| Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of Long-Lived Assets In accordance with ASC 360, our property and equipment and right-of-use assets related to operating leases are reviewed for possible impairment if there are indicators that their carrying amounts are not recoverable. The carrying amount of a long-lived asset is considered not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss shall be measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value. | | |
| Deposit Contracts, Policy [Policy Text Block] | Earnest Money Deposits In the ordinary course of business, the Company enters into land and lot option contracts in order to procure land for the construction of homes in the future. Pursuant to these option contracts, the Company generally provides a deposit to the seller as consideration for the right to purchase land at different times in the future, usually at predetermined prices. Such contracts enable the Company to defer acquiring portions of properties owned by third parties or unconsolidated entities until the Company has determined whether and when to exercise its option, which reduces the Company’s financial risk associated with long-term land holdings. Option deposits and pre-acquisition costs (such as environmental testing, surveys, engineering, and entitlement costs) are capitalized if the costs are directly identifiable with the land under option and acquisition of the property is probable. Such costs are reflected in earnest money deposits and are reclassified to inventory upon taking title to the land. The Company writes off deposits and pre-acquisition costs if it becomes probable that the Company will not proceed with the project or recover the capitalized costs. Such decisions take into consideration changes in local market conditions, the timing of required land takedowns, the availability and best use of necessary incremental capital, and other factors. | | |

| Significant Accounting Policies | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) as set forth in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) and applicable regulations of the Securities and Exchange Commission (“SEC”). Principles of Consolidation The accompanying consolidated financial statements include the accounts of Green Brick Partners, Inc., its controlled subsidiaries, and variable interest entities in which Green Brick Partners, Inc. or one of its controlled subsidiaries is deemed to be the primary beneficiary (together, the “Company”, “we”, or “Green Brick”). The Company evaluated its wholly-owned subsidiaries and controlled builder under ASC 810, Consolidation (“ASC 810”) and concluded that its controlled builder is a variable interest entity (“VIE”). The Company owns a 50% equity interest and a 51% voting interest in its controlled builder. In addition, the Company appoints two of the three board managers of its controlled builder and is able to exercise control over its operations. The Company accounts for its controlled builder under the variable interest model and is the primary beneficiary of its controlled builder in accordance with ASC 810. All intercompany balances and transactions have been eliminated in consolidation. The Company uses the equity method of accounting for its investments in unconsolidated entities over which it exercises significant influence but does not have a controlling interest. Under the equity method, the Company’s share of the unconsolidated entities’ earnings or losses is included in the consolidated statements of income. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management of the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes, including the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation with no impact to net income in any period. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. The cash balances of the Company are held with multiple financial institutions. At times, cash balances at certain banks and financial institutions may exceed insurable amounts. The Company believes it mitigates this risk by monitoring the financial stability of institutions holding material cash balances. The Company has not experienced any losses in such accounts and believes that the risk of loss is minimal. Restricted Cash Restricted cash primarily relates to cash held in escrow for sales of developed lots to third parties and customer deposits from homebuyers. Receivables Receivables consist of amounts collectible from manufacturing rebates earned by our homebuilders during the normal course of business, amounts collectible from third-party escrow agents related to closings on land, lots and homes, amounts collectible related to mechanic’s lien contracts, and income tax receivables. As of December 31, 2021 and 2020, all amounts are considered fully collectible and no allowance for doubtful accounts is recorded. Any allowance for doubtful accounts is estimated based on our historical losses, the existing economic conditions, and the financial stability of our customers. Receivables are written off in the period that they are deemed uncollectible. Inventory and Cost of Revenues Inventory consists of undeveloped land, raw land scheduled for development, land in the process of development, land held for sale, developed lots, homes completed and under construction, and model homes. Inventory is valued at cost unless the carrying value is determined to be not recoverable in which case the affected inventory is written down to fair value. Cost includes any related pre-acquisition costs that are directly identifiable with a specific property so long as those pre-acquisition costs are anticipated to be recoverable at the sale of the property. Residential lots held for sale and lots held for development include the initial cost of acquiring the land as well as certain costs capitalized related to developing the land into individual residential lots including direct overhead, interest and real estate taxes. Land development and other project costs, including direct overhead, interest and property taxes incurred during development and home construction, are capitalized. Land development and other common costs that benefit an entire community are allocated to individual lots or homes based on relative sales value. The costs of completed lots are transferred to work in process when home construction begins. Home construction costs and related carrying charges (principally interest and real estate taxes) are allocated to the cost of individual homes. Inventory costs for completed homes are expensed upon closing and delivery of the homes. Changes to estimated total land development costs subsequent to initial home closings in a community are generally allocated to the unclosed homes and lots in the community on a pro-rata basis. The life cycle of a community generally ranges from 24 to 72 months, commencing with the acquisition of land, continuing through the land development phase, construction, and concluding with the sale and delivery of homes. We recognize costs as incurred on our mechanic’s lien contracts. Impairment of Inventory In accordance with ASC 360, Property, Plant, and Equipment (“ASC 360”), we evaluate our inventory for indicators of impairment by individual community and development during each reporting period. For our builder operations segments, during each reporting period, community gross margins on closed homes, average margins of homes within backlog, and community outlook factors are reviewed by management. In the event that this review suggests higher potential for losses at a specific community, the Company monitors such communities by adding them to its “watchlist” communities, and, when an impairment indicator is present, further analysis is performed. For our land development segment, we perform a quarterly review for indicators of impairment for each project which involves comparing anticipated lot sale revenues to projected costs (i.e. lot gross margins). For lots designated for our builders, we review land for indicators of impairment on a consolidated level, looking at overall projected home gross margins. In determining the allocation of costs to a particular land parcel, we rely on project budgets which are based on a variety of assumptions, including assumptions about development schedules and future costs to be incurred. It is common that actual results differ from budgeted amounts for various reasons, including delays, changes in costs that have not been committed, unforeseen issues encountered during project development that fall outside the scope of existing contracts, or items that ultimately cost more or less than the budgeted amount. We apply procedures to maintain best estimates in our budgets, including assessing and revising project budgets on a periodic basis, obtaining commitments from subcontractors and vendors for future costs to be incurred and utilizing the most recent information available to estimate costs. Each reporting period, management reviews each real estate asset which has an indicator of impairment in order to determine whether the estimated remaining undiscounted future cash flows are more or less than the asset’s carrying value. The estimated cash flows are determined by projecting the remaining revenue from closings based on the contractual lot takedowns remaining or historical and projected home sales or delivery absorptions for homebuilding operations and then comparing such projections to the remaining projected expenditures for development or home construction. Remaining projected expenditures are based on the most current pricing/bids received from subcontractors for current phases or homes under development. For future phases of land development, management uses its judgment to project potential cost increases. In determining the estimated cash flows for land held for sale, management considers recent comparisons to market comparable transactions, bona fide letters of intent from outside parties, executed sales contracts, broker quotes, and similar information. When projecting revenue, management does not assume improvement in market conditions. If the estimated undiscounted cash flows are more than the asset’s carrying value, no impairment adjustment is required. However, if the estimated undiscounted cash flows are less than the asset’s carrying value, the asset is deemed impaired and will be written down to fair value less associated costs to sell. These impairment evaluations require us to make estimates and assumptions regarding future conditions, including the timing and amounts of development costs and sales prices of real estate assets, to determine if expected future cash flows will be sufficient to recover the asset’s carrying value. Fair value is determined based on estimated future cash flows discounted for inherent risks associated with real estate assets. These discounted cash flows are impacted by expected risk based on estimated land development activities, construction and delivery timelines, market risk of price erosion, uncertainty of development or construction cost increases, and other risks specific to the asset or market conditions where the asset is located when the assessment is made. These factors are specific to each community and may vary among communities. When estimating cash flows of a community, management makes various assumptions, including: (i) expected sales prices and sales incentives to be offered, including the number of homes available, pricing and incentives being offered by us or other builders, and future sales price adjustments based on market and economic trends; (ii) expected sales pace and cancellation rates based on local housing market conditions, competition and historical trends; (iii) costs expended to date and expected to be incurred including, but not limited to, land and land development costs, home construction costs, interest costs, indirect construction and overhead costs, and selling and marketing costs; (iv) alternative product offerings that may be offered that could have an impact on sales pace, sales price and/or building costs; and (v) alternative uses for the property. Many assumptions are interdependent and a change in one may require a corresponding change to other assumptions. For example, increasing or decreasing sales absorption rates has a direct impact on the estimated per unit sales price of a home, the level of time-sensitive costs (such as indirect construction, overhead and carrying costs), and selling and marketing costs (such as model home maintenance costs and advertising costs). Due to uncertainties in the estimation process, the volatility in demand for new housing and the long life cycle of many communities, actual results could differ significantly from such estimates. Capitalization of Interest The Company capitalizes interest costs incurred to inventory during development and other qualifying activities. Interest capitalized as cost of inventory is charged to cost of revenues as related homes, land and lots are closed. Interest incurred on undeveloped land is directly expensed and included in interest expense in our consolidated statements of income. Investments in Unconsolidated Entities In accordance with ASC 323, Investments - Equity Method and Joint Ventures (“ASC 323”) , the Company uses the equity method of accounting for its investments in unconsolidated entities over which it exercises significant influence but does not have a controlling interest. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for the Company ’ s share of equity in the unconsolidated entity’s earnings or losses . The Company evaluates the carrying amount of the investments in unconsolidated entities for impairment in accordance with ASC 323. If the Company determines that a loss in the value of the investment is other than temporary, the Company writes down the investment to its estimated fair value. Any such losses are recorded to e quity in income of unconsolidated entities in the Company ’ s consolidated statements of income. Due to uncertainties in the estimation process and the volatility in demand for new housing, actual results could differ significantly from such estimates. The Company has made an election to classify distributions received from unconsolidated entities using the nature of the distribution approach. Distributions received are classified as cash inflows from operating activities based on the nature of the activities of the investee that generated the distribution. Variable Interest Entities The Company accounts for variable interest entities (“VIEs”) in accordance with ASC 810. In accordance with ASC 810, an entity is a VIE when: (a) the equity investment at risk in the entity is not sufficient to permit the entity to finance its activities without additional subordinated financial support provided by other parties, including the equity holders; (b) the entity’s equity holders as a group either (i) lack the direct or indirect ability to make decisions about the entity, (ii) are not obligated to absorb expected losses of the entity or (iii) do not have the right to receive expected residual returns of the entity; or (c) the entity’s equity holders have voting rights that are not proportionate to their economic interests, and the activities of the entity involve or are conducted on behalf of the equity holder with disproportionately few voting rights. If an entity is deemed to be a VIE pursuant to ASC 810, the enterprise that has both (i) the power to direct the activities of the VIE that most significantly impacts the entity’s economic performance and (ii) the obligation to absorb the expected losses of the entity or right to receive benefits from the entity that could be potentially significant to the VIE is considered the primary beneficiary and must consolidate the VIE. In accordance with ASC 810, the Company performs ongoing reassessments of whether it is the primary beneficiary of a VIE. The financial statements of the VIEs for which the Company is considered to be the primary beneficiary, if any, are consolidated in the Company’s consolidated financial statements. The noncontrolling interests attributable to other beneficiaries of the VIEs are included as noncontrolling interests in the Company’s consolidated financial statements. Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of the assets using the straight-line method. The estimated useful lives of assets range from 1 to 15 years. Repairs and maintenance are expensed as incurred. Impairment of Long-Lived Assets In accordance with ASC 360, our property and equipment and right-of-use assets related to operating leases are reviewed for possible impairment if there are indicators that their carrying amounts are not recoverable. The carrying amount of a long-lived asset is considered not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss shall be measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value. Earnest Money Deposits In the ordinary course of business, the Company enters into land and lot option contracts in order to procure land for the construction of homes in the future. Pursuant to these option contracts, the Company generally provides a deposit to the seller as consideration for the right to purchase land at different times in the future, usually at predetermined prices. Such contracts enable the Company to defer acquiring portions of properties owned by third parties or unconsolidated entities until the Company has determined whether and when to exercise its option, which reduces the Company’s financial risk associated with long-term land holdings. Option deposits and pre-acquisition costs (such as environmental testing, surveys, engineering, and entitlement costs) are capitalized if the costs are directly identifiable with the land under option and acquisition of the property is probable. Such costs are reflected in earnest money deposits and are reclassified to inventory upon taking title to the land. The Company writes off deposits and pre-acquisition costs if it becomes probable that the Company will not proceed with the project or recover the capitalized costs. Such decisions take into consideration changes in local market conditions, the timing of required land takedowns, the availability and best use of necessary incremental capital, and other factors. Under ASC 810, a non-refundable deposit paid to an entity is deemed to be a variable interest that will absorb some or all of the entity’s expected losses if they occur and, as such, the Company’s land and lot option contracts are considered variable interests. The Company’s option contract deposits along with any related pre-acquisition costs represent the Company’s maximum exposure to the land seller if the Company elects not to purchase the optioned property. Therefore, whenever the Company enters into an option or purchase contract with an entity and makes a non-refundable deposit, a VIE assessment is performed. However, the Company generally has little control or power to direct the activities that most significantly impact the VIE’s economic performance due to the Company’s lack of an equity interest in them. Additionally, creditors of the VIE typically have no material recourse against the Company, and the Company does not provide financial or other support to these VIEs other than as stipulated in the option contracts. In accordance with ASC 810, the Company performs ongoing reassessments of whether the Company is the primary beneficiary of a VIE. Intangible Assets Intangible assets, net consists of the estimated fair value of the acquired trade name, net of amortization. The trade name has a definite life and is amortized over ten years. Intangible assets are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized if the carrying amount of the asset exceeds the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. The impairment loss recorded would be the excess of the asset’s carrying value over its fair value. Fair value would be determined using a discounted cash flow analysis or other valuation technique. Goodwill The excess of the purchase price of a business acquisition over the net fair value of assets acquired and liabilities assumed is capitalized as goodwill in accordance with ASC 805, Business Combinations (“ASC 805”). The allocation to goodwill represents the excess of the purchase price, including contingent consideration, over the estimated fair value of assets acquired and liabilities assumed. Goodwill results primarily from operational synergies expected from the business combination. Goodwill is assessed for impairment at least annually in the fourth quarter, or more frequently if certain impairment indicators are present. A goodwill impairment loss is recognized for the amount by which the carrying amount of the reporting unit, including goodwill, exceeds its fair value. The Company reviews goodwill at the reporting unit level for impairment. The Company first performs a qualitative assessment to determine whether it is more likely than not that fair value of the reporting level is less than its carrying amount. Qualitative factors include adverse macroeconomic conditions, industry and market conditions, overall financial performance, reporting unit specific events and entity specific events. If, after completing a qualitative assessment, the Company concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the Company must perform a quantitative test to evaluate goodwill for impairment. For the quantitative impairment test, the Company calculates the fair value of the reporting unit and compares that amount to the reporting unit’s carrying value. The fair value of the reporting unit is determined by using generally accepted valuation techniques, including discounted cash flow models and market multiple analysis. The Company’s valuation methodology for assessing impairment would require management to make judgments and assumptions based on historical experience and projections of future operating performance. The Company recognizes goodwill impairment, if any, as the excess of the reporting unit’s carrying value over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. Warranties The Company accrues an estimate of its exposure to warranty claims based on both current and historical home closings data and warranty costs incurred. The Company offers homeowners a comprehensive third-party warranty on each home. Homes are generally covered by a ten-year warranty for qualified and defined structural defects, one year for defects and products used, and two years for electrical, plumbing, heating, ventilation, and air conditioning parts and labor. Warranty accruals are included within accrued expenses on the consolidated balance sheets. Any legal costs associated with loss contingencies related to warranties are expensed as incurred. Debt Issuance Costs Debt issuance costs represent costs incurred related to the senior unsecured notes and revolving secured and unsecured credit facilities, including amendments thereto, and reduce the carrying amount of debt on the consolidated balance sheets. These costs are subject to capitalization to inventory over the term of the related debt facility using the straight-line method, which approximates the effective interest rate method for our senior unsecured notes and notes payable. Business Combinations Acquisitions are accounted for in accordance with ASC 805. Following the determination that control of a business and its inputs, processes and outputs were obtained in exchange for consideration, all material assets and liabilities of the business, including contingent consideration, are measured and recognized at fair value as of the date of the acquisition to reflect the purchase price. Depending on the fair value of net assets acquired, the purchase price allocation may or may not result in goodwill. Contingent consideration is subsequently remeasured to fair value at each reporting date until the contingency is resolved, with any change in fair value recognized in the consolidated statements of income. Redeemable Noncontrolling Interest in Equity of Consolidated Subsidiary Redeemable noncontrolling interest in equity of consolidated subsidiary represents equity related to a put option held by a minority shareholder of a subsidiary. Based on the put option structure, the minority shareholder’s interest in the controlled subsidiary is classified as a redeemable noncontrolling interest on the consolidated balance sheets. The accretion of the redeemable noncontrolling interest to its estimated redemption value is recorded in additional paid-in capital on the consolidated balance sheets if the estimated redemption value, net of accretion, is greater than the current value of the noncontrolling interest capital account. Revenue Recognition Contracts with Customers The Company derives revenues from two primary sources: the closing and delivery of homes through our builder operations segments and the closing of lots and land sold to third parties through our land development segment. All of our revenue is from contracts with customers. Contract Liabilities The Company requires homebuyers to submit a deposit for home purchases and requires third-party buyers to submit a deposit in connection with land sale or lot option contracts. The non-refundable deposits serve as an incentive for performance under homebuilding and land sale or development contracts. Cash received as customer deposits, if held in escrow, is reflected as restricted cash and as customer and builder deposits on the consolidated balance sheets. Performance Obligations The Company’s contracts with homebuyers contain a single performance obligation. The performance obligation is satisfied when homes are completed and control is transferred to the buyer which occurs when legal title has been transferred to the buyer. The Company does not have any variable consideration associated with home sales transactions. Revenue from mechanic’s lien contracts in which the Company serves as the general contractor for custom homes where the customer, and not the Company, owns the underlying land and improvements is recognized based on the input method, where progress toward completion is measured by relating the actual cost of work performed to date to the estimated total cost of the respective contracts. Lot option contracts contain multiple performance obligations. The performance obligations are satisfied as lots are closed and legal title has been transferred to the builder. For lot option contracts, individual performance obligations are accounted for separately. The transaction price is allocated to the separate performance obligations on a relative stand-alone selling price basis. Certain lot option contracts require escalations in lot price over the option period. Any escalator is not collectible until the lot closing occurs. While we recognize lot escalators as variable consideration within the transaction price, we do not recognize escalator revenue until a builder closes on a lot subject to an escalator as the escalator relates to general inflation and holding costs. Occasionally, the Company sells developed and undeveloped land parcels. If the land parcel is developed prior to the sale of the land, the revenue is recognized at closing since we deliver a single performance obligation in the form of a developed parcel. We also recognize revenue at closing on undeveloped land parcel sales as there are no other obligations beyond delivering the undeveloped land. Homebuyers are not obligated to pay for a home until the closing and delivery of the home. The selling price of a home is based on the contract price adjusted for any change orders, which are considered modifications of the contract price. Homebuilders are not obligated to pay for developed lots prior to control of the lots and any associated improvements being transferred to them. The term of our lot option contracts is generally based upon the number of lots being purchased and an agreed upon lot takedown schedule, which can be in excess of one year. Lots cannot be taken down until development is substantially complete. There is no significant financing component related to our third-party lot sales. The Company does not sell warranties outside of the customary workmanship warranties provided on homes or developed lots at the time of sale. The warranties offered to homebuyers are short term, with the exception of ten-year warranties on structural concerns for homes. As these are assurance-type warranties, there is no separate performance obligation related to warranties provided to homebuyers or homebuilders. Significant Judgments and Estimates There are no significant judgments involved in the recognition of residential units revenue. The performance obligation of delivering a completed home is satisfied upon the sale closing when title transfers to the buyer. There are no significant judgments involved in the recognition of land and lots revenue. The performance obligation of delivering land and lots is satisfied upon the closing of the sale when title transfers to the buyer. Contract Costs The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company pays sales commissions to employees and/or outside realtors related to individual home sales which are expensed as incurred at the time of closing. Commissions on the sale of land parcels are also expensed as incurred upon closing. Sales commissions on the sale of homes are included in the selling, general, and administrative expenses in the consolidated statements of income. The Company also pays builder incentives to employees which are based on the time it takes to build individual homes, as well as quality inspection completion and customer satisfaction. The builder incentives do not represent incremental costs that would require capitalization as we would incur these costs whether or not we sold the home. As such, we recognize builder incentives as expense at the time they are incurred and paid. Advertising costs, sales salaries and certain costs associated with model homes, such as signage, do not qualify for capitalization under ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers , as they are not incremental costs of obtaining a contract. As such, we expense these costs to selling, general and administrative expense as incurred. Costs incurred related to model home furnishings and sales office construction are capitalized and included in property and equipment, net on the consolidated balance sheets. Selling, General and Administrative Expense Selling, general and administrative expense represents salaries, benefits, share-based compensation, property taxes on finished homes, sales commissions, depreciation, amortization, advertising and marketing, rent, and other administrative items, and is recorded in the period incurred. Advertising Expense The Company expenses advertising costs as incurred. Advertising costs are included in selling, general and administrative expense in the consolidated statements of income. Advertising expense for the years ended December 31, 2021, 2020 and 2019 totaled $1.3 million, $2.2 million and $2.1 million, respectively. Interest Expense Interest expense consists primarily of interest costs incurred on our debt that are not capitalized, and amortization of debt issuance costs. We capitalize interest costs incurred to inventory during development and other qualifying activities. Debt issuance costs are capitalized to inventory over the term of the underlying debt using the straight-line method, which approximates the effective interest rate method for our senior unsecured notes and notes payable, in accordance with our interest capitalization policy. All interest costs were capitalized during the years ended December 31, 2021, 2020 and 2019. Net Income Attributable to Green Brick Partners, Inc. per Common Share Basic earnings per common share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during each period, adjusted for non-vested shares of restricted stock awards during each period. Net income allocated to common shareholders is net income adjusted for preferred stock dividends including dividends declared and cumulative dividends related to the current dividend period that have not been declared as of period end. Diluted earnings per share is calculated using the treasury stock method and includes the effect of all dilutive securities, including stock options and restricted stock awards. The Company’s restricted stock awards have the right to receive forfeitable dividends on an equal basis with common stock and therefore are not considered participating securities that must be included in the calculation of net income per common share using the two-class method. Cost Recognition Lot acquisition, materials, direct costs, interest and indirect costs related to the acquisition, development, and construction of lots and homes are capitalized. Direct and indirect costs of developing residential lots are allocated evenly to all appl | | |

| Goodwill and Intangible Assets, Policy [Policy Text Block] | Intangible Assets Intangible assets, net consists of the estimated fair value of the acquired trade name, net of amortization. The trade name has a definite life and is amortized over ten years. Intangible assets are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized if the carrying amount of the asset exceeds the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. The impairment loss recorded would be the excess of the asset’s carrying value over its fair value. Fair value would be determined using a discounted cash flow analysis or other valuation technique. Goodwill The excess of the purchase price of a business acquisition over the net fair value of assets acquired and liabilities assumed is capitalized as goodwill in accordance with ASC 805, Business Combinations (“ASC 805”). The allocation to goodwill represents the excess of the purchase price, including contingent consideration, over the estimated fair value of assets acquired and liabilities assumed. Goodwill results primarily from operational synergies expected from the business combination. Goodwill is assessed for impairment at least annually in the fourth quarter, or more frequently if certain impairment indicators are present.

| Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include the accounts of Green Brick Partners, Inc., its controlled subsidiaries, and variable interest entities in which Green Brick Partners, Inc. or one of its controlled subsidiaries is deemed to be the primary beneficiary (together, the “Company”, “we”, or “Green Brick”). The Company evaluated its wholly-owned subsidiaries and controlled builder under ASC 810, Consolidation (“ASC 810”) and concluded that its controlled builder is a variable interest entity (“VIE”). The Company owns a 50% equity interest and a 51% voting interest in its controlled builder. In addition, the Company appoints two of the three board managers of its controlled builder and is able to exercise control over its operations. The Company accounts for its controlled builder under the variable interest model and is the primary beneficiary of its controlled builder in accordance with ASC 810. All intercompany balances and transactions have been eliminated in consolidation. The Company uses the equity method of accounting for its investments in unconsolidated entities over which it exercises significant influence but does not have a controlling interest. Under the equity method, the Company’s share of the unconsolidated entities’ earnings or losses is included in the consolidated statements of income. | | |
| Use of Estimates | Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management of the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes, including the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. | | |

| Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. The cash balances of the Company are held with multiple financial institutions. At times, cash balances at certain banks and financial institutions may exceed insurable amounts. The Company believes it mitigates this risk by monitoring the financial stability of institutions holding material cash balances. The Company has not experienced any losses in such accounts and believes that the risk of loss is minimal. | | |
| Restricted Cash | Restricted CashRestricted cash primarily relates to cash held in escrow for sales of developed lots to third parties and customer deposits from homebuyers. | | |
| Accounts Receivable and Allowance for Doubtful Accounts | Receivables Receivables consist of amounts collectible from manufacturing rebates earned by our homebuilders during the normal course of business, amounts collectible from third-party escrow agents related to closings on land, lots and homes, amounts collectible related to mechanic’s lien contracts, and income tax receivables. As of December 31, 2021 and 2020, all amounts are considered fully collectible and no allowance for doubtful accounts is recorded. Any allowance for doubtful accounts is estimated based on our historical losses, the existing economic conditions, and the financial stability of our customers. Receivables are written off in the period that they are deemed uncollectible. | | |
| Inventory and Impairment of Real Estate Inventory | Inventory and Cost of Revenues Inventory consists of undeveloped land, raw land scheduled for development, land in the process of development, land held for sale, developed lots, homes completed and under construction, and model homes. Inventory is valued at cost unless the carrying value is determined to be not recoverable in which case the affected inventory is written down to fair value. Cost includes any related pre-acquisition costs that are directly identifiable with a specific property so long as those pre-acquisition costs are anticipated to be recoverable at the sale of the property. Residential lots held for sale and lots held for development include the initial cost of acquiring the land as well as certain costs capitalized related to developing the land into individual residential lots including direct overhead, interest and real estate taxes. Land development and other project costs, including direct overhead, interest and property taxes incurred during development and home construction, are capitalized. Land development and other common costs that benefit an entire community are allocated to individual lots or homes based on relative sales value. The costs of completed lots are transferred to work in process when home construction begins. Home construction costs and related carrying charges (principally interest and real estate taxes) are allocated to the cost of individual homes. Inventory costs for completed homes are expensed upon closing and delivery of the homes. Changes to estimated total land development costs subsequent to initial home closings in a community are generally allocated to the unclosed homes and lots in the community on a pro-rata basis. The life cycle of a community generally ranges from 24 to 72 months, commencing with the acquisition of land, continuing through the land development phase, construction, and concluding with the sale and delivery of homes. We recognize costs as incurred on our mechanic’s lien contracts. Impairment of Inventory In accordance with ASC 360, Property, Plant, and Equipment (“ASC 360”), we evaluate our inventory for indicators of impairment by individual community and development during each reporting period. For our builder operations segments, during each reporting period, community gross margins on closed homes, average margins of homes within backlog, and community outlook factors are reviewed by management. In the event that this review suggests higher potential for losses at a specific community, the Company monitors such communities by adding them to its “watchlist” communities, and, when an impairment indicator is present, further analysis is performed. For our land development segment, we perform a quarterly review for indicators of impairment for each project which involves comparing anticipated lot sale revenues to projected costs (i.e. lot gross margins). For lots designated for our builders, we review land for indicators of impairment on a consolidated level, looking at overall projected home gross margins. In determining the allocation of costs to a particular land parcel, we rely on project budgets which are based on a variety of assumptions, including assumptions about development schedules and future costs to be incurred. It is common that actual results differ from budgeted amounts for various reasons, including delays, changes in costs that have not been committed, unforeseen issues encountered during project development that fall outside the scope of existing contracts, or items that ultimately cost more or less than the budgeted amount. We apply procedures to maintain best estimates in our budgets, including assessing and revising project budgets on a periodic basis, obtaining commitments from subcontractors and vendors for future costs to be incurred and utilizing the most recent information available to estimate costs. Each reporting period, management reviews each real estate asset which has an indicator of impairment in order to determine whether the estimated remaining undiscounted future cash flows are more or less than the asset’s carrying value. The estimated cash flows are determined by projecting the remaining revenue from closings based on the contractual lot takedowns remaining or historical and projected home sales or delivery absorptions for homebuilding operations and then comparing such projections to the remaining projected expenditures for development or home construction. Remaining projected expenditures are based on the most current pricing/bids received from subcontractors for current phases or homes under development. For future phases of land development, management uses its judgment to project potential cost increases. In determining the estimated cash flows for land held for sale, management considers recent comparisons to market comparable transactions, bona fide letters of intent from outside parties, executed sales contracts, broker quotes, and similar information. When projecting revenue, management does not assume improvement in market conditions. If the estimated undiscounted cash flows are more than the asset’s carrying value, no impairment adjustment is required. However, if the estimated undiscounted cash flows are less than the asset’s carrying value, the asset is deemed impaired and will be written down to fair value less associated costs to sell. These impairment evaluations require us to make estimates and assumptions regarding future conditions, including the timing and amounts of development costs and sales prices of real estate assets, to determine if expected future cash flows will be sufficient to recover the asset’s carrying value. Fair value is determined based on estimated future cash flows discounted for inherent risks associated with real estate assets. These discounted cash flows are impacted by expected risk based on estimated land development activities, construction and delivery timelines, market risk of price erosion, uncertainty of development or construction cost increases, and other risks specific to the asset or market conditions where the asset is located when the assessment is made. These factors are specific to each community and may vary among communities. When estimating cash flows of a community, management makes various assumptions, including: (i) expected sales prices and sales incentives to be offered, including the number of homes available, pricing and incentives being offered by us or other builders, and future sales price adjustments based on market and economic trends; (ii) expected sales pace and cancellation rates based on local housing market conditions, competition and historical trends; (iii) costs expended to date and expected to be incurred including, but not limited to, land and land development costs, home construction costs, interest costs, indirect construction and overhead costs, and selling and marketing costs; (iv) alternative product offerings that may be offered that could have an impact on sales pace, sales price and/or building costs; and (v) alternative uses for the property. Many assumptions are interdependent and a change in one may require a corresponding change to other assumptions. For example, increasing or decreasing sales absorption rates has a direct impact on the estimated per unit sales price of a home, the level of time-sensitive costs (such as indirect construction, overhead and carrying costs), and selling and marketing costs (such as model home maintenance costs and advertising costs). Due to uncertainties in the estimation process, the volatility in demand for new housing and the long life cycle of many communities, actual results could differ significantly from such estimates. | | |
| Equity Method Investments | Investments in Unconsolidated Entities In accordance with ASC 323, Investments - Equity Method and Joint Ventures (“ASC 323”) , the Company uses the equity method of accounting for its investments in unconsolidated entities over which it exercises significant influence but does not have a controlling interest. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for the Company ’ s share of equity in the unconsolidated entity’s earnings or losses . The Company evaluates the carrying amount of the investments in unconsolidated entities for impairment in accordance with ASC 323. If the Company determines that a loss in the value of the investment is other than temporary, the Company writes down the investment to its estimated fair value. Any such losses are recorded to e quity in income of unconsolidated entities in the Company ’ s consolidated statements of income. Due to uncertainties in the estimation process and the volatility in demand for new housing, actual results could differ significantly from such estimates. The Company has made an election to classify distributions received from unconsolidated entities using the nature of the distribution approach. Distributions received are classified as cash inflows from operating activities based on the nature of the activities of the investee that generated the distribution. | | |
| Capitalization of Interest | Capitalization of Interest The Company capitalizes interest costs incurred to inventory during development and other qualifying activities. Interest capitalized as cost of inventory is charged to cost of revenues as related homes, land and lots are closed. Interest incurred on undeveloped land is directly expensed and included in interest expense in our consolidated statements of income. | | |
| Earnest Money Deposits | Variable Interest EntitiesThe Company accounts for variable interest entities (“VIEs”) in accordance with ASC 810. In accordance with ASC 810, an entity is a VIE when: (a) the equity investment at risk in the entity is not sufficient to permit the entity to finance its activities without additional subordinated financial support provided by other parties, including the equity holders; (b) the entity’s equity holders as a group either (i) lack the direct or indirect ability to make decisions about the entity, (ii) are not obligated to absorb expected losses of the entity or (iii) do not have the right to receive expected residual returns of the entity; or (c) the entity’s equity holders have voting rights that are not proportionate to their economic interests, and the activities of the entity involve or are conducted on behalf of the equity holder with disproportionately few voting rights. If an entity is deemed to be a VIE pursuant to ASC 810, the enterprise that has both (i) the power to direct the activities of the VIE that most significantly impacts the entity’s economic performance and (ii) the obligation to absorb the expected losses of the entity or right to receive benefits from the entity that could be potentially significant to the VIE is considered the primary beneficiary and must consolidate the VIE. In accordance with ASC 810, the Company performs ongoing reassessments of whether it is the primary beneficiary of a VIE. The financial statements of the VIEs for which the Company is considered to be the primary beneficiary, if any, are consolidated in the Company’s consolidated financial statements. The noncontrolling interests attributable to other beneficiaries of the VIEs are included as noncontrolling interests in the Company’s consolidated financial statements. | | |
| Property and Equipment, Net | Property and Equipment, NetProperty and equipment are stated at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of the assets using the straight-line method. The estimated useful lives of assets range from 1 to 15 years. Repairs and maintenance are expensed as incurred. | | |
| Warranties | Warranties The Company accrues an estimate of its exposure to warranty claims based on both current and historical home closings data and warranty costs incurred. The Company offers homeowners a comprehensive third-party warranty on each home. Homes are generally covered by a ten-year warranty for qualified and defined structural defects, one year for defects and products used, and two years for electrical, plumbing, heating, ventilation, and air conditioning parts and labor. Warranty accruals are included within accrued expenses on the consolidated balance sheets. Any legal costs associated with loss contingencies related to warranties are expensed as incurred. | | |
| Net Income Attributable to Green Brick Partners, Inc. Per Share | Net Income Attributable to Green Brick Partners, Inc. per Common Share Basic earnings per common share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during each period, adjusted for non-vested shares of restricted stock awards during each period. Net income allocated to common shareholders is net income adjusted for preferred stock dividends including dividends declared and cumulative dividends related to the current dividend period that have not been declared as of period end. Diluted earnings per share is calculated using the treasury stock method and includes the effect of all dilutive securities, including stock options and restricted stock awards. | | |
| Cost Recognition | Cost Recognition Lot acquisition, materials, direct costs, interest and indirect costs related to the acquisition, development, and construction of lots and homes are capitalized. Direct and indirect costs of developing residential lots are allocated evenly to all applicable lots. Capitalized costs of residential lots are charged to earnings when the related revenue is recognized. Non-capitalizable costs in connection with developed lots and completed homes and other selling and administrative costs are charged to earnings when incurred. | | |
| Debt Issuance Costs | Debt Issuance Costs Debt issuance costs represent costs incurred related to the senior unsecured notes and revolving secured and unsecured credit facilities, including amendments thereto, and reduce the carrying amount of debt on the consolidated balance sheets. These costs are subject to capitalization to inventory over the term of the related debt facility using the straight-line method, which approximates the effective interest rate method for our senior unsecured notes and notes payable. | | |
| Share-based Compensation | Share-Based Compensation The Company measures and accounts for share-based awards in accordance with ASC 718, Compensation - Stock Compensation . The Company expenses share-based payment awards made to employees and directors, including stock options and restricted stock awards. Share-based compensation expense associated with stock options and restricted stock awards with vesting contingent upon the achievement of service conditions is recognized on a straight-line basis, net of estimated forfeitures, over the requisite service period over which the awards are expected to vest. The Company estimates the value of stock options with vesting contingent upon the achievement of service conditions as of the date the award was granted using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the use of certain input variables, such as expected volatility, risk-free interest rate and expected award life. | | |
| Income Taxes | Income Taxes The Company accounts for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in years in which temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company regularly reviews historical and anticipated future pre-tax results of operations to determine whether we will be able to realize the benefit of deferred tax assets. A valuation allowance is required to reduce the deferred tax asset when it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized due to the lack of sufficient taxable income. The Company assesses the recoverability of deferred tax assets and the need for a valuation allowance on an ongoing basis. In making this assessment, management considers all available positive and negative evidence and available income tax planning to determine whether it is more-likely-than-not that some portion or all of the deferred tax assets will be realized in future periods. This assessment requires significant judgment and estimates involving current and deferred income taxes, tax attributes relating to the interpretation of various tax laws, historical bases of tax attributes associated with certain assets and limitations surrounding the realization of deferred tax assets. We establish accruals for uncertain tax positions that reflect our best estimate of deductions and credits that may not be sustained on a more-likely-than-not basis. We recognize interest and penalties related to uncertain tax positions in the income tax expense in the consolidated statements of income. Accrued interest and penalties, if any, are included within accrued expenses on the consolidated balance sheets. In accordance with ASC 740, Income Taxes , the Company recognizes the effect of income tax positions only if those positions have a more-likely-than-not chance of being sustained by the Company. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. | | |
| Revenue from Contract with Customer [Policy Text Block] | Revenue Recognition Contracts with Customers The Company derives revenues from two primary sources: the closing and delivery of homes through our builder operations segments and the closing of lots and land sold to third parties through our land development segment. All of our revenue is from contracts with customers. Contract Liabilities The Company requires homebuyers to submit a deposit for home purchases and requires third-party buyers to submit a deposit in connection with land sale or lot option contracts. The non-refundable deposits serve as an incentive for performance under homebuilding and land sale or development contracts. Cash received as customer deposits, if held in escrow, is reflected as restricted cash and as customer and builder deposits on the consolidated balance sheets. Performance Obligations The Company’s contracts with homebuyers contain a single performance obligation. The performance obligation is satisfied when homes are completed and control is transferred to the buyer which occurs when legal title has been transferred to the buyer. The Company does not have any variable consideration associated with home sales transactions. Revenue from mechanic’s lien contracts in which the Company serves as the general contractor for custom homes where the customer, and not the Company, owns the underlying land and improvements is recognized based on the input method, where progress toward completion is measured by relating the actual cost of work performed to date to the estimated total cost of the respective contracts. Lot option contracts contain multiple performance obligations. The performance obligations are satisfied as lots are closed and legal title has been transferred to the builder. For lot option contracts, individual performance obligations are accounted for separately. The transaction price is allocated to the separate performance obligations on a relative stand-alone selling price basis. Certain lot option contracts require escalations in lot price over the option period. Any escalator is not collectible until the lot closing occurs. While we recognize lot escalators as variable consideration within the transaction price, we do not recognize escalator revenue until a builder closes on a lot subject to an escalator as the escalator relates to general inflation and holding costs. Occasionally, the Company sells developed and undeveloped land parcels. If the land parcel is developed prior to the sale of the land, the revenue is recognized at closing since we deliver a single performance obligation in the form of a developed parcel. We also recognize revenue at closing on undeveloped land parcel sales as there are no other obligations beyond delivering the undeveloped land. Homebuyers are not obligated to pay for a home until the closing and delivery of the home. The selling price of a home is based on the contract price adjusted for any change orders, which are considered modifications of the contract price. Homebuilders are not obligated to pay for developed lots prior to control of the lots and any associated improvements being transferred to them. The term of our lot option contracts is generally based upon the number of lots being purchased and an agreed upon lot takedown schedule, which can be in excess of one year. Lots cannot be taken down until development is substantially complete. There is no significant financing component related to our third-party lot sales. The Company does not sell warranties outside of the customary workmanship warranties provided on homes or developed lots at the time of sale. The warranties offered to homebuyers are short term, with the exception of ten-year warranties on structural concerns for homes. As these are assurance-type warranties, there is no separate performance obligation related to warranties provided to homebuyers or homebuilders. Significant Judgments and Estimates There are no significant judgments involved in the recognition of residential units revenue. The performance obligation of delivering a completed home is satisfied upon the sale closing when title transfers to the buyer. There are no significant judgments involved in the recognition of land and lots revenue. The performance obligation of delivering land and lots is satisfied upon the closing of the sale when title transfers to the buyer. Contract Costs The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company pays sales commissions to employees and/or outside realtors related to individual home sales which are expensed as incurred at the time of closing. Commissions on the sale of land parcels are also expensed as incurred upon closing. Sales commissions on the sale of homes are included in the selling, general, and administrative expenses in the consolidated statements of income. The Company also pays builder incentives to employees which are based on the time it takes to build individual homes, as well as quality inspection completion and customer satisfaction. The builder incentives do not represent incremental costs that would require capitalization as we would incur these costs whether or not we sold the home. As such, we recognize builder incentives as expense at the time they are incurred and paid. Advertising costs, sales salaries and certain costs associated with model homes, such as signage, do not qualify for capitalization under ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers , as they are not incremental costs of obtaining a contract. As such, we expense these costs to selling, general and administrative expense as incurred. Costs incurred related to model home furnishings and sales office construction are capitalized and included in property and equipment, net on the consolidated balance sheets. | | |
| Selling, General and Administrative Expenses, Policy [Policy Text Block] | Selling, General and Administrative ExpenseSelling, general and administrative expense represents salaries, benefits, share-based compensation, property taxes on finished homes, sales commissions, depreciation, amortization, advertising and marketing, rent, and other administrative items, and is recorded in the period incurred. | | |
| Fair Value Measurements | Fair Value Measurements The Company has adopted and implemented the provisions of ASC 820-10, Fair Value Measurements , with respect to fair value measurements of: all elected financial assets and liabilities and any nonfinancial assets and liabilities that are recognized or disclosed in the consolidated financial statements at fair value on a recurring basis (at least annually). Under ASC 820-10, fair value is defined as an exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. These provisions establish a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of input are defined as follows: Level 1 — unadjusted quoted prices for identical assets or liabilities in active markets accessible by the Company; Level 2 — inputs that are observable in the marketplace other than those classified as Level 1; and Level 3 — inputs that are unobservable in the marketplace and significant to the valuation. Entities are encouraged to maximize the use of observable inputs and minimize the use of unobservable inputs. If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. Our valuation methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. Transfers between levels of the fair value hierarchy are deemed to have occurred on the date of the event or change in circumstances that caused the transfer. | | |
| Segment Information | Segment Information In accordance with ASC 280, Segment Reporting (“ASC 280”), an operating segment is defined as a component of an enterprise for which discrete financial information is available and reviewed regularly by the chief operating decision maker (“CODM”), or decision-making group, to evaluate performance and make operating decisions. A reportable segment is an operating segment, either separately defined or aggregated from several operating segments based on similar economic and other characteristics, that exceeds certain quantitative thresholds of ASC 280. | | |
| Business Combinations Policy [Policy Text Block] | Business Combinations Acquisitions are accounted for in accordance with ASC 805. Following the determination that control of a business and its inputs, processes and outputs were obtained in exchange for consideration, all material assets and liabilities of the business, including contingent consideration, are measured and recognized at fair value as of the date of the acquisition to reflect the purchase price. Depending on the fair value of net assets acquired, the purchase price allocation may or may not result in goodwill. Contingent consideration is subsequently remeasured to fair value at each reporting date until the contingency is resolved, with any change in fair value recognized in the consolidated statements of income. | | |
| Temporary Equity [Policy Text Block] | Redeemable Noncontrolling Interest in Equity of Consolidated SubsidiaryRedeemable noncontrolling interest in equity of consolidated subsidiary represents equity related to a put option held by a minority shareholder of a subsidiary. Based on the put option structure, the minority shareholder’s interest in the controlled subsidiary is classified as a redeemable noncontrolling interest on the consolidated balance sheets. The accretion of the redeemable noncontrolling interest to its estimated redemption value is recorded in additional paid-in capital on the consolidated balance sheets if the estimated redemption value, net of accretion, is greater than the current value of the noncontrolling interest capital account. | | |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740, Income Taxes related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2020, with early adoption permitted. The Company adopted the standard on January 1, 2021. The adoption of ASU 2019-12 had no impact on the Company’s consolidated financial statements. In June 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible | | |
| Interest Expense, Policy [Policy Text Block] | Interest Expense Interest expense consists primarily of interest costs incurred on our debt that are not capitalized, and amortization of debt issuance costs. We capitalize interest costs incurred to inventory during development and other qualifying activities. Debt issuance costs are capitalized to inventory over the term of the underlying debt using the straight-line method, which approximates the effective interest rate method for our senior unsecured notes and notes payable, in accordance with our interest capitalization policy. All interest costs were capitalized during the years ended December 31, 2021, 2020 and 2019. | | |
