms and conditions of a proposed mortgage loan based upon then-current market conditions. Prior to the actual closing of the home and funding of the mortgage, the home buyer will lock in an interest rate based upon the terms of the commitment. At the time of rate lock, our mortgage subsidiary agrees to sell the proposed mortgage loan to one of several outside recognized mortgage financing institutions (“investors”) that is willing to honor the terms and conditions, including interest rate, committed to the home buyer. We believe that these investors have adequate financial resources to honor their commitments to our mortgage subsidiary. Information regarding our mortgage commitments at October 31, 2018 and 2017 , is provided in the table below (amounts in thousands): 2018 2017 Aggregate mortgage loan commitments: IRLCs $ 614,255 $ 350,740 Non-IRLCs 1,329,674 1,146,872 Total $ 1,943,929 $ 1,497,612 Investor commitments to purchase: IRLCs $ 614,255 $ 350,740 Mortgage loans receivable 163,208 125,710 Total $ 777,463 $ 476,450 Lease Commitments We lease certain facilities and equipment under non-cancelable operating leases.

On one of these transactions, we recognized a gain of $1.0 million in fiscal 2018.

We will recognize the deferred gain into income as the guarantees provided expire. Land sale revenues for the year ended October 31, 2017 included $257.8 million related to sale transactions with two new Home Building Joint Ventures and a Rental Property Joint Venture in which we have interests ranging from 20% to 25% .

We recognized the gain as units were sold to the ultimate home buyers which is included in deferred gains recognized above. In the fourth quarter of fiscal 2017, we purchased the remaining inventory from this Home Building Joint Venture. The remaining unamortized deferred gain was used to reduce the basis of the inventory acquired. See Note 4, “Investments in Unconsolidated Entities,” for more information on these transactions. Subsequent event In December 2018, we sold one of our golf club properties to a third party for $18.5 million .

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Oct. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation Policy [Text Block]	Basis of Presentation The consolidated financial statements include the accounts of Toll Brothers, Inc. (the “Company,” “we,” “us,” or “our”), a Delaware corporation, and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Investments in 50% or less owned partnerships and affiliates are accounted for using the equity method unless it is determined that we have effective control of the entity, in which case we would consolidate the entity. References herein to fiscal year refer to our fiscal years ended or ending October 31.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Liquid investments or investments with original maturities of three months or less are classified as cash equivalents.
Inventory [Policy Text Block]	Inventory Inventory is stated at cost unless an impairment exists, in which case it is written down to fair value in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360, “Property, Plant, and Equipment” (“ASC 360”). In addition to direct land acquisition costs, land development costs, and home construction costs, costs also include interest, real estate taxes, and direct overhead related to development and construction, which are capitalized to inventory during the period beginning with the commencement of development and ending with the completion of construction. For those communities that have been temporarily closed, no additional capitalized interest is allocated to a community’s inventory until it reopens. While the community remains closed, carrying costs such as real estate taxes are expensed as incurred. We capitalize certain interest costs to qualified inventory during the development and construction period of our communities in accordance with ASC 835-20, “Capitalization of Interest” (“ASC 835-20”). Capitalized interest is charged to cost of revenues when the related inventory is delivered. Interest incurred on home building indebtedness in excess of qualified inventory, as defined in ASC 835-20, is charged to the Consolidated Statements of Operations and Comprehensive Income in the period incurred. Once a parcel of land has been approved for development and we open one of our typical communities, it may take four or more years to fully develop, sell, and deliver all the homes in such community. Longer or shorter time periods are possible depending on the number of home sites in a community and the sales and delivery pace of the homes in a community. Our master planned communities, consisting of several smaller communities, may take up to 10 years or more to complete. Because our inventory is considered a long-lived asset under GAAP, we are required, under ASC 360, to regularly review the carrying value of each community and write down the value of those communities for which we believe the values are not recoverable. Operating Communities : When the profitability of an operating community deteriorates, the sales pace declines significantly, or some other factor indicates a possible impairment in the recoverability of the asset, the asset is reviewed for impairment by comparing the estimated future undiscounted cash flow for the community to its carrying value. If the estimated future undiscounted cash flow is less than the community’s carrying value, the carrying value is written down to its estimated fair value. Estimated fair value is primarily determined by discounting the estimated future cash flow of each community. The impairment is charged to cost of revenues in the period in which the impairment is determined. In estimating the future undiscounted cash flow of a community, we use various estimates such as (i) the expected sales pace in a community, based upon general economic conditions that will have a short-term or long-term impact on the market in which the community is located and on competition within the market, including the number of home sites available and pricing and incentives being offered in other communities owned by us or by other builders; (ii) the expected sales prices and sales incentives to be offered in a community; (iii) costs expended to date and expected to be incurred in the future, including, but not limited to, land and land development, home construction, interest, and overhead costs; (iv) alternative product offerings that may be offered in a community that will have an impact on sales pace, sales price, building cost, or the number of homes that can be built on a particular site; and (v) alternative uses for the property such as the possibility of a sale of the entire community to another builder or the sale of individual home sites. Future Communities : We evaluate all land held for future communities or future sections of operating communities, whether owned or under contract, to determine whether or not we expect to proceed with the development of the land as originally contemplated. This evaluation encompasses the same types of estimates used for operating communities described above, as well as an evaluation of the regulatory environment applicable to the land and the estimated probability of obtaining the necessary approvals, the estimated time and cost it will take to obtain the approvals, and the possible concessions that may be required to be given in order to obtain them. Concessions may include cash payments to fund improvements to public places such as parks and streets, dedication of a portion of the property for use by the public or as open space, or a reduction in the density or size of the homes to be built. Based upon this review, we decide (i) as to land under contract to be purchased, whether the contract will likely be terminated or renegotiated, and (ii) as to land owned, whether the land will likely be developed as contemplated or in an alternative manner, or should be sold. We then further determine whether costs that have been capitalized to the community are recoverable or should be written off. The write-off is charged to cost of revenues in the period in which the need for the write-off is determined.
Capitalization of Interest Costs Policy [Text Block]	We capitalize certain interest costs to qualified inventory during the development and construction period of our communities in accordance with ASC 835-20, “Capitalization of Interest” (“ASC 835-20”). Capitalized interest is charged to cost of revenues when the related inventory is delivered. Interest incurred on home building indebtedness in excess of qualified inventory, as defined in ASC 835-20, is charged to the Consolidated Statements of Operations and Comprehensive Income in the period incurred.
Estimated fair values Policy [Text Block]	The estimates used in the determination of the estimated cash flows and fair value of both current and future communities are based on factors known to us at the time such estimates are made and our expectations of future operations and economic conditions. Should the estimates or expectations used in determining estimated fair value deteriorate in the future, we may be required to recognize additional impairment charges and write-offs related to current and future communities and such amounts could be material.
Consolidation, Policy [Policy Text Block]	Variable Interest Entities We are required to consolidate variable interest entities (“VIEs”) in which we have a controlling financial interest in accordance with ASC 810, “Consolidation” (“ASC 810”). A controlling financial interest will have both of the following characteristics: (i) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. Our variable interest in VIEs may be in the form of equity ownership, contracts to purchase assets, management services and development agreements between us and a VIE, loans provided by us to a VIE or other member, and/or guarantees provided by members to banks and other parties. We have a significant number of land purchase contracts and investments in unconsolidated entities which we evaluate in accordance with ASC 810. We analyze our land purchase contracts and the unconsolidated entities in which we have an investment to determine whether the land sellers and unconsolidated entities are VIEs and, if so, whether we are the primary beneficiary. We examine specific criteria and use our judgment when determining if we are the primary beneficiary of a VIE. Factors considered in determining whether we are the primary beneficiary include risk and reward sharing, experience and financial condition of other member(s), voting rights, involvement in day-to-day capital and operating decisions, representation on a VIE’s executive committee, existence of unilateral kick-out rights or voting rights, level of economic disproportionality between us and the other member(s), and contracts to purchase assets from VIEs. The determination whether an entity is a VIE and, if so, whether we are the primary beneficiary may require significant judgment.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Construction, and Office Equipment Property, construction, and office equipment are recorded at cost and are stated net of accumulated depreciation of $145.0 million and $126.1 million at October 31, 2018 and 2017 , respectively. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. In fiscal 2018 , 2017 , and 2016 , we recognized $21.0 million , $18.7 million , and $15.5 million of depreciation expense, respectively.
Mortgage Loans Held for Sale [Policy Text Block]	Mortgage Loans Held for Sale Residential mortgage loans held for sale are measured at fair value in accordance with the provisions of ASC 825, “Financial Instruments” (“ASC 825”). We believe the use of ASC 825 improves consistency of mortgage loan valuations between the date the borrower locks in the interest rate on the pending mortgage loan and the date of the mortgage loan sale. At the end of the reporting period, we determine the fair value of our mortgage loans held for sale and the forward loan commitments we have entered into as a hedge against the interest rate risk of our mortgage loans using the market approach to determine fair value. The evaluation is based on the current market pricing of mortgage loans with similar terms and values as of the reporting date, and such pricing is applied to the mortgage loan portfolio. We recognize the difference between the fair value and the unpaid principal balance of mortgage loans held for sale as a gain or loss. In addition, we recognize the fair value of our forward loan commitments as a gain or loss. Interest income on mortgage loans held for sale is calculated based upon the stated interest rate of each loan. In addition, the recognition of net origination costs and fees associated with residential mortgage loans originated are expensed as incurred. These gains and losses, interest income, and origination costs and fees are recognized in “Other income - net” in the Consolidated Statements of Operations and Comprehensive Income.
Investments in Unconsolidated Entities [Policy Text Block]	Investments in Unconsolidated Entities In accordance with ASC 323, “Investments—Equity Method and Joint Ventures,” we review each of our investments on a quarterly basis for indicators of impairment. A series of operating losses of an investee, the inability to recover our invested capital, or other factors may indicate that a loss in value of our investment in the unconsolidated entity has occurred. If a loss exists, we further review the investment to determine if the loss is other than temporary, in which case we write down the investment to its fair value. The evaluation of our investment in unconsolidated entities entails a detailed cash flow analysis using many estimates, including, but not limited to, expected sales pace, expected sales prices, expected incentives, costs incurred and anticipated, sufficiency of financing and capital, competition, market conditions, and anticipated cash receipts, in order to determine projected future distributions from the unconsolidated entity. In addition, for rental properties, we review rental trends, expected future expenses, and expected cash flows to determine estimated fair values of the properties. Our unconsolidated entities that develop land or develop for-sale homes and condominiums evaluate their inventory in a similar manner as we do. See “Inventory” above for more detailed disclosure on our evaluation of inventory. For our unconsolidated entities that own, develop, and manage for-rent residential apartments, we review rental trends, expected future expenses, and expected future cash flows to determine estimated fair values of the properties. If a valuation adjustment is recorded by an unconsolidated entity related to its assets, our proportionate share is reflected in income from unconsolidated entities with a corresponding decrease to our investment in unconsolidated entities. We are a party to several joint ventures with unrelated parties to develop and sell land that is owned by the joint ventures. We recognize our proportionate share of the earnings from the sale of home sites to other builders, including our joint venture partners. We do not recognize earnings from the home sites we purchase from these ventures at the time of purchase; instead, our cost basis in those home sites is reduced by our share of the earnings realized by the joint venture from sales of those home sites to us. We are also a party to several other joint ventures. We recognize our proportionate share of the earnings and losses of our unconsolidated entities.
Fair Value Disclosures [Policy Text Block]	Fair Value Disclosures We use ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), to measure the fair value of certain assets and liabilities. ASC 820 provides a framework for measuring fair value in accordance with GAAP, establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value, and requires certain disclosures about fair value measurements. The fair value hierarchy is summarized below: Level 1: Fair value determined based on quoted prices in active markets for identical assets or liabilities. Level 2: Fair value determined using significant observable inputs, generally either quoted prices in active markets for similar assets or liabilities or quoted prices in markets that are not active. Level 3: Fair value determined using significant unobservable inputs, such as pricing models, discounted cash flows, or similar techniques.
Treasury Stock Policy [Text Block]	Treasury Stock Treasury stock is recorded at cost. Issuance of treasury stock is accounted for on a first-in, first-out basis. Differences between the cost of treasury stock and the re-issuance proceeds are charged to additional paid-in capital.
Revenue Recognition, Policy [Policy Text Block]	Revenue and Cost Recognition Revenues and cost of revenues from home sales are recorded at the time each home is delivered and title and possession are transferred to the buyer. For our standard attached and detached homes, land, land development, and related costs, both incurred and estimated to be incurred in the future, are amortized to the cost of homes closed based upon the total number of homes to be constructed in each community. Any changes resulting from a change in the estimated number of homes to be constructed or in the estimated land, land development, and related costs subsequent to the commencement of delivery of homes are allocated to the remaining undelivered homes in the community. Home construction and related costs are charged to the cost of homes closed under the specific identification method. The estimated land, common area development, and related costs of master planned communities, including the cost of golf courses, net of their estimated residual value, are allocated to individual communities within a master planned community on a relative sales value basis. Any changes resulting from a change in the estimated number of homes to be constructed or in the estimated costs are allocated to the remaining home sites in each of the communities of the master planned community. For high-rise/mid-rise projects, land, land development, construction, and related costs, both incurred and estimated to be incurred in the future, are generally amortized to the cost of units closed based upon an estimated relative sales value of the units closed to the total estimated sales value. Any changes resulting from a change in the estimated total costs or revenues of the project are allocated to the remaining units to be delivered. Forfeited Customer Deposits: Forfeited customer deposits are recognized in “Other income – net” in our Consolidated Statements of Operations and Comprehensive Income in the period in which we determine that the customer will not complete the purchase of the home and we have the right to retain the deposit. Sales Incentives: In order to promote sales of our homes, we grant our home buyers sales incentives from time to time. These incentives will vary by type of incentive and by amount on a community-by-community and home-by-home basis. Incentives that impact the value of the home or the sales price paid, such as special or additional options, are generally reflected as a reduction in sales revenues. Incentives that we pay to an outside party, such as paying some or all of a home buyer’s closing costs, are recorded as an additional cost of revenues. Incentives are recognized at the time the home is delivered to the home buyer and we receive the sales proceeds.
Advertising Costs, Policy [Policy Text Block]	Advertising Costs We expense advertising costs as incurred. Advertising costs were $28.5 million , $26.1 million , and $23.1 million for the years ended October 31, 2018 , 2017 , and 2016 , respectively.
Warranty Costs Policy [Text Block]	Warranty and Self-Insurance Warranty: We provide all of our home buyers with a limited warranty as to workmanship and mechanical equipment. We also provide many of our home buyers with a limited 10 -year warranty as to structural integrity. We accrue for expected warranty costs at the time each home is closed and title and possession are transferred to the home buyer. Warranty costs are accrued based upon historical experience. Adjustments to our warranty liabilities related to homes delivered in prior periods are recorded in the period in which a change in our estimate occurs. Over the past several years, we have had a significant number of warranty claims related primarily to homes built in Pennsylvania and Delaware. See Note 7 – “Accrued Expenses” for additional information regarding these warranty charges.
Self-insurance [Text Block]	Self-Insurance: We maintain, and require the majority of our subcontractors to maintain, general liability insurance (including construction defect and bodily injury coverage) and workers’ compensation insurance. These insurance policies protect us against a portion of our risk of loss from claims related to our home building activities, subject to certain self-insured retentions, deductibles and other coverage limits (“self-insured liability”). We also provide general liability insurance for our subcontractors in Arizona, California, Colorado, Nevada, Washington, and certain areas of Texas, where eligible subcontractors are enrolled as insureds under our general liability insurance policies in each community in which they perform work. For those enrolled subcontractors, we absorb their general liability associated with the work performed on our homes within the applicable community as part of our overall general liability insurance and our self-insured liability. We record expenses and liabilities based on the estimated costs required to cover our self-insured liability and the estimated costs of potential claims and claim adjustment expenses that are above our coverage limits or that are not covered by our insurance policies. These estimated costs are based on an analysis of our historical claims and industry data, and include an estimate of claims incurred but not yet reported (“IBNR”). We engage a third-party actuary that uses our historical claim and expense data, input from our internal legal and risk management groups, as well as industry data, to estimate our liabilities related to unpaid claims, IBNR associated with the risks that we are assuming for our self-insured liability, and other required costs to administer current and expected claims. These estimates are subject to uncertainty due to a variety of factors, the most significant being the long period of time between the delivery of a home to a home buyer and when a structural warranty or construction defect claim may be made, and the ultimate resolution of the claim. Though state regulations vary, construction defect claims may be reported and resolved over a prolonged period of time, which can extend for 10 years or longer. As a result, the majority of the estimated liability relates to IBNR. Adjustments to our liabilities related to homes delivered in prior years are recorded in the period in which a change in our estimate occurs. The projection of losses related to these liabilities requires actuarial assumptions that are subject to variability due to uncertainties regarding construction defect claims relative to our markets and the types of product we build, insurance industry practices, and legal or regulatory actions and/or interpretations, among other factors. Key assumptions used in these estimates include claim frequencies, severities, and settlement patterns, which can occur over an extended period of time. In addition, changes in the frequency and severity of reported claims and the estimates to settle claims can impact the trends and assumptions used in the actuarial analysis, which could be material to our consolidated financial statements. Due to the degree of judgment required, and the potential for variability in these underlying assumptions, our actual future costs could differ from those estimated, and the difference could be material to our consolidated financial statements.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation We account for our stock-based compensation in accordance with ASC 718, “Compensation – Stock Compensation” (“ASC 718”). We use a lattice model for the valuation for our stock option grants. The option pricing models used are designed to estimate the value of options that, unlike employee stock options and restricted stock units, can be traded at any time and are transferable. In addition to restrictions on trading, employee stock options and restricted stock units may include other restrictions such as vesting periods. Further, such models require the input of highly subjective assumptions, including the expected volatility of the stock price. Stock-based compensation expense is generally included in “Selling, general and administrative” expense in our Consolidated Statements of Operations and Comprehensive Income.
Legal Costs, Policy [Policy Text Block]	Legal Expenses Transactional legal expenses for land acquisition and entitlement, and financing are capitalized and expensed over their appropriate life. We expense legal fees related to litigation, warranty and insurance claims when incurred.
Income Tax, Policy [Policy Text Block]	Income Taxes We account for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recorded based on temporary differences between the amounts reported for financial reporting purposes and the amounts reported for income tax purposes. In accordance with the provisions of ASC 740, we assess the realizability of our deferred tax assets. A valuation allowance must be established when, based upon available evidence, it is more likely than not that all or a portion of the deferred tax assets will not be realized. See “Income Taxes – Valuation Allowance” below. Federal and state income taxes are calculated on reported pre-tax earnings based on current tax law and also include, in the applicable period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized for financial reporting purposes in different periods than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions. We establish reserves for income taxes when, despite the belief that our tax positions are fully supportable, we believe that our positions may be challenged and disallowed by various tax authorities. The consolidated tax provisions and related accruals include the impact of such reasonably estimable disallowances as deemed appropriate. To the extent that the probable tax outcome of these matters changes, such changes in estimates will impact the income tax provision in the period in which such determination is made. ASC 740 clarifies the accounting for uncertainty in income taxes recognized and prescribes a recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. ASC 740 requires a company to recognize the financial statement effect of a tax position when it is “more-likely-than-not” (defined as a substantiated likelihood of more than 50% ), based on the technical merits of the position, that the position will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to be recognized in the financial statements based upon the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. Our inability to determine that a tax position meets the more-likely-than-not recognition threshold does not mean that the Internal Revenue Service (“IRS”) or any other taxing authority will disagree with the position that we have taken. If a tax position does not meet the more-likely-than-not recognition threshold, despite our belief that our filing position is supportable, the benefit of that tax position is not recognized in the Consolidated Statements of Operations and Comprehensive Income and we are required to accrue potential interest and penalties until the uncertainty is resolved. Potential interest and penalties are recognized as a component of the provision for income taxes. Differences between amounts taken in a tax return and amounts recognized in the financial statements are considered unrecognized tax benefits. We believe that we have a reasonable basis for each of our filing positions and intend to defend those positions if challenged by the IRS or other taxing jurisdiction. If the IRS or other taxing authorities do not disagree with our position, and after the statute of limitations expires, we will recognize the unrecognized tax benefit in the period that the uncertainty of the tax position is eliminated.
Income Taxes - Valuation Allowance [Policy Text Block]	Income Taxes — Valuation Allowance We assess the need for valuation allowances for deferred tax assets in each period based on whether it is more-likely-than-not that some portion of the deferred tax asset would not be realized. If, based on the available evidence, it is more-likely-than-not that such asset will not be realized, a valuation allowance is established against a deferred tax asset. The realization of a deferred tax asset ultimately depends on the existence of sufficient taxable income in either the carryback or carryforward periods under tax law. This assessment considers, among other matters, the nature, consistency, and magnitude of current and cumulative income and losses; forecasts of future profitability; the duration of statutory carryback or carryforward periods; our experience with operating loss and tax credit carryforwards being used before expiration; tax planning alternatives: and outlooks for the U.S. housing industry and broader economy. Changes in existing tax laws or rates could also affect our actual tax results. Due to uncertainties in the estimation process, particularly with respect to changes in facts and circumstances in future reporting periods, actual results could differ from the estimates used in our assessment that could have a material impact on our consolidated results of operations or financial position.
Geographic Segment Reporting Policy [Text Block]	Segment Reporting We operate in two segments: traditional home building and urban infill. We build and sell homes for detached and attached homes in luxury residential communities located in affluent suburban markets and cater to move-up, empty-nester, active-adult, and second-home buyers in the United States (“Traditional Home Building”). We also build and sell homes in urban infill markets through Toll Brothers City Living ® (“City Living”). We have determined that our Traditional Home Building operations operate in five geographic segments: North, Mid-Atlantic, South, West, and California. The states comprising each geographic segment are as follows: North: Connecticut, Illinois, Massachusetts, Michigan, New Jersey, and New York Mid-Atlantic: Delaware, Maryland, Pennsylvania, and Virginia South: Florida, North Carolina, and Texas West: Arizona, Colorado, Idaho, Nevada, and Washington California: California In fiscal 2018, we acquired land and commenced development activities in the Salt Lake City, Utah and Portland, Oregon markets. We expect to open communities in these markets in fiscal 2019. In fiscal 2018, we discontinued the sale of homes in Minnesota. Our operations in Minnesota were immaterial to the North geographic segment.
Related Party Transactions [Policy Text Block]	Related Party Transactions See Note 4, “Investments in Unconsolidated Entities - Rental Property Joint Ventures” for information regarding Toll Brothers Realty Trust.
Recent Accounting Pronouncements [Policy Text Block]	Recent Accounting Pronouncements In February 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”). ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act enacted on December 22, 2017 and also requires entities to disclose their accounting policy for releasing income tax effects from accumulated other comprehensive income. We elected to adopt ASU 2018-02 in the first quarter of fiscal 2018, and the adoption did not have a material effect on our consolidated financial statements and disclosures. In March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”). ASU 2017-07 requires an employer to report the service cost component of pension and other post-retirement benefit costs in the same line item as other compensation costs arising from services rendered by the pertinent employees while the other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations; such other costs are included in other income-net in our Consolidated Statements of Operations and Comprehensive Income. We adopted ASU 2017-07 on November 1, 2017, and the adoption did not have a material effect on our consolidated financial statements and disclosures. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes and forfeitures, statutory tax withholding requirements and classification on the statement of cash flows. We adopted ASU 2016-09 on November 1, 2017. Excess tax benefits or deficiencies for stock-based compensation are now reflected in our Consolidated Statements of Operations and Comprehensive Income as a component of income tax expense, whereas previously they were recognized in equity. We have also elected to account for forfeitures as they occur, rather than estimate expected forfeitures. As a result of adopting ASU 2016-09, the impact of recognizing excess tax benefits and deficiencies in our Consolidated Statements of Operations and Comprehensive Income resulted in a $4.2 million reduction in our income tax expense in our fiscal year ending October 31, 2018 . The remaining aspects of adopting ASU 2016-09 did not have a material impact on our financial statements and disclosures. In February 2017, the FASB issued ASU No. 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” (“ASU 2017-05”). ASU 2017-05 is meant to clarify the scope of the original guidance within Subtopic 610-20 that was issued in connection with ASU 2014-09, as defined below, which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also added guidance for partial sales of nonfinancial assets. ASU 2017-05 is effective for our fiscal year beginning November 1, 2018 and we are required to adopt ASU 2017-05 concurrent with the adoption of ASU 2014-09. We do not expect the adoption of ASU 2017-05 to have a material effect on our consolidated financial statements and disclosures. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which provides guidance on the classification of restricted cash in the statement of cash flows. ASU 2016-18 is effective for our fiscal year beginning November 1, 2018. We do not expect the adoption of ASU 2016-18 to have a material effect on our consolidated financial statements and disclosures. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”), which is intended to reduce diversity in practice in how certain transactions are classified and will make eight targeted changes to how cash receipts and cash payments are presented in the statement of cash flows. ASU 2016-15 is effective for our fiscal year beginning November 1, 2018. We do not expect the adoption of ASU 2016-15 to have a material effect on our consolidated financial statements and disclosures. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. ASU 2016-13 is effective for our fiscal year beginning November 1, 2020, with early adoption permitted as of November 1, 2019. We do not expect the adoption of ASU 2016-13 to have a material effect on our consolidated financial statements and disclosures. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“ASU 2016-02”), which requires an entity to recognize assets and liabilities on the balance sheet for the rights and obligations created by leased assets and provide additional disclosures. ASU 2016-02 is effective for our fiscal year beginning November 1, 2019, and, at that time, we will adopt the new standard using a modified retrospective approach and expect to apply the basket of practical expedients. We are currently evaluating the impact that the adoption of ASU 2016-02 may have on our consolidated financial statements and disclosures. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which provides guidance for revenue recognition. ASU 2014-09 affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification (“ASC”) Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 also supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under the current guidance. These judgments and estimates include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. In August 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers” (“ASU 2015-14”), which delays the effective date of ASU 2014-09 by one year. ASU 2014-09, as amended by ASU 2015-14, is effective for our fiscal year beginning November 1, 2018, and, at that time, we expect to adopt the new standard under the modified retrospective approach. We do not believe the adoption of ASU 2014-09 will have a material impact on the amount or timing of our home building revenues. However, we currently expect that the adoption of ASU 2014-09 will result in the following changes: • We currently capitalize certain costs related to our marketing efforts, including sales offices and model home upgrades and furnishings within “Inventory” on our Consolidated Balance Sheets and amortize such costs through “Selling, general, and administrative” on our Consolidated Statements of Operations and Comprehensive Income. As of November 1, 2018, we expect to reclassify approximately $105.0 million to “Property, construction, and office equipment, net” on our Consolidated Balance Sheets, primarily related to sales offices and model home improvement costs. We plan to continue depreciating these assets through “Selling, general, and administrative” on our Consolidated Statements of Operations and Comprehensive Income. Additionally, we expect to record a cumulative effect adjustment to retained earnings of approximately $18.0 million for certain other marketing costs that will no longer qualify for capitalization under the new guidance, and such costs will be expensed as incurred in the future. • We currently record our land sale activities, net of their related expenses, within “Other income - net” on our Consolidated Statements of Operations and Comprehensive Income. Beginning November 1, 2018, we expect to include this activity in income from operations and breakout the components of land sale revenues and land sale cost of sales on our Consolidated Statements of Operations and Comprehensive Income. In addition, due to the existence of certain repurchase options within our existing agreements to sell lots to third party builders in our master planned communities, both for wholly-owned projects as well as projects in which we are party to a joint venture, we expect to record a cumulative effect adjustment to retained earnings of approximately $11.0 million to account for previously settled lots for which the related repurchase option has not yet expired. The revenue and related expenses for such lots will be recognized in future periods when such repurchase options expire. • Retained customer deposits are currently classified in “Other income-net” on our Consolidated Statements of Operations and Comprehensive Income. As of November 1, 2018, we expect these retained customer deposits will be included in “Revenue” on our Consolidated Statements of Operations and Comprehensive Income. Prior period balances for retained customer deposits will not be reclassified and are not material to our consolidated financial statements. We additionally expect our accounting for incomplete deliverables at the time a home closes will be impacted upon adoption of the new guidance and continue to refine our analysis which quantifies the impact of such change. However, we do not expect the impact of incomplete deliverables to have a material effect on our consolidated financial statements and disclosures.
Reclassification, Policy [Policy Text Block]	Reclassification Certain prior period amounts have been reclassified to conform to the fiscal 2018 presentation. Such reclassifications primarily relate to the (i) reclassification of “Restricted cash” into “Receivables, prepaid expenses, and other assets” on the Consolidated Balance Sheets and Consolidated Statements of Cash Flows; (ii) reclassification of certain pension costs from “Selling, general and administrative” to “Other income – net” on the Consolidated Statements of Operations and Comprehensive Income as a result of the adoption of ASU 2017-07; and (iii) removal of the activity related to excess tax benefits from stock-based compensation on the Consolidated Statements of Cash Flows as a result of the adoption of ASU 2016-09.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Stock-Based Benefit Plans We grant stock options, restricted stock, and various types of restricted stock units to our employees and our nonemployee directors under our stock incentive plans. We have two active stock incentive plans, one for employees (including officers) and one for nonemployee directors. Our active stock incentive plans provide for the granting of incentive stock options (solely to employees) and nonqualified stock options with a term of up to 10 years at a price not less than the market price of the stock at the date of grant. Our active stock incentive plans also provide for the issuance of stock appreciation rights and restricted and unrestricted stock awards and stock units, which may be performance-based. At October 31, 2018 , 2017 , and 2016 , we had 5.1 million ; 5.8 million ; and 6.8 million shares, respectively, available for grant under our stock incentive plans. We have two additional stock incentive plans for employees, officers, and directors that are inactive except for outstanding stock option awards at October 31, 2018 . No additional equity awards may be granted under these plans. Stock options granted under these plans were made with a term of up to 10 years at a price not less than the market price of the stock at the date of grant and generally vested over a four-year period for employees and a two-year period for nonemployee directors. The following table provides information regarding the amount of total stock-based compensation expense recognized by us for fiscal 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 Total stock-based compensation expense recognized $ 28,312 $ 28,466 $ 26,679 Income tax benefit recognized $ 7,902 $ 11,125 $ 10,450 At October 31, 2018 , 2017 , and 2016 , the aggregate unamortized value of outstanding stock-based compensation awards was approximately $20.9 million , $24.2 million , and $27.0 million , respectively. Information about our more significant stock-based compensation programs is outlined below. Stock Options: Stock options granted to employees generally vest over a four-year period, although certain grants may vest over a longer or shorter period. Stock options granted to nonemployee directors generally vest over a two-year period. Shares issued upon the exercise of a stock option are either from shares held in treasury or newly issued shares. The fair value of each option award is estimated on the date of grant using a lattice-based option valuation model that uses ranges of assumptions noted in the following table. Expected volatilities were based on implied volatilities from traded options on our stock, historical volatility of our stock, and other factors. The expected lives of options granted were derived from the historical exercise patterns and anticipated future patterns and represent the period of time that options granted are expected to be outstanding; the range given below results from certain groups of employees exhibiting different behaviors. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The following table summarizes the weighted-average assumptions and fair value used for stock option grants in each of the fiscal years ended October 31, 2018 , 2017 , and 2016 : 2018 2017 2016 Expected volatility 27.66% - 31.83% 29.93% - 41.05% 32.03% - 42.31% Weighted-average volatility 30.33% 34.72% 34.69% Risk-free interest rate 2.17% - 2.35% 1.96% - 2.52% 1.58% - 2.14% Expected life (years) 5.00 - 8.50 4.60 - 9.24 4.56 - 9.17 Dividends 0.67% none none Weighted-average fair value per share of options granted $16.09 $12.16 $11.24 The fair value of stock option grants is recognized evenly over the vesting period of the options or over the period between the grant date and the time the option becomes nonforfeitable by the employee, whichever is shorter. Information regarding the stock compensation expense related to stock options for fiscal 2018 , 2017 and 2016 was as follows (amounts in thousands): 2018 2017 2016 Stock compensation expense recognized - options $ 7,497 $ 10,337 $ 10,986 At October 31, 2018 , total compensation cost related to nonvested stock option awards not yet recognized was approximately $6.5 million , and the weighted-average period over which we expect to recognize such compensation costs was approximately 1.5 years . The following table summarizes stock option activity for our plans during each of the fiscal years ended October 31, 2018 , 2017 , and 2016 (amounts in thousands, except per share amounts): 2018 2017 2016 Number of options Weighted- average exercise price Number of options Weighted- average exercise price Number of options Weighted- average exercise price Balance, beginning 6,120 $ 27.60 8,514 $ 26.36 8,025 $ 25.75 Granted 210 47.84 595 31.61 965 32.85 Exercised (797 ) 24.16 (2,863 ) 24.54 (255 ) 24.04 Canceled (30 ) 33.08 (126 ) 32.10 (221 ) 35.23 Balance, ending 5,503 $ 28.84 6,120 $ 27.60 8,514 $ 26.36 Options exercisable, at October 31, 4,231 $ 27.03 4,266 $ 25.42 6,407 $ 24.14 The weighted average remaining contractual life (in years) for options outstanding and exercisable at October 31, 2018 , was 4.8 and 4.0 , respectively. The intrinsic value of options outstanding and exercisable is the difference between the fair market value of our common stock on the applicable date (“Measurement Value”) and the exercise price of those options that had an exercise price that was less than the Measurement Value. The intrinsic value of options exercised is the difference between the fair market value of our common stock on the date of exercise and the exercise price. The following table provides information pertaining to the intrinsic value of options outstanding and exercisable at October 31, 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 Intrinsic value of options outstanding $ 30,477 $ 112,886 $ 31,852 Intrinsic value of options exercisable $ 29,010 $ 87,978 $ 31,852 Information pertaining to the intrinsic value of options exercised and the fair market value of options that became vested or modified in each of the fiscal years ended October 31, 2018 , 2017 , and 2016 , is provided below (amounts in thousands): 2018 2017 2016 Intrinsic value of options exercised $ 18,165 $ 32,951 $ 2,337 Fair market value of options vested $ 10,007 $ 10,897 $ 9,690 Our stock option plans permit optionees to exercise stock options using a “net exercise” method at the discretion of the Executive Compensation Committee of the Board of Directors (“Executive Compensation Committee”). In a net exercise, we withhold from the total number of shares that otherwise would be issued to an optionee upon exercise of the stock option that number of shares having a fair market value at the time of exercise equal to the option exercise price and applicable minimum income tax withholdings and remit the remaining shares to the optionee. In fiscal 2018, the net exercise method was not utilized to exercise options. The following table provides information regarding the use of the net exercise method for fiscal 2017 and 2016 : 2017 2016 Options exercised 15,000 5,000 Shares withheld 14,472 3,547 Shares issued 528 1,453 Average fair market value per share withheld $ 32.98 $ 32.85 Aggregate fair market value of shares withheld (in thousands) $ 477 $ 117 Performance-Based Restricted Stock Units: In fiscal 2018 , 2017 , and 2016 , the Executive Compensation Committee approved awards of performance-based restricted stock units (“Performance-Based RSUs”) relating to shares of our common stock to certain members of our senior management. The number of shares earned for Performance-Based RSUs are based on the attainment of certain performance metrics approved by the Executive Compensation Committee in the year of grant. The number of shares underlying the Performance-Based RSUs that may be issued to the recipients ranges from 0% to 110% of the base award depending on actual achievement as compared to the target performance goals. Shares earned based on actual performance generally vest pro-rata over a four-year period provided the recipients continue to be employed by us as specified in the award document. The value of the Performance-Based RSUs was determined to be equal to the estimated number of shares of our common stock to be issued multiplied by the closing price of our common stock on the New York Stock Exchange (“NYSE”) on the date the Performance-Based RSU awards were approved by the Executive Compensation Committee (“Valuation Date”). We evaluate the performance goals quarterly and estimate the number of shares underlying the Performance-Based RSUs that are probable of being issued. The following table provides information regarding the issuance, valuation assumptions, and amortization of the Performance-Based RSUs issued in fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Number of shares underlying Performance-Based RSUs to be issued 135,554 168,417 182,854 Aggregate number of Performance-Based RSUs outstanding at October 31 786,857 940,117 1,074,222 Closing price of our common stock on Valuation Date $ 47.84 $ 31.61 $ 32.85 Aggregate grant date fair value of Performance-Based RSUs issued (in thousands) $ 6,485 $ 5,324 $ 6,007 Performance-Based RSU expense recognized (in thousands) $ 6,949 $ 7,031 $ 8,301 Unamortized value of Performance-Based RSUs at October 31 (in thousands) $ 3,824 $ 4,599 $ 6,556 Shares earned with respect to Performance-Based RSUs issued in December 2011, 2012, and 2013 were delivered in fiscal 2016, 2017, and 2018, respectively. The recipients of these Performance-Based RSUs elected to use a portion of the shares underlying the Performance-Based RSUs to pay the required income withholding taxes on the payout. In fiscal 2018, the gross value of the payout was $13.7 million ( 288,814 shares), the minimum income tax withholding was $6.0 million ( 126,330 shares) and the net value of the shares delivered was $7.7 million ( 162,484 shares). In fiscal 2017, the gross value of the payout was $9.6 million ( 302,514 shares), the minimum income tax withholding was $4.2 million ( 133,098 shares) and the net value of the shares delivered was $5.4 million ( 169,416 shares). In fiscal 2016, the gross value of the payout was $12.2 million ( 370,171 shares), the minimum income tax withholding was $5.4 million ( 164,090 shares) and the net value of the shares delivered was $6.8 million ( 206,081 shares). Total Shareholder Return Restricted Stock Units: In fiscal 2018 , 2017 , and 2016 , the Executive Compensation Committee approved awards of relative total shareholder return performance-based restricted stock units (“TSR RSUs”) relating to 39,411 , 46,361 and 171,705 target shares, respectively, of our common stock to certain members of our senior management. Shares underlying the TSR RSUs granted are earned by comparing our total shareholder return during specified performance periods to the total shareholder returns of companies in a performance peer group as defined in the award document. The specified performance periods are as follows: Performance Period Target Number of TSR RSUs issued Fiscal 2018 November 1, 2017 to October 31, 2020 39,411 Fiscal 2017 November 1, 2016 to October 31, 2019 46,361 Fiscal 2016 Tranche 1 (one-year) November 1, 2015 to October 31, 2016 61,796 Tranche 2 (two-year) November 1, 2015 to October 31, 2017 57,230 Tranche 3 (three-year) November 1, 2015 to October 31, 2018 52,679 The TSR RSUs generally vest at the end of a three -year period provided the recipients continue to be employed by us as specified in the award document. Based upon our ranking in the performance peer group, the recipient of the TSR RSUs may earn a total award ranging from 0% to 200% of the target number of TSR RSUs granted. In fiscal 2018, recipients of Tranche 3 TSR RSUs earned 76.81% of the target based upon our total shareholder return ranking in the performance peer group during the three-year period ended October 31, 2018. In fiscal 2017, recipients of Tranche 2 TSR RSUs earned 83.05% of the target based upon our total shareholder return ranking in the performance peer group during the two-year period ended October 31, 2017. In fiscal 2016, recipients of Tranche 1 TSR RSUs earned 0% of the target based upon our total shareholder return ranking in the performance peer group during the one-year period ended October 31, 2016. We estimated the fair value of the TSR RSUs at the grant date using a Monte Carlo simulation. The following table summarizes the assumptions used in the Monte Carlo simulation and the fair value per share of the TSR RSUs granted in fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Weighted-average volatility 26.58% 26.91% 28.66% Risk-free interest rate 1.92% 1.52% 1.23% Dividends none none none Weighted-average fair value per share of TSR RSUs $52.62 $39.21 $41.16 The length of each performance period was used as the expected term in the simulation for each respective tranche. The following table provides information on expense recognized and the unamortized value of our TSR RSUs for fiscal 2018 , 2017 , and 2016 (amounts in thousands): 2018 2017 2016 TSR RSUs expense recognized $ 2,502 $ 3,400 $ 3,300 Unamortized value of TSR RSUs at October 31 $ 1,773 $ 2,200 $ 3,800 Time-Based Restricted Stock Units: In fiscal 2018 , 2017 , and 2016 , we issued time-based restricted stock units (“RSUs”) to various officers, employees, and nonemployee directors. These RSUs generally vest in annual installments over a two- to four-year period. The value of the RSUs was determined to be equal to the number of shares of our common stock underlying the RSUs multiplied by the closing price of our common stock on the NYSE on the date the RSUs were awarded. The following table provides information regarding these RSUs for fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Time-Based RSUs issued: Number of RSUs issued 296,790 377,564 139,684 Weighted average closing price per share of our common stock on date of issuance $ 47.84 $ 31.61 $ 32.85 Aggregate fair value of RSUs issued (in thousands) $ 14,198 $ 11,935 $ 4,589 Time-Based RSU expense recognized (in thousands): $ 11,193 $ 7,572 $ 3,958 2018 2017 2016 At October 31: Aggregate number of Time-Based RSUs outstanding 850,853 673,224 396,716 Cumulative unamortized value of Time-Based RSUs (in thousands) $ 8,818 $ 6,783 $ 2,956 Our stock incentive plans permit us to withhold from the total number of shares that otherwise would be issued to a restricted stock unit recipient upon distribution that number of shares having a fair value at the time of distribution equal to the applicable income tax withholdings due and remit the remaining shares to the restricted stock unit recipient. The following table provides information regarding the number of shares withheld, the income tax withholding due, and the remaining shares issued to the recipients for fiscal 2018 , 2017 , and 2016 : 2018 2017 2016 Number of shares withheld 23,289 20,400 25,340 Income tax withholdings due $ 1,145 $ 664,300 $ 827,800 Remaining shares issued to the recipients 58,552 52,757 70,627 Employee Stock Purchase Plan Our employee stock purchase plan enables substantially all employees to purchase our common stock at 95% of the market price of the stock on specified offering dates without restriction or at 85% of the market price of the stock on specified offering dates subject to restrictions. The plan, which terminates in December 2027, provides that 500,000 shares be reserved for purchase. At October 31, 2018 , 448,000 shares were available for issuance.

On one of these transactions, we recognized a gain of $1.0 million in fiscal 2018.

We will recognize the deferred gain into income as the guarantees provided expire. Land sale revenues for the year ended October 31, 2017 included $257.8 million related to sale transactions with two new Home Building Joint Ventures and a Rental Property Joint Venture in which we have interests ranging from 20% to 25% .

We recognized the gain as units were sold to the ultimate home buyers which is included in deferred gains recognized above. In the fourth quarter of fiscal 2017, we purchased the remaining inventory from this Home Building Joint Venture. The remaining unamortized deferred gain was used to reduce the basis of the inventory acquired. See Note 4, “Investments in Unconsolidated Entities,” for more information on these transactions. Subsequent event In December 2018, we sold one of our golf club properties to a third party for $18.5 million .
