Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and include the accounts of D.R. Horton, Inc. and all of its wholly-owned, majority-owned and controlled subsidiaries, which are collectively referred to as the Company, unless the context otherwise requires. Noncontrolling interests represent the proportionate equity interests in consolidated entities that are not 100% owned by the Company. As of September 30, 2022, the Company owns a 63% controlling interest in Forestar Group Inc. (Forestar) and therefore is required to consolidate 100% of Forestar within its consolidated financial statements, and the 37% interest the Company does not own is accounted for as noncontrolling interests. All intercompany accounts, transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Revenue Recognition Homebuilding revenue and related profit are generally recognized at the time of the closing of a sale, when title to and possession of the property are transferred to the buyer. The Company’s performance obligation, to deliver the agreed-upon home, is generally satisfied in less than one year from the original contract date. Proceeds from home closings held for the Company’s benefit at title companies are included in homebuilding cash and cash equivalents in the consolidated balance sheets. When the Company executes sales contracts with its homebuyers, or when it requires advance payment from homebuyers for custom changes, upgrades or options related to their homes, the cash deposits received are recorded as liabilities until the homes are closed or the contracts are cancelled. The Company either retains or refunds to the homebuyer deposits on cancelled sales contracts, depending upon the applicable provisions of the contract or other circumstances. Forestar’s land and lot sales revenue and related profit are generally recognized at the time of the closing of a sale, when title to and possession of the property are transferred to a third-party buyer. Forestar’s revenues from land and lot sales to D.R. Horton are eliminated in the consolidated financial statements. The Company rarely purchases unimproved land for resale, but periodically may elect to sell parcels of land that do not fit into its strategic operating plans. Revenue from land sales is typically recognized on the closing date, which is generally when performance obligations are satisfied. The Company’s rental operations develop, construct, lease and sell residential multi-family and single-family rental properties. Revenue is recognized from the sale of these properties on the closing date, which is when performance obligations are satisfied. Rental income from these properties is recognized as other income. Financial services revenues associated with the Company’s title operations are recognized as closing services are rendered and title insurance policies are issued, both of which generally occur simultaneously as each home is closed. Revenues associated with the Company’s mortgage operations primarily include net gains on the sale of mortgage loans and servicing rights. The Company typically elects the fair value option for its mortgage loan originations whereby mortgage loans held for sale are recorded at fair value based on either sale commitments or current market quotes and loan values are adjusted through revenues for subsequent changes in fair value until the loans are sold. Expected gains and losses from the sale of servicing rights are included in the measurement of all written loan commitments that are accounted for at fair value through revenues at the time of commitment. The Company sells substantially all of the mortgages it originates and the related servicing rights to third-party purchasers. Interest income is earned from the date a mortgage loan is originated until the loan is sold. Cash and Cash Equivalents The Company considers all highly liquid investments with an initial maturity of three months or less when purchased to be cash equivalents. Proceeds from home closings held for the Company’s benefit at title companies, which totaled $494.8 million and $478.9 million at September 30, 2022 and 2021, respectively, are included in homebuilding cash and cash equivalents in the consolidated balance sheets. Cash balances of the Company’s captive insurance subsidiary, which are expected to be used to fund the subsidiary’s operations and pay future anticipated legal claims, were $64.4 million and $55.9 million at September 30, 2022 and 2021, respectively, and are included in cash and cash equivalents in the consolidated balance sheets. Restricted Cash The Company has cash that is restricted as to its use. Restricted cash related to homebuilding and land development operations includes customer deposits that are temporarily restricted in accordance with regulatory requirements. Restricted cash related to financial services is mortgagor related funds held by the Company for taxes and insurance on an interim basis until the loans are sold. Inventories and Cost of Sales Inventory includes the costs of direct land acquisition, land development and construction, capitalized interest, real estate taxes and direct overhead costs incurred during development and construction. Costs incurred after projects or homes are substantially complete, such as utilities, maintenance, and cleaning, are charged to selling, general and administrative (SG&A) expense as incurred. All indirect overhead costs, such as compensation of sales personnel, division and region management, and the costs of advertising and builder’s risk insurance are charged to SG&A expense as incurred. Land and development costs are typically allocated to individual residential lots on a pro-rata basis, and the costs of residential lots are transferred to construction in progress when home construction begins. Home construction costs are specifically identified and recorded to individual homes. Cost of sales for homes closed includes the specific construction costs of each home and all applicable land acquisition, land development and related costs (both incurred and estimated to be incurred) allocated to each residential lot based upon the total number of homes expected to be closed in each community. Cost of sales for lots sold includes all applicable land acquisition, land development and related costs (both incurred and estimated to be incurred) allocated to each residential lot in the community. Any changes to the estimated total development costs subsequent to the initial home or lot closings in a community are generally allocated on a pro-rata basis to the remaining homes or lots in the community associated with the relevant development activity. Development and construction costs incurred related to the rental operations are recorded as rental property inventory. Cost of sales related to the rental operations include the specific construction costs and all applicable land acquisition, land development and related costs for each rental project. When a home is closed, the Company generally has not paid all incurred costs necessary to complete the home. A liability and a corresponding charge to cost of sales are recorded for the amount estimated to ultimately be paid related to completed homes that have been closed. Home construction budgets are compared to actual recorded costs to determine the additional costs remaining to be paid on each closed home. The Company rarely purchases land for resale. However, when the Company owns land or communities under development that do not fit into its development and construction plans, and the Company determines that it will sell the asset, the project is accounted for as land held for sale if certain criteria are met. The Company records land held for sale at the lesser of its carrying value or fair value less estimated costs to sell. At the end of each quarter, the Company reviews the performance and outlook for all of its communities and land inventories for indicators of potential impairment. If indicators of impairment are present for a community, the Company performs an impairment evaluation of the community, which includes an analysis to determine if the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts. The Company’s estimate of undiscounted cash flows from communities analyzed may change and could result in a future need to record impairment charges to adjust the carrying value of these assets to their estimated fair value. There are several factors which could lead to changes in the estimates of undiscounted future cash flows for a given community. The most significant of these includes pricing and incentive levels actually realized by the community, the rate at which the homes are sold and the costs incurred to develop the lots and construct the homes. Pricing and incentive levels are often interrelated with sales pace in a community, such that a price reduction is typically expected to increase the sales pace. Further, both of these factors are heavily influenced by the competitive pressures facing a given community from both new and existing homes. If conditions in the broader economy, homebuilding industry or specific markets in which the Company operates worsen, and as the Company evaluates specific community pricing and incentives, construction and development plans, and its overall land sale strategies, it may be required to evaluate additional communities for potential impairment. This may result in impairment charges which could be significant. When events or circumstances indicate that the carrying values on finished homes in substantially completed communities and completed rental properties are greater than the fair values less estimated costs to sell these homes, impairment charges are also recorded. The key assumptions relating to inventory valuations are impacted by local market and economic conditions and are inherently uncertain. Due to uncertainties in the estimation process, actual results could differ from such estimates. See Note C. Capitalized Interest The Company capitalizes interest costs incurred to inventory during active development and construction (active inventory). Capitalized interest is charged to cost of sales as the related inventory is delivered to the buyer. During periods in which the Company’s active inventory is lower than its debt level, a portion of the interest incurred is reflected as interest expense in the period incurred. During fiscal 2022, 2021 and 2020, the Company’s active inventory exceeded its debt level, and all interest incurred was capitalized to inventory. See Note E. Land and Lot Purchase Contracts The Company enters into land and lot purchase contracts to acquire land or lots for the construction of homes. Under these contracts, the Company will fund a stated deposit in consideration for the right, but not the obligation, to purchase land or lots at a future point in time with predetermined terms. Under the terms of many of the purchase contracts, the deposits are not refundable in the event the Company elects to terminate the contract. Land purchase contract deposits and capitalized pre-acquisition costs are expensed to cost of sales when the Company believes it is probable that it will not acquire the property under contract and will not be able to recover these costs through other means. See Notes C and L. Variable Interests Land purchase contracts can result in the creation of a variable interest in the entity holding the land parcel under contract. There was one variable interest entity consolidated for $64.3 million in the Company’s balance sheet at September 30, 2022 because the Company determined it controlled the activities that most significantly impacted the variable interest entity’s economic performance. There were no variable interest entities consolidated in the Company’s balance sheet at September 30, 2021. The maximum exposure to losses related to the Company’s unconsolidated variable interest entities is limited to the amounts of the Company’s related deposits. At September 30, 2022 and 2021, the deposits related to these contracts totaled $1.5 billion and $870.2 million, respectively, and are included in other assets in the consolidated balance sheets. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Repairs and maintenance costs are expensed as incurred. Depreciation generally is recorded using the straight-line method over the estimated useful life of the asset. The depreciable life of model home furniture is 2 years, depreciable lives of other furniture and equipment typically range from 2 to 5 years, and depreciable lives of buildings and improvements typically range from 5 to 30 years. See Note F. Business Acquisitions The Company accounts for acquisitions of businesses by allocating the purchase price of the business to the various assets acquired and liabilities assumed at their respective fair values. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill. Significant judgment is often required in estimating the fair value of assets acquired, particularly intangible assets. These estimates and assumptions are based on historical experience, information obtained from the management of the acquired companies and the Company’s estimates of significant assumptions that a market participant would use when determining fair value. While the Company believes the estimates and assumptions are reasonable, they are inherently uncertain. Unanticipated market or macroeconomic events and circumstances may occur, which could affect the accuracy or validity of the estimates and assumptions. In April 2022, the Company and Vidler Water Resources, Inc. (Vidler) entered into a definitive merger agreement pursuant to which the Company would acquire all of the outstanding shares of Vidler for $15.75 per share in an all-cash transaction. Under the terms of the merger agreement, in May 2022, the Company completed a tender offer and acquired all of the outstanding shares for a total purchase price of $290.5 million. There was no goodwill recorded as a result of this transaction. The Company’s allocation of the purchase price to the assets, liabilities and noncontrolling interest acquired is as follows (in millions): Cash and cash equivalents $ 19.0 Deferred income taxes, net of valuation allowance of $15.8 million 14.8 Water rights and other water-related assets (1) 280.1 Total assets 313.9 Other liabilities 5.4 Total liabilities 5.4 Noncontrolling interest 18.0 Net assets acquired $ 290.5 _____________________________________ (1) Water rights and other water-related assets were measured at fair value using Level 3 inputs and are included in other assets in the Company’s consolidated financial statements. Goodwill The Company records goodwill associated with its acquisitions of businesses when the purchase price of the business exceeds the fair value of the identifiable net assets acquired. Goodwill balances are evaluated for potential impairment on at least an annual basis by performing a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of an operating segment with goodwill is less than its carrying amount. If the qualitative assessment indicates that additional impairment testing is required, then a quantitative assessment is performed to determine the operating segment’s fair value. The estimated fair value is determined by discounting the future cash flows of the operating segment to present value. If the carrying value of the operating segment exceeds its fair value, the Company records a goodwill impairment by the amount that an operating segment’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. As a result of the qualitative assessments performed in fiscal 2022, 2021 and 2020, no impairment charges were indicated or recorded. The Company’s goodwill balances by reporting segment were as follows: September 30, 2022 2021 (In millions) Northwest $ 2.2 $ 2.2 Southwest — — South Central 15.9 15.9 Southeast 6.0 6.0 East 60.5 60.5 North 49.7 49.7 Forestar 29.2 29.2 Total goodwill $ 163.5 $ 163.5 Warranty Claims The Company provides its homebuyers with a ten-year limited warranty for major defects in structural elements such as framing components and foundation systems, a two-year limited warranty on major mechanical systems and a one-year limited warranty on other construction components. Since the Company subcontracts its construction work to subcontractors who typically provide it with an indemnity and a certificate of insurance prior to receiving payments for their work, claims relating to workmanship and materials are generally the primary responsibility of the subcontractors. Warranty liabilities have been established by charging cost of sales for each home delivered. The amounts charged are based on management’s estimate of the warranty-related costs expected to be incurred in the future. The Company’s warranty liability is based upon historical warranty cost experience in each market in which it operates and is adjusted to reflect qualitative risks associated with the types of homes built and the geographic areas in which they are built. See Note L. Legal Claims and Insurance The Company records expenses and liabilities for legal claims related to construction defect matters, personal injury claims, employment matters, land development issues, contract disputes and other matters. The amounts recorded for these contingencies are based on the estimated costs of pending claims and the estimated costs of anticipated future claims related to previously closed homes. The Company estimates and records receivables under its applicable insurance policies for these legal claims when recovery is probable. However, because the self-insured retentions under these policies are significant, the Company anticipates it will largely be self-insured. Additionally, the Company may have the ability to recover a portion of its losses from its subcontractors and their insurance carriers when the Company has been named as an additional insured on their insurance policies. See Note L. Advertising Costs The Company expenses advertising costs as incurred. Advertising expense was approximately $41.7 million, $36.1 million and $41.7 million in fiscal 2022, 2021 and 2020, respectively. Income Taxes The Company’s income tax expense is calculated using the asset and liability method, under which deferred tax assets and liabilities are recognized based on the future tax consequences attributable to temporary differences between the financial statement amounts of assets and liabilities and their respective tax bases and attributable to net operating losses and tax credit carryforwards. When assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. The realization of deferred tax assets is dependent upon the generation of sufficient taxable income in future periods and in the jurisdictions in which those temporary differences become deductible. The Company records a valuation allowance when it determines it is more likely than not that a portion of the deferred tax assets will not be realized. The accounting for deferred taxes is based upon estimates of future results. Differences between the anticipated and actual outcomes of these future results could have a material impact on the Company’s consolidated results of operations or financial position. Also, changes in existing federal and state tax laws and tax rates could affect future tax results and the valuation of the Company’s deferred tax assets and liabilities. See Note H. Interest and penalties related to unrecognized tax benefits are recognized in the financial statements as a component of income tax expense. Significant judgment is required to evaluate uncertain tax positions. The Company evaluates its uncertain tax positions on a quarterly basis. The evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in increases or decreases in the Company’s income tax expense in the period in which the change is made. The Company’s unrecognized tax benefits totaled $2.9 million at both September 30, 2022 and 2021. Earnings Per Share Basic earnings per share is based on the weighted average number of shares of common stock outstanding during each year. Diluted earnings per share is based on the weighted average number of shares of common stock and dilutive securities outstanding during each year. See Note I. Stock-Based Compensation The Company’s stockholders formally authorize shares of its common stock to be available for future grants of stock-based compensation awards. From time to time, the Compensation Committee of the Company’s Board of Directors authorizes the grant of stock-based compensation to its employees and directors from these available shares. At September 30, 2022, the outstanding stock-based compensation awards include stock options and restricted stock units. Grants of restricted stock units vest over a certain number of years as determined by the Compensation Committee of the Board of Directors. Restricted stock units outstanding at September 30, 2022 have a remaining vesting period up to 4.5 years. Stock options are granted at exercise prices which equal the market value of the Company’s common stock at the date of the grant. All stock options outstanding at September 30, 2022 have vested and expire 10 years after the dates on which they were granted. The compensation expense for stock-based awards is based on the fair value of the award and is recognized on a straight-line basis over the remaining vesting period. The fair values of restricted stock units are based on the Company’s stock price on the date of grant. The fair values of stock options granted are calculated on the date of grant using a Black-Scholes option pricing model. Determining the fair value of stock options requires judgment in developing assumptions and involves a number of estimates. These estimates include, but are not limited to, the expected stock price volatility over the term of the awards, the expected dividend yield and expected stock option exercise behavior. See Note K. Fair Value Measurements The Financial Accounting Standards Board’s (FASB) authoritative guidance for fair value measurements establishes a three-level hierarchy based upon the inputs to the valuation model of an asset or liability. When available, the Company uses quoted market prices in active markets to determine fair value. The Company considers the principal market and nonperformance risk associated with the Company’s counterparties when determining the fair value measurements, if applicable. Fair value measurements are used for the Company’s mortgage loans held for sale, mortgage servicing rights, interest rate lock commitments and other derivative instruments on a recurring basis and are used for inventories, other mortgage loans, rental properties and real estate owned on a nonrecurring basis, when events and circumstances indicate that the carrying value is not recoverable. See Note N. Pending Accounting Standards In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform,” which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (LIBOR) or by another reference rate expected to be discontinued. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform - Scope,” which clarified the scope and application of the original guidance. The Company will adopt these standards when LIBOR is discontinued and does not expect them to have a material impact on its consolidated financial statements or related disclosures. In October 2021, the FASB issued ASU 2021-08, which requires application of ASC 606, “Revenue from Contracts with Customers,” to recognize and measure contract assets and liabilities from contracts with customers acquired in a business combination. ASU 2021-08 creates an exception to the general recognition and measurement principle in ASC 805 and will result in recognition of contract assets and contract liabilities consistent with those recorded by the acquiree immediately before the acquisition date. The guidance is effective for the Company beginning October 1, 2023, with early adoption permitted. The Company is currently evaluating the impact of this guidance, and it is not expected to have a material impact on its consolidated financial position, results of operations or cash flows.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION The Company’s operating segments are its 78 homebuilding divisions, its majority-owned Forestar residential lot development operations, its financial services operations, its rental operations and its other business activities. The Company’s reporting segments are its homebuilding reporting segments, its Forestar lot development segment, its financial services segment and its rental operations segment. Homebuilding The homebuilding operating segments are aggregated into six reporting segments. The reporting segments and the states in which the Company has homebuilding operations are as follows: Northwest: Colorado, Oregon, Utah and Washington Southwest: Arizona, California, Hawaii, Nevada and New Mexico South Central: Arkansas, Oklahoma and Texas Southeast: Alabama, Florida, Louisiana and Mississippi East: Georgia, North Carolina, South Carolina and Tennessee North: Delaware, Illinois, Indiana, Iowa, Kentucky, Maryland, Minnesota, Nebraska, Homebuilding is the Company’s core business, generating 95%, 96% and 97% of consolidated revenues in fiscal 2022, 2021 and 2020, respectively. The Company’s homebuilding divisions are primarily engaged in the acquisition and development of land and the construction and sale of residential homes, with operations in 106 markets across 33 states. Most of the revenue generated by the Company’s homebuilding operations is from the sale of completed homes and to a lesser extent from the sale of land and lots. Forestar The Forestar segment is a residential lot development company with operations in 53 markets across 21 states. The Company’s homebuilding divisions acquire finished lots from Forestar in accordance with the master supply agreement between the two companies. Forestar’s segment results are presented on their historical cost basis, consistent with the manner in which management evaluates segment performance. Financial Services The Company’s financial services segment provides mortgage financing and title agency services to homebuyers in many of the Company’s homebuilding markets. The segment generates the substantial majority of its revenues from originating and selling mortgages and collecting fees for title insurance agency and closing services. The Company sells substantially all of the mortgages it originates and the related servicing rights to third-party purchasers. Rental The Company’s rental segment consists of multi-family and single-family rental operations. The multi-family rental operations develop, construct, lease and sell residential rental properties. The single-family rental operations primarily construct and lease single-family homes within a community and then market each community for a bulk sale of rental homes. Other In addition to its homebuilding, Forestar, financial services and rental operations, the Company engages in other business activities through its subsidiaries. The Company conducts insurance-related operations, owns water rights and other water-related assets, owns non-residential real estate including ranch land and improvements and owns and operates energy-related assets. The results of these operations are immaterial for separate reporting and therefore are grouped together and presented in the Eliminations and Other column in the tables that follow. The accounting policies of the reporting segments are described throughout Note A.

Inventory Impairments and Land Option Cost Write-Offs [Abstract]
Inventory	INVENTORIES At the end of each quarter, the Company reviews the performance and outlook for all of its communities and land inventories for indicators of potential impairment and performs detailed impairment evaluations and analyses when necessary. As of September 30, 2022, the Company determined that no communities were impaired, and no impairment charges were recorded during the three months ended September 30, 2022. There were $3.8 million of impairment charges recorded during fiscal 2022 that related to a Forestar land development project, compared to $5.6 million and $1.7 million of impairment charges recorded in fiscal 2021 and 2020, respectively. During fiscal 2022, 2021 and 2020, earnest money and pre-acquisition cost write-offs related to land purchase contracts that the Company has terminated or expects to terminate were $66.6 million, $23.0 million and $22.1 million, respectively. Inventory impairments and land option charges are included in cost of sales in the consolidated statements of operations.

Homebuilding The Company has a $2.19 billion senior unsecured homebuilding revolving credit facility with an uncommitted accordion feature that could increase the size of the facility to $3.0 billion, subject to certain conditions and availability of additional bank commitments. The facility also provides for the issuance of letters of credit with a sublimit equal to 100% of the total revolving credit commitments. Letters of credit issued under the facility reduce the available borrowing capacity. Borrowings and repayments under the facility totaled $3.45 billion each during fiscal 2022. At September 30, 2022, there were no borrowings outstanding and $220 million of letters of credit issued under the revolving credit facility, resulting in available capacity of $1.97 billion. In October 2022, the Company’s senior unsecured homebuilding revolving credit facility was amended to extend its maturity date to October 28, 2027. The Company’s homebuilding revolving credit facility imposes restrictions on its operations and activities, including requiring the maintenance of a maximum allowable leverage ratio and a borrowing base restriction if the leverage ratio exceeds a certain level. These covenants are measured as defined in the credit agreement governing the facility and are reported to the lenders quarterly. A failure to comply with these financial covenants could allow the lending banks to terminate the availability of funds under the revolving credit facility or cause any outstanding borrowings to become due and payable prior to maturity. The credit agreement governing the facility and the indentures governing the senior notes also impose restrictions on the creation of secured debt and liens. At September 30, 2022, the Company was in compliance with all of the covenants, limitations and restrictions of its homebuilding revolving credit facility and public debt obligations. D.R. Horton has an automatically effective universal shelf registration statement filed with the SEC in July 2021, registering debt and equity securities that the Company may issue from time to time in amounts to be determined. In September 2022, the Company repaid $350 million principal amount of its 4.375% senior notes at maturity. The key terms of the Company’s homebuilding senior notes outstanding as of September 30, 2022 are summarized below. Notes Payable Principal Amount Date Issued Date Due Redeemable Effective (In millions) 4.75% senior notes $300 February 2013 February 15, 2023 Yes 4.9% 5.75% senior notes $400 August 2013 August 15, 2023 Yes 5.9% 2.5% senior notes $500 October 2019 October 15, 2024 Yes 2.7% 2.6% senior notes $500 May 2020 October 15, 2025 Yes 2.8% 1.3% senior notes $600 August 2021 October 15, 2026 Yes 1.5% 1.4% senior notes $500 October 2020 October 15, 2027 Yes 1.6% _____________ (1) The Company may redeem the notes in whole at any time or in part from time to time, at a redemption price equal to the greater of 100% of their principal amount or the present value of the remaining scheduled payments discounted to the redemption date, plus accrued and unpaid interest. In addition, the 4.75% senior notes and 5.75% senior notes are redeemable at a redemption price of 100% of their principal amount, plus accrued and unpaid interest, on or after the date that is three months prior to the final maturity date of the notes. The 2.5% senior notes, the 2.6% senior notes and the 1.3% senior notes are redeemable at a redemption price of 100% of their principal amount, plus accrued and unpaid interest, on or after the date that is one month prior to the final maturity date of the notes. The 1.4% senior notes are redeemable at a redemption price of 100% of their principal amount, plus accrued and unpaid interest, on or after the date that is two months prior to the final maturity of the notes. (2) Interest is payable semi-annually on each of the series of senior notes. The annual effective interest rate is calculated after giving effect to the amortization of debt issuance costs and the discount, if applicable. All series of homebuilding senior notes and borrowings under the homebuilding revolving credit facility are senior obligations and rank pari passu in right of payment to all existing and future unsecured indebtedness and senior to all existing and future indebtedness expressly subordinated to them. The homebuilding senior notes and borrowings under the homebuilding revolving credit facility are guaranteed by entities that hold approximately 76% of the Company’s assets. Upon the occurrence of both a change of control of the Company and a ratings downgrade event, as defined in the indentures governing its senior notes, the Company would be required in certain circumstances to offer to repurchase these notes at 101% of their principal amount, along with accrued and unpaid interest. Also, a change of control as defined in the revolving credit facility would constitute an event of default under the revolving credit facility, which could result in the acceleration of any borrowings outstanding under the facility and the termination of the commitments thereunder. The Company’s homebuilding revolving credit facility and the homebuilding senior notes are guaranteed by D.R. Horton, Inc.’s significant wholly-owned homebuilding subsidiaries. In July 2019, the Board of Directors authorized the repurchase of up to $500 million of the Company’s debt securities. The authorization has no expiration date. All of the $500 million authorization was remaining at September 30, 2022. Forestar Forestar has a $410 million senior unsecured revolving credit facility with an uncommitted accordion feature that could increase the size of the facility to $600 million, subject to certain conditions and availability of additional bank commitments. The facility also provides for the issuance of letters of credit with a sublimit equal to the greater of $100 million and 50% of the total revolving credit commitments. Borrowings under the revolving credit facility are subject to a borrowing base calculation based on the book value of Forestar’s real estate assets and unrestricted cash. Letters of credit issued under the facility reduce the available borrowing capacity. At September 30, 2022, there were no borrowings outstanding and $53.3 million of letters of credit issued under the revolving credit facility, resulting in available capacity of $356.7 million. In October 2022, Forestar’s senior unsecured revolving credit facility was amended to extend its maturity date to October 28, 2026. The Forestar revolving credit facility includes customary affirmative and negative covenants, events of default and financial covenants. The financial covenants require Forestar to maintain a minimum level of tangible net worth, a minimum level of liquidity and a maximum allowable leverage ratio. These covenants are measured as defined in the credit agreement governing the facility and are reported to the lenders quarterly. A failure to comply with these financial covenants could allow the lending banks to terminate the availability of funds under the revolving credit facility or cause any outstanding borrowings to become due and payable prior to maturity. As of September 30, 2022, Forestar had $700 million principal amount of senior notes issued pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended, which represent unsecured obligations of Forestar. These notes include $400 million principal amount of 3.85% senior notes that mature May 15, 2026 and $300 million principal amount of 5.0% senior notes that mature March 1, 2028. The annual effective interest rate of the notes after giving effect to the amortization of financing costs is 4.1% and 5.2%, respectively. Forestar’s senior notes may be redeemed prior to maturity, subject to certain limitations and premiums defined in the indenture agreements. Forestar’s revolving credit facility and its senior notes are guaranteed by Forestar’s wholly-owned subsidiaries that are not immaterial subsidiaries or have not been designated as unrestricted subsidiaries. They are not guaranteed by D.R. Horton, Inc. or any of the subsidiaries that guarantee the debt of the Company’s homebuilding, financial services or rental operations. At September 30, 2022, Forestar was in compliance with all of the covenants, limitations and restrictions of its revolving credit facility and senior note obligations. In April 2020, Forestar’s Board of Directors authorized the repurchase of up to $30 million of Forestar’s debt securities. The authorization has no expiration date. All of the $30 million authorization was remaining at September 30, 2022. Financial Services The Company’s mortgage subsidiary, DHI Mortgage, has a mortgage repurchase facility that provides financing and liquidity to DHI Mortgage by facilitating purchase transactions in which DHI Mortgage transfers eligible loans to the counterparties upon receipt of funds from the counterparties. DHI Mortgage then has the right and obligation to repurchase the purchased loans upon their sale to third-party purchasers in the secondary market or within specified time frames from 45 to 60 days in accordance with the terms of the mortgage repurchase facility. The total capacity of the facility is $1.6 billion; however, the capacity automatically increases during certain higher volume periods and can be further increased through additional commitments. The total capacity of the facility at September 30, 2022 was $2.2 billion, and its maturity date is February 17, 2023. As of September 30, 2022, $2.5 billion of mortgage loans held for sale with a collateral value of $2.4 billion were pledged under the mortgage repurchase facility. As a result of advance paydowns totaling $827.2 million, DHI Mortgage had an obligation of $1.6 billion outstanding under the mortgage repurchase facility at September 30, 2022 at a 4.6% annual interest rate. The mortgage repurchase facility is not guaranteed by D.R. Horton, Inc. or any of the subsidiaries that guarantee the debt of the Company’s homebuilding, Forestar or rental operations. The facility contains financial covenants as to the mortgage subsidiary’s minimum required tangible net worth, its maximum allowable leverage ratio and its minimum required liquidity. These covenants are measured and reported to the lenders monthly. At September 30, 2022, DHI Mortgage was in compliance with all of the conditions and covenants of the mortgage repurchase facility. Rental In March 2022, the Company’s rental subsidiary, DRH Rental, entered into a $625 million senior unsecured revolving credit facility with an uncommitted accordion feature that could increase the size of the facility to $1.25 billion, subject to certain conditions and availability of additional bank commitments. On subsequent occasions, DRH Rental utilized the accordion feature to obtain additional commitments, thereby increasing the size of the facility to $975 million at September 30, 2022. Availability under the rental revolving credit facility is subject to a borrowing base calculation based on the book value of DRH Rental’s real estate assets and unrestricted cash. At September 30, 2022, the borrowing base limited the available capacity under the facility to $811.9 million. The facility also provides for the issuance of letters of credit with a sublimit equal to the greater of $100 million and 50% of the total revolving credit commitments. The maturity date of the facility is March 4, 2026. At September 30, 2022, there were $800 million of borrowings outstanding at a 4.8% annual interest rate and no letters of credit issued under the facility, resulting in available capacity of $11.9 million. In November 2022, DRH Rental utilized the accordion feature and increased the size of the revolving credit facility to $1.025 billion through an additional commitment. The revolving credit facility includes customary affirmative and negative covenants, events of default and financial covenants. The financial covenants require DRH Rental to maintain a minimum level of tangible net worth, a minimum level of liquidity and a maximum allowable leverage ratio. These covenants are measured as defined in the credit agreement governing the facility and are reported to the lenders quarterly. A failure to comply with these financial covenants could allow the lending banks to terminate the availability of funds under the revolving credit facility or cause any outstanding borrowings to become due and payable prior to maturity. At September 30, 2022, DRH Rental was in compliance with all of the covenants, limitations and restrictions of its revolving credit facility. DRH Rental’s revolving credit facility is guaranteed by DRH Rental’s wholly-owned subsidiaries that are not immaterial subsidiaries or have not been designated as unrestricted subsidiaries. The rental revolving credit facility is not guaranteed by D.R. Horton, Inc. or any of the subsidiaries that guarantee the debt of the Company’s homebuilding, Forestar or financial services operations.

SEC Schedule, 12-29, Real Estate Companies, Investment in Mortgage Loans on Real Estate [Abstract]
Mortgage Loans	MORTGAGE LOANS Mortgage Loans Held for Sale and Related Derivatives Mortgage loans held for sale consist primarily of single-family residential loans collateralized by the underlying property. The Company typically sells the servicing rights for the majority of loans when the loans are sold. Servicing rights retained are typically sold within six months of loan origination. At September 30, 2022, mortgage loans held for sale of $2.39 billion had an aggregate outstanding principal balance of $2.51 billion. At September 30, 2021, mortgage loans held for sale of $2.03 billion had an aggregate outstanding principal balance of $1.97 billion. During the years ended September 30, 2022, 2021 and 2020, mortgage loans originated totaled $19.5 billion, $16.0 billion and $12.2 billion, respectively, and mortgage loans sold totaled $18.9 billion, $15.5 billion and $11.8 billion, respectively. The Company had gains on sales of loans and servicing rights of $561.7 million, $619.1 million and $437.2 million during the years ended September 30, 2022, 2021 and 2020, respectively. Net gains on sales of loans and servicing rights are included in revenues in the consolidated statements of operations. During fiscal 2022, approximately 62% of the Company’s mortgage loans were sold directly to Fannie Mae, Freddie Mac or into securities backed by Ginnie Mae, and 30% were sold to one other major financial entity. To manage the interest rate risk inherent in its mortgage operations, the Company hedges its risk using derivative instruments, generally forward sales of mortgage-backed securities (MBS), which are referred to as “hedging instruments” in the following discussion. The Company does not enter into or hold derivatives for trading or speculative purposes. Newly originated loans that have been closed but not committed to third-party purchasers are hedged to mitigate the risk of changes in their fair value. Hedged loans are committed to third-party purchasers typically within three days after origination. The notional amounts of the hedging instruments used to hedge mortgage loans held for sale may vary in relationship to the underlying loan amounts, depending on the movements in the value of each hedging instrument relative to the value of the underlying mortgage loans. The fair value change related to the hedging instruments generally offsets the fair value change in the mortgage loans held for sale. The net fair value change, which for the years ended September 30, 2022, 2021 and 2020 was not significant, is recognized in revenues in the consolidated statements of operations. At September 30, 2022 and 2021, the Company’s mortgage loans held for sale that were not committed to third-party purchasers totaled $1.6 billion and $1.3 billion, respectively. The Company also uses hedging instruments as part of a program to offer below market interest rate financing to its homebuyers. At September 30, 2022 and 2021, the Company had MBS totaling $532.4 million and $834.6 million, respectively, that did not yet have interest rate lock commitments (IRLCs) or closed loans created or assigned and recorded an asset of $4.8 million and $1.1 million, respectively, for the fair value of such MBS position. Loan Commitments and Related Derivatives The Company is party to IRLCs, which are extended to borrowers who have applied for loan funding and meet defined credit and underwriting criteria. At September 30, 2022 and 2021, the notional amount of IRLCs, which are accounted for as derivative instruments recorded at fair value, totaled $4.0 billion and $1.5 billion, respectively. The Company manages interest rate risk related to its IRLCs through the use of best-efforts whole loan delivery commitments and hedging instruments. These instruments are considered derivatives in an economic hedge and are accounted for at fair value with gains and losses recognized in revenues in the consolidated statements of operations. At September 30, 2022 and 2021, the notional amount of best-efforts whole loan delivery commitments totaled $23.5 million and $88.8 million, respectively, and the notional amount of hedging instruments related to the remaining IRLCs totaled $3.8 billion and $1.4 billion, respectively. Other Mortgage Loans and Loss Reserves Mortgage loans are sold with limited recourse provisions derived from industry-standard representations and warranties in the relevant agreements. These representations and warranties primarily involve the absence of misrepresentations by the borrower or other parties, the appropriate underwriting of the loan and in some cases, a required minimum number of payments to be made by the borrower. The Company generally does not retain any other continuing interest related to mortgage loans sold in the secondary market. The majority of other mortgage loans consists of loans repurchased due to these limited recourse obligations. Typically, these loans are impaired, and some result in real estate owned through the foreclosure process. At September 30, 2022 and 2021, the Company’s total other mortgage loans and real estate owned, before loss reserves, totaled $14.5 million and $15.0 million, respectively. The Company has recorded reserves for estimated losses on other mortgage loans, real estate owned and future loan repurchase obligations due to the limited recourse provisions, all of which are recorded as reductions of revenue. The loss reserve for loan repurchase and settlement obligations is estimated based on historical experience, analysis of the volume of mortgages originated, discussions with mortgage purchasers and current housing and credit market conditions, as well as known and projected mortgage loan repurchase requests. The reserve balances at September 30, 2022 and 2021 totaled $7.5 million and $5.1 million, respectively. Other mortgage loans and real estate owned net of the related loss reserves are included in other assets, while loan repurchase obligations are included in accrued expenses and other liabilities in the Company’s consolidated balance sheets.

The effective tax rates for all years include an expense for state income taxes and tax benefits related to stock-based compensation and federal energy efficient homes tax credits. The effective tax rate for fiscal 2020 also includes a reduction for a tax benefit related to the release of a valuation allowance against the Company’s state deferred tax assets. The federal energy efficient homes tax credit was retroactively extended to qualifying homes closed from January 1, 2022 through December 31, 2032 as a result of the enactment of the Inflation Reduction Act (IRA) that was signed into law on August 16, 2022. Other tax related provisions of the IRA had no material impact on the Company’s financial statements. Reconciliation of Expected Income Tax Expense Differences between income tax expense and tax computed by applying the federal statutory rate of 21% to income before income taxes during each year is due to the following: Year Ended September 30, 2022 2021 2020 (In millions) Income taxes at federal statutory rate $ 1,602.2 $ 1,124.8 $ 626.4 Increase (decrease) in tax resulting from: State income taxes, net of federal benefit 210.0 166.9 79.1 Valuation allowance (2.1) (3.3) (11.2) Tax credits (100.8) (116.3) (93.4) Excess tax benefit from stock-based compensation (20.1) (38.4) (22.3) Tax contingencies — (6.0) 8.9 Other 44.9 37.4 15.0 Total income tax expense $ 1,734.1 $ 1,165.1 $ 602.5 Deferred Income Taxes Deferred tax assets and liabilities reflect the tax consequences of temporary differences between the financial statement bases of assets and liabilities and their tax bases, tax losses and credit carryforwards. Components of deferred income taxes are summarized as follows: September 30, 2022 2021 (In millions) Deferred tax assets: Inventory costs $ 74.0 $ 63.5 Inventory impairments 9.5 12.7 Warranty and construction defect costs 239.5 190.5 Net operating loss carryforwards 44.1 11.7 Tax credit carryforwards 6.4 1.6 Incentive compensation plans 84.7 77.5 Other 12.7 15.6 Total deferred tax assets 470.9 373.1 Valuation allowance (17.9) (4.2) Total deferred tax assets, net of valuation allowance 453.0 368.9 Deferred tax liabilities: Deferral of profit on home closings 209.4 166.7 Depreciation of fixed assets 30.5 14.4 Deferral of income 18.5 2.0 Undistributed earnings of subsidiary 27.3 10.2 Other 26.2 20.3 Total deferred tax liabilities 311.9 213.6 Deferred income taxes, net $ 141.1 $ 155.3 The Company has $30.9 million of tax benefits for a federal net operating loss (NOL) carryforward acquired in the Vidler acquisition. The utilization of the federal NOL is subject to IRC Section 382 limitations; however, it is expected that all of the federal NOL will be utilized within the carryforward period. D.R. Horton has $12.0 million of tax benefits for state NOL carryforwards that expire at various times depending on the tax jurisdiction. Of the total amount, $4.3 million of the tax benefits expire over the next ten years and the remaining $7.7 million expire from fiscal years 2033 to 2042. Forestar has $1.2 million of tax benefits for state NOL carryforwards that expire at various times depending on the tax jurisdiction. The accounting for deferred taxes is based upon estimates of future results. Differences between the anticipated and actual outcomes of these future results could have a material impact on the Company’s consolidated results of operations or financial position. Also, changes in existing federal and state tax laws and tax rates could affect future tax results and the valuation of the Company’s deferred tax assets. Valuation Allowance The Company has a valuation allowance of $17.9 million and $4.2 million at September 30, 2022 and 2021, respectively, related to deferred tax assets for state NOL, state capital loss and tax credit carryforwards that are expected to expire before being realized. Of the $17.9 million valuation allowance, $15.8 million relates to state NOL, state capital loss and tax credit carryforwards acquired in the Vidler acquisition. The Company will continue to evaluate both the positive and negative evidence in determining the need for a valuation allowance with respect to the remaining state NOL, state capital loss and tax credit carryforwards. Any reversal of the valuation allowance in future periods will impact the Company’s effective tax rate. Unrecognized Tax Benefits Unrecognized tax benefits are the differences between tax positions taken or expected to be taken in a tax return and the benefits recognized in the financial statements. A reconciliation of the beginning and ending amounts of unrecognized tax benefits for fiscal 2022 and 2021 is as follows: Year Ended September 30, 2022 2021 (In millions) Unrecognized tax benefits, beginning of year $ 2.9 $ 8.9 Additions attributable to tax positions taken in the current year — 1.5 Additions attributable to tax positions taken in prior years — — Settlements — (7.5) Unrecognized tax benefits, end of year $ 2.9 $ 2.9 The total amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate is $2.9 million. The Company had no accrued interest or penalties related to unrecognized tax benefits at September 30, 2022. The Company classifies interest expense and penalties on income taxes as income tax expense. Regulations and Legislation D.R. Horton is subject to federal income tax and state income tax in multiple jurisdictions. The statute of limitations for D.R. Horton’s major tax jurisdictions remains open for examination for fiscal years 2018 through 2022. An audit by the Internal Revenue Service of a federal refund claim related to the retroactive extension of energy efficient homes tax credits for fiscal 2018 and additional energy efficient tax credits for fiscal 2017 was completed during the current fiscal year with no material adjustments. D.R. Horton is under audit by various states; however, the Company is not aware of any significant findings by the state taxing authorities. Forestar is subject to federal income tax and state income tax in multiple jurisdictions. The statute of limitations for Forestar’s federal income tax remains open for examination for tax years 2019 through 2022. The statute of limitations for Forestar’s major state tax jurisdictions generally remain open for examination for tax years 2017 through 2022.

In addition to base pay, eligible employees may participate in the Company’s 401(k) plan, employee stock purchase plan, short-term incentive bonus program and/or its stock compensation plans, as described below. Deferred Compensation Plans The Company has a 401(k) plan for all employees who have been with the Company for a period of six months or more. The Company matches portions of employees’ voluntary contributions. The Company recorded $35.4 million, $30.3 million and $23.4 million of expense for matching contributions in fiscal 2022, 2021 and 2020, respectively. The Company’s Supplemental Executive Retirement Plan (SERP) is a non-qualified deferred compensation program that provides benefits payable to certain management employees upon retirement, death or termination of employment. Under the SERP, the Company accrues an unfunded benefit based on a percentage of the eligible employees’ salaries, as well as an interest factor based upon a predetermined formula. The Company’s liabilities related to the SERP were $52.1 million and $50.4 million at September 30, 2022 and 2021, respectively. The Company recorded $7.7 million, $7.0 million and $6.5 million of expense for this plan in fiscal 2022, 2021 and 2020, respectively. The Company has a deferred compensation plan available to a select group of employees which allows participating employees to contribute compensation into the plan on a before tax basis and defer income taxation on the contributions until the funds are withdrawn from the plan. The participating employees designate investments for their contributions; however, the Company is not required to invest the contributions in the designated investments. The Company’s net liabilities related to the deferred compensation plan were $119.5 million and $124.5 million at September 30, 2022 and 2021, respectively. The Company records as expense the amount that the employee contributions would have earned had the funds been invested in the designated investments. Related to this plan, the Company recorded a credit to expense of $24.0 million in fiscal 2022 and recorded charges to expense of $21.7 million and $5.3 million in fiscal 2021 and 2020, respectively. Employee Stock Purchase Plan The Company’s Employee Stock Purchase Plan provides eligible employees the opportunity to purchase common stock of the Company at a discounted price of 85% of the fair market value of the stock on the designated dates of purchase. The price to eligible employees may be further discounted depending on the average fair market value of the stock during the period and certain other criteria. Under the terms of the plan, the total fair market value of common stock that an eligible employee may purchase each year is limited to the lesser of 15% of the employee’s annual compensation or $25,000. Under the plan, employees purchased 164,193 shares for $10.7 million in fiscal 2022, 112,995 shares for $7.5 million in fiscal 2021 and 131,348 shares for $5.6 million in fiscal 2020. At September 30, 2022, the Company had 2.6 million shares of common stock reserved for issuance pursuant to the Employee Stock Purchase Plan. Incentive Bonus Plan The Company’s Incentive Bonus Plan provides for the Compensation Committee to award short-term performance bonuses to senior management based upon the level of achievement of certain criteria. For fiscal 2022, 2021 and 2020, the Compensation Committee approved awards whereby certain executive officers could earn performance bonuses based upon percentages of the Company’s pre-tax income. Compensation expense related to these plans was $40.5 million, $61.6 million and $34.3 million in fiscal 2022, 2021 and 2020, respectively. Stock-Based Compensation The Company’s Stock Incentive Plan provides for the granting of stock options and restricted stock units to executive officers, other key employees and non-management directors. Restricted stock unit (RSU) awards may be based on service over a requisite time period (time-based) or on performance (performance-based). RSU equity awards represent the contingent right to receive one share of the Company’s common stock per RSU if the vesting conditions and/or performance criteria are satisfied. The RSUs have no dividend or voting rights until vested. At September 30, 2022, the Company had 8.5 million shares of common stock reserved for issuance and 4.2 million shares available for future grants under the Stock Incentive Plan. Time-Based Restricted Stock Unit Equity Awards During fiscal 2022, 2021 and 2020, time-based RSUs were granted to the Company’s executive officers, other key employees and non-management directors (collectively, approximately 1,200, 1,030 and 960 recipients, respectively). These awards vest annually in equal installments over periods of three The following table provides additional information related to time-based RSU activity during fiscal 2022, 2021 and 2020. The number of RSUs vested includes shares of common stock withheld by the Company on behalf of employees to satisfy the tax withholding requirements. Year Ended September 30, 2022 2021 2020 Number of Weighted Average Number of Weighted Average Number of Weighted Average Outstanding at beginning of year 3,817,265 $ 46.16 4,725,701 $ 34.79 4,889,534 $ 33.01 Granted 1,153,124 74.96 856,615 83.13 1,657,935 35.98 Vested (1,402,642) 41.44 (1,644,263) 33.26 (1,651,840) 30.85 Cancelled (101,653) 51.22 (120,788) 39.16 (169,928) 33.24 Outstanding at end of year 3,466,094 $ 57.50 3,817,265 $ 46.16 4,725,701 $ 34.79 The total fair value of shares vested on the vesting date during fiscal 2022, 2021 and 2020 was $120.1 million, $131.3 million and $95.6 million, respectively. For fiscal 2022, 2021 and 2020, compensation expense related to time-based RSUs was $63.6 million, $56.5 million and $50.6 million, respectively. At September 30, 2022, there was $147.6 million of unrecognized compensation expense related to unvested time-based RSU awards. This expense is expected to be recognized over a weighted average period of 2.6 years. Performance-Based Restricted Stock Unit Equity Awards During fiscal 2022, 2021 and 2020, performance-based RSU equity awards that vest at the end of three-year performance periods were granted to the Company’s executive officers. The number of units that ultimately vest depends on the Company’s relative position as compared to its peers in achieving certain performance criteria and can range from 0% to 200% of the number of units granted. The performance criteria are total shareholder return, return on investment, SG&A expense containment and gross profit. Compensation expense related to these grants is based on the Company’s performance against its peer group, the elapsed portion of the performance period and the grant date fair value of the award. The following table provides additional information related to the performance-based RSUs outstanding at September 30, 2022. Grant Date Vesting Date Target Number of Performance Units Grant Date Fair Value per Unit Compensation Expense 2022 2021 2020 (In millions) November 2019 September 2022 360,000 $ 52.54 $ 8.6 $ 10.1 $ 9.3 November 2020 September 2023 360,000 70.60 12.5 12.5 — October 2021 (1) September 2024 430,000 80.58 14.3 — — $ 35.4 $ 22.6 $ 9.3 _________________________ (1) The performance RSUs granted in October 2021 totaled 390,000; however, in March 2022, the Compensation Committee of the Company’s Board of Directors approved an amendment and restatement of this award to increase the RSUs granted from 390,000 to 430,000. Concurrent with this change, the Compensation Committee amended the executive officer short-term performance bonus plan to reduce the amount of the award that could be earned. In October 2022, the Compensation Committee approved the issuance of the performance-based RSUs that vested in September 2022 in the form of 585,000 shares of common stock to satisfy the awards. Stock Options Stock options are granted at exercise prices which equal the market value of the Company’s common stock at the date of the grant. The options outstanding at September 30, 2022 are all exercisable and expire 10 years after the dates on which they were granted. The Company did not grant stock options during fiscal 2022, 2021 or 2020. The following table provides information related to stock option activity during those years.

The intrinsic value of a stock option is the amount by which the market value of the underlying stock exceeds the option exercise price. The aggregate intrinsic value of options outstanding and exercisable at September 30, 2022 was $35.8 million. Exercise prices for options outstanding at September 30, 2022 ranged from $23.57 to $23.86. The weighted average remaining contractual lives of options outstanding and exercisable at September 30, 2022 is 1.1 years.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Warranty Claims The Company provides its homebuyers with warranties for defects in structural elements, mechanical systems and other construction components of the home. Warranty liabilities are established by charging cost of sales for each home delivered based on management’s estimate of expected warranty-related costs and by accruing for existing warranty claims. The Company’s warranty liability is based upon historical warranty cost experience in each market in which it operates and is adjusted to reflect qualitative risks associated with the types of homes built and the geographic areas in which they are built. The estimation of these costs is subject to a high degree of variability due to uncertainties related to these factors. Due to the high degree of judgment required in establishing the liability for warranty claims, actual future costs could differ significantly from current estimated amounts, and it is not possible for the Company to make a reasonable estimate of the possible loss or range of loss in excess of its warranty liability. Changes in the Company’s warranty liability during fiscal 2022 and 2021 were as follows: September 30, 2022 2021 (In millions) Warranty liability, beginning of year $ 376.3 $ 310.2 Warranties issued 185.8 154.5 Changes in liability for pre-existing warranties 15.1 3.8 Settlements made (122.9) (92.2) Warranty liability, end of year $ 454.3 $ 376.3 Legal Claims and Insurance The Company is named as a defendant in various claims, complaints and other legal actions in the ordinary course of business. At any point in time, the Company is managing several hundred individual claims related to construction defect matters, personal injury claims, employment matters, land development issues, contract disputes and other matters. The Company has established reserves for these contingencies based on the estimated costs of pending claims and the estimated costs of anticipated future claims related to previously closed homes. The estimated liabilities for these contingencies were $729.1 million and $577.5 million at September 30, 2022 and 2021, respectively, and are included in accrued expenses and other liabilities in the consolidated balance sheets. Approximately 99% of these reserves related to construction defect matters at both September 30, 2022 and 2021. Expenses related to the Company’s legal contingencies were $138.0 million, $72.4 million and $64.4 million in fiscal 2022, 2021 and 2020, respectively. The Company’s reserves for construction defect claims include the estimated costs of both known claims and anticipated future claims. As of September 30, 2022, no individual existing claim was material to the Company’s financial statements. The Company has closed a significant number of homes during recent years and may be subject to future construction defect claims on these homes. Although regulations vary from state to state, construction defect issues can generally be reported for up to ten years after the home has closed in many states in which the Company operates. Historical data and trends regarding the frequency of claims incurred and the costs to resolve claims relative to the types of products and markets where the Company operates are used to estimate the construction defect liabilities for both existing and anticipated future claims. These estimates are subject to ongoing revision as the circumstances of individual pending claims and historical data and trends change. Adjustments to estimated reserves are recorded in the accounting period in which the change in estimate occurs. Historical trends in construction defect claims have been inconsistent, and the Company believes they may continue to fluctuate. The Company also believes that fluctuations in housing market conditions can affect the frequency and cost of construction defect claims. If the ultimate resolution of construction defect claims resulting from the Company’s home closings in prior years varies from current expectations, it could significantly change the Company’s estimates regarding the frequency and timing of claims incurred and the costs to resolve existing and anticipated future claims, which would impact the construction defect reserves in the future. If the frequency of claims incurred or costs of existing and future legal claims significantly exceed the Company’s current estimates, they will have a significant negative impact on its future earnings and liquidity. Changes in the Company’s legal claims reserves during fiscal 2022 and 2021 were as follows: September 30, 2022 2021 (In millions) Reserves for legal claims, beginning of year $ 577.5 $ 473.8 Increase in reserves 186.1 131.8 Payments (34.5) (28.1) Reserves for legal claims, end of year $ 729.1 $ 577.5 In the majority of states in which it operates, the Company generally has, and requires the majority of the subcontractors it uses to have, general liability insurance which includes construction defect coverage. The Company’s general liability insurance policies protect it against a portion of its risk of loss from construction defect and other claims and lawsuits. The Company estimates and records receivables under these policies for known claims and anticipated future construction defect claims on previously closed homes and other legal claims and lawsuits incurred in the ordinary course of business when recovery is probable. However, because the self-insured retentions under these policies are significant, the Company anticipates it will largely be self-insured. The Company’s estimated insurance receivables from estimated losses for pending legal claims and anticipated future claims related to previously closed homes totaled $137.9 million and $109.5 million at September 30, 2022 and 2021, respectively, and are included in other assets in the consolidated balance sheets. Additionally, the Company may have the ability to recover a portion of its losses from its subcontractors and their insurance carriers when the Company has been named as an additional insured on their insurance policies. In some states where the Company believes it is too difficult or expensive for its subcontractors to obtain general liability insurance, the Company has waived its normal subcontractor general liability insurance requirements to obtain lower costs from subcontractors. In these states, the Company purchases insurance policies from either third-party carriers or its wholly-owned captive insurance subsidiary and names certain subcontractors as additional insureds. The policies issued by the captive insurance subsidiary and the policies issued on or after June 1, 2020 by third-party carriers essentially represent self-insurance of these risks by the Company. The Company is self-insured for the deductible amounts under its workers’ compensation insurance policies. The deductibles vary by policy year, but in no years exceed $0.5 million per occurrence. The deductible for the 2021, 2022 and 2023 policy years is $0.5 million per occurrence. The estimation of losses related to these reserves and the related estimates of recoveries from insurance policies are subject to a high degree of variability due to uncertainties such as trends in construction defect claims relative to the Company’s markets and the types of products built, claim frequency, claim settlement costs and patterns, insurance industry practices and legal interpretations, among others. Due to the high degree of judgment required in establishing reserves for these contingencies, actual future costs and recoveries from insurance could differ significantly from current estimated amounts, and it is not possible for the Company to make a reasonable estimate of the possible loss or range of loss in excess of its reserves. Land and Lot Purchase Contracts The Company enters into land and lot purchase contracts to acquire land or lots for the construction of homes. At September 30, 2022, the Company had total deposits of $1.6 billion, consisting of cash deposits of $1.5 billion and promissory notes and surety bonds of $90.5 million, related to contracts to purchase land and lots with a total remaining purchase price of approximately $19.7 billion. The majority of land and lots under contract are currently expected to be purchased within three years. Of these amounts, $131.7 million of the deposits related to contracts with Forestar to purchase land and lots with a remaining purchase price of $1.4 billion. A limited number of the homebuilding land and lot purchase contracts at September 30, 2022, representing $88.9 million of remaining purchase price, were subject to specific performance provisions that may require the Company to purchase the land or lots upon the land sellers meeting their respective contractual obligations. Of the $88.9 million remaining purchase price subject to specific performance provisions, $66.2 million related to contracts between the homebuilding segment and Forestar. During fiscal 2022 and 2021, Forestar reimbursed the homebuilding segment $8.7 million and $30.8 million, respectively, for previously paid earnest money and $58.9 million and $61.3 million, respectively, for pre-acquisition and other due diligence costs related to land purchase contracts whereby the homebuilding segment assigned its rights under contract to Forestar. Other Commitments At September 30, 2022, the Company had outstanding surety bonds of $2.8 billion and letters of credit of $273.3 million to secure performance under various contracts. Of the total letters of credit, $220.0 million were issued under the homebuilding revolving credit facility and $53.3 million were issued under Forestar’s revolving credit facility. The Company leases office space and equipment under non-cancelable operating leases. At September 30, 2022, the future minimum annual lease payments under these agreements are as follows (in millions): Fiscal 2023 $ 23.2 Fiscal 2024 14.9 Fiscal 2025 7.3 Fiscal 2026 3.4 Fiscal 2027 1.5 Thereafter — $ 50.3 Rent expense was $38.1 million, $31.7 million and $31.5 million for fiscal 2022, 2021 and 2020, respectively.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value measurements are used for the Company’s mortgage loans held for sale, mortgage servicing rights, IRLCs and other derivative instruments on a recurring basis and are used for inventories, other mortgage loans, rental properties and real estate owned on a nonrecurring basis, when events and circumstances indicate that the carrying value is not recoverable. The fair value hierarchy and its application to the Company’s assets and liabilities is as follows: • Level 1 – Valuation is based on quoted prices in active markets for identical assets and liabilities. The Company does not currently have any assets or liabilities measured at fair value using Level 1 inputs. • Level 2 – Valuation is determined from quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar instruments in markets that are not active, or by model-based techniques in which all significant inputs are observable in the market. The Company’s assets and liabilities measured at fair value using Level 2 inputs on a recurring basis are as follows: ◦ Mortgage loans held for sale - The fair value of these loans is generally calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. Closed mortgage loans are typically sold shortly after origination, which limits exposure to nonperformance by loan buyer counterparties to a short time period. In addition, the Company actively monitors the financial strength of its counterparties. ◦ IRLCs - The fair value of IRLCs is calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. These valuations do not contain adjustments for expirations as any expired commitments are excluded from the fair value measurement. The Company generally only issues IRLCs for products that meet specific purchaser guidelines. Should any purchaser become insolvent, the Company would not be required to close the transaction based on the terms of the commitment. Since not all IRLCs will become closed loans, the Company adjusts its fair value measurements for the estimated amount of IRLCs that will not close. ◦ Loan sale commitments and hedging instruments - The fair values of best-efforts and mandatory loan sale commitments and derivative instruments such as forward sales of MBS that are utilized as hedging instruments are calculated by reference to quoted prices for similar assets. The Company mitigates exposure to nonperformance risk associated with derivative instruments by limiting the number of counterparties and actively monitoring their financial strength and creditworthiness. Further, the Company’s derivative contracts typically have short-term durations with maturities from one to four months. Accordingly, the Company’s risk of nonperformance relative to its derivative positions is not significant. The Company’s assets measured at fair value using Level 2 inputs on a nonrecurring basis are a limited number of mortgage loans held for sale with some degree of impairment affecting their marketability and are reported at the lower of carrying value or fair value. When available, fair value is determined by reference to quoted prices in the secondary markets for such assets. After consideration of nonperformance risk, no additional adjustments were made to the fair value measurements of mortgage loans held for sale, IRLCs or hedging instruments. • Level 3 – Valuation is typically derived from model-based techniques in which at least one significant input is unobservable and based on the Company’s own estimates about the assumptions that market participants would use to value the asset or liability. The Company’s assets measured at fair value using Level 3 inputs on a recurring basis are its mortgage servicing rights and a limited number of mortgage loans held for sale with some degree of impairment affecting their marketability and for which reference to quoted prices in the secondary markets is not available. The Company’s assets measured at fair value using Level 3 inputs that are typically reported at the lower of carrying value or fair value on a nonrecurring basis are as follows: ◦ Inventory held and used - In assessing impairment indicators of its inventory held and used, the Company performs an analysis of the undiscounted cash flows estimated to be generated by those assets. The most significant factors used to estimate undiscounted future cash flows include pricing and incentive levels actually realized by the community, the rate at which the homes are sold and the costs incurred to develop the lots and construct the homes. Inventory held and used measured at fair value represents those communities for which the estimated undiscounted cash flows are less than their carrying amounts and therefore, the Company recorded impairments during the period to record the inventory at fair value calculated based on its discounted estimated future cash flows. ◦ Inventory available for sale - The factors considered in determining fair values of the Company’s land held for sale primarily include actual sale contracts and recent offers received from outside third parties, and may also include prices for land in recent comparable sales transactions and other market analysis. If the estimated fair value less the costs to sell an asset is less than the asset’s current carrying value, the asset is written down to its estimated fair value less costs to sell. ◦ Certain mortgage loans held for sale - A limited number of mortgage loans held for sale have some degree of impairment affecting their marketability. For some of these loans, quoted prices in the secondary market are not available and therefore, a cash flow valuation model is used to determine fair value. ◦ Certain other mortgage loans, rental properties and real estate owned - Other mortgage loans include performing and nonperforming mortgage loans, which often become real estate owned through the foreclosure process. The fair values of other mortgage loans, rental properties and real estate owned are determined based on the Company’s assessment of the value of the underlying collateral or the value of the property, as applicable. The Company uses different methods to assess the value of the properties, which may include broker price opinions, appraisals or cash flow valuation models. The following tables summarize the Company’s assets and liabilities measured at fair value on a recurring basis at September 30, 2022 and 2021, and the changes in the fair value of the Level 3 assets during fiscal 2022 and 2021. Fair Value at September 30, 2022 Balance Sheet Location Level 1 Level 2 Level 3 Total (In millions) Mortgage loans held for sale (1) Mortgage loans held for sale $ — $ 2,356.1 $ 14.1 $ 2,370.2 Mortgage servicing rights (2) Other assets — — 10.6 10.6 Derivatives not designated as hedging instruments (3): Interest rate lock commitments (4) Other assets and other liabilities — (135.8) — (135.8) Mortgage hedging instruments and commitments (5) Other assets and other liabilities — 317.8 — 317.8 Fair Value at September 30, 2021 Balance Sheet Location Level 1 Level 2 Level 3 Total (In millions) Mortgage loans held for sale (1) Mortgage loans held for sale $ — $ 2,009.4 $ 11.7 $ 2,021.1 Mortgage servicing rights (2) Other assets — — 4.1 4.1 Derivatives not designated as hedging instruments (3): Interest rate lock commitments (4) Other assets and other liabilities — 17.2 — 17.2 Mortgage hedging instruments and commitments Other assets — 8.5 — 8.5 Level 3 Assets at Fair Value for the Year Ended September 30, 2022 Balance at Net realized and unrealized gains (losses) Purchases / Originations Sales and Settlements Principal Reductions Net transfers to (out of) Level 3 Balance at (In millions) Mortgage loans held for sale (1) $ 11.7 $ (0.7) $ — $ (3.9) $ — $ 7.0 $ 14.1 Mortgage servicing rights (2) 4.1 (1.2) 35.3 (27.6) — — 10.6 Level 3 Assets at Fair Value for the Year Ended September 30, 2021 Balance at Net realized and unrealized gains (losses) Purchases / Originations Sales and Settlements Principal Reductions Net transfers to (out of) Level 3 Balance at (In millions) Debt securities collateralized by residential real estate $ 3.9 $ — $ — $ (3.9) $ — $ — $ — Mortgage loans held for sale (1) 15.1 0.3 — (3.3) — (0.4) 11.7 Mortgage servicing rights (2) 17.1 (0.2) 24.7 (37.5) — — 4.1 ___________________________________________ (1) The Company typically elects the fair value option upon origination for mortgage loans held for sale. Interest income earned on mortgage loans held for sale is based on contractual interest rates and included in other income. Mortgage loans held for sale valued using Level 3 inputs at September 30, 2022 and 2021 include $14.1 million and $11.7 million, respectively, of loans for which the Company elected the fair value option upon origination and did not sell into the secondary market. Mortgage loans held for sale totaling $7.0 million were transferred to Level 3 during fiscal 2022 due to significant unobservable inputs used in determining the fair value of these loans. The fair value of these mortgage loans held for sale is generally calculated considering pricing in the secondary market and adjusted for the value of the underlying collateral, including interest rate risk, liquidity risk and prepayment risk. The Company plans to sell these loans as market conditions permit. Mortgage loans totaling $0.4 million were transferred to Level 2 during fiscal 2021 because their fair value was based on actual quoted prices related to the pending sale of those loans in the secondary market. (2) Although the majority of the Company’s mortgage loans are sold on a servicing-released basis, when the servicing rights are retained, the Company records them at fair value using third-party valuations. The valuation at the time the servicing asset is retained is reflected in the purchases/originations column with subsequent changes in value classified as realized and unrealized gains (losses). The key assumptions used in the valuation, which are generally unobservable inputs, are mortgage prepayment rates, discount rates and delinquency rates, which were 12%, 11% and 8%, respectively, at September 30, 2022. (3) Fair value measurements of these derivatives represent changes in fair value, as calculated by reference to quoted prices for similar assets, and are reflected in the balance sheet as other assets or accrued expenses and other liabilities. Changes in the fair value of these derivatives are included in revenues in the consolidated statements of operations. The net fair value change in fiscal 2022 and 2021 recognized in revenues in the consolidated statements of operations was not significant. (4) The fair value of interest rate lock commitments at September 30, 2022 reflects $47.7 million of servicing release premiums in other assets and a change in fair value of $183.5 million in other liabilities. The fair value of interest rate lock commitments at September 30, 2021 reflects $17.9 million of servicing release premiums in other assets and a change in fair value of $0.7 million in other liabilities.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and include the accounts of D.R. Horton, Inc. and all of its wholly-owned, majority-owned and controlled subsidiaries, which are collectively referred to as the Company, unless the context otherwise requires. Noncontrolling interests represent the proportionate equity interests in consolidated entities that are not 100% owned by the Company. As of September 30, 2022, the Company owns a 63% controlling interest in Forestar Group Inc. (Forestar) and therefore is required to consolidate 100% of Forestar within its consolidated financial statements, and the 37% interest the Company does not own is accounted for as noncontrolling interests. All intercompany accounts, transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Revenue Recognition	Revenue Recognition Homebuilding revenue and related profit are generally recognized at the time of the closing of a sale, when title to and possession of the property are transferred to the buyer. The Company’s performance obligation, to deliver the agreed-upon home, is generally satisfied in less than one year from the original contract date. Proceeds from home closings held for the Company’s benefit at title companies are included in homebuilding cash and cash equivalents in the consolidated balance sheets. When the Company executes sales contracts with its homebuyers, or when it requires advance payment from homebuyers for custom changes, upgrades or options related to their homes, the cash deposits received are recorded as liabilities until the homes are closed or the contracts are cancelled. The Company either retains or refunds to the homebuyer deposits on cancelled sales contracts, depending upon the applicable provisions of the contract or other circumstances. Forestar’s land and lot sales revenue and related profit are generally recognized at the time of the closing of a sale, when title to and possession of the property are transferred to a third-party buyer. Forestar’s revenues from land and lot sales to D.R. Horton are eliminated in the consolidated financial statements. The Company rarely purchases unimproved land for resale, but periodically may elect to sell parcels of land that do not fit into its strategic operating plans. Revenue from land sales is typically recognized on the closing date, which is generally when performance obligations are satisfied. The Company’s rental operations develop, construct, lease and sell residential multi-family and single-family rental properties. Revenue is recognized from the sale of these properties on the closing date, which is when performance obligations are satisfied. Rental income from these properties is recognized as other income. Financial services revenues associated with the Company’s title operations are recognized as closing services are rendered and title insurance policies are issued, both of which generally occur simultaneously as each home is closed. Revenues associated with the Company’s mortgage operations primarily include net gains on the sale of mortgage loans and servicing rights. The Company typically elects the fair value option for its mortgage loan originations whereby mortgage loans held for sale are recorded at fair value based on either sale commitments or current market quotes and loan values are adjusted through revenues for subsequent changes in fair value until the loans are sold. Expected gains and losses from the sale of servicing rights are included in the measurement of all written loan commitments that are
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an initial maturity of three months or less when purchased to be cash equivalents. Proceeds from home closings held for the Company’s benefit at title companies, which totaled $494.8 million and $478.9 million at September 30, 2022 and 2021, respectively, are included in homebuilding cash and cash equivalents in the consolidated balance sheets. Cash balances of the Company’s captive insurance subsidiary, which are expected to be used to fund the subsidiary’s operations and pay future anticipated legal claims, were $64.4 million and $55.9 million at September 30, 2022 and 2021, respectively, and are included in cash and cash equivalents in the consolidated balance sheets.
Restricted Cash	Restricted Cash The Company has cash that is restricted as to its use. Restricted cash related to homebuilding and land development operations includes customer deposits that are temporarily restricted in accordance with regulatory requirements. Restricted cash related to financial services is mortgagor related funds held by the Company for taxes and insurance on an interim basis until the loans are sold.
Inventories and Cost of Sales	Inventories and Cost of Sales Inventory includes the costs of direct land acquisition, land development and construction, capitalized interest, real estate taxes and direct overhead costs incurred during development and construction. Costs incurred after projects or homes are substantially complete, such as utilities, maintenance, and cleaning, are charged to selling, general and administrative (SG&A) expense as incurred. All indirect overhead costs, such as compensation of sales personnel, division and region management, and the costs of advertising and builder’s risk insurance are charged to SG&A expense as incurred. Land and development costs are typically allocated to individual residential lots on a pro-rata basis, and the costs of residential lots are transferred to construction in progress when home construction begins. Home construction costs are specifically identified and recorded to individual homes. Cost of sales for homes closed includes the specific construction costs of each home and all applicable land acquisition, land development and related costs (both incurred and estimated to be incurred) allocated to each residential lot based upon the total number of homes expected to be closed in each community. Cost of sales for lots sold includes all applicable land acquisition, land development and related costs (both incurred and estimated to be incurred) allocated to each residential lot in the community. Any changes to the estimated total development costs subsequent to the initial home or lot closings in a community are generally allocated on a pro-rata basis to the remaining homes or lots in the community associated with the relevant development activity. Development and construction costs incurred related to the rental operations are recorded as rental property inventory. Cost of sales related to the rental operations include the specific construction costs and all applicable land acquisition, land development and related costs for each rental project. When a home is closed, the Company generally has not paid all incurred costs necessary to complete the home. A liability and a corresponding charge to cost of sales are recorded for the amount estimated to ultimately be paid related to completed homes that have been closed. Home construction budgets are compared to actual recorded costs to determine the additional costs remaining to be paid on each closed home. The Company rarely purchases land for resale. However, when the Company owns land or communities under development that do not fit into its development and construction plans, and the Company determines that it will sell the asset, the project is accounted for as land held for sale if certain criteria are met. The Company records land held for sale at the lesser of its carrying value or fair value less estimated costs to sell. At the end of each quarter, the Company reviews the performance and outlook for all of its communities and land inventories for indicators of potential impairment. If indicators of impairment are present for a community, the Company performs an impairment evaluation of the community, which includes an analysis to determine if the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts. The Company’s estimate of undiscounted cash flows from communities analyzed may change and could result in a future need to record impairment charges to adjust the carrying value of these assets to their estimated fair value. There are several factors which could lead to changes in the estimates of undiscounted future cash flows for a given community. The most significant of these includes pricing and incentive levels actually realized by the community, the rate at which the homes are sold and the costs incurred to develop the lots and construct the homes. Pricing and incentive levels are often interrelated with sales pace in a community, such that a price reduction is typically expected to increase the sales pace. Further, both of these factors are heavily influenced by the competitive pressures facing a given community from both new and existing homes. If conditions in the broader economy, homebuilding industry or specific markets in which the Company operates worsen, and as the Company evaluates specific community pricing and incentives, construction and development plans, and its overall land sale strategies, it may be required to evaluate additional communities for potential impairment. This may result in impairment charges which could be significant. When events or circumstances indicate that the carrying values on finished homes in substantially completed communities and completed rental properties are greater than the fair values less estimated costs to sell these homes, impairment charges are also recorded. The key assumptions relating to inventory valuations are impacted by local market and economic conditions and are inherently uncertain. Due to uncertainties in the estimation process, actual results could differ from such estimates. See Note C.
Capitalized Interest	Capitalized Interest The Company capitalizes interest costs incurred to inventory during active development and construction (active inventory). Capitalized interest is charged to cost of sales as the related inventory is delivered to the buyer. During periods in which the Company’s active inventory is lower than its debt level, a portion of the interest incurred is reflected as interest expense in the period incurred. During fiscal 2022, 2021 and 2020, the Company’s active inventory exceeded its debt level, and all interest incurred was capitalized to inventory. See Note E.
Land Option Deposits and Pre-Acquisition Costs	Land and Lot Purchase Contracts The Company enters into land and lot purchase contracts to acquire land or lots for the construction of homes. Under these contracts, the Company will fund a stated deposit in consideration for the right, but not the obligation, to purchase land or lots at a future point in time with predetermined terms. Under the terms of many of the purchase contracts, the deposits are not refundable in the event the Company elects to terminate the contract. Land purchase contract deposits and capitalized pre-acquisition costs are expensed to cost of sales when the Company believes it is probable that it will not acquire the property under contract and will not be able to recover these costs through other means. See Notes C and L.
Variable Interests	Variable Interests Land purchase contracts can result in the creation of a variable interest in the entity holding the land parcel under contract. There was one variable interest entity consolidated for $64.3 million in the Company’s balance sheet at September 30, 2022 because the Company determined it controlled the activities that most significantly impacted the variable interest entity’s economic performance. There were no variable interest entities consolidated in the Company’s balance sheet at September 30, 2021. The maximum exposure to losses related to the Company’s unconsolidated variable interest entities is limited to the amounts of the Company’s related deposits. At September 30, 2022 and 2021, the deposits related to these contracts totaled $1.5 billion and $870.2 million, respectively, and are included in other assets in the consolidated balance sheets.
Property and Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Repairs and maintenance costs are expensed as incurred. Depreciation generally is recorded using the straight-line method over the estimated useful life of the asset. The depreciable life of model home furniture is 2 years, depreciable lives of other furniture and equipment typically range from 2 to 5 years, and depreciable lives of buildings and improvements typically range from 5 to 30 years. See Note F.
Business Acquisitions	Business Acquisitions The Company accounts for acquisitions of businesses by allocating the purchase price of the business to the various assets acquired and liabilities assumed at their respective fair values. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill. Significant judgment is often required in estimating the fair value of assets acquired, particularly intangible assets. These estimates and assumptions are based on historical experience, information obtained from the management of the acquired companies and the Company’s estimates of significant assumptions that a market participant would use when determining fair value. While the Company believes the estimates and assumptions are reasonable, they are inherently uncertain. Unanticipated market or macroeconomic events and circumstances may occur, which could affect the accuracy or validity of the estimates and assumptions. In April 2022, the Company and Vidler Water Resources, Inc. (Vidler) entered into a definitive merger agreement pursuant to which the Company would acquire all of the outstanding shares of Vidler for $15.75 per share in an all-cash transaction. Under the terms of the merger agreement, in May 2022, the Company completed a tender offer and acquired all of the outstanding shares for a total purchase price of $290.5 million. There was no goodwill recorded as a result of this transaction. The Company’s allocation of the purchase price to the assets, liabilities and noncontrolling interest acquired is as follows (in millions): Cash and cash equivalents $ 19.0 Deferred income taxes, net of valuation allowance of $15.8 million 14.8 Water rights and other water-related assets (1) 280.1 Total assets 313.9 Other liabilities 5.4 Total liabilities 5.4 Noncontrolling interest 18.0 Net assets acquired $ 290.5 _____________________________________ (1) Water rights and other water-related assets were measured at fair value using Level 3 inputs and are included in other assets in the Company’s consolidated financial statements.
Goodwill	Goodwill The Company records goodwill associated with its acquisitions of businesses when the purchase price of the business exceeds the fair value of the identifiable net assets acquired. Goodwill balances are evaluated for potential impairment on at least an annual basis by performing a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of an operating segment with goodwill is less than its carrying amount. If the qualitative assessment indicates that additional impairment testing is required, then a quantitative assessment is performed to determine the operating segment’s fair value. The estimated fair value is determined by discounting the future cash flows of the operating segment to present value. If the carrying value of the operating segment exceeds its fair value, the Company records a goodwill impairment by the amount that an operating segment’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. As a result of the qualitative assessments performed in fiscal 2022, 2021 and 2020, no impairment charges were indicated or recorded. The Company’s goodwill balances by reporting segment were as follows: September 30, 2022 2021 (In millions) Northwest $ 2.2 $ 2.2 Southwest — — South Central 15.9 15.9 Southeast 6.0 6.0 East 60.5 60.5 North 49.7 49.7 Forestar 29.2 29.2 Total goodwill $ 163.5 $ 163.5
Warranty Claims	Warranty Claims The Company provides its homebuyers with a ten-year limited warranty for major defects in structural elements such as framing components and foundation systems, a two-year limited warranty on major mechanical systems and a one-year limited warranty on other construction components. Since the Company subcontracts its construction work to subcontractors who typically provide it with an indemnity and a certificate of insurance prior to receiving payments for their work, claims relating to workmanship and materials are generally the primary responsibility of the subcontractors. Warranty liabilities have been established by charging cost of sales for each home delivered. The amounts charged are based on management’s estimate of the warranty-related costs expected to be incurred in the future. The Company’s warranty liability is based upon historical warranty cost experience in each market in which it operates and is adjusted to reflect qualitative risks associated with the types of homes built and the geographic areas in which they are built. See Note L.
Legal Claims and Insurance	Legal Claims and Insurance The Company records expenses and liabilities for legal claims related to construction defect matters, personal injury claims, employment matters, land development issues, contract disputes and other matters. The amounts recorded for these contingencies are based on the estimated costs of pending claims and the estimated costs of anticipated future claims related to previously closed homes. The Company estimates and records receivables under its applicable insurance policies for these legal claims when recovery is probable. However, because the self-insured retentions under these policies are significant, the Company anticipates it will largely be self-insured. Additionally, the Company may have the ability to recover a portion of its losses from its subcontractors and their insurance carriers when the Company has been named as an additional insured on their insurance policies. See Note L.
Advertising Costs	Advertising Costs The Company expenses advertising costs as incurred. Advertising expense was approximately $41.7 million, $36.1 million and $41.7 million in fiscal 2022, 2021 and 2020, respectively.
Income Taxes	Income Taxes The Company’s income tax expense is calculated using the asset and liability method, under which deferred tax assets and liabilities are recognized based on the future tax consequences attributable to temporary differences between the financial statement amounts of assets and liabilities and their respective tax bases and attributable to net operating losses and tax credit carryforwards. When assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. The realization of deferred tax assets is dependent upon the generation of sufficient taxable income in future periods and in the jurisdictions in which those temporary differences become deductible. The Company records a valuation allowance when it determines it is more likely than not that a portion of the deferred tax assets will not be realized. The accounting for deferred taxes is based upon estimates of future results. Differences between the anticipated and actual outcomes of these future results could have a material impact on the Company’s consolidated results of operations or financial position. Also, changes in existing federal and state tax laws and tax rates could affect future tax results and the valuation of the Company’s deferred tax assets and liabilities. See Note H. Interest and penalties related to unrecognized tax benefits are recognized in the financial statements as a component of income tax expense. Significant judgment is required to evaluate uncertain tax positions. The Company evaluates its uncertain tax positions on a quarterly basis. The evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in increases or decreases in the Company’s income tax expense in the period in which the change is made. The Company’s unrecognized tax benefits totaled $2.9 million at both September 30, 2022 and 2021.
Earnings Per Share	Earnings Per Share Basic earnings per share is based on the weighted average number of shares of common stock outstanding during each year. Diluted earnings per share is based on the weighted average number of shares of common stock and dilutive securities outstanding during each year. See Note I.
Stock-Based Compensation	Stock-Based Compensation The Company’s stockholders formally authorize shares of its common stock to be available for future grants of stock-based compensation awards. From time to time, the Compensation Committee of the Company’s Board of Directors authorizes the grant of stock-based compensation to its employees and directors from these available shares. At September 30, 2022, the outstanding stock-based compensation awards include stock options and restricted stock units. Grants of restricted stock units vest over a certain number of years as determined by the Compensation Committee of the Board of Directors. Restricted stock units outstanding at September 30, 2022 have a remaining vesting period up to 4.5 years. Stock options are granted at exercise prices which equal the market value of the Company’s common stock at the date of the grant. All stock options outstanding at September 30, 2022 have vested and expire 10 years after the dates on which they were granted. The compensation expense for stock-based awards is based on the fair value of the award and is recognized on a straight-line basis over the remaining vesting period. The fair values of restricted stock units are based on the Company’s stock price on the date of grant. The fair values of stock options granted are calculated on the date of grant using a Black-Scholes option pricing model. Determining the fair value of stock options requires judgment in developing assumptions and involves a number of estimates. These estimates include, but are not limited to, the expected stock price volatility over the term of the awards, the expected dividend yield and expected stock option exercise behavior. See Note K.
Fair Value Measurements	Fair Value Measurements The Financial Accounting Standards Board’s (FASB) authoritative guidance for fair value measurements establishes a three-level hierarchy based upon the inputs to the valuation model of an asset or liability. When available, the Company uses quoted market prices in active markets to determine fair value. The Company considers the principal market and nonperformance risk associated with the Company’s counterparties when determining the fair value measurements, if applicable. Fair value measurements are used for the Company’s mortgage loans held for sale, mortgage servicing rights, interest rate lock commitments and other derivative instruments on a recurring basis and are used for inventories, other mortgage loans, rental properties and real estate owned on a nonrecurring basis, when events and circumstances indicate that the carrying value is not recoverable. See Note N.
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Pending Accounting Standards In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform,” which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (LIBOR) or by another reference rate expected to be discontinued. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform - Scope,” which clarified the scope and application of the original guidance. The Company will adopt these standards when LIBOR is discontinued and does not expect them to have a material impact on its consolidated financial statements or related disclosures. In October 2021, the FASB issued ASU 2021-08, which requires application of ASC 606, “Revenue from Contracts with Customers,” to recognize and measure contract assets and liabilities from contracts with customers acquired in a business combination. ASU 2021-08 creates an exception to the general recognition and measurement principle in ASC 805 and will result in recognition of contract assets and contract liabilities consistent with those recorded by the acquiree immediately before the acquisition date. The guidance is effective for the Company beginning October 1, 2023, with early adoption permitted. The Company is currently evaluating the impact of this guidance, and it is not expected to have a material impact on its consolidated financial position, results of operations or cash flows.

Fair Value Disclosures [Abstract]
Fair value measurements of assets and liabilities on a recurring basis	The following tables summarize the Company’s assets and liabilities measured at fair value on a recurring basis at September 30, 2022 and 2021, and the changes in the fair value of the Level 3 assets during fiscal 2022 and 2021. Fair Value at September 30, 2022 Balance Sheet Location Level 1 Level 2 Level 3 Total (In millions) Mortgage loans held for sale (1) Mortgage loans held for sale $ — $ 2,356.1 $ 14.1 $ 2,370.2 Mortgage servicing rights (2) Other assets — — 10.6 10.6 Derivatives not designated as hedging instruments (3): Interest rate lock commitments (4) Other assets and other liabilities — (135.8) — (135.8) Mortgage hedging instruments and commitments (5) Other assets and other liabilities — 317.8 — 317.8 Fair Value at September 30, 2021 Balance Sheet Location Level 1 Level 2 Level 3 Total (In millions) Mortgage loans held for sale (1) Mortgage loans held for sale $ — $ 2,009.4 $ 11.7 $ 2,021.1 Mortgage servicing rights (2) Other assets — — 4.1 4.1 Derivatives not designated as hedging instruments (3): Interest rate lock commitments (4) Other assets and other liabilities — 17.2 — 17.2 Mortgage hedging instruments and commitments Other assets — 8.5 — 8.5 Level 3 Assets at Fair Value for the Year Ended September 30, 2022 Balance at Net realized and unrealized gains (losses) Purchases / Originations Sales and Settlements Principal Reductions Net transfers to (out of) Level 3 Balance at (In millions) Mortgage loans held for sale (1) $ 11.7 $ (0.7) $ — $ (3.9) $ — $ 7.0 $ 14.1 Mortgage servicing rights (2) 4.1 (1.2) 35.3 (27.6) — — 10.6 Level 3 Assets at Fair Value for the Year Ended September 30, 2021 Balance at Net realized and unrealized gains (losses) Purchases / Originations Sales and Settlements Principal Reductions Net transfers to (out of) Level 3 Balance at (In millions) Debt securities collateralized by residential real estate $ 3.9 $ — $ — $ (3.9) $ — $ — $ — Mortgage loans held for sale (1) 15.1 0.3 — (3.3) — (0.4) 11.7 Mortgage servicing rights (2) 17.1 (0.2) 24.7 (37.5) — — 4.1 ___________________________________________ (1) The Company typically elects the fair value option upon origination for mortgage loans held for sale. Interest income earned on mortgage loans held for sale is based on contractual interest rates and included in other income. Mortgage loans held for sale valued using Level 3 inputs at September 30, 2022 and 2021 include $14.1 million and $11.7 million, respectively, of loans for which the Company elected the fair value option upon origination and did not sell into the secondary market. Mortgage loans held for sale totaling $7.0 million were transferred to Level 3 during fiscal 2022 due to significant unobservable inputs used in determining the fair value of these loans. The fair value of these mortgage loans held for sale is generally calculated considering pricing in the secondary market and adjusted for the value of the underlying collateral, including interest rate risk, liquidity risk and prepayment risk. The Company plans to sell these loans as market conditions permit. Mortgage loans totaling $0.4 million were transferred to Level 2 during fiscal 2021 because their fair value was based on actual quoted prices related to the pending sale of those loans in the secondary market. (2) Although the majority of the Company’s mortgage loans are sold on a servicing-released basis, when the servicing rights are retained, the Company records them at fair value using third-party valuations. The valuation at the time the servicing asset is retained is reflected in the purchases/originations column with subsequent changes in value classified as realized and unrealized gains (losses). The key assumptions used in the valuation, which are generally unobservable inputs, are mortgage prepayment rates, discount rates and delinquency rates, which were 12%, 11% and 8%, respectively, at September 30, 2022. (3) Fair value measurements of these derivatives represent changes in fair value, as calculated by reference to quoted prices for similar assets, and are reflected in the balance sheet as other assets or accrued expenses and other liabilities. Changes in the fair value of these derivatives are included in revenues in the consolidated statements of operations. The net fair value change in fiscal 2022 and 2021 recognized in revenues in the consolidated statements of operations was not significant. (4) The fair value of interest rate lock commitments at September 30, 2022 reflects $47.7 million of servicing release premiums in other assets and a change in fair value of $183.5 million in other liabilities. The fair value of interest rate lock commitments at September 30, 2021 reflects $17.9 million of servicing release premiums in other assets and a change in fair value of $0.7 million in other liabilities. (5) The fair value of mortgage hedging instruments and commitments at September 30, 2022 reflects a $330.2 million change in fair value in other assets and a $12.4 million change in fair value in other liabilities.
Fair value measurements of assets on a non-recurring basis	The following table summarizes the Company’s assets measured at fair value on a nonrecurring basis at September 30, 2022 and 2021. Fair Value at September 30, Balance Sheet Location 2022 2021 Level 2 Level 3 Level 2 Level 3 (In millions) Mortgage loans held for sale (1) (2) Mortgage loans held for sale $ — $ 15.8 $ — $ 3.8 Other mortgage loans (1) (3) Other assets — 1.5 — 1.3 ______________________ (1) The fair values included in the table above represent only those assets whose carrying values were adjusted to fair value as a result of impairment in the respective period and were held at the end of the period. (2) These mortgage loans have some degree of impairment affecting their marketability and are valued at the lower of carrying value or fair value. When available, quoted prices in the secondary market are used to determine fair value (Level 2); otherwise, a cash flow valuation model is used to determine fair value (Level 3).
Fair value of financial assets and liabilities	For the financial assets and liabilities that the Company does not reflect at fair value, the following tables present both their respective carrying value and fair value at September 30, 2022 and 2021. Carrying Value Fair Value at September 30, 2022 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (1) $ 2,540.5 $ 2,540.5 $ — $ — $ 2,540.5 Restricted cash (1) 32.4 32.4 — — 32.4 Notes payable (2) (3) 6,066.9 — 3,121.7 2,587.6 5,709.3 Carrying Value Fair Value at September 30, 2021 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (1) $ 3,210.4 $ 3,210.4 $ — $ — $ 3,210.4 Restricted cash (1) 26.8 26.8 — — 26.8 Notes payable (2) (3) 5,412.4 — 3,950.9 1,589.3 5,540.2 ______________ (1) The fair values of cash, cash equivalents and restricted cash approximate their carrying values due to their short-term nature and are classified as Level 1 within the fair value hierarchy. (2) The fair value of the senior notes is determined based on quoted prices, which is classified as Level 2 within the fair value hierarchy. (3) The fair values of other secured notes and borrowings on the revolving credit facility and the mortgage repurchase facility approximate carrying value due to their short-term nature or floating interest rate terms, as applicable, and are classified as Level 3 within the fair value hierarchy.
