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 64% controlling interest in Forestar Group Inc. (Forestar) and therefore is required to consolidate 100% of Forestar within its consolidated financial statements, and the 36% 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, 2020, 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, 2020. Reclassifications During the third quarter of fiscal 2021, the Company changed the presentation of its single and multi-family rental operations in its consolidated financial statements. Bulk sales of rental properties are now presented as revenues and cost of sales, rental assets previously recorded as property and equipment have been reclassified to inventory, and related cash flows for the single and multi-family rental operations are now included in operating activities. Prior to the third quarter of fiscal 2021, bulk sales of rental properties were presented on a net basis as a gain on sale of assets, and the majority of the cash flow activities were included in investing activities. This change in presentation was implemented as a result of the Company’s change in strategic focus during the third quarter of fiscal 2021, which included increased levels of activity in the current quarter and plans for future investment in the Company’s single and multi-family rental operations. This presentation was effected on a prospective basis beginning in the third quarter of fiscal 2021. 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 and nine months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2021 or subsequent periods. Business Acquisition In October 2020, the Company acquired the homebuilding operations of Braselton Homes in Corpus Christi, Texas for approximately $23.0 million in cash. The assets acquired included approximately 90 homes in inventory, 95 lots and control of approximately 840 additional lots through purchase contracts. The Company also acquired a sales order backlog of approximately 125 homes. Pending Accounting Standards In December 2019, the Financial Accounting Standards Board (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 or cash flows. 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.

Segment Information

	Jun. 30, 2021
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 96 markets across 30 states. The Company’s operating segments are its 55 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 lot 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, Kentucky, 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. During fiscal 2020, the Company began constructing and leasing homes as income-producing single-family rental communities. After a rental community is constructed and achieves a stabilized level of leased occupancy, the Company generally markets the community for a bulk sale of homes. These operations are reported in the Company’s homebuilding segment. During the third quarter of fiscal 2021, the Company sold a single-family rental community for $23.1 million in revenues and $11.4 million of gross profit. In the first quarter of fiscal 2021, the Company sold a single-family rental community for $31.8 million and recorded a gain on sale of $14.0 million. At June 30, 2021, the Company’s homebuilding inventory included $303.1 million of assets related to 44 single-family rental communities compared to $87.2 million of assets included in property and equipment related to 10 single-family rental communities at September 30, 2020. At June 30, 2021, the Company’s single-family rental properties included 2,340 homes and finished lots, of which 680 homes were completed, compared to 740 homes and finished lots, of which 440 homes were completed at September 30, 2020. The Forestar segment is a residential lot development company with operations in 55 markets across 22 states. Forestar has made significant investments in land acquisition and development to expand its business across the United States. 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 majority of the related servicing rights to third-party purchasers. In addition to its homebuilding, Forestar and financial services operations, the Company engages in other business activities through its subsidiaries. The Company conducts insurance-related operations, constructs, owns and sells income-producing multi-family rental properties, owns non-residential real estate including ranch land and improvements and owns and operates oil and gas related assets. The results of these operations are immaterial for separate reporting and therefore are grouped together and presented as other. The Company’s multi-family rental operations develop, construct, lease, own and sell multi-family rental properties, which are typically marketed for sale after achieving a stabilized level of leased occupancy. At June 30, 2021, the Company had eleven multi-family rental projects under active construction and four projects that were substantially complete and in the lease-up phase.

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 LIBOR plus an applicable margin, as defined in the credit agreement governing the facility. The maturity date of the facility was extended to April 20, 2026. At June 30, 2021, there were no borrowings outstanding and $159.3 million of letters of credit issued under the revolving credit facility, resulting in available capacity of $2.03 billion. 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 June 30, 2021, 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.

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. All of the $500 million authorization was remaining at June 30, 2021. Forestar: In April 2021, Forestar’s senior unsecured revolving credit facility was amended to increase its capacity to $410 million 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 revolving credit commitment.

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 June 30, 2021, Forestar was in compliance with all of the covenants, limitations and restrictions of its revolving credit facility. In April 2021, Forestar issued $400 million principal amount of 3.85% senior notes that mature May 15, 2026 with interest payable semi-annually.

The capacity of the facility can also be increased to $1.8 billion, subject to the availability of additional commitments. Through additional commitments, the total capacity of the facility was temporarily increased to $1.6 billion effective June 11, 2021 through November 4, 2021. During this period, the capacity increases, without requiring additional commitments, to $1.8 billion for approximately 30 days at the end of the third quarter and for 45 days at fiscal year end. The maturity date of the facility is February 18, 2022.

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 nine months of fiscal 2021 and fiscal 2020, 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 and nine months ended June 30, 2021 and 2020: Three Months Ended Nine Months Ended 2021 2020 2021 2020 (In millions) Capitalized interest, beginning of period $ 218.6 $ 200.5 $ 207.7 $ 180.1 Interest incurred (1) 37.7 38.0 116.0 113.3 Interest charged to cost of sales (35.4) (32.8) (102.8) (87.7) Capitalized interest, end of period $ 220.9 $ 205.7 $ 220.9 $ 205.7 __________________ (1) Interest incurred includes interest on the Company's mortgage repurchase facility of $4.7 million and $13.0 million in the three and nine months ended June 30, 2021, respectively, and $4.3 million and $14.0 million in the same periods of fiscal 2020. Also included in interest incurred is Forestar interest of $10.3 million and $33.3 million in the three and nine months ended June 30, 2021, respectively, and $11.4 million and $29.8 million in the same periods of fiscal 2020.

SEC Schedule, 12-29, Real Estate Companies, Investment in Mortgage Loans on Real Estate [Abstract]
MORTGAGE LOANS	MORTGAGE LOANS 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 June 30, 2021, mortgage loans held for sale had an aggregate carrying value of $1.64 billion and an aggregate outstanding principal balance of $1.60 billion. At September 30, 2020, mortgage loans held for sale had an aggregate carrying value of $1.53 billion and an aggregate outstanding principal balance of $1.46 billion. During the nine months ended June 30, 2021 and 2020, mortgage loans originated totaled $11.5 billion and $8.4 billion, respectively, and mortgage loans sold totaled $11.4 billion and $8.0 billion, respectively. The Company had gains on sales of loans and servicing rights of $135.4 million and $453.0 million during the three and nine months ended June 30, 2021, respectively, compared to $116.7 million and $263.7 million in the prior year periods. Net gains on sales of loans and servicing rights are included in revenues in the consolidated statements of operations. During the nine months ended June 30, 2021, approximately 55% of the Company’s mortgage loans were sold directly to the Federal National Mortgage Association (Fannie Mae) or into securities backed by the Government National Mortgage Association (Ginnie Mae), and 37% were sold to two other major financial entities. The Company also uses hedging instruments as part of a program to offer below market interest rate financing to its homebuyers. At June 30, 2021 and September 30, 2020, the Company had mortgage-backed securities (MBS) totaling $862.4 million and $1.1 billion, respectively, that did not yet have interest rate lock commitments or closed loans created or assigned and recorded a liability of $1.9 million and $5.3 million, respectively, for the fair value of such MBS position.

INCOME TAXES	INCOME TAXES The Company’s income tax expense for the three and nine months ended June 30, 2021 was $299.1 million and $784.1 million, respectively, compared to $149.5 million and $377.6 million in the prior year periods. The effective tax rate was 21.1% and 21.6% for the three and nine months ended June 30, 2021 compared to 19.1% and 19.6% in the prior year periods. The effective tax rates for all periods include an expense for state income taxes and tax benefits related to stock-based compensation and the federal energy efficient homes tax credit. For the three and nine months ended June 30, 2020, the fiscal 2020 retroactive reinstatement of the federal energy efficient homes tax credit reduced the effective tax rate by 3.1% and 2.8%, respectively. For the three and nine months ended June 30, 2021, a change in the estimate of homes qualifying for the fiscal 2020 energy efficient tax credit and the retroactive extension of the energy efficient tax credit reduced the effective tax rate by 1.9% and 0.9%, respectively. The Company’s deferred tax assets, net of deferred tax liabilities, were $154.4 million at June 30, 2021 compared to $152.4 million at September 30, 2020. The Company has a valuation allowance of $7.3 million and $7.5 million at June 30, 2021 and September 30, 2020, respectively, 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.

STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY D.R. Horton has an automatically effective universal shelf registration statement, filed with the SEC in August 2018, registering debt and equity securities that it may issue from time to time in amounts to be determined. Forestar also has an effective shelf registration statement filed with the SEC in September 2018, registering $500 million of equity securities, of which $100 million was reserved for sales under its at-the-market equity offering program that became effective in August 2020. During the nine months ended June 30, 2021, Forestar issued 1.4 million shares of common stock under its at-the-market equity offering program for proceeds of $32.6 million, net of commissions and other issuance costs. At June 30, 2021, $361.0 million remained available for issuance under Forestar’s shelf registration statement, of which $66.7 million is reserved for sales under its at-the-market equity offering program.

Compensation Related Costs [Abstract]
Compensation Related Costs, General	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 2020, the Company granted 360,000 performance-based RSU equity awards to its executive officers. These awards vest at the end of a three During the nine months ended June 30, 2021, the Company granted approximately 860,000 time-based RSUs to 1,030 recipients, including executive officers, other key employees and non-management directors. The weighted average grant date fair value of these equity awards was $83.13 per unit, and they vest annually in equal installments over periods of three to five years. Compensation expense related to these grants was $4.0 million and $9.5 million in the three and nine months ended June 30, 2021, respectively. Compensation expense in the nine month period included $4.8 million of expense recognized for employees that were retirement eligible on the date of grant. Total stock-based compensation expense related to the Company’s performance-based and time-based restricted stock units was $21.4 million and $66.6 million during the three and nine months ended June 30, 2021, respectively, compared to $20.4 million and $56.6 million during the three and nine months ended June 30, 2020.

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 and nine months ended June 30, 2021 and 2020 were as follows: Three Months Ended Nine Months Ended 2021 2020 2021 2020 (In millions) Warranty liability, beginning of period $ 340.7 $ 262.7 $ 310.2 $ 247.3 Warranties issued 41.8 29.4 111.5 75.1 Changes in liability for pre-existing warranties 1.7 5.7 5.4 14.0 Settlements made (22.7) (16.5) (65.6) (55.1) Warranty liability, end of period $ 361.5 $ 281.3 $ 361.5 $ 281.3 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 $543.1 million and $473.8 million at June 30, 2021 and September 30, 2020, 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 June 30, 2021 and September 30, 2020. Expenses related to the Company’s legal contingencies were $46.2 million and $41.1 million in the nine months ended June 30, 2021 and 2020, respectively. Changes in the Company’s legal claims reserves during the nine months ended June 30, 2021 and 2020 were as follows: Nine Months Ended 2021 2020 (In millions) Reserves for legal claims, beginning of period $ 473.8 $ 434.7 Increase in reserves 88.8 57.1 Payments (19.5) (30.5) Reserves for legal claims, end of period $ 543.1 $ 461.3 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. 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 $98.1 million, $81.2 million and $82.4 million at June 30, 2021, September 30, 2020 and June 30, 2020, 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. 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 June 30, 2021, the Company’s homebuilding segment had total deposits of $999.8 million, consisting of cash deposits of $918.9 million and promissory notes and surety bonds of $80.9 million, related to contracts to purchase land and lots with a total remaining purchase price of approximately $15.0 billion. The majority of land and lots under contract are currently expected to be purchased within three years. Of these amounts, $152.7 million of the deposits related to contracts with Forestar to purchase land and lots with a remaining purchase price of $1.6 billion. A limited number of the homebuilding land and lot purchase contracts at June 30, 2021, representing $136.9 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 $136.9 million remaining purchase price subject to specific performance provisions, $67.8 million related to contracts between the homebuilding segment and Forestar. During the three and nine months ended June 30, 2021, Forestar reimbursed the homebuilding segment $3.5 million and $27.7 million, respectively, for previously paid earnest money and $14.9 million and $43.1 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. During the three and nine months ended June 30, 2020, Forestar reimbursed the homebuilding segment $7.0 million and $23.2 million, respectively, for previously paid earnest money and $12.9 million and $26.2 million, respectively, for pre-acquisition and other due diligence costs. Other Commitments At June 30, 2021, the Company had outstanding surety bonds of $2.1 billion and letters of credit of $219.5 million to secure performance under various contracts. Of the total letters of credit, $159.3 million were issued under the homebuilding revolving credit facility, and $60.2 million were issued under Forestar’s revolving credit facility.

Changes in the fair value of the Level 3 assets during the nine months ended June 30, 2021 and 2020 were not material.

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 June 30, 2021 and September 30, 2020 included $9.4 million and $15.1 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. (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 Level 3 valuations unless specific investor bids are available during the subsequent sale process resulting in a Level 2 valuation. The key assumptions used in third-party Level 3 valuations, which are generally unobservable inputs, are mortgage prepayment rates, discount rates and delinquency rates, which were 10%, 11% and 6%, respectively, at June 30, 2021 and 13%, 11% and 5%, respectively, at September 30, 2020. (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 for the three and nine months ended June 30, 2021 and 2020 recognized in revenues in the consolidated statements of operations was not significant. The following table summarizes the Company’s assets measured at fair value on a nonrecurring basis at June 30, 2021 and September 30, 2020: Fair Value at Fair Value at Balance Sheet Location Level 2 Level 3 Level 2 Level 3 (In millions) Mortgage loans held for sale (1) (2) Mortgage loans held for sale $ 0.6 $ 0.6 $ 1.5 $ 2.2 Other mortgage loans (1) (3) Other assets 2.7 1.3 0.6 2.0 Real estate owned (1) (3) Other assets — 0.2 — — ___________________ (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). (3) The fair values of other mortgage loans and real estate owned were 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 June 30, 2021 and September 30, 2020: Carrying Value Fair Value at June 30, 2021 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (1) $ 1,942.7 $ 1,942.7 $ — $ — $ 1,942.7 Restricted cash (1) 26.4 26.4 — — 26.4 Notes payable (2) (3) 4,416.3 — 3,373.9 1,188.9 4,562.8 Carrying Value Fair Value at September 30, 2020 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (1) $ 3,018.5 $ 3,018.5 $ — $ — $ 3,018.5 Restricted cash (1) 21.6 21.6 — — 21.6 Notes payable (2) (3) 4,283.3 — 3,285.5 1,203.7 4,489.2 ___________________ (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 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.

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 64% controlling interest in Forestar Group Inc. (Forestar) and therefore is required to consolidate 100% of Forestar within its consolidated financial statements, and the 36% 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, 2020, 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, 2020. Reclassifications During the third quarter of fiscal 2021, the Company changed the presentation of its single and multi-family rental operations in its consolidated financial statements. Bulk sales of rental properties are now presented as revenues and cost of sales, rental assets previously recorded as property and equipment have been reclassified to inventory, and related cash flows for the single and multi-family rental operations are now included in operating activities. Prior to the third quarter of fiscal 2021, bulk sales of rental properties were presented on a net basis as a gain on sale of assets, and the majority of the cash flow activities were included in investing activities. This change in presentation was implemented as a result of the Company’s change in strategic focus during the third quarter of fiscal 2021, which included increased levels of activity in the current quarter and plans for future investment in the Company’s single and multi-family rental operations. This presentation was effected on a prospective basis beginning in the third quarter of fiscal 2021.
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.
Business Combinations Policy	Business Acquisition In October 2020, the Company acquired the homebuilding operations of Braselton Homes in Corpus Christi, Texas for approximately $23.0 million in cash. The assets acquired included approximately 90 homes in inventory, 95 lots and control of approximately 840 additional lots through purchase contracts.

Recent Accounting Pronouncements	Pending Accounting Standards In December 2019, the Financial Accounting Standards Board (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 or cash flows. 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.
Reclassifications	Reclassifications During the third quarter of fiscal 2021, the Company changed the presentation of its single and multi-family rental operations in its consolidated financial statements. Bulk sales of rental properties are now presented as revenues and cost of sales, rental assets previously recorded as property and equipment have been reclassified to inventory, and related cash flows for the single and multi-family rental operations are now included in operating activities. Prior to the third quarter of fiscal 2021, bulk sales of rental properties were presented on a net basis as a gain on sale of assets, and the majority of the cash flow activities were included in investing activities. This change in presentation was implemented as a result of the Company’s change in strategic focus during the third quarter of fiscal 2021, which included increased levels of activity in the current quarter and plans for future investment in the Company’s single and multi-family rental operations. This presentation was effected on a prospective basis beginning in the third quarter of fiscal 2021.

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 June 30, 2021 and September 30, 2020. Changes in the fair value of the Level 3 assets during the nine months ended June 30, 2021 and 2020 were not material. Fair Value at June 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 $ — $ 1,624.7 $ 9.4 $ 1,634.1 Mortgage servicing rights (2) Other assets — 13.9 0.3 14.2 Derivatives not designated as hedging instruments (3): Interest rate lock commitments Other assets — 22.1 — 22.1 Forward sales of mortgage-backed securities Other liabilities — (16.9) — (16.9) Fair Value at September 30, 2020 Balance Sheet Location Level 1 Level 2 Level 3 Total (In millions) Debt securities collateralized by residential real estate Other assets $ — $ — $ 3.9 $ 3.9 Mortgage loans held for sale (1) Mortgage loans held for sale — 1,503.2 15.1 1,518.3 Mortgage servicing rights (2) Other assets — — 17.1 17.1 Derivatives not designated as hedging instruments (3): Interest rate lock commitments Other assets — 31.3 — 31.3 Forward sales of mortgage-backed securities Other liabilities — (16.2) — (16.2) ___________________ (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 June 30, 2021 and September 30, 2020 included $9.4 million and $15.1 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. (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 Level 3 valuations unless specific investor bids are available during the subsequent sale process resulting in a Level 2 valuation. The key assumptions used in third-party Level 3 valuations, which are generally unobservable inputs, are mortgage prepayment rates, discount rates and delinquency rates, which were 10%, 11% and 6%, respectively, at June 30, 2021 and 13%, 11% and 5%, respectively, at September 30, 2020. (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 for the three and nine months ended June 30, 2021 and 2020 recognized in revenues in the consolidated statements of operations was not significant.
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 June 30, 2021 and September 30, 2020: Fair Value at Fair Value at Balance Sheet Location Level 2 Level 3 Level 2 Level 3 (In millions) Mortgage loans held for sale (1) (2) Mortgage loans held for sale $ 0.6 $ 0.6 $ 1.5 $ 2.2 Other mortgage loans (1) (3) Other assets 2.7 1.3 0.6 2.0 Real estate owned (1) (3) Other assets — 0.2 — — ___________________ (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). (3) The fair values of other mortgage loans and real estate owned were determined based on the value of the underlying collateral.
Carrying values and fair values of financial assets and liabilities not reflected at fair value	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 June 30, 2021 and September 30, 2020: Carrying Value Fair Value at June 30, 2021 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (1) $ 1,942.7 $ 1,942.7 $ — $ — $ 1,942.7 Restricted cash (1) 26.4 26.4 — — 26.4 Notes payable (2) (3) 4,416.3 — 3,373.9 1,188.9 4,562.8 Carrying Value Fair Value at September 30, 2020 Level 1 Level 2 Level 3 Total (In millions) Cash and cash equivalents (1) $ 3,018.5 $ 3,018.5 $ — $ — $ 3,018.5 Restricted cash (1) 21.6 21.6 — — 21.6 Notes payable (2) (3) 4,283.3 — 3,285.5 1,203.7 4,489.2 ___________________ (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 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.
