Summary of Significant Accounti

Accounting Policies [Abstract]
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 and Sarasota, Florida; Austin, Dallas/Fort Worth, Houston and San Antonio, Texas; Charlotte and Raleigh, North Carolina; and the Virginia and Maryland suburbs of Washington, D.C. 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 three geographic regions in the United States. Within these regions, our operations have similar economic characteristics; therefore, they have been aggregated into three reportable homebuilding segments: Midwest homebuilding, Southern homebuilding and Mid-Atlantic 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% and majority-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 disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. 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, 2018 and 2017 , respectively. Restricted cash consists of amounts held in restricted accounts as collateral for letters of credit as well as cash held in escrow. Cash, Cash Equivalents and Restricted Cash includes restricted cash balances of $0.7 million and $1.0 million at December 31, 2018 and 2017 , 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 land 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, 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. As of December 31, 2018 , our projections generally assume a gradual improvement in market conditions over time. 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, 2018 and December 31, 2017 , 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. 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. Capitalized Interest. The Company capitalizes interest during land development and home construction. Capitalized interest is charged to cost of sales as the related inventory is delivered to a third party. The summary of capitalized interest for the years ended December 31, 2018, 2017 and 2016 is as follows: Year Ended December 31, (In thousands) 2018 2017 2016 Capitalized interest, beginning of period $ 17,169 $ 16,012 $ 16,740 Interest capitalized to inventory 29,053 21,484 17,685 Capitalized interest charged to cost of sales (25,457 ) (20,327 ) (18,413 ) Capitalized interest, end of year $ 20,765 $ 17,169 $ 16,012 Interest incurred $ 49,537 $ 40,358 $ 35,283 Investment in Joint Venture Arrangements. In order to minimize our investment and risk of land exposure in a single location, we have periodically partnered with other land developers or homebuilders to share in the land investment and development of a property through joint ownership and development agreements, joint ventures, and other similar arrangements. During 2018 , we increased our total investment in such joint venture arrangements by $15.4 million from $20.5 million at December 31, 2017 to $35.9 million at December 31, 2018 , which was driven primarily by our cash contributions to our joint venture arrangements during 2018 of $31.9 million , offset, in part, by our lot distributions from our joint venture arrangements during 2018 of $16.2 million . We believe that the Company’s maximum exposure related to its investment in these joint venture arrangements as of December 31, 2018 is the amount invested of $35.9 million , which is reported as Investment in Joint Venture Arrangements on our Consolidated Balance Sheets, although we expect to invest further amounts in these joint venture arrangements as development of the properties progresses. Further details relating to our joint venture arrangements are included in Note 6 to our Consolidated Financial Statements. We use the equity method of accounting for investments in joint venture arrangements over which we exercise significant influence but do not have a controlling interest. Under the equity method, our share of the joint venture arrangements’ earnings or loss, if any, is included in our Consolidated Statements of Income. The Company assesses its investments in joint venture arrangements for recoverability on a quarterly basis in accordance with ASC 323, Investments - Equity Method and Joint Ventures (“ASC 323”) as described below. If the fair value of the investment is less than the investment’s carrying value, and the Company has determined that the decline in value is other than temporary, the Company would write down the value of the investment to its estimated fair value. The determination of whether an investment’s fair value is less than the carrying value requires management to make certain assumptions regarding the amount and timing of future contributions to the joint venture arrangements, the timing of distribution of lots to the Company from the joint venture arrangements, the projected fair value of the lots at the time of distribution to the Company, and the estimated proceeds from, and timing of, the sale of land or lots to third parties. In determining the fair value of investments in joint venture arrangements, the Company evaluates the projected cash flows associated with each joint venture arrangement. As of both December 31, 2018 and December 31, 2017 , the Company used a discount rate of 16% in determining the fair value of investments in joint venture arrangements. In addition to the assumptions management must make to determine if the investment’s fair value is less than the carrying value, management must also use judgment in determining whether the impairment is other than temporary. The factors management considers are: (1) the length of time and the extent to which the market value has been less than cost; (2) the financial condition and near-term prospects of the joint venture arrangement; and (3) the intent and ability of the Company to retain its investment in the joint venture arrangements for a period of time sufficient to allow for any anticipated recovery in market value. Due to uncertainties in the estimation process and the significant volatility in demand for new housing, actual results could differ significantly from such estimates. For joint venture arrangements where a special purpose entity is established to own the property, we generally enter into limited liability company or similar arrangements (“LLCs”) with the other partners. The Company’s ownership in these LLCs as of both December 31, 2018 and December 31, 2017 ranged from 25% to 97% . These entities typically engage in land development activities for the purpose of distributing or selling developed lots to the Company and its partners in the LLC. Variable Interest Entities. With respect to our investments in LLCs, we are required, under ASC 810-10, Consolidation (“ASC 810”), to evaluate whether or not such entities should be consolidated into our consolidated financial statements. We initially perform these evaluations when each new entity is created and upon any events that require reconsideration of the entity. In order to determine if we should consolidate an LLC, we determine (1) if the LLC is a variable interest entity (“VIE”) and (2) if we are the primary beneficiary of the entity. To determine whether we are the primary beneficiary of an entity, we consider whether we have the ability to control the activities of the VIE that most significantly impact its economic performance. This analysis considers, among other things, whether we have: the ability to determine the budget and scope of land development work, if any; the ability to control financing decisions for the VIE; the ability to acquire additional land into the VIE or dispose of land in the VIE not under contract with M/I Homes; and the ability to change or amend the existing option contract with the VIE. If we determine that we are not able to control such activities, we are not considered the primary beneficiary of the VIE. As of December 31, 2018 and December 31, 2017, we have determined that no LLC in which we have an interest met the requirements of a VIE. Land Option Agreements. In the ordinary course of business, the Company enters into land option or purchase agreements for which we generally pay non-refundable deposits. Pursuant to these land option agreements, the Company provides a deposit to the seller as consideration for the right to purchase land at different times in the future, usually at predetermined prices. In accordance with ASC 810, we analyze our land option or purchase agreements to determine whether the corresponding land sellers are VIEs and, if so, whether we are the primary beneficiary, using an analysis similar to that described above. Although we do not have legal title to the optioned land, ASC 810 requires a company to consolidate a VIE if the company is determined to be the primary beneficiary. In cases where we are the primary beneficiary, even though we do not have title to such land, we are required to consolidate these purchase/option agreements and reflect such assets and liabilities as Consolidated Inventory not Owned in our Consolidated Balance Sheets. At both December 31, 2018 and 2017 , we have concluded that we were not the primary beneficiary of any VIEs from which we are purchasing land under option or purchase agreements. In addition, we evaluate our land option or purchase agreements to determine for each contract if (1) a portion or all of the purchase price is a specific performance requirement, or (2) the amount of deposits and prepaid acquisition and development costs exceed certain thresholds relative to the remaining purchase price of the lots. If either is the case, then the remaining purchase price of the lots (or the specific performance amount, if applicable) is recorded as an asset and liability in Consolidated Inventory Not Owned (as further described below) on our Consolidated Balance Sheets. Other than as described below in “Consolidated Inventory Not Owned,” the Company currently believes that its maximum exposure as of December 31, 2018 related to our land option agreements is equal to the amount of the Company’s outstanding deposits and prepaid acquisition costs, which totaled $55.0 million , including cash deposits of $33.7 million , prepaid acquisition costs of $7.9 million , letters of credit of $9.9 million and $3.5 million of other non-cash deposits. Consolidated Inventory Not Owned and Related Obligation . At December 31, 2018 and December 31, 2017 , Consolidated Inventory Not Owned was $19.3 million and $21.5 million , respectively. At December 31, 2018 and 2017 , the corresponding liability of $19.3 million and $21.5 million , respectively, has been classified as Obligation for Consolidated Inventory Not Owned on the Consolidated Balance Sheets. The decrease in this balance from December 31, 2017 is related primarily to a decrease in the number of land purchase agreements that had deposits and prepaid acquisition and development costs that exceeded certain thresholds resulting in the remaining purchase price of the lots to be recorded in inventory not owned, partially offset by an increase in the aggregate purchase amount of land contracts with specific performance requirements. 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) 2018 2017 Land, building and improvements $ 11,824 (a) $ 11,823 Office furnishings, leasehold improvements, computer equipment and computer software 29,920 30,409 Transportation and construction equipment 10,064 10,067 Property and equipment 51,808 52,299 Accumulated depreciation (22,413 ) (25,483 ) Property and equipment, net $ 29,395 $ 26,816 (a) Includes the Company’s home office building in Columbus, Ohio that met the sale classification criteria for the period ended September 30, 2018 as it was being actively marketed. The carrying value of the building as of December 31, 2018 was $5.6 million . The Company measures assets held for sale at fair value on a nonrecurring basis and records impairment charges when the assets are deemed to be impaired. Assets held for sale are reported at the lower of cost or fair value. Costs to sell are accrued separately. The Company estimated the fair value of the building using the market values for similar properties, and the building was considered a Level 2 asset as defined in ASC 820, “Fair Value Measurements.” During the twelve months ended December 31, 2018 , the Company did not record any impairment charges on its asset held for sale. Estimated Useful Lives Building and improvements 35 years Office furnishings, leasehold improvements, computer equipment and computer software 3-7 years Transportation and construction equipment 5-25 years Depreciation expense was $5.6 million , $4.1 million and $3.6 million in 2018, 2017 and 2016 , 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 as of December 31, 2018 , 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”). Please see Note 12 to the Company’s Consolidated Financial Statements for further discussion. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which eliminates Step 2 from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. As a result of ASU 2017-04, the Company will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. ASU 2017-04 is effective beginning January 1, 2020, with early adoption permitted, and applied prospectively. The Company elected to early adopt this ASU effective for the fiscal year ended December 31, 2018 in its impairment testing and analyses. The adoption of ASU 2017-04 on January 1, 2018 did not have an impact on the Company’s consolidated financial statements and disclosures. The Company performed its annual goodwill impairment analysis during the fourth quarter of 2018, and as no indicators for impairment existed at December 31, 2018 , no impairment was recorded. In accordance with ASC 350, the Company analyzes goodwill for impairment on an annual basis (or more often if indicators of impairment exist). The Company performs a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. When performing a qualitative assessment, the Company evaluates qualitative factors such as (1) macroeconomic conditions, such as a deterioration in general economic conditions; (2) industry and market considerations, such as deterioration in the environment in which the entity operates; (3) cost factors, such as increases in raw materials and labor costs; and (4) overall financial performance, such as negative or declining cash flows or a decline in actual or planned revenue or earnings, to determine if it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, then a quantitative assessment is performed to determine the reporting unit’s fair value. If the reporting unit’s carrying value exceeds its fair value, then an impairment loss is recognized for the amount of the excess of the carrying amount over the reporting unit’s fair value. The evaluation of goodwill for possible impairment includes estimating fair value using one or a combination of valuation techniques, such as discounted cash flows. These valuations require the Company to make estimates and assumptions regarding future operating results, cash flows, changes in capital expenditures, selling prices, profitability, and the cost of capital. Although the Company believes its assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce a materially different result. Other Assets. Other assets at December 31, 2018 and 2017 consisted of the following:. Year Ended December 31, (In thousands) 2018 2017 Development reimbursement receivable from local municipalities $ 13,632 $ 14,981 Mortgage servicing rights 6,477 7,821 Prepaid expenses 8,605 9,022 Prepaid acquisition costs 7,873 5,634 Other 24,207 23,677 Total other assets $ 60,794 $ 61,135 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 (as described further in Note 8 to our Consolidated Financial Statements) under the Company’s warranty programs. Warranty reserves are recorded for warranties under our Home Builder’s Limited Warranty (“HBLW”) and our 30-year (offered on all homes sold after April 25, 1998 and on or before December 1, 2015 in all of our markets except our Texas markets), 15-year (offered on all homes sold after December 1, 2015 in all of our markets except our Texas markets) and 10-year (offered on all homes sold in our Texas markets) transferable structural warranty. 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 home 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, 2018 and 2017 , warranty reserves of $26.5 million and $26.1 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. Please 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. For 2018 , our self-insurance limit for employee health care was $250,000 per covered person per contract period, with stop loss insurance covering amounts in excess of $250,000 . In 2019, our stop loss insurance will now cover amounts in excess of $275,000 . Our workers’ compensation claims are insured by a third party and carry a deductible of $250,000 per claim, except for workers compensation claims made in the State of Ohio where the Company is self-insured. Our self-insurance limit for Ohio workers’ compensation is $500,000 per claim, with stop loss insurance covering all amounts in excess of this limit. 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 deductible. Effective for home closings occurring on or after July 1, 2017, the Company renewed its general liability insurance coverage which, among other things, changed the structure of our completed operations/construction defect deductible to $10.0 million for the Company (for closings prior to July 1, 2017, our completed operations/construction defect deductible was $7.5 million for each of our regions) and decreased our third party bodily injury and property damage claims deductible to $250,000 (a decrease from $500,000 for closings prior to July 1, 2017). The Company records a reserve for general liability claims falling below the Company’s deductible. 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, 2018 and 2017 , self-insurance reserves of $2.7 million and $2.4 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. The Company recorded expenses totaling $9.2 million , $8.9 million and $6.5 million for all self-insured and general liability claims during the years ended December 31, 2018, 2017 and 2016 , respectively. Guarantees and Indemnities. Guarantee and indemnity liabilities are established by charging the applicable income statement or balance sheet line, depending on the nature of the guarantee or indemnity, and crediting a liability. M/I Financial provides a limited-life guarantee on loans sold to certain third parties and estimates its actual liability related to the guarantee and any indemnities subsequently provided to the purchaser of the loans in lieu of loan repurchase based on historical loss experience. Actual future costs associated with loans guaranteed or indemnified could differ materially from our current estimated amounts. The Company has also provided certain other guarantees and indemnities in connection with the purchase and development of land, including environmental indemnities, and guarantees of the completion of land development. The Company estimates these liabilities based on the estimated cost of insurance coverage or estimated cost of acquiring a bond in the amount

Stock Based Compensation

Stock Based Compensation	12 Months Ended

Stock Based Compensation [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Stock-Based and Deferred Compensation Stock Incentive Plans At our 2018 Annual Meeting of Shareholders, our shareholders approved the M/I Homes, Inc. 2018 Long-Term Incentive Plan (the “2018 LTIP”), an equity compensation plan administered by the Compensation Committee of our Board of Directors. Under the 2018 LTIP, the Company is permitted to grant (1) nonqualified stock options to purchase common shares, (2) incentive stock options to purchase common shares, (3) stock appreciation rights, (4) restricted common shares, (5) other stock-based awards – awards that are valued in whole or in part by reference to, or otherwise based on, the fair market value of our common shares, and (6) cash-based awards to its officers, employees, non-employee directors and other eligible participants. Subject to certain adjustments, the plan authorizes awards to officers, employees, non-employee directors and other eligible participants for up to 2,250,000 common shares, of which 2,221,500 remain available for grant at December 31, 2018 . The 2018 LTIP replaced the M/I Homes, Inc. 2009 Long-Term Incentive Plan (the “2009 LTIP”), which plan was terminated immediately following our 2018 Annual Meeting of Shareholders. The 2009 LTIP replaced the 1993 Stock Incentive Plan as Amended (the “1993 Plan”), which expired by its terms on April 22, 2009. Awards outstanding under the 2009 LTIP and the 1993 Plan remain in effect in accordance with their respective terms. Stock Options Stock options are granted at the market price of the Company’s common shares at the close of business on the date of grant. Options awarded generally vest 20% annually over five years and expire after ten years. Under the 2018 LTIP and the 2009 LTIP, in the case of termination due to death, disability or retirement, all options will become immediately exercisable. Shares issued upon option exercise may consist of treasury shares, authorized but unissued common shares or common shares purchased by or on behalf of the Company in the open market. Following is a summary of stock option activity for the year ended December 31, 2018 , relating to the stock options awarded under the 2018 LTIP, the 2009 LTIP and the 1993 Plan: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (a) (In thousands) Options outstanding at December 31, 2017 1,822,818 $ 20.48 6.88 $ 25,376 Granted 438,500 31.89 Exercised (38,628 ) 13.92 Forfeited (10,000 ) 28.49 Options outstanding at December 31, 2018 2,212,690 $ 22.82 6.58 $ 3,123 Options vested or expected to vest at December 31, 2018 2,151,750 $ 22.74 6.53 $ 3,073 Options exercisable at December 31, 2018 1,400,490 $ 21.22 5.65 $ 2,486 (a) Intrinsic value is defined as the amount by which the fair value of the underlying common shares exceeds the exercise price of the option. The aggregate intrinsic value of options exercised during the years ended December 31, 2018, 2017 and 2016 was $0.6 million , $9.3 million and $0.1 million , respectively. The fair value of our five-year service-based stock options granted during the years ended December 31, 2018, 2017 and 2016 was established at the date of grant using the Black-Scholes pricing model, with the weighted average assumptions as follows: Year Ended December 31, 2018 2017 2016 Risk-free interest rate 2.72 % 1.96 % 1.34 % Expected volatility 32.01 % 39.49 % 47.20 % Expected term (in years) 5.7 5.9 5.7 Weighted average grant date fair value of options granted during the period $ 11.31 $ 9.45 $ 7.57 The risk-free interest rate is based upon the U.S. Treasury constant maturity rate at the date of the grant. Expected volatility is based on an average of (1) historical volatility of the Company’s stock and (2) implied volatility from traded options on the Company’s stock. The risk-free rate for periods within the contractual life of the stock option award is based on the yield curve of a zero-coupon U.S. Treasury bond on the date the stock option award is granted, with a maturity equal to the expected term of the stock option award granted. The Company uses historical data to estimate stock option exercises and forfeitures within its valuation model. The expected life of stock option awards granted is derived from historical exercise experience under the Company’s share-based payment plans, and represents the period of time that stock option awards granted are expected to be outstanding. Total stock-based compensation expense related to stock option awards that has been charged against income relating to the 2018 LTIP, the 2009 LTIP and the 1993 Plan was $3.9 million , $3.7 million , and $3.3 million for the years ended December 31, 2018, 2017 and 2016 , respectively. As of December 31, 2018 , there was a total of $7.7 million of unrecognized compensation expense related to unvested stock option awards that will be recognized as stock-based compensation expense as the awards vest over a weighted average period of 2.1 years for the service awards. Director Stock Units The Company awarded its non-employee directors a total of 21,000 stock units under the 2018 LTIP during the year ended December 31, 2018 and a total of 18,000 and 15,000 stock units under the 2009 LTIP during the years ended December 31, 2017 and 2016 , respectively. Each stock unit is the equivalent of one common share, vests immediately and will be converted into a common share upon termination of service as a director. The Company recognized the full stock-based compensation expense related to the awards of $0.7 million , $0.5 million and $0.3 million in 2018 , 2017 and 2016 , respectively, due to the immediate vesting provisions of the award. On May 5, 2009, the Company’s board of directors terminated the M/I Homes, Inc. 2006 Director Equity Incentive Plan (the “Director Equity Plan”). Awards outstanding under the Director Equity Plan remain in effect in accordance with their respective terms. At December 31, 2018 , there were 8,059 stock units outstanding under the Director Equity Plan with a value of $0.2 million . Performance Share Unit Awards On February 15, 2018 , February 8, 2017 and February 16, 2016 , the Company awarded its executive officers (in the aggregate) a target number of performance share units (“PSU’s”) under the 2009 LTIP equal to 46,444 , 57,110 and 79,108 PSU’s, respectively. Each PSU represents a contingent right to receive one common share of the Company if vesting is satisfied at the end of a three-year performance period (the “Performance Period”). The ultimate number of PSU’s that will vest and be earned, if any, after the completion of the Performance Period, is based on (1) (a) the Company’s cumulative annual pre-tax income from operations, excluding extraordinary items as defined in the underlying award agreements with the executive officers, over the Performance Period (weighted 80% ) (the “Performance Condition”), and (b) the Company’s relative total shareholder return over the Performance Period compared to the total shareholder return of a peer group of other publicly-traded homebuilders (weighted 20% ) (the “Market Condition”) and (2) the participant’s continued employment through the end of the Performance Period, except in the case of termination due to death, disability or retirement or involuntary termination without cause by the Company. The number of PSU’s that vest may increase by up to 50% from the target number based on levels of achievement of the above criteria as set forth in the applicable award agreements and decrease to zero if the Company fails to meet the minimum performance levels for both of the above criteria. If the Company achieves the minimum performance levels for both of the above criteria, 50% of the target number of PSU’s will vest and be earned. Any portion of PSU’s that does not vest at the end of the Performance Period will be forfeited. Additionally, the PSU’s have no dividend or voting rights during the Performance Period. The grant date fair value of the portion of the PSU’s subject to the Performance Condition and the Market Condition component was $31.93 and $33.57 , respectively, for the 2018 PSU’s, $23.34 and $19.69 , respectively, for the 2017 PSU’s, and $16.85 and $15.75 , respectively, for the 2016 PSU’s. In accordance with ASC 718, for the portion of the PSU’s subject to a Market Condition, stock-based compensation expense is derived using the Monte Carlo simulation methodology and is recognized ratably over the service period regardless of whether or not the attainment of the Market Condition is probable. Therefore, the Company recognized $0.1 million in stock-based compensation expense during 2018 related to the Market Condition portion of the 2018, 2017 and 2016 PSU awards. There was a total of $0.1 million of unrecognized stock-based compensation expense related to the Market Condition portion of the 2018 and 2017 PSU awards as of December 31, 2018 . At December 31, 2018 , the Market Condition for the 2016 PSU awards was met, and the company recorded $0.1 million of stock-based compensation expense. Based on these results and board approval, 12,024 PSU’s vested during the first quarter of 2019 with respect to the portion of the 2016 PSU’s subject to the Market Condition. For the portion of the PSU’s subject to a Performance Condition, we recognize stock-based compensation expense on a straight-line basis over the Performance Period based on the probable outcome of the related Performance Condition. Otherwise, stock-based compensation expense recognition is deferred until probability is attained and a cumulative stock-based compensation expense adjustment is recorded and recognized ratably over the remaining service period. The Company reassesses the probability of the satisfaction of the Performance Condition on a quarterly basis, and stock-based compensation expense is adjusted based on the portion of the requisite service period that has passed. As of December 31, 2018 , the Company had not recognized any stock-based compensation expense related to the Performance Condition portion of the 2018 PSU awards. If the Company achieves the minimum performance levels for the Performance Condition to be met for the 2018 awards, the Company would record unrecognized stock-based compensation expense of $0.6 million as of December 31, 2018 , for which $0.2 million would be immediately recognized as if attainment been probable at December 31, 2018 . The Company recognized $0.4 million of stock-based compensation expense related to the Performance Condition portion of the 2017 PSU awards during 2018 based on the probability of attaining the Performance Condition. The Company has $0.2 million of unrecognized stock-based compensation expense related to the Performance Condition portion of the 2017 PSU awards at December 31, 2018 . The Company recognized $1.0 million of stock-based compensation expense related to the Performance Condition portion of the 2016 PSU awards as of December 31, 2018 based on the achievement of 106% of the target performance level. Based on these results and board approval, 80,023 PSU’s vested during the first quarter of 2019 with respect to the portion of the 2016 PSU awards subject to the Performance Condition. Deferred Compensation Plans The purpose of the Company’s Amended and Restated Executives’ Deferred Compensation Plan (the “Executive Plan”), a non-qualified deferred compensation plan, is to provide an opportunity for certain eligible employees of the Company to defer a portion of their compensation and to invest in the Company’s common shares. The purpose of the Company’s Amended and Restated Director Deferred Compensation Plan (the “Director Plan”) is to provide its directors with an opportunity to defer their director compensation and to invest in the Company’s common shares. Compensation expense deferred into the Executive Plan and the Director Plan (together the “Plans”) totaled $0.2 million , $0.4 million and $0.1 million for the years ended December 31, 2018, 2017 and 2016 , respectively. The portion of cash compensation deferred by employees and directors under the Plans is invested in fully-vested equity units in the Plans. One equity unit is the equivalent of one common share. Equity units and the related dividends (if any) will be converted and distributed to the employee or director in the form of common shares at the earlier of his or her elected distribution date or termination of service as an employee or director of the Company. Distributions from the Plans totaled $0.2 million during each of the years ended December 31, 2018 , 2017 and 2016. As of December 31, 2018 , there were a total of 48,781 equity units with a value of $1.1 million outstanding under the Plans. The aggregate fair market value of these units at December 31, 2018 , based on the closing price of the underlying common shares, was approximately $1.3 million , and the associated deferred tax benefit the Company would recognize if the outstanding units were distributed was $1.5 million as of December 31, 2018 . Common shares are issued from treasury shares upon distribution of equity units from the Plans. Profit Sharing and Retirement Plan The Company has a profit-sharing and retirement plan that covers substantially all Company employees and permits participants to make contributions to the plan on a pre-tax basis in accordance with the provisions of Section 401(k) of the Internal Revenue Code of 1986, as amended. Company contributions to the plan are also made at the discretion of the Company’s board of directors based on the Company’s profitability and resulted in a $2.3 million , $1.8 million and $1.4 million expense for the years ended December 31, 2018, 2017 and 2016 , respectively.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2018
Fair Value Measurements [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Measurements There are three measurement input levels for determining fair value: Level 1, Level 2, and Level 3. Fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. Assets Measured on a Recurring Basis To meet financing needs of our home-buying customers, M/I Financial is party to interest rate lock commitments (“IRLCs”), which are extended to customers who have applied for a mortgage loan and meet certain defined credit and underwriting criteria. These IRLCs are considered derivative financial instruments. M/I Financial manages interest rate risk related to its IRLCs and mortgage loans held for sale through the use of forward sales of mortgage-backed securities (“FMBSs”), the use of whole loan delivery commitments, and the occasional purchase of options on FMBSs in accordance with Company policy. These FMBSs, options on FMBSs, and IRLCs covered by FMBSs are considered non-designated derivatives. These amounts are either recorded in Other Assets or Other Liabilities on the Consolidated Balance Sheets (depending on the respective balance for that year ended December 31). The Company measures both mortgage loans held for sale and IRLCs at fair value. Fair value measurement results in a better presentation of the changes in fair values of the loans and the derivative instruments used to economically hedge them. In the normal course of business, our financial services segment enters into contractual commitments to extend credit to buyers of single-family homes with fixed expiration dates. The commitments become effective when the borrowers “lock-in” a specified interest rate within established time frames. Market risk arises if interest rates move adversely between the time of the “lock-in” of rates by the borrower and the sale date of the loan to an investor. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, the Company enters into optional or mandatory delivery forward sale contracts to sell whole loans and mortgage-backed securities to broker/dealers. The forward sale contracts lock in an interest rate and price for the sale of loans similar to the specific rate lock commitments. The Company does not engage in speculative or trading derivative activities. Both the rate lock commitments to borrowers and the forward sale contracts to broker/dealers or investors are undesignated derivatives, and accordingly, are marked to fair value through earnings. Changes in fair value measurements are included in earnings in the accompanying Consolidated Statements of Income. The fair value of mortgage loans held for sale is estimated based primarily on published prices for mortgage-backed securities with similar characteristics. To calculate the effects of interest rate movements, the Company utilizes applicable published mortgage-backed security prices, and multiplies the price movement between the rate lock date and the balance sheet date by the notional loan commitment amount. The Company sells loans on a servicing released or servicing retained basis, and receives servicing compensation. Thus, the value of the servicing rights included in the fair value measurement is based upon contractual terms with investors and depends on the loan type. The Company applies a fallout rate to IRLCs when measuring the fair value of rate lock commitments. Fallout is defined as locked loan commitments for which the Company does not close a mortgage loan and is based on management’s judgment and company experience. The fair value of the Company’s forward sales contracts to broker/dealers solely considers the market price movement of the same type of security between the trade date and the balance sheet date. The market price changes are multiplied by the notional amount of the forward sales contracts to measure the fair value. Interest Rate Lock Commitments. IRLCs are extended to certain home-buying customers who have applied for a mortgage loan and meet certain defined credit and underwriting criteria. Typically, the IRLCs will have a term of less than six months; however, in certain markets, the term could extend to nine months. Some IRLCs are committed to a specific third party investor through the use of whole loan delivery commitments matching the exact terms of the IRLC loan. Uncommitted IRLCs are considered derivative instruments and are fair value adjusted, with the resulting gain or loss recorded in current earnings. Forward Sales of Mortgage-Backed Securities. FMBSs are used to protect uncommitted IRLC loans against the risk of changes in interest rates between the lock date and the funding date. FMBSs related to uncommitted IRLCs are classified and accounted for as non-designated derivative instruments and are recorded at fair value, with gains and losses recorded in current earnings. Mortgage Loans Held for Sale. Mortgage loans held for sale consist primarily of single-family residential loans collateralized by the underlying property. During the period between when a loan is closed and when it is sold to an investor, the interest rate risk is covered through the use of a whole loan contract or by FMBSs.

Our determination of fair value is based on projections and estimates, which are Level 3 measurement inputs. For further explanation of the Company’s policy regarding our assessment of recoverability for assets measured on a non-recurring basis, please see Note 1 to our Consolidated Financial Statements. The table below shows the level and measurement of assets measured on a non-recurring basis for the years ended December 31, 2018, 2017 and 2016: Year Ended December 31, Description (in thousands) Hierarchy 2018 2017 (2) 2016 (2) Adjusted basis of inventory (1) Level 3 $ 14,515 $ 3,823 $ 12,921 Total losses 5,809 7,681 3,992 Initial basis of inventory (3) $ 20,324 $ 11,504 $ 16,913 (1) The fair values in the table above represent only assets whose carrying values were adjusted in the respective period. (2) The carrying values for these assets may have subsequently increased or decreased from the fair value reported due to activities that have occurred since the measurement date. (3) This amount is inclusive of our investments in joint venture arrangements. There were no losses on our investments in joint venture arrangements for 2018 , 2017 and 2016 . Financial Instruments Counterparty Credit Risk. To reduce the risk associated with losses that would be recognized if counterparties failed to perform as contracted, the Company limits the entities with whom management can enter into commitments. This risk of accounting loss is the difference between the market rate at the time of non-performance by the counterparty and the rate to which the Company committed. The following table presents the carrying amounts and fair values of the Company’s financial instruments at December 31, 2018 and 2017 . The objective of the fair value measurement is to estimate the price at which an orderly transaction to sell the asset or transfer the liability would take place between market participants at the measurement date under current market conditions.

The following methods and assumptions were used by the Company in estimating its fair value disclosures of financial instruments at December 31, 2018 and 2017 : Cash, Cash Equivalents and Restricted Cash. The carrying amounts of these items approximate fair value because they are short-term by nature. Mortgage Loans Held for Sale, Forward Sales of Mortgage-Backed Securities, Commitments to Extend Real Estate Loans, Whole loan Contracts for Committed IRLCs and Mortgage Loans Held for Sale, Convertible Senior Subordinated Notes due 2018, Senior Notes due 2021 and Senior Notes due 2025. The fair value of these financial instruments was determined based upon market quotes at December 31, 2018 and 2017 . The market quotes used were quoted prices for similar assets or liabilities along with inputs taken from observable market data by correlation. The inputs were adjusted to account for the condition of the asset or liability. Split Dollar Life Insurance Policy and Notes Receivable. The estimated fair value was determined by calculating the present value of the amounts based on the estimated timing of receipts using discount rates that incorporate management’s estimate of risk associated with the corresponding note receivable. Notes Payable - Homebuilding Operations. The interest rate available to the Company during 2018 under the Company’s $500 million unsecured revolving credit facility, dated July 18, 2013, as amended (the “Credit Facility”), fluctuated daily with the one-month LIBOR rate plus a margin of 250 basis points, and thus the carrying value is a reasonable estimate of fair value. Please see Note 11 to our Consolidated Financial Statements for additional information regarding the Credit Facility. Notes Payable - Financial Services Operations. M/I Financial is a party to two credit agreements: (1) a $125 million secured mortgage warehousing agreement (which increases to $160 million during certain periods), dated June 24, 2016 , as amended (the “MIF Mortgage Warehousing Agreement”), and (2) a $50 million mortgage repurchase agreement (which increases to $65 million during certain periods), dated October 30, 2017 , as amended (the “MIF Mortgage Repurchase Facility”). For each of these credit facilities, the interest rate is based on a variable rate index, and thus their carrying value is a reasonable estimate of fair value. The interest rate available to M/I Financial during 2018 fluctuated with LIBOR. Please see Note 11 to our Consolidated Financial Statements for additional information regarding the MIF Mortgage Warehousing Agreement and the MIF Mortgage Repurchase Facility. Notes Payable - Other. The estimated fair value was determined by calculating the present value of the future cash flows using the Company’s current incremental borrowing rate. Letters of Credit. Letters of credit of $52.7 million and $49.7 million represent potential commitments at December 31, 2018 and 2017 , respectively. The letters of credit generally expire within one or two years. The estimated fair value of letters of credit was determined using fees currently charged for similar agreements.

Investment in Joint Venture Arrangements [Abstract]
Equity Method Investments Disclosure [Text Block]	Investment in Joint Venture Arrangements The Company has periodically partnered with other land developers or homebuilders to share in the cost of land investment and development of a property through joint ownership and development agreements, joint ventures, and other similar arrangements. For such joint venture arrangements where a special purpose entity is established to own the property, we have determined that we do not have substantive control over any of these entities; therefore, the Company’s joint venture arrangements are recorded using the equity method of accounting. We believe the Company’s maximum exposure related to its investment in these joint venture arrangements as of December 31, 2018 is the total amount invested of $35.9 million (reported as Investment in Joint Venture Arrangements on our Consolidated Balance Sheets), which amount may increase as a result of further investments that are expected as development of the properties progresses. The Company evaluates its investment in joint venture arrangements for potential impairment on a quarterly basis. If the fair value of the investment (please see Notes 1 and 3 to our Consolidated Financial Statements) is less than the investment’s carrying value, and the Company determines the decline in value was other than temporary, the Company writes down the investment to fair value. Summarized condensed combined financial information for the joint venture arrangements that are included in the homebuilding segments, and for which a special purpose entity was established, as of December 31, 2018 and 2017 and for the years ended December 31, 2018, 2017 and 2016 is as follows: Summarized Condensed Combined Balance Sheets: December 31, (In thousands) 2018 2017 Assets: Single-family lots, land and land development costs (a) (b) $ 11,182 $ 13,289 Other assets 938 5,143 Total assets $ 12,120 $ 18,432 Liabilities and partners’ equity: Liabilities: Notes payable $ 2,318 $ 261 Other liabilities 599 1,544 Total liabilities 2,917 1,805 Partners’ equity: Company’s equity (a) (b) $ 2,525 $ 8,328 Other equity 6,678 8,299 Total partners’ equity $ 9,203 $ 16,627 Total liabilities and partners’ equity $ 12,120 $ 18,432 (a) For the years ended December 31, 2018 and 2017 , impairment expenses and other miscellaneous adjustments totaling less than ($0.1 million) and $1.7 million , respectively, were excluded from the table above. (b) For the years ended December 31, 2018 and 2017 , the table above excludes the Company’s investment in joint development arrangements for which a special purpose entity was not established, totaling $33.3 million and $13.9 million , respectively. Summarized Condensed Combined Statements of Operations: Year Ended December 31, (In thousands) 2018 2017 2016 Revenue $ 4,632 $ 10,286 $ 5,995 Costs and expenses 2,748 6,817 5,849 Income $ 1,884 $ 3,469 $ 146 (a) For the years ended December 31, 2018 and 2017 , the table above excludes the Company’s investment in joint development arrangements for which a special purpose entity was not established.

Guarantees [Abstract]
Guarantees [Text Block]	Guarantees and Indemnifications In the ordinary course of business, M/I Financial enters into agreements that guarantee certain purchasers of its mortgage loans that M/I Financial will repurchase a loan if certain conditions occur, primarily if the mortgagor does not meet the terms of the loan within the first six months after the sale of the loan. Loans totaling approximately $63.6 million and $46.8 million were covered under these guarantees as of December 31, 2018 and 2017 , respectively. The increase in loans covered by these guarantees from December 31, 2017 is a result of a change in the mix of investors and their related purchase terms. A portion of the revenue paid to M/I Financial for providing the guarantees on these loans was deferred at December 31, 2018 , and will be recognized in income as M/I Financial is released from its obligation under the guarantees. The risk associated with the guarantees above is offset by the value of the underlying assets. M/I Financial has received inquiries concerning underwriting matters from purchasers of its loans regarding certain loans totaling approximately $0.6 million and $1.2 million at December 31, 2018 and 2017 , respectively. M/I Financial has also guaranteed the collectability of certain loans to third party insurers (U.S. Department of Housing and Urban Development and U.S. Veterans Administration) of those loans for periods ranging from five to thirty years. As of December 31, 2018 and 2017 , the total of all loans indemnified to third party insurers relating to the above agreements was $1.0 million and $1.3 million , respectively. The maximum potential amount of future payments is equal to the outstanding loan value less the value of the underlying asset plus administrative costs incurred related to foreclosure on the loans, should this event occur. The Company recorded a liability relating to the guarantees described above totaling $0.6 million and $0.8 million at December 31, 2018 and 2017 , respectively, which is management’s best estimate of the Company’s liability with respect to such guarantees.

Commitments and Contingencies [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies Warranty Our warranty reserves are included in Other Liabilities in the Company’s Consolidated Balance Sheets, as further explained in Note 1 to our Consolidated Financial Statements. A summary of warranty activity for the years ended December 31, 2018, 2017 and 2016 is as follows: Year Ended December 31, (In thousands) 2018 2017 2016 Warranty reserves, beginning of period $ 26,133 $ 27,732 $ 14,282 Warranty expense on homes delivered during the period 13,456 11,677 10,452 Changes in estimates for pre-existing warranties 4,746 2,614 3,304 Charges related to stucco-related claims (a) — 8,500 19,409 Settlements made during the period (17,876 ) (24,390 ) (19,715 ) Warranty reserves, end of period $ 26,459 $ 26,133 $ 27,732 (a) These amounts represent charges for stucco-related repair costs net of recoveries from insurers during the period. We have received claims related to stucco installation from homeowners in certain of our communities in our Tampa and Orlando, Florida markets and have been named as a defendant in legal proceedings initiated by certain of such homeowners. These claims primarily relate to homes built prior to 2014 which have second story elevations with frame construction. During 2015, 2016 and 2017, we recorded an aggregate total of $28.4 million of warranty charges for stucco-related repair costs for (1) homes in our Florida communities that we had identified as needing repair but had not yet completed the repair and (2) estimated repair costs for homes in our Florida communities that we had not yet identified as needing repair but that may require repair in the future. During the fourth quarter of 2018, as a result of our on-going review of stucco-related data described below, we incurred an additional stucco-related charge of $1.0 million . During the fourth quarter of 2018, we also received $1.0 million of recoveries from insurers for past stucco-related claims, resulting in a net charge of zero. Stucco-related insurance recoveries are recorded in the period the reimbursement is received. The remaining reserve for both known repair costs and an estimate of future costs of stucco-related repairs at December 31, 2018 included within our warranty reserve was $6.3 million . We believe that this amount is sufficient to cover both known and estimated future repair costs as of December 31, 2018 . Our remaining stucco-related reserve is gross of any insurance recoveries. Our review of the stucco-related issues in our Florida communities is ongoing. Our estimate of future costs of stucco-related repairs is based on our judgment, various assumptions and internal data. Due to the degree of judgment and the potential for variability in our underlying assumptions and data, as we obtain additional information, we may revise our estimate, including to reflect additional estimated future stucco-related repairs costs, which revision could be material. We continue to investigate the extent to which we may be able to further recover a portion of our stucco repair and claims handling costs from other sources, including our direct insurers, the subcontractors involved with the construction of the homes and their insurers. As of December 31, 2018 , we are unable to estimate any additional amount that we believe is probable of recovery from these sources and, as noted above, we have not recorded a receivable for recoveries nor included an estimated amount of recoveries in determining our stucco-related warranty reserve. Performance Bonds and Letters of Credit At December 31, 2018 , the Company had outstanding approximately $215.0 million of completion bonds and standby letters of credit, some of which were issued to various local governmental entities that expire at various times through September 2026 . Included in this total are: (1) $155.4 million of performance and maintenance bonds and $42.4 million of performance letters of credit that serve as completion bonds for land development work in progress; (2) $10.3 million of financial letters of credit, of which $9.9 million represent deposits on land and lot purchase agreements; and (3) $6.9 million of financial bonds. Land Option Contracts and Other Similar Contracts At December 31, 2018 , the Company also had options and contingent purchase agreements to acquire land and developed lots with an aggregate purchase price of approximately $636.4 million . Purchase of properties under these agreements is contingent upon satisfaction of certain requirements by the Company and the sellers. Legal Matters In addition to the legal proceedings related to stucco, the Company and certain of its subsidiaries have been named as defendants in certain other legal proceedings which are incidental to our business. While management currently believes that the ultimate resolution of these other legal proceedings, individually and in the aggregate, will not have a material effect on the Company’s financial position, results of operations and cash flows, such legal proceedings are subject to inherent uncertainties. The Company has recorded a liability to provide for the anticipated costs, including legal defense costs, associated with the resolution of these other legal proceedings. However, the possibility exists that the costs to resolve these legal proceedings could differ from the recorded estimates and, therefore, have a material effect on the Company’s net income for the periods in which they are resolved. At both December 31, 2018 and 2017 , we had $0.4 million reserved for legal expenses.

Community Development District Infrastructure and Realted Obligations [Abstract]
Community Development District Bonds [Text Block]	Community Development District Infrastructure and Related Obligations A Community Development District and/or Community Development Authority (“CDD”) is a unit of local government created under various state and/or local statutes to encourage planned community development and to allow for the construction and maintenance of long-term infrastructure through alternative financing sources, including the tax-exempt markets. A CDD is generally created through the approval of the local city or county in which the CDD is located and is controlled by a Board of Supervisors representing the landowners within the CDD. CDDs may utilize bond financing to fund construction or acquisition of certain on-site and off-site infrastructure improvements near or within these communities. CDDs are also granted the power to levy special assessments to impose ad valorem taxes, rates, fees and other charges for the use of the CDD project. An allocated share of the principal and interest on the bonds issued by the CDD is assigned to and constitutes a lien on each parcel within the community evidenced by an assessment (the “Assessment”). The owner of each such parcel is responsible for the payment of the Assessment on that parcel. If the owner of the parcel fails to pay the Assessment, the CDD may foreclose on the lien pursuant to powers conferred to the CDD under applicable state laws and/or foreclosure procedures. In connection with the development of certain of the Company’s communities, CDDs have been established and bonds have been issued to finance a portion of the related infrastructure.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	Debt Notes Payable - Homebuilding The Credit Facility provides an aggregate commitment amount of $500 million , including a $125 million sub-facility for letters of credit. The Credit Facility expires on July 18, 2021 . Interest on amounts borrowed under the Credit Facility is payable at a rate which is adjusted daily and is equal to the sum of the one-month LIBOR rate plus a margin of 250 basis points. The margin is subject to adjustment in subsequent quarterly periods based on the Company’s leverage ratio. The available amount under the Credit Facility is computed in accordance with a borrowing base, which is calculated by applying various advance rates for different categories of inventory, and totaled $587.1 million of availability for additional senior debt at December 31, 2018 . As a result, the full $500 million commitment amount of the Credit Facility was available, less any borrowings and letters of credit outstanding. At December 31, 2018 , there were $117.4 million borrowings outstanding and $52.7 million of letters of credit outstanding, leaving net remaining borrowing availability of $329.9 million . The Company’s obligations under the Credit Facility are guaranteed by all of the Company’s subsidiaries, with the exception of subsidiaries that are primarily engaged in the business of mortgage financing, title insurance or similar financial businesses relating to the homebuilding and home sales business, certain subsidiaries that are not 100%-owned by the Company or another subsidiary, and other subsidiaries designated by the Company as Unrestricted Subsidiaries (as defined in Note 16 to our Consolidated Financial Statements), subject to limitations on the aggregate amount invested in such Unrestricted Subsidiaries in accordance with the terms of the Credit Facility and the indentures for the Company’s $250.0 million aggregate principal amount of 5.625% Senior Notes due 2025 (the “2025 Senior Notes”) and the Company’s $300.0 million aggregate principal amount of 6.75% Senior Notes due 2021 (the “2021 Senior Notes”). The guarantors for the Credit Facility (the “Guarantor Subsidiaries”) are the same subsidiaries that guarantee the 2025 Senior Notes and the 2021 Senior Notes. The Company’s obligations under the Credit Facility are general, unsecured senior obligations of the Company and the Guarantor Subsidiaries and rank equally in right of payment with all our and the Guarantor Subsidiaries’ existing and future unsecured senior indebtedness. Our obligations under the Credit Facility are effectively subordinated to our and the Guarantor Subsidiaries’ existing and future secured indebtedness with respect to any assets comprising security or collateral for such indebtedness. The Credit Facility contains various representations, warranties and covenants which require, among other things, that the Company maintain (1) a minimum level of Consolidated Tangible Net Worth of $531.7 million (subject to increase over time based on earnings and proceeds from equity offerings), (2) a leverage ratio not in excess of 60% , and (3) either a minimum Interest Coverage Ratio of 1.5 to 1.0 or a minimum amount of available liquidity. In addition, the Credit Facility contains covenants that limit the Company's number of unsold housing units and model homes, as well as the amount of Investments in Unrestricted Subsidiaries and Joint Ventures. At December 31, 2018 , the Company was in compliance with all financial covenants of the Credit Facility. During 2018 , the Company was a party to a secured credit agreement (the “Letter of Credit Facility”) which allowed for the issuance of letters of credit up to a total of $1.0 million secured by cash collateral. The Company elected not to extend the maturity of its Letter of Credit Facility, which expired on September 30, 2018. There were no letters of credit remaining outstanding at the time of maturity. At December 31, 2017, there was $0.6 million of outstanding letters of credit in aggregate under the Letter of Credit Facility, which were collateralized with $0.6 million of the Company’s cash.

The 2025 Senior Notes bear interest at a rate of 5.625% per year, payable semiannually in arrears on February 1 and August 1 of each year, and mature on August 1, 2025. We may redeem all or any portion of the 2025 Senior Notes on or after August 1, 2020 at a stated redemption price, together with accrued and unpaid interest thereon. The redemption price will initially be 104.219% of the principal amount outstanding, but will decline to 102.813% of the principal amount outstanding if redeemed during the 12-month period beginning on August 1, 2021, will further decline to 101.406% of the principal amount outstanding if redeemed during the 12-month period beginning on August 1, 2022 and will further decline to 100.000% of the principal amount outstanding if redeemed on or after August 1, 2023, but prior to maturity.

This rate declines to 100.000% of the principal amount outstanding if redeemed on or after January 15, 2020, but prior to maturity. The 2025 Senior Notes and the 2021 Senior Notes contain certain covenants, as more fully described and defined in the indenture governing the 2025 Senior Notes and the indenture governing the 2021 Senior Notes, which limit the ability of the Company and the restricted subsidiaries to, among other things: incur additional indebtedness; make certain payments, including dividends, or repurchase any shares, in an aggregate amount exceeding our “restricted payments basket”; make certain investments; and create or incur certain liens, consolidate or merge with or into other companies, or liquidate or sell or transfer all or substantially all of our assets. These covenants are subject to a number of exceptions and qualifications as described in the indenture governing the 2025 Senior Notes and the indenture governing the 2021 Senior Notes. As of December 31, 2018 , the Company was in compliance with all terms, conditions, and covenants under the indentures. The 2025 Senior Notes and the 2021 Senior Notes are fully and unconditionally guaranteed jointly and severally on a senior unsecured basis by the Guarantor Subsidiaries.

Acquisition and Goodwill [Abstract]
Mergers, Acquisitions and Dispositions Disclosures [Text Block]	Acquisition and Goodwill Acquisition In March 2018, we entered the Detroit, Michigan market through the acquisition of the homebuilding assets and operations of Pinnacle Homes for a purchase price of $101.0 million . The results of Pinnacle Homes’ operations have been included in our financial statements since March 1, 2018, the effective date of the acquisition. As a result of the transaction, we recorded $16.4 million of goodwill (all of which is tax deductible) which relates to expected synergies from establishing a market presence in Detroit, the experience and knowledge of the acquired workforce and the capital-efficient operating structure of the business acquired. The remaining basis of $84.6 million is almost entirely comprised of the fair value of the acquired inventory with an insignificant amount attributable to other assets and liabilities. 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. In connection with the Company’s acquisition of the homebuilding assets and operations of Pinnacle Homes in Detroit, Michigan described above, the Company recorded goodwill of $16.4 million as of December 31, 2018 , which is included as Goodwill in our Consolidated Balance Sheets. This amount was based on the estimated fair values of the acquired assets and liabilities at the date of the acquisition in accordance with ASC 350. In accordance with ASC 350, the Company analyzes goodwill for impairment on an annual basis (or more often if indicators of impairment exist). The Company performs a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment indicates that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, then a quantitative assessment is performed to determine the reporting unit’s fair value. If the reporting unit’s carrying value exceeds its fair value, then an impairment loss is recognized for the amount of the excess of the carrying amount over the reporting unit’s fair value. The Company performed its annual goodwill impairment analysis during the fourth quarter of 2018, and as no indicators for impairment existed at December 31, 2018 , no impairment was recorded.

Income Taxes

Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The Company records income taxes under the asset and liability method, whereby deferred tax assets and liabilities are recognized based on future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and attributable to operating loss and tax credit carryforwards, if any. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which the temporary differences are expected to be recovered or paid. During the fourth quarter of 2017, comprehensive federal tax legislation was enacted in the form of the 2017 Tax Act. The 2017 Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, reducing the corporate income tax rate from 35% to 21%, eliminating the corporate alternative minimum tax, repealing the domestic production activity deduction, and limiting the deductibility of certain executive compensation. The SEC staff issued SAB 118 in December 2017, which provides guidance on accounting for the tax effects of the 2017 Tax Act. SAB 118 provides that the measurement period for the tax effects of the 2017 Tax Act should not extend more than one year from the date the 2017 Tax Act was enacted. To the extent that a company's accounting for certain income tax effects of the 2017 Tax Act is incomplete but the company is able to determine a reasonable estimate, the company must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the 2017 Tax Act was enacted. As a result of the reduction in the corporate income tax rate, the Company revalued its deferred tax assets at December 31, 2017 and recognized a non-cash provisional tax expense of $6.5 million for the year ended December 31, 2017. We completed our accounting for the income tax effects of the 2017 Tax Act in 2018, and no material adjustments were required to the provisional amounts initially recorded. In accordance with ASC 740 , we evaluate our deferred tax assets, including the benefit from NOLs and tax credit carryforwards, if any, to determine if a valuation allowance is required. Companies must assess, using significant judgments, whether a valuation allowance should be established based on the consideration of all available evidence using a “more likely than not” standard with significant weight being given to evidence that can be objectively verified. 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. Based upon a review of all available evidence, we believe our deferred tax assets were fully realizable in all periods presented. At December 31, 2018 , the Company’s total deferred tax assets were $20.2 million which is offset by $6.7 million of total deferred tax liabilities for a $13.5 million net deferred tax asset which is reported on the Company’s Consolidated Balance Sheets. The tax effects of the significant temporary differences that comprise the deferred tax assets and liabilities are as follows: December 31, (In thousands) 2018 2017 Deferred tax assets: Warranty, insurance and other accruals $ 8,218 $ 8,078 Equity-based compensation 4,096 3,250 Inventory 4,441 4,720 State taxes 185 160 Net operating loss carryforward 3,240 6,193 Deferred charges — 506 Total deferred tax assets $ 20,180 $ 22,907 Deferred tax liabilities: Federal effect of state deferred taxes $ 1,079 $ 1,777 Depreciation 4,801 2,382 Prepaid expenses 285 310 Other 533 — Total deferred tax liabilities $ 6,698 $ 4,469 Net deferred tax asset $ 13,482 $ 18,438 The provision from income taxes consists of the following: Year Ended December 31, (In thousands) 2018 2017 2016 Current: Federal $ 24,408 $ 33,392 $ 1,745 State 4,261 2,414 2,120 $ 28,669 $ 35,806 $ 3,865 Year Ended December 31, (In thousands) 2018 2017 2016 Deferred: Federal $ 2,333 $ 11,916 $ 28,335 State 2,624 521 2,976 $ 4,957 $ 12,437 $ 31,311 Total $ 33,626 $ 48,243 $ 35,176 For 2018, 2017 and 2016 , the Company’s effective tax rate was 23.80% , 40.09% , and 38.32% , respectively. The decrease in the effective tax rate was primarily attributable to the 2017 Tax Act which included the reduction of the corporate income tax rate from 35% to 21%, partially offset by the repeal of the domestic production activity deduction and other non-deductible costs. Also as a result of the 2017 Tax Act, the Company revalued its deferred tax assets and recognized a $6.5 million non-cash tax expense in 2017. Reconciliation of the differences between income taxes computed at the federal statutory tax rate and consolidated benefit from income taxes are as follows: Year Ended December 31, (In thousands) 2018 2017 2016 Federal taxes at statutory rate $ 29,671 $ 42,113 $ 32,125 State and local taxes – net of federal tax benefit 5,636 3,420 3,652 Change in state NOL deferred asset – net of federal tax benefit — — 729 Deferred tax asset re-measurement as a result of 2017 Tax Act — 6,520 — Equity Compensation (254 ) (1,368 ) — Manufacturing deduction — (3,262 ) (1,298 ) Federal tax credits (2,817 ) — — Other 1,390 820 (32 ) Total $ 33,626 $ 48,243 $ 35,176 The Company files income tax returns in the U.S. federal jurisdiction, and various states. The Company is no longer subject to U.S. federal, state or local examinations by tax authorities for years before 2015. The Company is audited from time to time, and if any adjustments are made, they would be either immaterial or reserved. The Company recognizes interest and penalties accrued related to unrecognized tax benefits in tax expense. At December 31, 2018 , 2017 and 2016 , we had no unrecognized tax benefits due to the lapse of the statute of limitations and completion of audits in prior years. We believe that our current income tax filing positions and deductions will be sustained on audit and do not anticipate any adjustments that will result in a material change. During 2016, the Company fully utilized its federal NOL carryforwards and federal credit carryforwards. The Company had $2.6 million of state NOL carryforwards, net of the federal benefit, at December 31, 2018 . Our state NOLs may be carried forward from one to 15 years, depending on the tax jurisdiction, with $0.9 million expiring between 2022 and 2027 and $1.7 million expiring between 2028 and 2032, absent sufficient state taxable income.

(b) Gross margin and net income to common shareholders includes an $8.5 million pre-tax charge for stucco-related repair costs in certain of our Florida communities (as more fully discussed in Note 8 to our Consolidated Financial Statements) taken during the second quarter of 2017, and $7.7 million of impairment charges taken during the fourth quarter of 2017. (c) Due to rounding, the sum of quarterly results may not equal the total for the year. Additionally, quarterly and year-to-date computations of per share amounts are made independently. We typically experience significant seasonality and quarter-to-quarter variability in our operating results. In general, homes delivered increase substantially in the second half of the year compared to the first half of the year as we sell more homes during the first and second quarters which results in more homes being delivered in the third and fourth quarters.

Share Repurchase Program [Abstract]
Treasury Stock [Text Block]	Share Repurchase Program On August 14, 2018, the Company announced that its Board of Directors authorized a share repurchase program (the “2018 Share Repurchase Program”) pursuant to which the Company may purchase up to $50 million of its outstanding common shares through open market transactions, privately negotiated transactions or otherwise in accordance with all applicable laws. During the year ended December 31, 2018 , the Company repurchased 1.1 million outstanding common shares at an aggregate purchase price of $25.7 million under the 2018 Share Repurchase Program and $24.3 million remained available for repurchases under the 2018 Share Repurchase Program. The timing, amount and other terms and conditions of any additional repurchases under the 2018 Share Repurchase Program will be determined by the Company’s management at its discretion based on a variety of factors, including the market price of the Company’s common shares, corporate considerations, general market and economic conditions and legal requirements. The 2018 Share Repurchase Program does not have an expiration date and the Board may modify, discontinue or suspend it at any time.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Business, Policy [Policy Text Block]	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 and Sarasota, Florida; Austin, Dallas/Fort Worth, Houston and San Antonio, Texas; Charlotte and Raleigh, North Carolina; and the Virginia and Maryland suburbs of Washington, D.C. 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 three geographic regions in the United States. Within these regions, our operations have similar economic characteristics; therefore, they have been aggregated into three reportable homebuilding segments: Midwest homebuilding, Southern homebuilding and Mid-Atlantic 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% and majority-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, Policy [Policy Text Block]	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 disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	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, 2018 and 2017 , respectively. Restricted cash consists of amounts held in restricted accounts as collateral for letters of credit as well as cash held in escrow. Cash, Cash Equivalents and Restricted Cash includes restricted cash balances of $0.7 million and $1.0 million at December 31, 2018 and 2017 , respectively.
Loans and Leases Receivable, Mortgage Banking Activities, Policy [Policy Text Block]	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, Policy [Policy Text Block]	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 land 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, 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. As of December 31, 2018 , our projections generally assume a gradual improvement in market conditions over time. 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, 2018 and December 31, 2017 , 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. 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.
Interest Capitalization, Policy [Policy Text Block]	Capitalized Interest. The Company capitalizes interest during land development and home construction. Capitalized interest is charged to cost of sales as the related inventory is delivered to a third party. The summary of capitalized interest for the years ended December 31, 2018, 2017 and 2016 is as follows: Year Ended December 31, (In thousands) 2018 2017 2016 Capitalized interest, beginning of period $ 17,169 $ 16,012 $ 16,740 Interest capitalized to inventory 29,053 21,484 17,685 Capitalized interest charged to cost of sales (25,457 ) (20,327 ) (18,413 ) Capitalized interest, end of year $ 20,765 $ 17,169 $ 16,012 Interest incurred $ 49,537 $ 40,358 $ 35,283
Equity Method Investments [Policy Text Block]	Investment in Joint Venture Arrangements. In order to minimize our investment and risk of land exposure in a single location, we have periodically partnered with other land developers or homebuilders to share in the land investment and development of a property through joint ownership and development agreements, joint ventures, and other similar arrangements. During 2018 , we increased our total investment in such joint venture arrangements by $15.4 million from $20.5 million at December 31, 2017 to $35.9 million at December 31, 2018 , which was driven primarily by our cash contributions to our joint venture arrangements during 2018 of $31.9 million , offset, in part, by our lot distributions from our joint venture arrangements during 2018 of $16.2 million . We believe that the Company’s maximum exposure related to its investment in these joint venture arrangements as of December 31, 2018 is the amount invested of $35.9 million , which is reported as Investment in Joint Venture Arrangements on our Consolidated Balance Sheets, although we expect to invest further amounts in these joint venture arrangements as development of the properties progresses. Further details relating to our joint venture arrangements are included in Note 6 to our Consolidated Financial Statements. We use the equity method of accounting for investments in joint venture arrangements over which we exercise significant influence but do not have a controlling interest. Under the equity method, our share of the joint venture arrangements’ earnings or loss, if any, is included in our Consolidated Statements of Income. The Company assesses its investments in joint venture arrangements for recoverability on a quarterly basis in accordance with ASC 323, Investments - Equity Method and Joint Ventures (“ASC 323”) as described below. If the fair value of the investment is less than the investment’s carrying value, and the Company has determined that the decline in value is other than temporary, the Company would write down the value of the investment to its estimated fair value. The determination of whether an investment’s fair value is less than the carrying value requires management to make certain assumptions regarding the amount and timing of future contributions to the joint venture arrangements, the timing of distribution of lots to the Company from the joint venture arrangements, the projected fair value of the lots at the time of distribution to the Company, and the estimated proceeds from, and timing of, the sale of land or lots to third parties. In determining the fair value of investments in joint venture arrangements, the Company evaluates the projected cash flows associated with each joint venture arrangement. As of both December 31, 2018 and December 31, 2017 , the Company used a discount rate of 16% in determining the fair value of investments in joint venture arrangements. In addition to the assumptions management must make to determine if the investment’s fair value is less than the carrying value, management must also use judgment in determining whether the impairment is other than temporary. The factors management considers are: (1) the length of time and the extent to which the market value has been less than cost; (2) the financial condition and near-term prospects of the joint venture arrangement; and (3) the intent and ability of the Company to retain its investment in the joint venture arrangements for a period of time sufficient to allow for any anticipated recovery in market value. Due to uncertainties in the estimation process and the significant volatility in demand for new housing, actual results could differ significantly from such estimates. For joint venture arrangements where a special purpose entity is established to own the property, we generally enter into limited liability company or similar arrangements (“LLCs”) with the other partners. The Company’s ownership in these LLCs as of both December 31, 2018 and December 31, 2017 ranged from 25% to 97% . These entities typically engage in land development activities for the purpose of distributing or selling developed lots to the Company and its partners in the LLC.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	Variable Interest Entities. With respect to our investments in LLCs, we are required, under ASC 810-10, Consolidation (“ASC 810”), to evaluate whether or not such entities should be consolidated into our consolidated financial statements. We initially perform these evaluations when each new entity is created and upon any events that require reconsideration of the entity. In order to determine if we should consolidate an LLC, we determine (1) if the LLC is a variable interest entity (“VIE”) and (2) if we are the primary beneficiary of the entity. To determine whether we are the primary beneficiary of an entity, we consider whether we have the ability to control the activities of the VIE that most significantly impact its economic performance. This analysis considers, among other things, whether we have: the ability to determine the budget and scope of land development work, if any; the ability to control financing decisions for the VIE; the ability to acquire additional land into the VIE or dispose of land in the VIE not under contract with M/I Homes; and the ability to change or amend the existing option contract with the VIE. If we determine that we are not able to control such activities, we are not considered the primary beneficiary of the VIE. As of December 31, 2018 and December 31, 2017, we have determined that no LLC in which we have an interest met the requirements of a VIE.
Off-Balance Sheet Obligations [Policy Text Block]	Land Option Agreements. In the ordinary course of business, the Company enters into land option or purchase agreements for which we generally pay non-refundable deposits. Pursuant to these land option agreements, the Company provides a deposit to the seller as consideration for the right to purchase land at different times in the future, usually at predetermined prices. In accordance with ASC 810, we analyze our land option or purchase agreements to determine whether the corresponding land sellers are VIEs and, if so, whether we are the primary beneficiary, using an analysis similar to that described above. Although we do not have legal title to the optioned land, ASC 810 requires a company to consolidate a VIE if the company is determined to be the primary beneficiary. In cases where we are the primary beneficiary, even though we do not have title to such land, we are required to consolidate these purchase/option agreements and reflect such assets and liabilities as Consolidated Inventory not Owned in our Consolidated Balance Sheets. At both December 31, 2018 and 2017 , we have concluded that we were not the primary beneficiary of any VIEs from which we are purchasing land under option or purchase agreements. In addition, we evaluate our land option or purchase agreements to determine for each contract if (1) a portion or all of the purchase price is a specific performance requirement, or (2) the amount of deposits and prepaid acquisition and development costs exceed certain thresholds relative to the remaining purchase price of the lots. If either is the case, then the remaining purchase price of the lots (or the specific performance amount, if applicable) is recorded as an asset and liability in Consolidated Inventory Not Owned (as further described below) on our Consolidated Balance Sheets. Other than as described below in “Consolidated Inventory Not Owned,” the Company currently believes that its maximum exposure as of December 31, 2018 related to our land option agreements is equal to the amount of the Company’s outstanding deposits and prepaid acquisition costs, which totaled $55.0 million , including cash deposits of $33.7 million , prepaid acquisition costs of $7.9 million , letters of credit of $9.9 million and $3.5 million of other non-cash deposits.
Consolidated Inventory Not Owned [Policy Text Block]	Consolidated Inventory Not Owned and Related Obligation . At December 31, 2018 and December 31, 2017 , Consolidated Inventory Not Owned was $19.3 million and $21.5 million , respectively. At December 31, 2018 and 2017 , the corresponding liability of $19.3 million and $21.5 million , respectively, has been classified as Obligation for Consolidated Inventory Not Owned on the Consolidated Balance Sheets. The decrease in this balance from December 31, 2017 is related primarily to a decrease in the number of land purchase agreements that had deposits and prepaid acquisition and development costs that exceeded certain thresholds resulting in the remaining purchase price of the lots to be recorded in inventory not owned, partially offset by an increase in the aggregate purchase amount of land contracts with specific performance requirements.
Property, Plant and Equipment, Policy [Policy Text Block]	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) 2018 2017 Land, building and improvements $ 11,824 (a) $ 11,823 Office furnishings, leasehold improvements, computer equipment and computer software 29,920 30,409 Transportation and construction equipment 10,064 10,067 Property and equipment 51,808 52,299 Accumulated depreciation (22,413 ) (25,483 ) Property and equipment, net $ 29,395 $ 26,816 (a) Includes the Company’s home office building in Columbus, Ohio that met the sale classification criteria for the period ended September 30, 2018 as it was being actively marketed. The carrying value of the building as of December 31, 2018 was $5.6 million . The Company measures assets held for sale at fair value on a nonrecurring basis and records impairment charges when the assets are deemed to be impaired. Assets held for sale are reported at the lower of cost or fair value. Costs to sell are accrued separately. The Company estimated the fair value of the building using the market values for similar properties, and the building was considered a Level 2 asset as defined in ASC 820, “Fair Value Measurements.” During the twelve months ended December 31, 2018 , the Company did not record any impairment charges on its asset held for sale. Estimated Useful Lives Building and improvements 35 years Office furnishings, leasehold improvements, computer equipment and computer software 3-7 years Transportation and construction equipment 5-25 years Depreciation expense was $5.6 million , $4.1 million and $3.6 million in 2018, 2017 and 2016 , respectively.
Other Assets [Policy Text Block]	Other Assets. Other assets at December 31, 2018 and 2017 consisted of the following:. Year Ended December 31, (In thousands) 2018 2017 Development reimbursement receivable from local municipalities $ 13,632 $ 14,981 Mortgage servicing rights 6,477 7,821 Prepaid expenses 8,605 9,022 Prepaid acquisition costs 7,873 5,634 Other 24,207 23,677 Total other assets $ 60,794 $ 61,135
Extended Product Warranty, Policy [Policy Text Block]	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 (as described further in Note 8 to our Consolidated Financial Statements) under the Company’s warranty programs. Warranty reserves are recorded for warranties under our Home Builder’s Limited Warranty (“HBLW”) and our 30-year (offered on all homes sold after April 25, 1998 and on or before December 1, 2015 in all of our markets except our Texas markets), 15-year (offered on all homes sold after December 1, 2015 in all of our markets except our Texas markets) and 10-year (offered on all homes sold in our Texas markets) transferable structural warranty. 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 home 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, 2018 and 2017 , warranty reserves of $26.5 million and $26.1 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. Please 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.
InsuranceDeductibleReservesPolicyPolicyTextBlock	Self-insurance Reserves. Self-insurance reserves are made for estimated liabilities associated with employee health care, workers’ compensation, and general liability insurance. For 2018 , our self-insurance limit for employee health care was $250,000 per covered person per contract period, with stop loss insurance covering amounts in excess of $250,000 . In 2019, our stop loss insurance will now cover amounts in excess of $275,000 . Our workers’ compensation claims are insured by a third party and carry a deductible of $250,000 per claim, except for workers compensation claims made in the State of Ohio where the Company is self-insured. Our self-insurance limit for Ohio workers’ compensation is $500,000 per claim, with stop loss insurance covering all amounts in excess of this limit. 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 deductible. Effective for home closings occurring on or after July 1, 2017, the Company renewed its general liability insurance coverage which, among other things, changed the structure of our completed operations/construction defect deductible to $10.0 million for the Company (for closings prior to July 1, 2017, our completed operations/construction defect deductible was $7.5 million for each of our regions) and decreased our third party bodily injury and property damage claims deductible to $250,000 (a decrease from $500,000 for closings prior to July 1, 2017). The Company records a reserve for general liability claims falling below the Company’s deductible. 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, 2018 and 2017 , self-insurance reserves of $2.7 million and $2.4 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. The Company recorded expenses totaling $9.2 million , $8.9 million and $6.5 million for all self-insured and general liability claims during the years ended December 31, 2018, 2017 and 2016 , respectively.
Guarantees, Indemnifications and Warranties Policies [Policy Text Block]	Guarantees and Indemnities. Guarantee and indemnity liabilities are established by charging the applicable income statement or balance sheet line, depending on the nature of the guarantee or indemnity, and crediting a liability. M/I Financial provides a limited-life guarantee on loans sold to certain third parties and estimates its actual liability related to the guarantee and any indemnities subsequently provided to the purchaser of the loans in lieu of loan repurchase based on historical loss experience. Actual future costs associated with loans guaranteed or indemnified could differ materially from our current estimated amounts. The Company has also provided certain other guarantees and indemnities in connection with the purchase and development of land, including environmental indemnities, and guarantees of the completion of land development. The Company estimates these liabilities based on the estimated cost of insurance coverage or estimated cost of acquiring a bond in the amount of the exposure. Actual future costs associated with these guarantees and indemnities could differ materially from our current estimated amounts. At December 31, 2018 and 2017 , guarantees and indemnities of $0.7 million and $1.0 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets.
Other Liabilities [Policy Text Block]	Other Liabilities. Other liabilities at December 31, 2018 and 2017 consisted of the following: Year Ended December 31, (In thousands) 2018 2017 Accruals related to land development $ 46,073 $ 37,180 Warranty 26,459 26,133 Payroll and other benefits 31,428 28,128 Other 46,091 40,093 Total other liabilities $ 150,051 $ 131,534
Segment Reporting, Policy [Policy Text Block]	Segment Reporting. The application of segment reporting requires significant judgment in determining our operating segments. Operating segments are defined as a component of an enterprise for which discrete financial information is available and is reviewed regularly by the Company’s chief operating decision makers to evaluate performance, make operating decisions and determine how to allocate resources. The Company’s chief operating decision makers evaluate the Company’s performance in various ways, including: (1) the results of our 16 individual homebuilding operating segments and the results of our financial services operations; (2) the results of our three homebuilding regions; and (3) our consolidated financial results. In accordance with ASC 280, Segment Reporting (“ASC 280”), we have identified each homebuilding division as an operating segment because each homebuilding division engages in business activities from which it earns revenue, primarily from the sale and construction of single-family attached and detached homes, acquisition and development of land, and the occasional sale of lots to third parties. Our financial services operations generate revenue primarily from the origination, sale and servicing of mortgage loans and title services primarily for purchasers of the Company’s homes and are included in our financial services reportable segment. Corporate is a non-operating segment that develops and implements strategic initiatives and supports our operating segments by centralizing key administrative functions such as accounting, finance, treasury, information technology, insurance and risk management, litigation, marketing and human resources. In accordance with the aggregation criteria defined in ASC 280, we have determined our reportable segments as follows: Midwest homebuilding, Southern homebuilding, Mid-Atlantic homebuilding and financial services operations. The homebuilding operating segments included in each reportable segment have been aggregated because they share similar aggregation characteristics as prescribed in ASC 280 in the following regards: (1) long-term economic characteristics; (2) historical and expected future long-term gross margin percentages; (3) housing products, production processes and methods of distribution; and (4) geographical proximity. We may, however, be required to reclassify our reportable segments if markets that currently are being aggregated do not continue to share these aggregation characteristics.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition. On January 1, 2018, we adopted ASC 606, Revenue from Contracts from Customers (“ASC 606”), using the modified retrospective transition method, which includes a cumulative catch-up in retained earnings on the initial date of adoption for existing contracts (those contracts under which obligations have not been completed) as of, and new contracts after, January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605, Revenue Recognition (“ASC 605”) . We did not have any material adjustments to our 2018 results under ASC 606. Revenue from the sale of a home and revenue from the sale of land to third parties are recognized in the financial statements on the date of closing (point in time) if delivery has occurred, title has passed, all performance obligations have been met (see definition of performance obligations below), 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 in exchange for the home or land. 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 subservice 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, 2018 and 2017 , we retained mortgage servicing rights of 2,282 and 3,094 loans, respectively, for a total value of $6.5 million and $7.8 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. 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 contracts to sell homes 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 third party land contracts may include multiple performance obligations; however, revenue expected to be recognized 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 generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within general, selling and administrative expenses as part of our sales and marketing expenses. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The following table presents our revenues disaggregated by geography: Year Ended December 31, (In thousands) 2018 2017 (a) 2016 (a) Midwest homebuilding $ 933,119 $ 742,577 $ 637,894 Southern homebuilding 925,404 730,482 602,273 Mid-Atlantic homebuilding 375,563 439,219 409,149 Financial services (b) 52,196 49,693 42,011 Total revenue $ 2,286,282 $ 1,961,971 $ 1,691,327 (a) As noted above, prior period amounts have not been adjusted under the cumulative catch-up transition method. (b) Revenues include $3.6 million and $0.7 million of hedging gains and $3.0 million related to hedging losses for the years ended December 31, 2018 , 2017 and 2016 , respectively. Hedging gains (losses) do not represent revenues recognized from contracts with customers. The following table presents our revenues disaggregated by revenue source: Year Ended December 31, (Dollars in thousands) 2018 2017 (a) 2016 (a) Housing $ 2,217,197 $ 1,878,572 $ 1,610,496 Land sales 16,889 33,706 38,820 Financial services (b) 52,196 49,693 42,011 Total revenue $ 2,286,282 $ 1,961,971 $ 1,691,327 (a) As noted above, prior period amounts have not been adjusted under the cumulative catch-up transition method. (b) Revenues include $3.6 million and $0.7 million of hedging gains and $3.0 million related to hedging losses for the years ended December 31, 2018 , 2017 and 2016 , respectively. Hedging gains (losses) do not represent revenues recognized from contracts with customers.
Cost of Sales, Policy [Policy Text Block]	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 Tax, Policy [Policy Text Block]	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. During the fourth quarter of 2017, the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) was enacted which, among other things, reduced the corporate income tax rate from 35% to 21%. Please see Note 14 to our Consolidated Financial Statements for further discussion. 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. Please see Note 14 to our Consolidated Financial Statements for more information regarding our deferred tax assets.
Earnings Per Share, Policy [Policy Text Block]	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. Please see Note 13 to our Consolidated Financial Statements for more information regarding our earnings per share calculation.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation. We measure and recognize compensation expense associated with our grant of equity-based awards in accordance with ASC 718, Compensation-Stock Compensation (“ASC 718”), which generally requires that companies measure and recognize stock-based compensation expense in an amount equal to the fair value of share-based awards granted under compensation arrangements over the related vesting period. We have granted share-based awards to certain of our employees and directors in the form of stock options, director stock units and performance share units (“PSU’s”). Each PSU represents a contingent right to receive one common share of the Company if vesting is satisfied at the end of the performance period based on the related performance conditions and markets conditions. Determining the fair value of share-based awards requires judgment to identify the appropriate valuation model and develop the assumptions. The grant date fair value for stock option awards and PSU’s with a market condition (as defined in ASC 718) is estimated using the Black-Scholes option pricing model and the Monte Carlo simulation methodology, respectively. The grant date fair value for the director stock units and PSU’s with a performance condition (as defined in ASC 718) is based upon the closing price of our common shares on the date of grant. We recognize stock-based compensation expense for our stock option awards and PSU’s with a market condition over the requisite service period of the award while stock-based compensation expense for our director stock units, which vest immediately, is fully recognized in the period of the award. For the portion of the PSU’s awarded subject to the satisfaction of a performance condition, we recognize stock-based compensation expense on a straight-line basis over the performance period based on the probable outcome of the related performance condition. If satisfaction of the performance condition is not probable, stock-based compensation expense recognition is deferred until probability is attained and a cumulative compensation expense adjustment is recorded and recognized ratably over the remaining service period. The Company reevaluates the probability of the satisfaction of the performance condition on a quarterly basis, and stock-based compensation expense is adjusted based on the portion of the requisite service period that has passed. If actual results differ significantly from these estimates, stock-based compensation expense could be higher and have a material impact on our consolidated financial statements. Please see Note 2 to our Consolidated Financial Statements for more information regarding our stock-based compensation.
Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]	Letters of Credit and Completion Bonds. The Company provides standby letters of credit and completion bonds for development work in progress, deposits on land and lot purchase agreements and miscellaneous deposits. As of December 31, 2018 , the Company had outstanding $215.0 million of completion bonds and standby letters of credit, some of which were issued to various local governmental entities, that expire at various times through September 2026 . Included in this total are: (1) $155.4 million of performance and maintenance bonds and $42.4 million of performance letters of credit that serve as completion bonds for land development work in progress; (2) $10.3 million of financial letters of credit; and (3) $6.9 million of financial bonds. The development agreements under which we are required to provide completion bonds or letters of credit are generally not subject to a required completion date and only require that the improvements are in place in phases as houses are built and sold. In locations where development has progressed, the amount of development work remaining to be completed is typically less than the remaining amount of bonds or letters of credit due to timing delays in obtaining release of the bonds or letters of credit.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which provides guidance for revenue recognition. ASU 2014-09 affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605 and most industry-specific guidance as well as some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” ASU 2014-09’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date , which delayed the effective date of ASU 2014-09 by one year. ASU 2014-09, as amended, is effective for public companies for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Subsequent to the issuance of ASU 2014-09, the FASB has issued several ASUs, such as ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing , and ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients . These ASUs do not change the core principle of the guidance stated in ASU 2014-09. Instead, these amendments are intended to clarify and improve the operability of certain topics addressed by ASU 2014-09. These additional ASUs have the same effective date and transition requirements as ASU 2014-09, as amended. We adopted the standard, and the subsequently issued standards mentioned above, on January 1, 2018 using the modified retrospective transition method, which includes a cumulative catch-up in retained earnings on the initial date of adoption for existing contracts (those that are not completed) as of, and new contracts after, January 1, 2018. The adoption did not have a material impact on our consolidated financial statements. The amount and timing of our housing and land revenue remained substantially unchanged, and we did not have significant changes to our business processes, systems, or internal controls as a result of adopting the standard. The Company has developed the additional expanded disclosures required (please see our Significant Accounting Policies section above); however, the adoption did not have a material impact on its consolidated results of operations, financial position and cash flows. In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”). ASU 2017-05 is intended to clarify the scope of the original guidance within Subtopic 610-20 that was issued in connection with ASU 2014-09, which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 additionally added guidance for partial sales of nonfinancial assets. ASU 2017-05 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We were required to adopt ASU 2017-05 concurrent with the adoption of ASU 2014-09. The adoption of ASU 2017-05 did not have a material impact on the Company’s consolidated financial statements and disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 provides guidance on how certain cash receipts and cash payments are to be presented and classified in the statement of cash flows. For public entities, ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted the standard on January 1, 2018. The adoption of ASU 2016-15 did not modify the Company's current disclosures within the condensed consolidated statement of cash flows and did not have any impact on the Company’s consolidated financial statements and disclosures. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which provides a more robust framework for determining whether transactions should be accounted for as acquisitions (or dispositions) of assets or businesses. ASU 2017-01 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted the standard on January 1, 2018. The adoption of ASU 2017-01 did not have an impact on the Company’s consolidated financial statements and disclosures as the Company’s acquisition during the first quarter of 2018 met all requirements to be accounted for as a business acquisition. In March 2018, the FASB issued ASU 2018-05, which amends Income Taxes (Topic 740) by incorporating Staff Accounting Bulletin 118 (“SAB 118”) issued by the Securities and Exchange Commission (“SEC”) on December 22, 2017. SAB 118 provides guidance on accounting for the effects of the 2017 Tax Act. We recognized the income tax effects of the 2017 Tax Act in our consolidated financial statements for the fiscal year ended December 31, 2017 in accordance with SAB 118. Impact of New Accounting Standards. In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. ASU 2016-02 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842 ; ASU No. 2018-10, Codification Improvements to Topic 842, Leases ; and ASU No. 2018-11, Targeted Improvements (please see additional detail regarding these updates to Topic 842 below). The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The new standard is effective for us on January 1, 2019, with early adoption permitted. We adopted the new standard on its effective date. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients in transition. We expect to elect the ‘package of practical expedients’, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We do not expect to elect the use-of-hindsight with respect to determining the lease term (i.e., considering the actual outcome and updated expectations of lease renewals, termination option and purchase options). We also do not expect to elect the use of the practical expedient pertaining to land easements as our land easements, undertaken for the purpose of construction and development of inventory, are excluded by 842-10-15-1(d). We expect that this standard will have a material effect on our financial statements. While we continue to assess all of the effects of adoption, we currently believe the most significant effects relate to (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our office and model sale-leaseback operating leases; and (2) providing significant new disclosures about our leasing activities. We do not expect a significant change in our leasing activities between now and adoption. On adoption, we currently expect to recognize additional operating liabilities ranging from $18.0 million to $23.0 million , with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. The new standard also provides practical expedients for an entity’s ongoing accounting. We currently expect to elect the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also currently expect to elect the practical expedient to not separate lease and non-lease components for all of our leases. In January 2018, the FASB issued ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842 (“ASU 2018-01”), which provides an optional transition practical expedient to not evaluate under Topic 842 existing or expired land easements that were not previously accounted for as leases under the current lease guidance in Topic 840. An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date the entity adopts Topic 842; otherwise, an entity should evaluate all existing or expired land easements in connection with the adoption of the new lease requirements in Topic 842 to assess whether they meet the definition of a lease. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements in ASU 2016-02. This ASU is not expected to have a significant impact on the Company's expected impact of the adoption of ASU 2016-02 (discussed above) or its consolidated financial statements and disclosures. In July 2018, the FASB issued ASU 2018-09, Codification Improvements (“ASU 2018-09”). ASU 2018-09 amends a variety of topics in the FASB’s Accounting Standards Codification. The transition and effective date of the guidance are based on the facts and circumstances of each amendment. Some of the amendments in ASU 2018-09 do not require transition guidance and were effective upon issuance of ASU 2018-09. However, many of the amendments include transition guidance with effective dates for annual periods beginning after December 15, 2018. The Company does not believe the adoption of ASU 2018-09 will have a material impact on the Company’s consolidated financial statements and disclosures. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”) . ASU 2018-10 includes certain clarifications to address potential narrow-scope implementation issues which we are incorporating into our assessment and adoption of ASU 2016-02. The amendments in this ASU are effective in the same time-frame as ASU 2016-02 as discussed above. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”) . ASU 2018-11 allows entities to not recast comparative periods in transition to ASC 842 and instead report the comparative periods presented in the period of adoption under ASC 840. ASU 2018-11 also includes a practical expedient for lessors to not separate the lease and non-lease components of a contract. The amendments in ASU 2018-11 are effective in the same time-frame as ASU 2016-02 as discussed above. We are incorporating this ASU into our assessment and adoption of ASU 2016-02. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”) . ASU 2018-13 modifies the disclosure requirements for fair value measurements and removes the requirement to disclose (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (2) the policy for timing of transfers between levels, and (3) the valuation processes for Level 3 fair value measurements. ASU 2018-13 requires disclosure of changes in unrealized gains and losses for the period included in other comprehensive income (loss) for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For all entities, ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. We are currently evaluating the effect that this guidance will have on our consolidated financial statements and disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) (“ASU 2018-15”) . ASU 2018-15 requires entities that are customers in cloud computing arrangements to defer implementation costs if they would be capitalized by the entity in software licensing arrangements under the internal-use software guidance. The guidance may be applied retrospectively or prospectively to implementation costs incurred after the date of adoption. For public entities, ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. We are currently evaluating the effect that this guidance will have on our consolidated financial statements and disclosures. In October 2018, the FASB issued ASU 2018-16, Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (“ASU 2018-16”), which amends ASC 815, Derivatives and Hedging. The amendments in ASU 2018-16 permit use of the Overnight Index Swap Rate (OIS) rate based on Secured Overnight Financing Rate (SOFR) as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. For entities that have not already adopted ASU 2017-12, the amendments in ASU 2018-16 are required to be adopted concurrently with the amendments in ASU 2017-12. The Company intends to adopt ASU 2017-12 and ASU 2018-16 on January 1, 2019. We are currently evaluating the effect that this guidance will have on our consolidated financial statements and disclosures.

Deferred Costs, Capitalized, Prepaid, and Other Assets Disclosure [Table Text Block]	The summary of capitalized interest for the years ended December 31, 2018, 2017 and 2016 is as follows: Year Ended December 31, (In thousands) 2018 2017 2016 Capitalized interest, beginning of period $ 17,169 $ 16,012 $ 16,740 Interest capitalized to inventory 29,053 21,484 17,685 Capitalized interest charged to cost of sales (25,457 ) (20,327 ) (18,413 ) Capitalized interest, end of year $ 20,765 $ 17,169 $ 16,012 Interest incurred $ 49,537 $ 40,358 $ 35,283
Property, Plant and Equipment [Table Text Block]	Following are the major classes of depreciable assets and their estimated useful lives: Year Ended December 31, (In thousands) 2018 2017 Land, building and improvements $ 11,824 (a) $ 11,823 Office furnishings, leasehold improvements, computer equipment and computer software 29,920 30,409 Transportation and construction equipment 10,064 10,067 Property and equipment 51,808 52,299 Accumulated depreciation (22,413 ) (25,483 ) Property and equipment, net $ 29,395 $ 26,816 (a) Includes the Company’s home office building in Columbus, Ohio that met the sale classification criteria for the period ended September 30, 2018 as it was being actively marketed. The carrying value of the building as of December 31, 2018 was $5.6 million . The Company measures assets held for sale at fair value on a nonrecurring basis and records impairment charges when the assets are deemed to be impaired.
