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; 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, 2016 and 2015 , 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 $1.1 million and $2.9 million at December 31, 2016 and 2015 , 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 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, 2016 , 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, 2016 and December 31, 2015 , 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, 2016, 2015 and 2014 is as follows: Year Ended December 31, (In thousands) 2016 2015 2014 Capitalized interest, beginning of period $ 16,740 $ 15,296 $ 13,802 Interest capitalized to inventory 17,685 18,410 17,937 Capitalized interest charged to cost of sales (18,413 ) (16,966 ) (16,443 ) Capitalized interest, end of year $ 16,012 $ 16,740 $ 15,296 Interest incurred $ 35,283 $ 35,931 $ 31,302 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 2016 , we decreased our total investment in such joint venture arrangements by $9.0 million from $37.0 million at December 31, 2015 to $28.0 million at December 31, 2016 , which was driven primarily by our increased lot distributions from joint venture arrangements during 2016 of $28.1 million , offset, in part, by our cash contributions to our joint venture arrangements during 2016 of $21.7 million . 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 arrangements. As of both December 31, 2016 and December 31, 2015 , 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 company; 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, 2016 and December 31, 2015 ranged from 25% to 74% . 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. We believe that the Company’s maximum exposure related to its investment in these joint venture arrangements as of December 31, 2016 is the amount invested of $28.0 million , 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. 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, 2016 , we have determined that no LLC in which we have an interest met the requirements of a VIE. As of December 31, 2015 , we determined that one of the LLCs in which we had an interest at the time met the requirements of a VIE due to a lack of equity at risk in the entity. However, we determined that we did not have substantive control over that VIE as we did not have the ability to control the activities that most significantly impact its economic performance. As a result, we were not required to consolidate the VIE into our consolidated financial statements, and we instead recorded the VIE in Investment in Joint Venture Arrangements on our Consolidated Balance Sheets as of December 31, 2015 . 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, 2016 and 2015 , we have concluded that we were not the primary beneficiary of any VIEs from which we are purchasing land under option or purchase agreements. Other than as described below in “Consolidated Inventory Not Owned,” the Company currently believes that its maximum exposure as of December 31, 2016 related to our land option agreements is equal to the amount of the Company’s outstanding deposits and prepaid acquisition costs, which totaled $44.7 million , including cash deposits of $29.9 million , prepaid acquisition costs of $4.7 million , letters of credit of $4.5 million and $5.6 million of other non-cash deposits. Consolidated Inventory Not Owned and Related Obligation . At December 31, 2016 and December 31, 2015 , Consolidated Inventory Not Owned was $7.5 million and $6.0 million , respectively. At December 31, 2016 and 2015 , the corresponding liability of $7.5 million and $6.0 million , respectively, has been classified as Obligation for Consolidated Inventory Not Owned on the Consolidated Balance Sheets. 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) 2016 2015 Land, building and improvements $ 11,823 $ 11,823 Office furnishings, leasehold improvements, computer equipment and computer software 25,895 25,676 Transportation and construction equipment (a) 10,075 102 Property and equipment 47,793 37,601 Accumulated depreciation (25,494 ) (24,704 ) Property and equipment, net $ 22,299 $ 12,897 Estimated Useful Lives Building and improvements 35 years Office furnishings, leasehold improvements, computer equipment and computer software 3-7 years Transportation and construction equipment (a) 5-25 years (a) During the first quarter of 2016, the Company purchased an airplane for $9.9 million . The asset is included in the table above within Transportation and Construction Equipment and within Property and Equipment - Net in our Consolidated Balance Sheets. Depreciation is computed using the straight-line method over the respective estimated useful lives of the parts of the airplane. Maintenance and repair expenditures are charged to selling, general and administrative expense as incurred. Depreciation expense was $3.6 million , $2.3 million and $2.0 million in 2016, 2015 and 2014 , respectively. Other Assets. Other assets at December 31, 2016 and 2015 consisted of the following:. Year Ended December 31, (In thousands) 2016 2015 Development reimbursement receivable from local municipalities $ 15,698 $ 13,421 Mortgage servicing rights 11,443 7,526 Prepaid expenses 11,227 6,036 Prepaid acquisition costs 4,740 4,144 Other 19,818 15,015 Total other assets $ 62,926 $ 46,142 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 described above under the Company’s warranty programs. Reserves are recorded for warranties under the following warranty programs: • Home Builder’s Limited Warranty (“HBLW”); and • 30, 15 or 10-year transferable structural warranty, depending on sales date and state. 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. 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, 2016 and 2015 , warranty reserves of $27.7 million and $14.3 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. The increase in warranty reserves from 2015 to 2016 is related to stucco-related repairs in certain of our Florida communities. Please refer to Note 8 of our Consolidated Financial Statements for additional information related to our warranty reserves. Self-insurance Reserves. Self-insurance reserves are made for estimated liabilities associated with employee health care, workers’ compensation, and general liability insurance. For 2016 , our self-insurance limit for employee health care was $250,000 per claim per year, with stop loss insurance covering amounts in excess of $250,000 . 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. The Company generally has a $7.5 million completed operations/construction defect deductible per occurrence by region and a $24.8 million deductible in the aggregate, with a $500,000 deductible for all other types of claims. 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, 2016 and 2015 , self-insurance reserves of $1.8 million and $1.6 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. The Company recorded expenses totaling $6.5 million , $6.1 million and $7.8 million for all self-insured and general liability claims during the years ended December 31, 2016, 2015 and 2014 , 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 of the exposure. Actual future costs associated with these guarantees and indemnities could differ materially from our current estimated amounts. At December 31, 2016 and 2015 , guarantees and indemnities of $1.3 million and $1.4 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. Other Liabilities. Other liabilities at December 31, 2016 and 2015 consisted of the following: Year Ended December 31, (In thousands) 2016 2015 Accruals related to land development $ 35,417 $ 27,867 Warranty 27,732 14,282 Payroll and other benefits 26,140 21,395 Other 33,873 30,126 Total other liabilities $ 123,162 $ 93,670 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 15 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 as 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. Revenue from the sale of a home is recognized when the delivery has occurred, title has passed, the risks and rewards of ownership are transferred to the buyer, and an adequate initial and continuing investment by the homebuyer is received, or when the loan has been sold to a third-party investor. Revenue for homes that close to the buyer having a down payment of 5% or greater, home deliveries financed by third parties, and all home deliveries insured under Federal Housing Administration (“FHA”), U.S. Veterans Administration (“VA”) and other government-insured programs are recorded in the consolidated financial statements on the date of closing. Revenue related to all other home deliveries initially funded by M/I Financial, our 100%-owned subsidiary, is recorded on the date that M/I Financial sells the loan to a third-party investor, because the receivable from the third-party investor is not subject to future subordination, and the Company has transferred to this investor the usual risks and rewards of ownership that is in substance a sale and does not have a substantial continuing involvement with the home. 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 set up with the subservicer. 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. Generally, all of the financial services mortgage loans and related servicing rights are sold to third party investors within two to three weeks of origination; however, M/I Financial began retaining a portion of mortgage loan servicing rights during 2012. As of December 31, 2016 and 2015 , we retained mortgage servicing rights of 4,445 and 2,818 loans, respectively, for a total value of $11.4 million and $7.5 million , respectively. We recognize financial services revenue associated with our title operations as homes are closed, closing services are rendered, and title policies are issued, all of which generally occur simultaneously as each home is closed. All of the underwriting risk associated with title insurance policies is transferred to third-party insurers. 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: la

Stock Based Compensation [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Stock-Based and Deferred Compensation Stock Incentive Plans The Company has an equity compensation plan, the M/I Homes, Inc. 2009 Long-Term Incentive Plan (the “2009 LTIP”) which has been amended from time to time. The 2009 LTIP was approved by our shareholders and is administered by the Compensation Committee of our Board of Directors. Under the 2009 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 the 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 3,900,000 common shares, of which 1,903,245 remain available for grant at December 31, 2016 . The 2009 LTIP replaced the M/I Homes, Inc. 1993 Stock Incentive Plan as Amended (the “1993 Plan”), which expired by its terms on April 22, 2009. Awards outstanding under 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 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, 2016 , relating to the stock options awarded under 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, 2015 2,108,628 $ 22.21 5.83 $ 6,300 Granted 399,500 16.85 Exercised (14,600 ) 12.43 Forfeited (184,400 ) 39.52 Options outstanding at December 31, 2016 2,309,128 $ 19.96 5.93 $ 13,773 Options vested or expected to vest at December 31, 2016 2,247,093 $ 19.95 5.87 $ 13,460 Options exercisable at December 31, 2016 1,573,278 $ 19.90 4.88 $ 10,019 (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, 2016, 2015 and 2014 was $0.1 million , $0.7 million and $1.6 million , respectively. The fair value of our five-year service-based stock options granted during the years ended December 31, 2016, 2015 and 2014 was established at the date of grant using the Black-Scholes pricing model, with the weighted average assumptions as follows: Year Ended December 31, 2016 2015 2014 Risk-free interest rate 1.34 % 1.72 % 1.75 % Expected volatility 47.20 % 56.37 % 57.99 % Expected term (in years) 5.7 5.6 5.6 Weighted average grant date fair value of options granted during the period $ 7.57 $ 11.07 $ 12.64 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 2009 LTIP and the 1993 Plan was $3.3 million , $3.2 million , and $2.7 million for the years ended December 31, 2016, 2015 and 2014 , respectively. As of December 31, 2016 , there was a total of $7.0 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 1.9 years for the service awards. Director Stock Units Under the 2009 LTIP, the Company awarded its non-employee directors a total of 15,000 stock units during the year ended December 31, 2016 and 2015 , respectively, and 17,500 stock units during the year ended December 31, 2014. 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 $0.3 million in 2016 , $0.3 million in 2015 and $0.4 million in 2014 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, 2016 , 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 16, 2016 , February 17, 2015 and February 18, 2014 , the Company awarded its executive officers (in the aggregate) a target number of performance share units (“PSU’s”) equal to 79,108 , 56,389 and 50,439 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 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 $16.85 and $15.75 for the 2016 PSU’s, respectively, $21.28 and $18.92 for the 2015 PSU’s, respectively, and $23.79 and $21.00 for the 2014 PSU’s, respectively. 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 $0.3 million in stock-based compensation expense during 2016 related to the Market Condition portion of the 2016, 2015 and 2014 PSU awards. There was a total of $0.2 million of unrecognized stock-based compensation expense related to the Market Condition portion of the 2016 and 2015 PSU awards as of December 31, 2016 . At December 31, 2016 , the Market Condition for the 2014 PSU awards was met, and the company recorded $0.1 million of stock-based compensation expense. Based on these results and board approval, the Company issued 15,130 common shares during the first quarter of 2017 to the holders of the 2014 PSU’s with respect to the portion of the 2014 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, 2016 , the Company had not recognized any stock-based compensation expense related to the Performance Condition portion of the 2016 PSU awards. If the Company achieves the minimum performance levels for the Performance Condition to be met for the 2016 awards, the Company would record unrecognized stock-based compensation expense of $0.5 million as of December 31, 2016 , for which $0.2 million would be immediately recognized had attainment been probable at December 31, 2016 . The Company recognized $0.2 million of stock-based compensation expense related to the Performance Condition portion of the 2015 PSU awards during 2016 based on the probability of attaining the performance condition. The Company has $0.2 million of unrecognized stock-based compensation expense for the 2015 PSU awards at December 31, 2016 . The Company recognized $1.1 million of stock-based compensation expense for the 2014 PSU awards as of December 31, 2016 which met the maximum performance level at December 31, 2016 . Based on these results and board approval, the Company issued 60,528 common shares during the first quarter of 2017 to the holders of the 2014 PSU’s with respect to the portion of the 2014 PSU’s 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 $0.1 million , $0.3 million and $0.4 million for the years ended December 31, 2016, 2015 and 2014 . 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 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 , less than $0.1 million and $0.2 million , respectively, during the years ended December 31, 2016, 2015 and 2014 . As of December 31, 2016 , there were a total of 46,049 equity units with a value of $1.0 million outstanding under the Plans. The aggregate fair market value of these units at December 31, 2016 , based on the closing price of the underlying common shares, was approximately $1.6 million , and the associated deferred tax benefit the Company would recognize if the outstanding units were distributed was $1.1 million as of December 31, 2016 . 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 $1.4 million , $1.2 million and $1.0 million expense for the years ended December 31, 2016, 2015 and 2014 , respectively.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2016
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 best-efforts 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 twelve months. Some IRLCs are committed to a specific third party investor through the use of best-efforts 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. 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 best-efforts contract or by FMBSs. The FMBSs are classified and accounted for as non-designated derivative instruments, with gains and losses recorded in current earnings.

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 tables below show the level and measurement of assets measured on a non-recurring basis for the years ended December 31, 2016 and 2015 : Year Ended December 31, Description (in thousands) Hierarchy 2016 2015 (2) 2014 (2) Adjusted basis of inventory (1) Level 3 $ 12,921 $ 11,885 $ 3,730 Total losses 3,992 3,638 3,457 Initial basis of inventory (3) $ 16,913 $ 15,523 $ 7,187 (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 2016 and 2015 . The total loss for these joint venture arrangements was $1.0 million for 2014 . Financial Instruments Counterparty Credit Risk. To reduce the risk associated with accounting 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, 2016 and 2015 . The objective of the fair value measurement is defined 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, 2016 and 2015 : 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, Best-Efforts Contracts for Committed IRLCs and Mortgage Loans Held for Sale, Convertible Senior Subordinated Notes due 2017, Convertible Senior Subordinated Notes due 2018 and Senior Notes due 2021. The fair value of these financial instruments was determined based upon market quotes at December 31, 2016 and 2015 . 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 the year ended December 31, 2016 fluctuated with the Alternate Base Rate or the Eurodollar Rate for the Company’s $400 million unsecured revolving credit facility dated July 18, 2013, as amended (the “Credit Facility”), and thus the carrying value is a reasonable estimate of fair value. Refer to Note 11 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, dated June 24, 2016 (the “MIF Mortgage Warehousing Agreement”), and (2) a $15 million mortgage repurchase agreement, dated November 3, 2015 , as amended on October 31, 2016 (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 the Company during 2016 fluctuated with LIBOR. Refer to Note 11 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 $37.7 million and $42.5 million represent potential commitments at December 31, 2016 and 2015 , 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.

Homes under construction include homes that are in various stages of construction. As of December 31, 2016 and 2015 , we had 996 homes (with a carrying value of $199.4 million ) and 872 homes (with a carrying value of $184.3 million ), respectively, included in homes under construction that were not subject to a sales contract. Model homes and furnishings include homes that are under construction or have been completed and are being used as sales models. The amount also includes the net book value of furnishings included in our model homes. Depreciation on model home furnishings is recorded using an accelerated method over the estimated useful life of the assets, which is typically three years. The Company assesses inventory for recoverability on a quarterly basis. Refer to Notes 1 and 3 of our Consolidated Financial Statements for additional details relating to our procedures for evaluating our inventories for impairment. Land purchase deposits include both refundable and non-refundable amounts paid to third party sellers relating to the purchase of land. On an ongoing basis, the Company evaluates the land option agreements relating to the land purchase deposits. In the period during which the Company makes the decision not to proceed with the purchase of land under an agreement, the Company writes off any deposits and accumulated pre-acquisition costs relating to such agreement.

Related Party Transactions Disclosure [Text Block]	Transactions with Related Parties The Company made a contribution of $0.4 million in 2016 to the M/I Homes Foundation, a charitable organization having certain officers and directors of the Company on its Board of Trustees. The Company had a receivable of $0.2 million at both December 31, 2016 and 2015 due from an executive officer, relating to amounts owed to the Company for split-dollar life insurance policy premiums. The Company will collect the receivable either directly from the executive officer, if employment terminates other than by death, or from the executive officer’s beneficiary, if employment terminates due to death of the executive officer. As of December 31, 2015 , we also had an outstanding loan to one of our joint venture arrangements for $2.5 million in which we are one of the partners in the joint venture, which was paid in full during 2016. The receivable is recorded in Other Assets on the Consolidated Balance Sheets.

Investment in Unconsolidated LLCs [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, they 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, 2016 is the total amount invested of $28.0 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. Included in the Company’s Investment in Joint Venture Arrangements at December 31, 2016 and December 31, 2015 were $0.1 million and $0.4 million , respectively, of capitalized interest and other costs. The Company evaluates its investment in joint venture arrangements for potential impairment on a quarterly basis. If the fair value of the investment (see Notes 1 and 3 of 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 as of December 31, 2016 and 2015 and for the years ended December 31, 2016, 2015 and 2014 is as follows: Summarized Condensed Combined Balance Sheets: December 31, (In thousands) 2016 2015 Assets: Single-family lots, land and land development costs (a) (b) $ 30,794 $ 53,754 Other assets 1,040 5,499 Total assets $ 31,834 $ 59,253 Liabilities and partners’ equity: Liabilities: Notes payable $ 1,287 $ 7,025 Other liabilities 2,723 2,190 Total liabilities 4,010 9,215 Partners’ equity: Company’s equity (a) (b) $ 16,015 $ 24,367 Other equity 11,809 25,671 Total partners’ equity $ 27,824 $ 50,038 Total liabilities and partners’ equity $ 31,834 $ 59,253 (a) For the years ended December 31, 2016 and 2015 , impairment expenses and other miscellaneous adjustments totaling $0.5 million and $4.8 million , respectively, were excluded from the table above. (b) For the years ended December 31, 2016 and 2015 , the table above excludes the Company’s investment in joint development arrangements for which a special purpose entity was not established, totaling $12.5 million and $17.4 million , respectively.

Guarantees [Abstract]
Guarantees [Text Block]	Guarantees and Indemnifications In the ordinary course of business, M/I Financial, a 100%-owned subsidiary of M/I Homes, Inc., 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 $27.6 million and $12.2 million were covered under the above guarantees as of December 31, 2016 and 2015 , respectively. The increase in loans covered by these guarantees from December 31, 2015 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 the above loans was deferred at December 31, 2016 , 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 received inquiries concerning underwriting matters from purchasers of its loans regarding certain loans totaling approximately $0.9 million and $1.3 million at December 31, 2016 and 2015 , 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, 2016 and 2015 , the total of all loans indemnified to third party insurers relating to the above agreements was $1.6 million and $2.2 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 $0.9 million and $1.2 million at December 31, 2016 and 2015 , respectively, which is management’s best estimate of the Company’s liability.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies Warranty 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. 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) or 10-year (offered on all homes sold in our Texas markets) transferable structural warranty in Other Liabilities on the Company’s Consolidated Balance Sheets. The warranty reserves for the HBLW are established as a percentage of average sales price and adjusted based on historical payment patterns determined, generally, by geographic area and recent trends. Factors that are given consideration in determining the HBLW reserves include: (1) the historical range of amounts paid per average sales price on a home; (2) type and mix of amenity packages added to the home; (3) any warranty expenditures not considered to be normal and recurring; (4) timing of payments; (5) improvements in quality of construction expected to impact future warranty expenditures; and (6) conditions that may affect certain projects and require a different percentage of average sales price for those specific projects. Changes in estimates for warranties occur due to changes in the historical payment experience and differences between the actual payment pattern experienced during the period and the historical payment pattern used in our evaluation of the warranty reserve balance at the end of each quarter. Actual future warranty costs could differ from our current estimated amount. Our warranty reserves for our transferable structural warranty programs are established on a per-unit basis. While the structural warranty reserve is recorded as each house is delivered, the sufficiency of the structural warranty per unit charge and total reserve is re-evaluated on an annual basis, with the assistance of an actuary, using our own historical data and trends, industry-wide historical data and trends, and other project specific factors. The reserves are also evaluated quarterly and adjusted if we encounter activity that is inconsistent with the historical experience used in the annual analysis. These reserves are subject to variability due to uncertainties regarding structural defect claims for products we build, the markets in which we build, claim settlement history, insurance and legal interpretations, among other factors. 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. Our warranty reserve amounts are based upon historical experience and geographic location. Our warranty reserves are included in Other Liabilities in the Company’s Consolidated Balance Sheets. A summary of warranty activity for the years ended December 31, 2016, 2015 and 2014 is as follows: Year Ended December 31, (In thousands) 2016 2015 2014 Warranty reserves, beginning of period $ 14,282 $ 12,671 $ 12,291 Warranty expense on homes delivered during the period 10,452 8,812 7,311 Changes in estimates for pre-existing warranties 3,304 5,160 5,223 Charges related to stucco-related claims (a) 19,409 — — Settlements made during the period (19,715 ) (12,361 ) (12,154 ) Warranty reserves, end of period $ 27,732 $ 14,282 $ 12,671 (a) Estimated stucco-related claim costs, as described below, have been included in warranty accruals. 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. In 2015 , we repaired certain of the identified homes and accrued for the estimated future cost of repairs for the other identified homes on which repairs had yet to be completed. The aggregate amounts of such repair costs and accruals were not material, and the warranty reserve for identified homes in need of more than minor repair at December 31, 2015 was $0.5 million . During the early part of 2016, we received an increased number of stucco-related claims and recorded expense of $2.2 million and $2.8 million during the first and second quarters of 2016, respectively, to reflect the cost of these claims. Furthermore, as a result of these increasing claims, we commenced a review of the stucco issues to determine their causes and to enable us to make a reasonable estimate of the overall cost of stucco-related repairs to homes in our Florida communities. Our review included an analysis of a number of factors: (1) the date of delivery of each home in our Florida communities and the expiration date of the 10-year statutory period of repose and contractual warranty period with respect to each such home; (2) the number of each type of home (i.e., one story, 1.5 stories or 2 stories); (3) our stucco-related claims experience with respect to each type of home and each individual community; and (4) other relevant factors and observations gained from the field. As a result of this review, in the third quarter of 2016, we recorded an additional charge of $14.5 million for a total 2016 charge of $19.4 million for repair costs for (1) homes in our Florida communities that we had identified as needing repair but have not yet completed the repair and (2) estimated repair costs for homes in our Florida communities that we have not yet identified as needing repair but that may require repair in the future. These charges are included as changes in estimate within our warranty reserve. The remaining reserve for the both known repair costs and an estimate of future costs of stucco-related repairs at December 31, 2016 included within our warranty reserve was $11.9 million . We believe that this amount is sufficient to cover both known and estimated future repair costs as of December 31, 2016 . 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 repairs costs, which revision could be material. We also are continuing to investigate the extent to which we may be able to 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, 2016 , we are unable to estimate an amount, if any, that we believe is probable that we will recover from these sources and, accordingly, we have not recorded a receivable for estimated recoveries nor included an estimated amount of recoveries in determining our warranty reserves. Performance Bonds and Letters of Credit At December 31, 2016 , the Company had outstanding approximately $154.3 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 2024 . Included in this total are: (1) $108.9 million of performance and maintenance bonds and $31.5 million of performance letters of credit that serve as completion bonds for land development work in progress; (2) $6.2 million of financial letters of credit, of which $4.5 million represent deposits on land and lot purchase agreements; and (3) $7.7 million of financial bonds. Land Option Contracts and Other Similar Contracts At December 31, 2016 , the Company also had options and contingent purchase agreements to acquire land and developed lots with an aggregate purchase price of approximately $556.2 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 December 31, 2016 and 2015 , we had $0.3 million and $0.6 million reserved for legal expenses, respectively.

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. Following are details relating to such CDD bond obligations issued and outstanding as of December 31, 2016 : Issue Date Maturity Date Interest Rate Principal Amount as of December 31, 2016 (in thousands) Principal Amount as of December 31, 2015 (in thousands) 7/15/2004 12/1/2022 6.00% $ 2,922 $ 2,922 7/15/2004 12/1/2036 6.25% 10,060 10,060 7/22/2014 11/1/2045 5.28% 535 535 Total CDD bond obligations issued and outstanding $ 13,517 $ 13,517 The Company records a liability for the estimated developer obligations that are probable and estimable and user fees that are required to be paid or transferred at the time the parcel or unit is sold to an end user. The Company reduces this liability by the corresponding Assessment assumed by property purchasers and the amounts paid by the Company at the time of closing and the transfer of the property. The Company recorded a $0.5 million and $1.0 million liability related to these CDD bond obligations as of December 31, 2016 and December 31, 2015 , respectively, along with the related inventory infrastructure.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	Debt Notes Payable - Homebuilding The Credit Facility provides an aggregate commitment amount of $400 million , including a $125 million sub-facility for letters of credit. The Credit Facility expires on October 20, 2018 . For the year ended December 31, 2016 , interest on amounts borrowed under the Credit Facility was payable at either the Alternate Base Rate plus a margin of 150 basis points, or at the Eurodollar Rate plus a margin of 250 basis points. These interest rates are subject to adjustment in subsequent periods based on the Company's leverage ratio. The Credit Facility also contains certain financial covenants. At December 31, 2016 , the Company was in compliance with all financial covenants of the Credit Facility. At December 31, 2016 , borrowing availability under the Credit Facility in accordance with the borrowing base calculation was $537.6 million , and, as a result, the full amount of the $400 million facility was available. At December 31, 2016 , there were $40.3 million of borrowings outstanding and $37.1 million of letters of credit outstanding, leaving net remaining borrowing availability of $322.6 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 ), subject to limitations on the aggregate amount invested in such Unrestricted Subsidiaries in accordance with the terms of the Credit Facility and the indenture for 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 2021 Senior Notes, the Company’s $57.5 million aggregate principal amount of 3.25% Convertible Senior Subordinated Notes due 2017 (the “2017 Convertible Senior Subordinated Notes”) and the Company’s $86.3 million aggregate principal amount of 3.0% Convertible Senior Subordinated Notes due 2018 (the “2018 Convertible Senior Subordinated 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 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 $404.5 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. As of December 31, 2015 , the Company was a party to three secured credit agreements for the issuance of letters of credit outside of the Credit Facility (collectively, the “Letter of Credit Facilities”). During 2016 , the Company terminated one Letter of Credit Facility and allowed another Letter of Credit Facility to expire. Therefore, at December 31, 2016 , the Company was party to one remaining Letter of Credit Facility, with a maturity date of September 30, 2017 , which allows for the issuance of letters of credit up to a total of $2.0 million . At December 31, 2016 and December 31, 2015 , there was $0.6 million and $2.7 million of outstanding letters of credit in aggregate under the Company’s Letter of Credit Facilities, respectively, which were collateralized with $0.6 million and $2.7 million of the Company’s cash, respectively. Notes Payable — Financial Services The MIF Mortgage Warehousing Agreement is used to finance eligible residential mortgage loans originated by M/I Financial. The Agreement provides a maximum borrowing availability of $125 million which increased to $150 million from September 25, 2016 to October 15, 2016 and from December 15, 2016 to February 2, 2017 (periods during which we typically experience higher mortgage origination volume). The MIF Mortgage Warehousing Agreement expires on June 23, 2017 . Interest on amounts borrowed under the MIF Mortgage Warehousing Agreement is payable at a per annum rate equal to the greater of (1) the floating LIBOR rate plus 250 basis points and (2) 2.75% . The MIF Mortgage Warehousing Agreement also contains certain financial covenants. At December 31, 2016 , the Company was in compliance with all financial covenants of the MIF Mortgage Warehousing Agreement. The MIF Mortgage Repurchase Facility is used to finance eligible residential mortgage loans originated by M/I Financial and is structured as a mortgage repurchase facility with a maximum borrowing availability of $15 million which increased to $35 million from December 2, 2016 through February 1, 2017 (a period during which we typically experience higher mortgage origination volume). The MIF Mortgage Repurchase Facility expires on October 30, 2017 . M/I Financial pays interest on each advance under the MIF Mortgage Repurchase Facility at a per annum rate equal to the floating LIBOR rate plus 250 or 275 basis points depending on the loan type. The MIF Mortgage Repurchase Facility also contains certain financial covenants. At December 31, 2016 , MI Financial was in compliance with all financial covenants of the MIF Mortgage Repurchase Facility. At December 31, 2016 , M/I Financial’s total combined maximum borrowing availability under the two credit facilities was $185.0 million , an increase from $150.0 million at December 31, 2015 due to the seasonal increases on the two credit facilities as described in further detail above. At December 31, 2016 and December 31, 2015 , M/I Financial had $152.9 million and $123.6 million outstanding on a combined basis under its credit facilities, respectively, and was in compliance with all financial covenants of those agreements for both periods.

The indenture governing the 2018 Convertible Senior Subordinated Notes requires the Company to repurchase the notes (subject to certain exceptions), at a holder’s option, upon the occurrence of a fundamental change (as defined in the indenture). The Company may redeem for cash any or all of the 2018 Convertible Senior Subordinated Notes (except for any 2018 Convertible Senior Subordinated Notes that the Company is required to repurchase in connection with a fundamental change), but only if the last reported sale price of the Company’s common shares exceeds 130% of the applicable conversion price for the notes on each of at least 20 applicable trading days. The 20 trading days do not need to be consecutive, but must occur during a period of 30 consecutive trading days that ends within 10 trading days immediately prior to the date the Company provides the notice of redemption. The redemption price for the 2018 Convertible Senior Subordinated Notes to be redeemed will equal 100% of the principal amount, plus accrued and unpaid interest, if any. As of both December 31, 2016 and 2015 , we had $57.5 million of our 2017 Convertible Senior Subordinated Notes outstanding.

This corresponds to an initial conversion price of approximately $23.80 per common share, which equates to approximately 2.4 million common shares. The conversion rate is subject to adjustment upon the occurrence of certain events. The 2017 Convertible Senior Subordinated Notes are fully and unconditionally guaranteed jointly and severally on a senior subordinated unsecured basis by the Guarantor Subsidiaries. The 2017 Convertible Senior Subordinated Notes are senior subordinated unsecured obligations of the Company and the Guarantor Subsidiaries, are subordinated in right of payment to our and the Guarantor Subsidiaries’ existing and future senior indebtedness and are also 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 indenture governing the 2017 Convertible Senior Subordinated Notes provides that we may not redeem the notes prior to their stated maturity date, but also contains provisions requiring the Company to repurchase the 2017 Convertible Senior Subordinated Notes (subject to certain exceptions), at a holder’s option, upon the occurrence of a fundamental change (as defined in the indenture). Senior Notes As of both December 31, 2016 and 2015 , we had $300.0 million of our 2021 Senior Notes outstanding. The 2021 Senior Notes bear interest at a rate of 6.75% per year, payable semiannually in arrears on January 15 and July 15 of each year, and mature on January 15, 2021. The 2021 Senior Notes 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. The 2021 Senior Notes 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 2021 Senior Notes contain certain covenants, as more fully described and defined in 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 2021 Senior Notes. As of December 31, 2016 , the Company was in compliance with all terms, conditions, and covenants under the indenture. The 2021 Senior Notes are fully and unconditionally guaranteed jointly and severally on a senior unsecured basis by the Guarantor Subsidiaries. The Company may redeem all or any portion of the 2021 Senior Notes on or after January 15, 2018 at a stated redemption price, together with accrued and unpaid interest thereon. The redemption price will initially be 103.375% of the principal amount outstanding, but will decline to 101.688% of the principal amount outstanding if redeemed during the 12-month period beginning on January 15, 2019, and will further decline to 100.000% of the principal amount outstanding if redeemed on or after January 15, 2020, but prior to maturity. The indenture governing our 2021 Senior Notes limits our ability to pay dividends on, and repurchase, our common shares and our 9.75% Series A Preferred Shares (the “Series A Preferred Shares”) to the amount of the positive balance in our “restricted payments basket,” as defined in the indenture. The “restricted payments basket” is equal to $125.0 million plus (1) 50% of our aggregate consolidated net income (or minus 100% of our aggregate consolidated net loss) from October 1, 2015, excluding income or loss from Unrestricted Subsidiaries, plus (2) 100% of the net cash proceeds from either contributions to the common equity of the Company after December 31, 2015 or the sale of qualified equity interests, plus other items and subject to other exceptions. The restricted payments basket was $144.9 million and $128.5 million at December 31, 2016 and 2015, respectively. The determination to pay future dividends on, or make future repurchases of, our common shares or Series A Preferred Shares will be at the discretion of our board of directors and will depend upon our results of operations, financial condition, capital requirements and compliance with debt covenants and the terms of our Series A Preferred Shares, and other factors deemed relevant by our board of directors.

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. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period when the changes are enacted. In accordance with ASC 740-10, Income Taxes (“ASC 740”) , we evaluate 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. 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, 2016 , the Company’s total deferred tax assets were $37.0 million which is offset by $6.1 million of total deferred tax liabilities for a $30.9 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) 2016 2015 Deferred tax assets: Warranty, insurance and other accruals $ 12,738 $ 8,987 Equity-based compensation 5,482 5,473 Inventory 8,223 9,528 State taxes 219 211 Net operating loss carryforward 8,483 42,556 Deferred charges 1,812 649 Total deferred tax assets $ 36,957 $ 67,404 Deferred tax liabilities: Federal effect of state deferred taxes $ 3,879 $ 5,519 Depreciation 1,947 — Prepaid expenses 256 — Total deferred tax liabilities $ 6,082 $ 5,519 Net deferred tax asset $ 30,875 $ 61,885 The provision (benefit) from income taxes consists of the following: Year Ended December 31, (In thousands) 2016 2015 2014 Current: Federal $ 1,745 $ 1,757 $ 1,766 State 2,120 883 681 $ 3,865 $ 2,640 $ 2,447 Year Ended December 31, (In thousands) 2016 2015 2014 Deferred: Federal $ 28,335 $ 28,760 $ 22,141 State 2,976 3,766 (5,641 ) $ 31,311 $ 32,526 $ 16,500 Total $ 35,176 $ 35,166 $ 18,947 For 2016, 2015 and 2014 , the Company’s effective tax rate was 38.32% , 40.45% , and 27.17% , respectively. 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) 2016 2015 2014 Federal taxes at statutory rate $ 32,125 $ 30,425 $ 24,407 State and local taxes – net of federal tax benefit 3,652 2,820 2,199 Change in valuation allowance — — (9,291 ) Change in state NOL deferred asset – net of federal tax benefit 729 1,548 1,780 Manufacturing deduction (1,298 ) — — Other (32 ) 373 (148 ) Total $ 35,176 $ 35,166 $ 18,947 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 2010. 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, 2016 , 2015 and 2014 , 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 $5.5 million of state NOL carryforwards, net of the federal benefit, at December 31, 2016 . Our state NOLs may be carried forward from one to 16 years, depending on the tax jurisdiction, with $1.5 million expiring between 2022 and 2027 and $4.0 million expiring between 2028 and 2032, absent sufficient state taxable income.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
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; 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, 2016 and 2015 , 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 $1.1 million and $2.9 million at December 31, 2016 and 2015 , 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 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, 2016 , 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, 2016 and December 31, 2015 , 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, 2016, 2015 and 2014 is as follows: Year Ended December 31, (In thousands) 2016 2015 2014 Capitalized interest, beginning of period $ 16,740 $ 15,296 $ 13,802 Interest capitalized to inventory 17,685 18,410 17,937 Capitalized interest charged to cost of sales (18,413 ) (16,966 ) (16,443 ) Capitalized interest, end of year $ 16,012 $ 16,740 $ 15,296 Interest incurred $ 35,283 $ 35,931 $ 31,302
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, 2016 , we have determined that no LLC in which we have an interest met the requirements of a VIE. As of December 31, 2015 , we determined that one of the LLCs in which we had an interest at the time met the requirements of a VIE due to a lack of equity at risk in the entity. However, we determined that we did not have substantive control over that VIE as we did not have the ability to control the activities that most significantly impact its economic performance. As a result, we were not required to consolidate the VIE into our consolidated financial statements, and we instead recorded the VIE in Investment in Joint Venture Arrangements on our Consolidated Balance Sheets as of December 31, 2015
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, 2016 and 2015 , we have concluded that we were not the primary beneficiary of any VIEs from which we are purchasing land under option or purchase agreements. Other than as described below in “Consolidated Inventory Not Owned,” the Company currently believes that its maximum exposure as of December 31, 2016 related to our land option agreements is equal to the amount of the Company’s outstanding deposits and prepaid acquisition costs, which totaled $44.7 million , including cash deposits of $29.9 million , prepaid acquisition costs of $4.7 million , letters of credit of $4.5 million and $5.6 million of other non-cash deposits.
Equity Method Investments, Policy [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 2016 , we decreased our total investment in such joint venture arrangements by $9.0 million from $37.0 million at December 31, 2015 to $28.0 million at December 31, 2016 , which was driven primarily by our increased lot distributions from joint venture arrangements during 2016 of $28.1 million , offset, in part, by our cash contributions to our joint venture arrangements during 2016 of $21.7 million . 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 arrangements. As of both December 31, 2016 and December 31, 2015 , 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 company; 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, 2016 and December 31, 2015 ranged from 25% to 74% . 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. We believe that the Company’s maximum exposure related to its investment in these joint venture arrangements as of December 31, 2016 is the amount invested of $28.0 million , 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.
Consolidated Inventory Not Owned [Policy Text Block]	Consolidated Inventory Not Owned and Related Obligation . At December 31, 2016 and December 31, 2015 , Consolidated Inventory Not Owned was $7.5 million and $6.0 million , respectively. At December 31, 2016 and 2015 , the corresponding liability of $7.5 million and $6.0 million , respectively, has been classified as Obligation for Consolidated Inventory Not Owned on the Consolidated Balance Sheets.
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) 2016 2015 Land, building and improvements $ 11,823 $ 11,823 Office furnishings, leasehold improvements, computer equipment and computer software 25,895 25,676 Transportation and construction equipment (a) 10,075 102 Property and equipment 47,793 37,601 Accumulated depreciation (25,494 ) (24,704 ) Property and equipment, net $ 22,299 $ 12,897 Estimated Useful Lives Building and improvements 35 years Office furnishings, leasehold improvements, computer equipment and computer software 3-7 years Transportation and construction equipment (a) 5-25 years (a) During the first quarter of 2016, the Company purchased an airplane for $9.9 million . The asset is included in the table above within Transportation and Construction Equipment and within Property and Equipment - Net in our Consolidated Balance Sheets. Depreciation is computed using the straight-line method over the respective estimated useful lives of the parts of the airplane. Maintenance and repair expenditures are charged to selling, general and administrative expense as incurred. Depreciation expense was $3.6 million , $2.3 million and $2.0 million in 2016, 2015 and 2014 , respectively.
Other Assets [Policy Text Block]	Other Assets. Other assets at December 31, 2016 and 2015 consisted of the following:. Year Ended December 31, (In thousands) 2016 2015 Development reimbursement receivable from local municipalities $ 15,698 $ 13,421 Mortgage servicing rights 11,443 7,526 Prepaid expenses 11,227 6,036 Prepaid acquisition costs 4,740 4,144 Other 19,818 15,015 Total other assets $ 62,926 $ 46,142
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 described above under the Company’s warranty programs. Reserves are recorded for warranties under the following warranty programs: • Home Builder’s Limited Warranty (“HBLW”); and • 30, 15 or 10-year transferable structural warranty, depending on sales date and state. 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. 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, 2016 and 2015 , warranty reserves of $27.7 million and $14.3 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. The increase in warranty reserves from 2015 to 2016 is related to stucco-related repairs in certain of our Florida communities. Please refer to Note 8 of our Consolidated Financial Statements for additional information related to our warranty reserves.
InsuranceDeductibleReservesPolicyPolicyTextBlock	Self-insurance Reserves. Self-insurance reserves are made for estimated liabilities associated with employee health care, workers’ compensation, and general liability insurance. For 2016 , our self-insurance limit for employee health care was $250,000 per claim per year, with stop loss insurance covering amounts in excess of $250,000 . 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. The Company generally has a $7.5 million completed operations/construction defect deductible per occurrence by region and a $24.8 million deductible in the aggregate, with a $500,000 deductible for all other types of claims. 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, 2016 and 2015 , self-insurance reserves of $1.8 million and $1.6 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets. The Company recorded expenses totaling $6.5 million , $6.1 million and $7.8 million for all self-insured and general liability claims during the years ended December 31, 2016, 2015 and 2014 , 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, 2016 and 2015 , guarantees and indemnities of $1.3 million and $1.4 million , respectively, are included in Other Liabilities on the Consolidated Balance Sheets.
Other Liabilities [Policy Text Block]	Other Liabilities. Other liabilities at December 31, 2016 and 2015 consisted of the following: Year Ended December 31, (In thousands) 2016 2015 Accruals related to land development $ 35,417 $ 27,867 Warranty 27,732 14,282 Payroll and other benefits 26,140 21,395 Other 33,873 30,126 Total other liabilities $ 123,162 $ 93,670
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 15 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 as 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. Revenue from the sale of a home is recognized when the delivery has occurred, title has passed, the risks and rewards of ownership are transferred to the buyer, and an adequate initial and continuing investment by the homebuyer is received, or when the loan has been sold to a third-party investor. Revenue for homes that close to the buyer having a down payment of 5% or greater, home deliveries financed by third parties, and all home deliveries insured under Federal Housing Administration (“FHA”), U.S. Veterans Administration (“VA”) and other government-insured programs are recorded in the consolidated financial statements on the date of closing. Revenue related to all other home deliveries initially funded by M/I Financial, our 100%-owned subsidiary, is recorded on the date that M/I Financial sells the loan to a third-party investor, because the receivable from the third-party investor is not subject to future subordination, and the Company has transferred to this investor the usual risks and rewards of ownership that is in substance a sale and does not have a substantial continuing involvement with the home. 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 set up with the subservicer. 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. Generally, all of the financial services mortgage loans and related servicing rights are sold to third party investors within two to three weeks of origination; however, M/I Financial began retaining a portion of mortgage loan servicing rights during 2012. As of December 31, 2016 and 2015 , we retained mortgage servicing rights of 4,445 and 2,818 loans, respectively, for a total value of $11.4 million and $7.5 million , respectively. We recognize financial services revenue associated with our title operations as homes are closed, closing services are rendered, and title policies are issued, all of which generally occur simultaneously as each home is closed. All of the underwriting risk associated with title insurance policies is transferred to third-party insurers.
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. 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, 2016 , the Company had outstanding $154.3 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 2024 . Included in this total are: (1) $108.9 million of performance and maintenance bonds and $31.5 million of performance letters of credit that serve as completion bonds for land development work in progress; (2) $6.2 million of financial letters of credit; and (3) $7.7 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]	Impact of New 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 and supersedes the revenue recognition requirements in ASC 605, Revenue Recognition , and most industry-specific guidance. This ASU also supersedes 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. Early adoption is permitted as of the original effective date for annual reporting periods beginning after December 15, 2016, 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 will have the same effective date and transition requirements as ASU 2014-09, as amended. See below for additional explanation of each of these additional ASUs. The guidance in ASU 2014-09 permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The new standard is effective for our fiscal year beginning January 1, 2018, and, at that time, we currently anticipate adopting the standard using the cumulative catch-up transition method. We anticipate this standard will not have a material impact on our consolidated financial statements. While we are continuing to assess all potential impacts of the standard, and have been involved in industry-specific discussions with the FASB on the treatment of certain items, we currently believe the most significant impact could relate to our accounting for sale of land and/or lots to third parties that have continuing performance obligations. We expect the amount and timing of our homebuilding revenue to remain substantially unchanged. Due to the complexity of certain of our land contracts, however, the actual revenue recognition treatment required under the standard for land sales will be dependent on contract-specific terms, and may vary in some instances from recognition at the time of closing. We are continuing to evaluate the impact the adoption of ASU 2014-09 may have on other aspects of our business and on our consolidated financial statements and disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”), which makes a number of changes to the current GAAP model, including changes to the accounting for equity investments and financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. ASU 2016-01 is effective for our interim and annual reporting periods beginning January 1, 2018. Early adoption of this particular guidance from ASU 2016-01 is not permitted. The Company is currently evaluating the method of adoption and impact the pronouncement will have on the Company’s consolidated financial statements and disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 will require organizations that lease assets - referred to as “lessees” - to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Under ASU 2016-02, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Lessor accounting remains substantially similar to current GAAP. In addition, disclosures of leasing activities will be expanded to include qualitative and specific quantitative information. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. ASU 2016-02 mandates a modified retrospective transition method. The Company is currently evaluating the potential impact the adoption of ASU 2016-02 will have on the Company’s consolidated financial statements and disclosures. In March 2016, the FASB issued ASU No. 2016-06, Contingent Put and Call Options in Debt Instruments (“ASU 2016-06”), which requires that embedded derivatives be separated from the host contract and accounted for separately as derivatives if certain criteria are met. One of those criteria is that the economic characteristics and risks of the embedded derivatives are not clearly and closely related to the economic characteristics and risks of the host contract (the “clearly and closely related” criterion). ASU 2016-06 clarifies the required steps for assessing whether the economic characteristics and risks of call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts, which is one of the criteria for bifurcating an embedded derivative. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. ASU 2016-06 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted for all entities. The Company does not believe the adoption of ASU 2016-06 will have a material impact on the Company’s consolidated financial statements and disclosures. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”). The amendments in this ASU are intended to improve the operability and understandability of the implementation guidance stated in ASU 2014-09 on principal versus agent considerations and whether an entity reports revenue on a gross or net basis. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public entities, ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company does not believe the adoption of ASU 2016-09 will have a material impact on the Company’s consolidated financial statements and disclosures. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing (“ASU 2016-10”). ASU 2016-10 provides guidance on identifying performance obligations and licensing. This update clarifies the guidance in ASU 2014-09 relating to identifying performance obligations and licensing. The new standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers: Narrow Scope Improvements and Practical Expedients (“ASU 2016-12”). ASU 2016-12 provides for amendments to ASU 2014-09 regarding transition, collectability, noncash consideration, and presentation of sales tax and other similar taxes. Specifically, ASU 2016-12 clarifies that, for a contract to be considered completed at transition, all or substantially all of the revenue must have been recognized under legacy GAAP. In addition, ASU 2016-12 clarifies how an entity should evaluate the collectability threshold and when an entity can recognize nonrefundable consideration received as revenue if an arrangement does not meet the standard’s contract criteria. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: 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 adoption of ASU 2016-15 will modify the Company's current disclosures and reclassifications within the condensed consolidated statement of cash flows but is not expected to have a material effect on the Company’s consolidated financial statements and disclosures.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]	Recently Adopted Accounting Standards. In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No 2016-18, Statement of Cash Flows: Restricted Cash (“ASU 2016-18”), which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for our fiscal year beginning January 1, 2018. Early adoption is permitted, and the Company elected to early adopt the new standard in the fourth quarter of 2016. The adoption of ASU 2016-18 did not have a material effect on our consolidated financial statements and disclosures. ASU 2016-18 was applied retrospectively and as such, certain financial statement line items reflected on the December 31, 2015 Consolidated Balance Sheets and the December 31, 2015 and December 31, 2014 Statement of Cash Flows were affected by the change in accounting principle.
