| Basis of Accounting [Text Block] | Summary of Significant Accounting Policies Business. M/I Homes, Inc. and its subsidiaries (the “Company” or “we”) is engaged primarily in the construction and sale of single-family residential homes in Columbus and Cincinnati, Ohio; Indianapolis, Indiana; Chicago, Illinois; Minneapolis/St. Paul, Minnesota; Detroit, Michigan; Tampa, Orlando, Fort Myers/Naples, and Sarasota, Florida; Austin, Dallas/Fort Worth, Houston and San Antonio, Texas; Charlotte and Raleigh, North Carolina and Nashville, Tennessee. The Company designs, sells and builds single-family homes on developed lots, which it develops or purchases ready for home construction. The Company also purchases undeveloped land to develop into developed lots for future construction of single-family homes and, on a limited basis, for sale to others. Our homebuilding operations operate across two geographic regions in the United States. Within these regions, our operations have similar economic characteristics; therefore, they have been aggregated into two reportable homebuilding segments: Southern homebuilding and Northern homebuilding. The Company conducts mortgage financing activities through its 100%-owned subsidiary, M/I Financial, LLC (“M/I Financial”), which originates mortgage loans primarily for purchasers of the Company’s homes. The loans and the servicing rights are generally sold to outside mortgage lenders. The Company and M/I Financial also operate 100%-owned subsidiaries that provide title services to purchasers of the Company’s homes. Our mortgage banking and title service activities have similar economic characteristics; therefore, they have been aggregated into one reportable segment, the financial services segment. Basis of Presentation. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the accounts of M/I Homes, Inc. and those of our consolidated subsidiaries, partnerships and other entities in which we have a controlling financial interest, and of variable interest entities in which we are deemed the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from these estimates and have a significant impact on the financial condition and results of operations and cash flows. Cash, Cash Equivalents and Restricted Cash. Cash and cash equivalents are liquid investments with an initial maturity of three months or less. Amounts in transit from title companies for homes delivered are included in this balance at December 31, 2022 and 2021, respectively. Restricted cash consists of cash held in escrow. Cash, Cash Equivalents and Restricted Cash includes restricted cash balances of $1.0 million and $0.3 million at December 31, 2022 and 2021, respectively. Mortgage Loans Held for Sale. Mortgage loans held for sale consists primarily of single-family residential loans collateralized by the underlying property. Generally, all of the mortgage loans and related servicing rights are sold to third-party investors shortly after origination. Refer to the Revenue Recognition policy described below for additional discussion. Inventory. Inventory includes the costs of land acquisition, land development and home construction, capitalized interest, real estate taxes, direct overhead costs incurred during development and home construction, and common costs that benefit the entire community, less impairments, if any. Land acquisition, land development and common costs (both incurred and estimated to be incurred) are typically allocated to individual lots based on the total number of lots expected to be closed in each community or phase, or based on the relative fair value, the relative sales value or the front footage method of each lot. Any changes to the estimated total development costs of a community or phase are allocated proportionately to homes remaining in the community or phase and homes previously closed. The cost of individual lots is transferred to homes under construction when home construction begins. Home construction costs are accumulated on a specific identification basis. Costs of home deliveries include the specific construction cost of the home and the allocated lot costs. Such costs are charged to cost of sales simultaneously with revenue recognition, as discussed above. When a home is closed, we typically have not yet paid all incurred costs necessary to complete the home. As homes close, we compare the home construction budget to actual recorded costs to date to estimate the additional costs to be incurred from our subcontractors related to the home. We record a liability and a corresponding charge to cost of sales for the amount we estimate will ultimately be paid related to that home. We monitor the accuracy of such estimates by comparing actual costs incurred in subsequent months to the estimate, although actual costs to complete a home in the future could differ from our estimates. Inventory is recorded at cost, unless events and circumstances indicate that the carrying value of the inventory is impaired, at which point the inventory is written down to fair value as required by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360-10, Property, Plant and Equipment (“ASC 360”). The Company assesses inventory for recoverability on a quarterly basis to determine if events or changes in local or national economic conditions indicate that the carrying amount of an asset may not be recoverable. In conducting our quarterly review for indicators of impairment on a community level, we evaluate, among other things, the margins on sales contracts in backlog, the margins on homes that have been delivered, expected changes in margins with regard to future home sales over the life of the community, expected changes in margins with regard to future land sales, the value of the land itself as well as any results from third party appraisals. We pay particular attention to communities in which inventory is moving at a slower than anticipated absorption pace, and communities whose average sales price and/or margins are trending downward and are anticipated to continue to trend downward. We also evaluate communities where management intends to lower the sales price or offer incentives in order to improve absorptions even if the community’s historical results do not indicate a potential for impairment. From the review of all of these factors, we identify communities whose carrying values may exceed their estimated undiscounted future cash flows and run a test for recoverability. For those communities whose carrying values exceed the estimated undiscounted future cash flows and which are deemed to be impaired, the impairment recognized is measured by the amount by which the carrying amount of the communities exceeds the estimated fair value. Due to the fact that the Company’s cash flow models and estimates of fair values are based upon management estimates and assumptions, unexpected changes in market conditions and/or changes in management’s intentions with respect to the inventory may lead the Company to incur additional impairment charges in the future. Our determination of fair value is based on projections and estimates, which are Level 3 measurement inputs. Because each inventory asset is unique, there are numerous inputs and assumptions used in our valuation techniques, including estimated average selling price, construction and development costs, absorption pace (reflecting any product mix change strategies implemented or to be implemented), selling strategies, alternative land uses (including disposition of all or a portion of the land owned), or discount rates, which could materially impact future cash flow and fair value estimates. If communities are not recoverable based on estimated future undiscounted cash flows, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. The fair value of a community is estimated by discounting management’s cash flow projections using an appropriate risk-adjusted interest rate. As of both December 31, 2022 and December 31, 2021, we utilized discount rates ranging from 13% to 16% in our valuations. The discount rate used in determining each asset’s estimated fair value reflects the inherent risks associated with the related estimated cash flow stream, as well as current risk-free rates available in the market and estimated market risk premiums. For example, construction in progress inventory, which is closer to completion, will generally require a lower discount rate than land under development in communities consisting of multiple phases spanning several years of development. During the fourth quarter of 2022, we recorded an aggregate loss of $18.4 million that included $10.2 million of write-offs of land deposits for land we no longer intend to purchase in order to right-size our land portfolio and $8.2 million of asset impairment charges. Our quarterly assessments reflect management’s best estimates. Due to the inherent uncertainties in management’s estimates and uncertainties related to our operations and our industry as a whole, we are unable to determine at this time if and to what extent continuing future impairments will occur. Additionally, due to the volume of possible outcomes that can be generated from changes in the various model inputs for each community, we do not believe it is possible to create a sensitivity analysis that can provide meaningful information for the users of our consolidated financial statements. Further details relating to our assessment of inventory for recoverability are included in Note 3 to our Consolidated Financial Statements. Property and Equipment-net. The Company records property and equipment at cost and subsequently depreciates the assets using both straight-line and accelerated methods. Following are the major classes of depreciable assets and their estimated useful lives: Year Ended December 31, (In thousands) 2022 2021 Office furnishings, leasehold improvements, computer equipment and computer software $ 38,489 $ 38,178 Transportation and construction equipment 20,735 20,540 (a) Property and equipment 59,224 58,718 Accumulated depreciation (21,778) (21,070) Property and equipment, net $ 37,446 $ 37,648 Estimated Useful Lives Office furnishings, leasehold improvements, computer equipment and computer software 3-7 years Transportation and construction equipment (a) 5-25 years (a) During the fourth quarter of 2021, the Company sold its airplane and purchased another airplane for a net change in asset value of $10.5 million. The asset is included in the table above within Transportation and construction equipment and within Property and Equipment - Net on our Consolidated Balance Sheet. Depreciation is computed using the straight-line method over the respective estimated useful lives of the parts of the airplane. Maintenance and repair expenditures are charged to selling, general and administrative expense as incurred. The sale of the airplane was with an unrelated party and resulted in a gain of $1.9 million that is included in Other income on the Company’s Consolidated Statement of Operations. Depreciation expense was $8.4 million, $7.5 million and $6.8 million in 2022, 2021 and 2020, respectively. Goodwill. Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired and liabilities assumed in business combinations. As a result of the Company’s acquisition of the homebuilding assets and operations of Pinnacle Homes in Detroit, Michigan on March 1, 2018, the Company recorded goodwill of $16.4 million, which is included as Goodwill in our Consolidated Balance Sheets. This amount was based on the estimated fair values of the acquired assets and assumed liabilities at the date of the acquisition in accordance with ASC 350, Intangibles, Goodwill and Other (“ASC 350”). The Company performed its annual goodwill impairment analysis during the fourth quarter of 2022, and no impairment was recorded at December 31, 2022. See Note 12 to the Company’s Consolidated Financial Statements for further discussion. Other Assets. Other assets at December 31, 2022 and 2021 consisted of the following: Year Ended December 31, (In thousands) 2022 2021 Development reimbursement receivable from local municipalities $ 57,078 $ 29,062 Mortgage servicing rights 15,813 8,361 Prepaid expenses 18,258 15,591 Prepaid acquisition costs 5,737 8,186 Other 51,519 41,826 Total other assets $ 148,405 $ 103,026 Warranty Reserves. We use subcontractors for nearly all aspects of home construction. Although our subcontractors are generally required to repair and replace any product or labor defects, we are, during applicable warranty periods, ultimately responsible to the homeowner for making such repairs. As such, we record warranty reserves to cover our exposure to the costs for materials and labor not expected to be covered by our subcontractors to the extent they relate to warranty-type claims. Warranty reserves are established by charging cost of sales and crediting a warranty reserve for each home delivered. The amounts charged are estimated by management to be adequate to cover expected warranty-related costs under the Company’s warranty programs. Warranty reserves are recorded for warranties under our Home Builder’s Limited Warranty (“HBLW”) and our transferable structural warranty (see additional information in Note 8 to our Consolidated Financial Statements). The warranty reserves for the HBLW are established as a percentage of average sales price and adjusted based on historical payment patterns determined, generally, by geographic area and recent trends. Factors that are given consideration in determining the HBLW reserves include: (1) the historical range of amounts paid per average sales price on a home; (2) type and mix of amenity packages added to the home; (3) any warranty expenditures not considered to be normal and recurring; (4) timing of payments; (5) improvements in quality of construction expected to impact future warranty expenditures; and (6) conditions that may affect certain projects and require a different percentage of average sales price for those specific projects. Changes in estimates for warranties occur due to changes in the historical payment experience and differences between the actual payment pattern experienced during the period and the historical payment pattern used in our evaluation of the warranty reserve balance at the end of each quarter. Actual future warranty costs could differ from our current estimated amount. Our warranty reserves for our transferable structural warranty programs are established on a per-unit basis. While the structural warranty reserve is recorded as each house is delivered, the sufficiency of the structural warranty per unit charge and total reserve is re-evaluated on an annual basis, with the assistance of an actuary, using our own historical data and trends, industry-wide historical data and trends, and other project specific factors. The reserves are also evaluated quarterly and adjusted if we encounter activity that is inconsistent with the historical experience used in the annual analysis. These reserves are subject to variability due to uncertainties regarding structural defect claims for products we build, the markets in which we build, claim settlement history, insurance and legal interpretations, among other factors. Our warranty reserve amounts are based upon historical experience and geographic location. While we believe that our warranty reserves are sufficient to cover our projected costs, there can be no assurances that historical data and trends will accurately predict our actual warranty costs. At December 31, 2022 and 2021, warranty reserves of $32.9 million and $29.7 million, respectively, are included in Other Liabilities on the Consolidated Balance Sheets. See Note 8 to our Consolidated Financial Statements for additional information related to our warranty reserves, including reserves related to stucco-related repairs in certain of our Florida communities. Self-insurance Reserves. Self-insurance reserves are made for estimated liabilities associated with employee health care, workers’ compensation, and general liability insurance. Our workers’ compensation claims are insured by a third party. The reserves related to employee health care and workers’ compensation are based on historical experience and open case reserves. Our general liability claims are insured by a third party, subject to a self-insured retention (“SIR”). The Company records a reserve for general liability claims falling below the Company’s SIR. The reserve estimate is based on an actuarial evaluation of our past history of general liability claims, other industry specific factors and specific event analysis. At December 31, 2022 and 2021, self-insurance reserves of $3.2 million and $2.9 million, respectively, are included in Other Liabilities on the Consolidated Balance Sheets. The Company recorded expenses totaling $10.9 million, $11.4 million and $10.1 million for all self-insured and general liability claims during the years ended December 31, 2022, 2021 and 2020, respectively. Other Liabilities. Other liabilities at December 31, 2022 and 2021 consisted of the following: Year Ended December 31, (In thousands) 2022 2021 Accruals related to land development $ 119,965 $ 90,786 Warranty 32,902 29,728 Payroll and other benefits 59,409 51,724 Other 63,941 54,731 Total other liabilities $ 276,217 $ 226,969 Revenue Recognition. Revenue and the related profit from the sale of a home and revenue and the related profit from the sale of land to third parties are recognized in the financial statements on the date of closing if delivery has occurred, title has passed to the buyer, all performance obligations (as defined below) have been met, and control of the home or land is transferred to the buyer in an amount that reflects the consideration we expect to be entitled to receive in exchange for the home or land. If not received immediately upon closing, cash proceeds from home closings are held in escrow for the Company’s benefit, typically for up to three days, and are included in Cash, cash equivalents and restricted cash on the Consolidated Balance Sheets. Sales incentives vary by type of incentive and by amount on a community-by-community and home-by-home basis. The costs of any sales incentives in the form of free or discounted products and services provided to homebuyers are reflected in Land and housing costs in the Consolidated Statements of Income because such incentives are identified in our home purchase contracts with homebuyers as an intrinsic part of our single performance obligation to deliver and transfer title to their home for the transaction price stated in the contracts. Sales incentives that we may provide in the form of closing cost allowances are recorded as a reduction of housing revenue at the time the home is delivered. We record sales commissions within Selling expenses in the Consolidated Statements of Income when incurred (i.e., when the home is delivered) as the amortization period is generally one year or less and therefore capitalization is not required as part of the practical expedient for incremental costs of obtaining a contract. Contract liabilities include customer deposits related to sold but undelivered homes. Substantially all of our home sales are scheduled to close and be recorded to revenue within one year from the date of receiving a customer deposit. Contract liabilities expected to be recognized as revenue, excluding revenue pertaining to contracts that have an original expected duration of one year or less, is not material. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. All of our home purchase contracts have a single performance obligation as the promise to transfer the home is not separately identifiable from other promises in the contract and, therefore, not distinct. Our performance obligation, to deliver the agreed-upon home, is generally satisfied in less than one year from the original contract date. Deferred revenue resulting from uncompleted performance obligations existing at the time we deliver new homes to our homebuyers is not material. Although our third party land sale contracts may include multiple performance obligations, the revenue we expect to recognize in any future year related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less, is not material. We do not disclose the value of unsatisfied performance obligations for land sale contracts with an original expected duration of one year or less. We recognize the majority of the revenue associated with our mortgage loan operations when the mortgage loans are sold and/or related servicing rights are sold to third party investors or retained and managed under a third party sub-service arrangement. The revenue recognized is reduced by the fair value of the related guarantee provided to the investor. The fair value of the guarantee is recognized in revenue when the Company is released from its obligation under the guarantee (note that guarantees are excluded from the scope of ASC 606). As of December 31, 2022 and 2021, we retained mortgage servicing rights of 3,787 and 2,004 loans, respectively, for a total value of $15.8 million and $8.4 million, respectively. We recognize financial services revenue associated with our title operations as homes are delivered, closing services are rendered, and title policies are issued, all of which generally occur simultaneously as each home is delivered. All of the underwriting risk associated with title insurance policies is transferred to third-party insurers. The following table presents our revenues disaggregated by revenue source: Year Ended December 31, (Dollars in thousands) 2022 2021 2020 Housing $ 4,010,427 $ 3,630,469 $ 2,939,962 Land sales 34,771 13,390 19,170 Financial services (a) 86,195 102,028 87,013 Total revenue $ 4,131,393 $ 3,745,887 $ 3,046,145 (a) Revenues include hedging gains of $49.4 million for the year ended December 31, 2022, hedging gains of $1.6 million for the year ended December 31, 2021, and hedging losses of $19.0 million for the year ended December 31, 2020. Hedging gains (losses) do not represent revenues recognized from contracts with customers. Refer to Note 15 for presentation of our revenues disaggregated by geography. As our homebuilding operations accounted for over 97% of our total revenues for the years ended December 31, 2022, 2021 and 2020, with most of those revenues generated from home purchase contracts with customers, we believe the disaggregation of revenues as disclosed above and in Note 15 fairly depict how the nature, amount, timing and uncertainty of cash flows are affected by economic factors. Land and Housing Cost of Sales. All associated homebuilding costs are charged to cost of sales in the period when the revenues from home deliveries are recognized. Homebuilding costs include: land and land development costs; home construction costs (including an estimate of the costs to complete construction); previously capitalized interest; real estate taxes; indirect costs; and estimated warranty costs. All other costs are expensed as incurred. Sales incentives, including pricing discounts and financing costs paid by the Company, are recorded as a reduction of revenue in the Company’s Consolidated Statements of Income. Sales incentives in the form of options or upgrades are recorded in homebuilding costs. Income Taxes. The Company records income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized based on future tax consequences attributable to (1) temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and (2) operating loss and tax credit carryforwards, if any. Deferred tax assets and liabilities are measured using enacted tax rates in effect in the years in which those temporary differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period when the change is enacted. In accordance with ASC 740-10, Income Taxes (“ASC 740”) , we evaluate the realizability of our deferred tax assets, including the benefit from net operating losses (“NOLs”) and tax credit carryforwards, if any, to determine if a valuation allowance is required based on whether it is more likely than not (a likelihood of more than 50%) that all or any portion of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is primarily dependent upon the generation of future taxable income. In determining the future tax consequences of events that have been recognized in the consolidated financial statements or tax returns, judgment is required. This assessment gives appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets and considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the length of statutory carryforward periods, our experience with operating losses and our experience of utilizing tax credit carryforwards and tax planning alternatives. See Note 14 to our Consolidated Financial Statements for more information regarding our deferred tax assets. Earnings Per Share. The Company computes earnings per share in accordance with ASC 260, Earnings per Share , (“ASC 260”). Basic earnings per share is calculated by dividing income attributable to common shareholders by the weighted average number of common shares outstanding during each year. Diluted earnings per share gives effect to the potential dilution that could occur if securities or contracts to issue our common shares that are dilutive were exercised or converted into common shares or resulted in the issuance of common shares that then shared our earnings. In periods of net losses, no dilution is computed. See Note 13 to our Consolidated Financial Statements for more information regarding our earnings per share calculation. Recently Adopted Accounting Standards. In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 is intended to provide temporary optional expedients and exceptions to the US GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance became effective on March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”), which clarified the scope and application of the original guidance. We fully adopted ASU 2020-04 and ASU 2021-01 in October 2022 after we amended our $90 million mortgage repurchase agreement, dated October 30, 2017, as amended (the “MIF Mortgage Repurchase Facility”), which discontinued the use of LIBOR and replaced it with One-Month Term SOFR. The adoption of this guidance did not have a material impact on our consolidated financial statements and disclosures. |
