Basis of Presentation

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited, consolidated financial statements include the accounts of Forestar Group Inc. (Forestar) and all of its 100% owned, majority-owned and controlled subsidiaries, which are collectively referred to as the Company unless the context otherwise requires. The Company accounts for its investment in other entities in which it has significant influence over operations and financial policies using the equity method. All intercompany accounts, transactions and balances have been eliminated in consolidation. Noncontrolling interests in consolidated pass-through entities are recognized before income taxes. The transactions included in net income in the consolidated statements of operations are the same as those that would be presented in comprehensive income. Thus, the Company's net income equates to comprehensive income. 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, 2021, 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, 2021. In October 2017, Forestar became a majority-owned subsidiary of D.R. Horton, Inc. (D.R. Horton) by virtue of a merger with a wholly-owned subsidiary of D.R. Horton. Immediately following the merger, D.R. Horton owned 75% of the Company's outstanding common stock. In connection with the merger, the Company entered into certain agreements with D.R. Horton including a Stockholder’s Agreement, a Master Supply Agreement, and a Shared Services Agreement. D.R. Horton is considered a related party of Forestar under GAAP. At December 31, 2021, D.R. Horton owned approximately 63% of the Company's outstanding common stock. 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. Changes in Presentation and Reclassifications The Company reclassified the change in accrued development costs from the change in accounts payable and other liabilities to the change in accrued development costs in the prior year statement of cash flows to conform to the current year presentation. This reclassification had no net effect on the Company's consolidated operating results, financial position or cash flows. Pending Accounting Standards In March 2020, the Financial Accounting Standards Board (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 such standards to have a material impact on its consolidated financial statements and related disclosures.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment InformationThe Company manages its operations through its real estate segment which is its core business and generates substantially all of its revenues. The real estate segment primarily acquires land and develops infrastructure for single-family residential communities, and its revenues generally come from sales of residential single-family finished lots to local, regional and national homebuilders. The Company has other business activities for which the related assets and operating results are immaterial, and therefore are included within the Company's real estate segment.

Horton at a sales price equal to the carrying value of the land at the time of sale plus additional consideration of 12% to 16% per annum. Each quarter, the Company reviews the performance and outlook for all of its real estate for indicators of potential impairment and performs detailed impairment evaluations and analyses when necessary. As a result of this process, there were no real estate impairment charges recorded for either period presented in the consolidated statements of operations. In the three months ended December 31, 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 $0.6 million and $0.4 million, respectively.

Capitalized Interest [Abstract]
Capitalized Interest [Text Block]	Capitalized Interest The Company capitalizes interest costs to real estate throughout the development period (active real estate). Capitalized interest is charged to cost of sales as the related real estate is sold to the buyer. During periods in which the Company’s active real estate is lower than its debt level, a portion of the interest incurred is reflected as interest expense in the period incurred. In the first three months of fiscal 2022 and fiscal year 2021, the Company’s active real estate exceeded its debt level, and all interest incurred was capitalized to real estate. The following table summarizes the Company’s interest costs incurred, capitalized and expensed in the three months ended December 31, 2021 and 2020. Three Months Ended December 31, 2021 2020 (In millions) Capitalized interest, beginning of period $ 53.7 $ 48.7 Interest incurred 8.2 11.5 Interest charged to cost of sales (9.0) (9.2) Capitalized interest, end of period $ 52.9 $ 51.0

Debt Disclosure [Abstract]
Debt, net	Debt The Company's notes payable at their carrying amounts consist of the following: December 31, September 30, (In millions) Unsecured: Revolving credit facility $ — $ — 3.85% senior notes due 2026 (1) 395.7 395.5 5.0% senior notes due 2028 (1) 296.7 296.5 Other note payable 12.5 12.5 $ 704.9 $ 704.5 ______________ (1) Unamortized debt issuance costs that were deducted from the carrying amounts of the senior notes totaled $7.6 million and $8.0 million at December 31, 2021 and September 30, 2021, respectively. Bank Credit Facility The Company 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 maturity date of the facility is April 16, 2025. 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 calculation based on the book value of the Company's real estate assets and unrestricted cash. Letters of credit issued under the facility reduce the available borrowing capacity. There were no borrowings or repayments under the facility in the three months ended December 31, 2021. At December 31, 2021, there were no borrowings outstanding and $66.3 million of letters of credit issued under the revolving credit facility, resulting in available capacity of $343.7 million. The revolving credit facility includes customary affirmative and negative covenants, events of default and financial covenants. The financial covenants require 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, 2021, the Company was in compliance with all of the covenants, limitations and restrictions of its revolving credit facility. Senior Notes The Company has outstanding senior notes as described below that were issued pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended. The notes represent senior unsecured obligations that rank equally in right of payment to all existing and future senior unsecured indebtedness and may be redeemed prior to maturity, subject to certain limitations and premiums defined in the indenture agreements. The notes are guaranteed by each of the Company's subsidiaries to the extent such subsidiaries guarantee the Company's revolving credit facility. The Company's $400 million principal amount of 3.85% senior notes (the "2026 notes") mature May 15, 2026 with interest payable semi-annually. On or after May 15, 2023, the 2026 notes may be redeemed at 101.925% of their principal amount plus any accrued and unpaid interest. In accordance with the indenture, the redemption price decreases annually thereafter and the 2026 notes can be redeemed at par on or after May 15, 2025 through maturity. The annual effective interest rate of the 2026 notes after giving effect to the amortization of financing costs is 4.1%. The Company's $300 million principal amount of 5.0% senior notes (the "2028 notes") mature March 1, 2028 with interest payable semi-annually. On or after March 1, 2023, the 2028 notes may be redeemed at 102.5% of their principal amount plus any accrued and unpaid interest. In accordance with the indenture, the redemption price decreases annually thereafter and the 2028 notes can be redeemed at par on or after March 1, 2026 through maturity. The annual effective interest rate of the 2028 notes after giving effect to the amortization of financing costs is 5.2%. The indentures governing the senior notes require that, upon the occurrence of both a change of control and a rating decline (each as defined in the respective indenture), the Company offer to purchase the notes at 101% of their principal amount. If the Company or its restricted subsidiaries dispose of assets, under certain circumstances, the Company will be required to either invest the net cash proceeds from such asset sales in its business within a specified period of time, repay certain senior secured debt or debt of its non-guarantor subsidiaries, or make an offer to purchase a principal amount of the notes equal to the excess net cash proceeds at a purchase price of 100% of their principal amount. The indentures contain covenants that, among other things, restrict the ability of the Company and its restricted subsidiaries to pay dividends or distributions, repurchase equity, prepay subordinated debt and make certain investments; incur additional debt or issue mandatorily redeemable equity; incur liens on assets; merge or consolidate with another company or sell or otherwise dispose of all or substantially all of the Company’s assets; enter into transactions with affiliates; and allow to exist certain restrictions on the ability of subsidiaries to pay dividends or make other payments. At December 31, 2021, the Company was in compliance with all of the limitations and restrictions associated with its senior note obligations. Effective April 30, 2020, the Board of Directors authorized the repurchase of up to $30 million of the Company’s debt securities. The authorization has no expiration date. All of the $30 million authorization was remaining at December 31, 2021. Other Note Payable The Company's other note payable of $12.5 million was issued as part of a transaction to acquire real estate for development. The note is non-recourse and is secured by the underlying real estate, accrues interest at 4.0% per annum and matures in October 2023.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax expense for the three months ended December 31, 2021 and 2020 was $13.0 million and $7.1 million, respectively, and the effective tax rate was 24.3% in both periods. The effective tax rate for both periods includes an expense for state income taxes and nondeductible expenses and a benefit related to noncontrolling interests. At December 31, 2021, the Company had deferred tax liabilities, net of deferred tax assets, of $23.0 million. The deferred tax assets were partially offset by a valuation allowance of $1.2 million, resulting in a net deferred tax liability of $24.2 million. At September 30, 2021, deferred tax liabilities, net of deferred tax assets, were $23.2 million. The deferred tax assets were partially offset by a valuation allowance of $1.2 million, resulting in a net deferred tax liability of $24.4 million. The valuation allowance for both periods was recorded because it is more likely than not that a portion of the Company's state deferred tax assets, primarily net operating loss (NOL) carryforwards, will not be realized because the Company is no longer operating in some states or the NOL carryforward periods are too brief to realize the related deferred tax asset. The Company will continue to evaluate both the positive and negative evidence in determining the need for a valuation allowance on its deferred tax assets. Any reversal of the valuation allowance in future periods will impact the effective tax rate.

At December 31, 2021, $748.2 million remained available for issuance under the shelf registration statement, of which $298.2 million was reserved for sales under the at-the-market equity offering program.

Restricted stock unit awards may be based on performance (performance-based) or on service over a requisite time period (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 voting rights until vested. There were no new grants of time-based RSUs in the three months ended December 31, 2021. Total stock-based compensation expense related to the Company's restricted stock units for the three months ended December 31, 2021 and 2020 was $0.4 million and $0.3 million, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contractual Obligations and Off-Balance Sheet Arrangements In support of the Company's residential lot development business, it issues letters of credit under the revolving credit facility and has a surety bond program that provides financial assurance to beneficiaries related to the execution and performance of certain development obligations. At December 31, 2021, the Company had outstanding letters of credit of $66.3 million under the revolving credit facility and surety bonds of $528.2 million issued by third parties to secure performance under various contracts. The Company expects that its performance obligations secured by these letters of credit and bonds will generally be completed in the ordinary course of business and in accordance with the applicable contractual terms. When the Company completes its performance obligations, the related letters of credit and bonds are generally released shortly thereafter, leaving the Company with no continuing obligations. The Company has no material third-party guarantees. Litigation The Company is involved in various legal proceedings that arise from time to time in the ordinary course of business and believes that adequate reserves have been established for any probable losses. The Company does not believe that the outcome of any of these proceedings will have a significant adverse effect on its financial position, long-term results of operations or cash flows. It is possible, however, that charges related to these matters could be significant to the Company's results or cash flows in any one accounting period.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants. In arriving at a fair value measurement, the Company uses a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable. The three levels of inputs used to establish fair value are the following: • Level 1 — Quoted prices in active markets for identical assets or liabilities; • Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company elected not to use the fair value option for cash and cash equivalents and debt. 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, 2021 and September 30, 2021. Fair Value at December 31, 2021 Carrying Value Level 1 Level 2 Level 3 Total (in millions) Cash and cash equivalents (a) $ 162.5 $ 162.5 $ — $ — $ 162.5 Debt (b) (c) 704.9 — 709.9 12.5 722.4 Fair Value at September 30, 2021 Carrying Value Level 1 Level 2 Level 3 Total (in millions) Cash and cash equivalents (a) $ 153.6 $ 153.6 $ — $ — $ 153.6 Debt (b) (c) 704.5 — 711.2 12.5 723.7 _____________________ (a) The fair values of cash and cash equivalents approximate their carrying values due to their short-term nature and are classified as Level 1 within the fair value hierarchy. (b) At December 31, 2021 and September 30, 2021, debt primarily consisted of the Company's senior notes. The fair value of the senior notes is determined based on quoted market prices, which is classified as Level 2 within the fair value hierarchy. (c) The fair value of the Company's other note payable approximates its carrying value due to its short-term nature and is classified as Level 3 within the fair value hierarchy. Non-financial assets measured at fair value on a non-recurring basis primarily include real estate assets which the company reviews for indicators of potential impairment and performs impairment evaluations when necessary.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited, consolidated financial statements include the accounts of Forestar Group Inc. (Forestar) and all of its 100% owned, majority-owned and controlled subsidiaries, which are collectively referred to as the Company unless the context otherwise requires. The Company accounts for its investment in other entities in which it has significant influence over operations and financial policies using the equity method. All intercompany accounts, transactions and balances have been eliminated in consolidation. Noncontrolling interests in consolidated pass-through entities are recognized before income taxes. The transactions included in net income in the consolidated statements of operations are the same as those that would be presented in comprehensive income. Thus, the Company's net income equates to comprehensive income. 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, 2021, 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, 2021. In October 2017, Forestar became a majority-owned subsidiary of D.R. Horton, Inc. (D.R. Horton) by virtue of a merger with a wholly-owned subsidiary of D.R. Horton. Immediately following the merger, D.R. Horton owned 75% of the Company's outstanding common stock. In connection with the merger, the Company entered into certain agreements with D.R. Horton including a Stockholder’s Agreement, a Master Supply Agreement, and a Shared Services Agreement. D.R. Horton is considered a related party of Forestar under GAAP. At December 31, 2021, D.R. Horton owned approximately 63% of the Company's outstanding common stock.
Use of Estimates, Policy [Policy Text Block]	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.
Reclassification, Comparability Adjustment	Changes in Presentation and Reclassifications The Company reclassified the change in accrued development costs from the change in accounts payable and other liabilities to the change in accrued development costs in the prior year statement of cash flows to conform to the current year presentation. This reclassification had no net effect on the Company's consolidated operating results, financial position or cash flows.
New Accounting Pronouncements, Policy [Policy Text Block]	Pending Accounting Standards In March 2020, the Financial Accounting Standards Board (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 such standards to have a material impact on its consolidated financial statements and related disclosures.
