Basis of Presentation [Abstract]
Basis of Accounting [Text Block]	The accompanying Unaudited Condensed Consolidated Financial Statements (the “financial statements”) of M/I Homes, Inc. and its subsidiaries (the “Company”) and notes thereto have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. The financial statements include the accounts of the Company. All intercompany transactions have been eliminated. Results for the interim period are not necessarily indicative of results for a full year. In the opinion of management, the accompanying financial statements reflect all adjustments (all of which are normal and recurring in nature) necessary for a fair presentation of financial results for the interim periods presented. These financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 Form 10-K”). The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“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 financial statements and the reported amounts of revenues and expenses during that period. Actual results could differ from these estimates and have a significant impact on the financial condition and results of operations and cash flows. With regard to the Company, estimates and assumptions are inherent in calculations relating to valuation of inventory and investment in unconsolidated joint ventures, property and equipment depreciation, valuation of derivative financial instruments, accounts payable on inventory, accruals for costs to complete inventory, accruals for warranty claims, accruals for self-insured general liability claims, litigation, accruals for health care and workers’ compensation, accruals for guaranteed or indemnified loans, stock-based compensation expense, income taxes, and contingencies. Items that could have a significant impact on these estimates and assumptions include the risks and uncertainties listed in “Item 1A. Risk Factors” in Part I of our 2025 Form 10-K, as the same may be updated from time to time in our subsequent filings with the SEC. Impact of New Accounting Standards In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses (“ASU 2024-03”). ASU 2024-03 requires disclosure of certain costs and expenses on an interim and annual basis in the notes to the financial statements. ASU 2024-03 will be effective for the annual reporting periods in fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027. The Company is currently evaluating the impact the adoption of ASU 2024-03 may have on our consolidated financial statements and disclosures. Significant Accounting Policies There have been no significant changes to our significant accounting policies during the quarter ended March 31, 2026 as compared to those disclosed in our 2025 Form 10-K.
