Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited, consolidated financial statements include the accounts of D.R. Horton, Inc. and all of its 100% 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. The Company owns a 65% controlling interest in Forestar Group Inc. (Forestar) and therefore is required to consolidate 100% of Forestar within its consolidated financial statements, and the 35% interest the Company does not own is accounted for as noncontrolling interests. All intercompany accounts, transactions and balances have been eliminated in consolidation. The financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, these financial statements reflect all adjustments considered necessary to fairly state the results for the interim periods shown, including normal recurring accruals and other items. These financial statements, including the consolidated balance sheet as of September 30, 2019 , which was derived from audited financial statements, do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2019 . Reclassifications Certain prior period amounts have been reclassified to conform to the current year presentation. At December 31, 2019 , the Company reclassified its single-family rental properties from other assets to property and equipment in its homebuilding segment. Reclassification of the prior period amount resulted in a $37.0 million decrease in other assets with a corresponding increase in property and equipment at September 30, 2019 . This reclassification had no effect on the Company’s consolidated financial position or results of operations. 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. Seasonality Historically, the homebuilding industry has experienced seasonal fluctuations; therefore, the operating results for the three months ended December 31, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2020 or subsequent periods. Adoption of New Accounting Standard In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, “Leases,” which requires that lease assets and liabilities be recognized on the balance sheet and that key information about leasing arrangements be disclosed. The guidance was effective for the Company beginning October 1, 2019 and did not have a material impact on its consolidated financial position, results of operations or cash flows. As a result of the adoption of this standard on October 1, 2019, the Company recorded right of use assets of $39.0 million and lease liabilities of $40.3 million . Lease right of use assets are included in other assets and lease liabilities are included in accrued expenses and other liabilities in the consolidated balance sheet. Pending Accounting Standards In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses,” which replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information in determining credit loss estimates. The guidance is effective for the Company beginning October 1, 2020 and is not expected to have a material impact on its consolidated financial position, results of operations or cash flows. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other,” which simplifies the measurement of goodwill impairment by removing the second step of the goodwill impairment test and requires the determination of the fair value of individual assets and liabilities of a reporting unit. Under the new guidance, goodwill impairment is measured as the amount by which a reporting unit’s carrying amount exceeds its fair value with the loss recognized limited to the total amount of goodwill allocated to the reporting unit. The guidance is effective for the Company beginning October 1, 2020 and is not expected to have a material impact on its consolidated financial position, results of operations or cash flows. In December 2019, the FASB issued ASU 2019-12 related to simplifying the accounting for income taxes. The guidance is effective for the Company beginning October 1, 2021, although early adoption is 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 and cash flows.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company is a national homebuilder that is primarily engaged in the acquisition and development of land and the construction and sale of residential homes, with operations in 90 markets across 29 states. The Company’s operating segments are its 52 homebuilding divisions, its majority-owned Forestar residential lot development operations, its financial services operations and its other business activities. The Company’s reporting segments are its homebuilding reporting segments, its Forestar land development segment and its financial services segment. The homebuilding operating segments are aggregated into the following six reporting segments: East, Midwest, Southeast, South Central, Southwest and West. These reporting segments have homebuilding operations located in the following states: East: Delaware, Georgia (Savannah only), Maryland, New Jersey, North Carolina, Pennsylvania, South Carolina and Virginia Midwest: Colorado, Illinois, Indiana, Iowa, Minnesota and Ohio Southeast: Alabama, Florida, Georgia, Mississippi and Tennessee South Central: Louisiana, Oklahoma and Texas Southwest: Arizona and New Mexico West: California, Hawaii, Nevada, Oregon, Utah and Washington The Company’s homebuilding divisions design, build and sell single-family detached homes on lots they develop and on fully developed lots purchased ready for home construction. To a lesser extent, the homebuilding divisions also build and sell attached homes, such as townhomes, duplexes and triplexes. 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. The Forestar segment is a residential lot development company with operations in 51 markets across 20 states. Forestar is making significant investments in land acquisition and development to expand its business across a geographically diversified national platform. The 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. 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. In addition to its homebuilding, Forestar and financial services operations, the Company has subsidiaries that engage in other business activities. These subsidiaries conduct insurance-related operations, construct and own income-producing multi-family rental properties, own non-residential real estate including ranch land and improvements and own and operate oil and gas related assets. The operating results of these subsidiaries are immaterial for separate reporting and therefore are grouped together and presented as other. One of these subsidiaries, DHI Communities, constructs multi-family rental properties and has four projects under active construction and one project that was substantially complete at December 31, 2019 . In November 2019, DHI Communities sold a multi-family rental property for $61.5 million and recorded a gain on the sale of $31.2 million . At December 31, 2019 and September 30, 2019 , the consolidated balance sheets included $209.8 million and $204.0 million , respectively, of assets owned by DHI Communities. The accounting policies of the reporting segments are described throughout Note A included in the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2019 . Financial information relating to the Company’s reporting segments is as follows: December 31, 2019 Homebuilding Forestar (1) Financial Services Other (2) Eliminations (3) Other Adjustments (4) Consolidated (In millions) Assets Cash and cash equivalents $ 1,152.9 $ 373.3 $ 37.5 $ 19.6 $ — $ — $ 1,583.3 Restricted cash 6.6 — 5.9 0.1 — — 12.6 Inventories: Construction in progress and finished homes 5,603.3 — — — (23.2 ) — 5,580.1 Residential land and lots — developed and under development 5,192.7 1,051.4 — — (32.1 ) 2.1 6,214.1 Land held for development 66.7 15.4 — — — — 82.1 Land held for sale 22.9 — — — — — 22.9 10,885.6 1,066.8 — — (55.3 ) 2.1 11,899.2 Mortgage loans held for sale — — 1,025.1 — — — 1,025.1 Deferred income taxes, net 140.1 11.8 — — 8.2 (6.0 ) 154.1 Property and equipment, net 292.8 0.9 3.1 267.6 (1.0 ) — 563.4 Other assets 864.4 27.1 59.7 46.1 (86.1 ) 10.5 921.7 Goodwill 134.3 — — — — 29.2 163.5 $ 13,476.7 $ 1,479.9 $ 1,131.3 $ 333.4 $ (134.2 ) $ 35.8 $ 16,322.9 Liabilities Accounts payable $ 624.7 $ 19.8 $ 1.4 $ 13.4 $ — $ — $ 659.3 Accrued expenses and other liabilities 1,240.6 172.4 62.3 9.7 (94.5 ) (13.1 ) 1,377.4 Notes payable 2,470.0 462.1 850.2 — — 1.0 3,783.3 $ 4,335.3 $ 654.3 $ 913.9 $ 23.1 $ (94.5 ) $ (12.1 ) $ 5,820.0 ______________ (1) Amounts are presented on Forestar’s historical cost basis, consistent with the manner in which management evaluates segment performance.

Homebuilding: The Company has a $1.59 billion senior unsecured homebuilding revolving credit facility with an uncommitted accordion feature that could increase the size of the facility to $2.5 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 revolving credit commitment. Letters of credit issued under the facility reduce the available borrowing capacity. The interest rate on borrowings under the revolving credit facility may be based on either the Prime Rate or London Interbank Offered Rate (LIBOR) plus an applicable margin, as defined in the credit agreement governing the facility. The maturity date of the facility is October 2, 2024 . At December 31, 2019 , there were no borrowings outstanding and $141.7 million of letters of credit issued under the revolving credit facility, resulting in available capacity of approximately $1.4 billion . There were no borrowings or repayments under the facility during the three months ended December 31, 2019 . 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 indenture governing the senior notes also impose restrictions on the creation of secured debt and liens. At December 31, 2019 , 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 Securities and Exchange Commission (SEC) in August 2018 , registering debt and equity securities that the Company may issue from time to time in amounts to be determined. In October 2019 , the Company issued $500 million principal amount of 2.5% senior notes due October 15, 2024 , with interest payable semi-annually. The annual effective interest rate of these notes after giving effect to the amortization of the discount and financing costs is 2.7% . Effective July 30, 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.

Forestar: Forestar has a $380 million senior unsecured revolving credit facility with an uncommitted accordion feature that could increase the size of the facility to $570 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 revolving credit commitment. Borrowings under the revolving credit facility are subject to a borrowing base based on Forestar’s book value of its real estate assets and unrestricted cash. Letters of credit issued under the facility reduce the available borrowing capacity. At December 31, 2019 , there were no borrowings outstanding and $28.7 million of letters of credit issued under the revolving credit facility, resulting in available capacity of $351.3 million . The maturity date of the facility is October 2, 2022 , which can be extended by up to one year on up to two additional occasions, subject to the approval of lenders holding a majority of the commitments. 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. At December 31, 2019 , Forestar was in compliance with all of the covenants, limitations and restrictions of its revolving credit facility. At December 31, 2019 , the principal amount of Forestar’s 3.75% convertible senior notes was $118.9 million . Forestar intends to settle these notes in cash upon their maturity on March 1, 2020 , with any excess conversion value to be settled in shares of its common stock. At December 31, 2019 , Forestar was in compliance with all of the limitations and restrictions associated with its senior note obligations. Forestar’s revolving credit facility, its senior notes and its convertible senior notes are not guaranteed by D.R. Horton, Inc. or any of the subsidiaries that guarantee the Company’s homebuilding debt. 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 $900 million , which can be increased to $1.2 billion subject to the availability of additional commitments. In December 2019 , the Company received an additional commitment of $50 million increasing the total capacity of the facility to $950 million . The additional commitment expired on January 26, 2020 . The Company is currently in discussions with its lenders and expects to renew and extend the facility on similar terms prior to its February 21, 2020 maturity date. As of December 31, 2019 , $953.7 million of mortgage loans held for sale with a collateral value of $915.1 million were pledged under the mortgage repurchase facility.

The mortgage repurchase facility is not guaranteed by D.R. Horton, Inc. or any of the subsidiaries that guarantee the Company’s homebuilding debt. 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 December 31, 2019 , DHI Mortgage was in compliance with all of the conditions and covenants of the mortgage repurchase facility.

Interest Costs Incurred [Abstract]
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 the first three months of fiscal 2020 and 2019 , the Company’s active inventory exceeded its debt level, and all interest incurred was capitalized to inventory. The following table summarizes the Company’s interest costs incurred, capitalized and expensed during the three months ended December 31, 2019 and 2018 : Three Months Ended 2019 2018 (In millions) Capitalized interest, beginning of period $ 180.1 $ 162.7 Interest incurred (1) 37.7 31.7 Interest charged to cost of sales (25.7 ) (25.6 ) Capitalized interest, end of period $ 192.1 $ 168.8 _______________ (1) Interest incurred included interest on the Company's mortgage repurchase facility of $4.7 million and $3.3 million in the three months ended December 31, 2019 and 2018 , respectively, and Forestar interest of $8.7 million and $1.3 million , respectively.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s income tax expense for the three months ended December 31, 2019 and 2018 was $90.8 million and $89.0 million , respectively. The effective tax rate was 17.4% for the three months ended December 31, 2019 compared to 23.7% in the prior year period. The effective tax rate for the three months ended December 31, 2019 includes a tax benefit of $32.9 million from the enactment of the Taxpayer Certainty and Disaster Tax Relief Act of 2019 (the Act). The Act retroactively reinstated the federal energy efficient homes tax credit that expired on December 31, 2017 to homes closed from January 1, 2018 to December 31, 2020 . The effective tax rates for both periods include an expense for state income taxes, reduced by tax benefits related to stock-based compensation. The Company’s deferred tax assets, net of deferred tax liabilities, were $172.4 million at December 31, 2019 compared to $181.8 million at September 30, 2019 . The Company has a valuation allowance of $18.3 million at December 31, 2019 and $18.7 million at September 30, 2019 related to state deferred tax assets for net operating loss (NOL) carryforwards that are more likely than not to expire before being realized. 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 carryforwards. Any reversal of the valuation allowance in future periods will impact the Company’s effective tax rate. 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.

Compensation Related Costs [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Restricted Stock Units (RSUs) 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 awards may be based on performance (performance-based) or on service over a requisite time period (time-based). Performance-based and time-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. In November 2019 , a total of 360,000 performance-based RSU equity awards were granted to the Company’s executive officers. These awards vest at the end of a three-year performance period ending September 30, 2022 . 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; selling, general and administrative expense containment; and gross profit. The grant date fair value of these equity awards was $52.54 per unit. Compensation expense related to these grants was $2.1 million in the three months ended December 31, 2019 , 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.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES 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. 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. Changes in the Company’s warranty liability during the three months ended December 31, 2019 and 2018 were as follows: Three Months Ended 2019 2018 (In millions) Warranty liability, beginning of period $ 247.3 $ 202.0 Warranties issued 21.2 18.0 Changes in liability for pre-existing warranties 2.7 5.5 Settlements made (19.6 ) (19.9 ) Warranty liability, end of period $ 251.6 $ 205.6 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 $432.5 million and $434.7 million at December 31, 2019 and September 30, 2019 , 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 December 31, 2019 and September 30, 2019 . Expenses related to the Company’s legal contingencies were $16.6 million and $5.8 million in the three months ended December 31, 2019 and 2018 , respectively. The Company’s reserves for legal claims were $432.5 million at December 31, 2019 compared to $434.7 million at September 30, 2019 . Changes in the Company’s legal claims reserves during the three months ended December 31, 2019 and 2018 were as follows: Three Months Ended 2019 2018 (In millions) Reserves for legal claims, beginning of period $ 434.7 $ 408.1 Increase in reserves 21.1 11.6 Payments (23.3 ) (7.5 ) Reserves for legal claims, end of period $ 432.5 $ 412.2 The Company estimates and records receivables under its applicable insurance policies related to its estimated contingencies 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. 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. The Company’s receivables related to its estimates of insurance recoveries from estimated losses for pending legal claims and anticipated future claims related to previously closed homes totaled $76.9 million , $75.1 million and $57.8 million at December 31, 2019 , September 30, 2019 and December 31, 2018 , respectively, and are included in other assets in the consolidated balance sheets. 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. 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 inventory and land option charges 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. At December 31, 2019 , the Company’s homebuilding segment had total deposits of $538.5 million , consisting of cash deposits of $515.9 million and promissory notes of $22.6 million , related to contracts to purchase land and lots with a total remaining purchase price of approximately $7.6 billion . The majority of land and lots under contract are currently expected to be purchased within three years. Of these amounts, $88.8 million of the deposits related to contracts with Forestar to purchase land and lots with a remaining purchase price of $918.6 million . A limited number of the homebuilding land and lot purchase contracts at December 31, 2019 , representing $57.3 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 $57.3 million remaining purchase price subject to specific performance provisions, $12.3 million related to contracts between the homebuilding segment and Forestar. During the three months ended December 31, 2019 and 2018 , Forestar reimbursed the homebuilding segment $10.7 million and $12.1 million , respectively, for previously paid earnest money and $5.2 million and $3.0 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 December 31, 2019 , the Company had outstanding surety bonds of $1.7 billion and letters of credit of $170.4 million to secure performance under various contracts. Of the total letters of credit, $141.7 million were issued under the homebuilding revolving credit facility and $28.7 million were issued under Forestar’s revolving credit facility. At December 31, 2019 , letters of credit issued under the homebuilding revolving credit facility were cash collateralized to improve pricing terms. This unrestricted cash can be withdrawn by the Company at its discretion.

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 December 31, 2019 and September 30, 2019 include $11.8 million and $9.8 million , respectively, of loans for which the Company elected the fair value option upon origination and did not sell into the secondary market. 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. (b) 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 following table summarizes the Company’s assets measured at fair value on a nonrecurring basis at December 31, 2019 and September 30, 2019 : Fair Value at Fair Value at Balance Sheet Location Level 2 Level 3 Level 2 Level 3 (In millions) Inventory held and used (a) (b) Inventories $ — $ — $ — $ 4.5 Mortgage loans held for sale (a) (c) Mortgage loans held for sale — 3.6 — 2.7 Other mortgage loans (a) (d) Other assets — 1.1 — 1.8 ___________________ (a) 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. (b) In performing its impairment analysis of communities, discount rates ranging from 16% to 18% were used in the periods presented. (c) 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). (d) The fair values of other mortgage loans was determined based on the value of the underlying collateral. 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 December 31, 2019 and September 30, 2019 : Carrying Value Fair Value at December 31, 2019 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (a) $ 1,583.3 $ 1,583.3 $ — $ — $ 1,583.3 Restricted cash (a) 12.6 12.6 — — 12.6 Notes payable (b) (c) 3,783.3 — 3,035.1 879.1 3,914.2 Carrying Value Fair Value at September 30, 2019 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (a) $ 1,494.3 $ 1,494.3 $ — $ — $ 1,494.3 Restricted cash (a) 19.7 19.7 — — 19.7 Notes payable (b) (c) 3,399.4 — 2,533.9 991.9 3,525.8 ___________________ (a) 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. (b) The fair value of the senior notes is determined based on quoted prices, which is classified as Level 2 within the fair value hierarchy. (c) The fair values of other secured notes and borrowings on the revolving credit facilities 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.

Related Party Transaction [Line Items]
Related Party Transactions Disclosure [Text Block]	RELATED PARTY TRANSACTIONS In March 2019 , the Company assigned its rights under a land purchase contract it entered into in December 2017 to R&R Riverview LLC (R&R), an entity owned by Ryan Horton and Reagan Horton, the adult sons of Donald R. Horton, the Company’s Chairman. In March 2019 , R&R exercised its rights under the purchase contract and paid $77.5 million for 119 acres of undeveloped land in Arizona. In connection with the transaction, Donald R. Horton loaned R&R $77.5 million at a 2.55% annual interest rate and obtained a security interest in the land. Concurrent with the contract assignment to R&R, the Company entered into a land purchase contract with R&R to purchase the 119 acres for R&R’s cost plus an annualized return of 16% . In accordance with the Company’s policy on related party transactions, this transaction was reviewed and approved by a committee of the Board of Directors composed of independent directors. The Company determined that R&R was a variable interest entity, and the Company had the power through its rights in its land purchase contract with R&R to control the activities that most significantly impact the entity’s economic performance, and the Company is the primary beneficiary. Accordingly, the Company consolidated the variable interest entity in its consolidated financial statements by increasing inventory and notes payable by $77.5 million , and this amount was included in those balances at September 30, 2019. In October 2019, the Company paid R&R $84.2 million for all 119 acres of land and deconsolidated the variable interest entity from the financial statements. The purchase transaction was also reviewed and approved by a committee of the Board of Directors composed of independent directors.

Supplemental Guarantor Information [Abstract]
SUPPLEMENTAL GUARANTOR INFORMATION	SUPPLEMENTAL GUARANTOR INFORMATION All of the Company’s homebuilding senior notes and the homebuilding revolving credit facility are fully and unconditionally guaranteed, on a joint and several basis, by certain subsidiaries of D.R. Horton, Inc. (Guarantor Subsidiaries). Each of the Guarantor Subsidiaries is 100% owned, directly or indirectly, by the Company. The Company’s subsidiaries associated with the Forestar land development operation, the financial services operations and certain other subsidiaries do not guarantee the Company’s homebuilding senior notes or the homebuilding revolving credit facility (collectively, Non-Guarantor Subsidiaries). In lieu of providing separate financial statements for the Guarantor Subsidiaries, consolidating condensed financial statements are presented below. Separate financial statements and other disclosures concerning the Guarantor Subsidiaries are not presented because management has determined that they are not material to investors. The guarantees by a Guarantor Subsidiary will be automatically and unconditionally released and discharged upon: (1) the sale or other disposition of its common stock whereby it is no longer a subsidiary of the Company; (2) the sale or other disposition of all or substantially all of its assets (other than to the Company or another Guarantor); (3) its merger or consolidation with an entity other than the Company or another Guarantor; or (4) its ceasing to guarantee any of the Company’s publicly traded debt securities and ceasing to guarantee any of the Company’s obligations under the homebuilding revolving credit facility. As described in Note A, at December 31, 2019 , the Company reclassified its single-family rental properties from other assets to property and equipment in its homebuilding segment. Reclassification of prior period amounts resulted in decreases in other assets of $26.9 million and $10.1 million in the D.R. Horton, Inc. and Guarantor Subsidiaries columns, respectively, with corresponding increases in property and equipment at September 30, 2019 .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited, consolidated financial statements include the accounts of D.R. Horton, Inc. and all of its 100% 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. The Company owns a 65% controlling interest in Forestar Group Inc. (Forestar) and therefore is required to consolidate 100% of Forestar within its consolidated financial statements, and the 35% interest the Company does not own is accounted for as noncontrolling interests. All intercompany accounts, transactions and balances have been eliminated in consolidation. The financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, these financial statements reflect all adjustments considered necessary to fairly state the results for the interim periods shown, including normal recurring accruals and other items. These financial statements, including the consolidated balance sheet as of September 30, 2019 , which was derived from audited financial statements, do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2019 .
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current year presentation. At December 31, 2019 , the Company reclassified its single-family rental properties from other assets to property and equipment in its homebuilding segment. Reclassification of the prior period amount resulted in a $37.0 million decrease in other assets with a corresponding increase in property and equipment at September 30, 2019 . This reclassification had no effect on the Company’s consolidated financial position or results of operations.
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Adoption of New Accounting Standard In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, “Leases,” which requires that lease assets and liabilities be recognized on the balance sheet and that key information about leasing arrangements be disclosed. The guidance was effective for the Company beginning October 1, 2019 and did not have a material impact on its consolidated financial position, results of operations or cash flows. As a result of the adoption of this standard on October 1, 2019, the Company recorded right of use assets of $39.0 million and lease liabilities of $40.3 million . Lease right of use assets are included in other assets and lease liabilities are included in accrued expenses and other liabilities in the consolidated balance sheet.
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.
Recent Accounting Pronouncements	Pending Accounting Standards In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses,” which replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information in determining credit loss estimates. The guidance is effective for the Company beginning October 1, 2020 and is not expected to have a material impact on its consolidated financial position, results of operations or cash flows. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other,” which simplifies the measurement of goodwill impairment by removing the second step of the goodwill impairment test and requires the determination of the fair value of individual assets and liabilities of a reporting unit. Under the new guidance, goodwill impairment is measured as the amount by which a reporting unit’s carrying amount exceeds its fair value with the loss recognized limited to the total amount of goodwill allocated to the reporting unit. The guidance is effective for the Company beginning October 1, 2020 and is not expected to have a material impact on its consolidated financial position, results of operations or cash flows. In December 2019, the FASB issued ASU 2019-12 related to simplifying the accounting for income taxes. The guidance is effective for the Company beginning October 1, 2021, although early adoption is 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 and cash flows.
