Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	Debt Notes Payable - Homebuilding The Credit Facility matures on July 18, 2016, and provides revolving credit financing for the Company with a maximum borrowing availability of $200 million and a sub-limit of $100 million for the issuance of letters of credit. The Credit Facility contains an uncommitted $25 million accordion feature under which its aggregate principal amount can be increased to up to $225 million, subject to certain conditions, including obtaining additional commitments from existing or new lenders. Interest on amounts borrowed under the Credit Facility is payable at a rate based on either the Alternate Base Rate plus 2.25% or at the Eurodollar Rate plus 3.25%. Borrowings under the Credit Facility are unsecured and availability is subject to, among other things, a borrowing base. The Credit Facility also contains certain financial covenants. At September 30, 2014, the Company was in compliance with all financial covenants of the Credit Facility. At September 30, 2014, borrowing availability under the Credit Facility in accordance with the borrowing base calculation was $358.6 million, so the full amount of the $200 million facility was available. There were $14.4 million borrowings outstanding and $19.6 million of letters of credit outstanding, leaving net remaining borrowing availability of $166.0 million as of September 30, 2014. 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 11), 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 2018 Senior Notes. The guarantors for the Credit Facility are the same subsidiaries that guarantee the 2018 Senior Notes, the 2017 Convertible Senior Subordinated Notes, and the 2018 Convertible Senior Subordinated Notes. The Company’s obligations under the Credit Facility are general, unsecured senior obligations of the Company and the subsidiary guarantors and rank equally in right of payment with all our 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. Refer to Note 12 for additional discussion of the Company’s Credit Facility. The Company is party to three secured credit agreements for the issuance of letters of credit outside of the Credit Facility (collectively, the “Letter of Credit Facilities”), with maturities ranging from June 1, 2015 to September 30, 2015. During the three months ended September 30, 2014, the Company extended the maturity dates on two of the Letter of Credit Facilities for an additional year to June 1, 2015 and September 30, 2015, respectively. The agreements governing the Letter of Credit Facilities contain limits for the issuance of letters of credit ranging from $5.0 million to $10.0 million, for a combined letter of credit capacity of $20.0 million, of which $2.3 million was uncommitted at September 30, 2014 and could be withdrawn at any time. At September 30, 2014 and December 31, 2013, there was $8.6 million and $13.4 million of outstanding letters of credit in aggregate under the Company's three Letter of Credit Facilities, respectively, which were collateralized with $8.8 million and $13.7 million of the Company's cash, respectively. Notes Payable — Financial Services In March 2014, M/I Financial entered into an amendment to the MIF Mortgage Warehousing Agreement, which, among other things, increased the maximum borrowing availability to $110.0 million and included an accordion feature which allows for an increase of the maximum borrowing availability of up to an additional $20.0 million (subject to certain conditions, including obtaining additional commitments from existing or new lenders), extended the expiration date to March 27, 2015, increased the maximum principal amount permitted to be outstanding at any one time in aggregate under all warehouse credit lines to $150.0 million, and, effective with the quarter ending September 30, 2014, increased M/I Financial's minimum required tangible net worth requirement from $10.0 million to $11.0 million and the minimum required liquidity requirement from $5.0 million to $5.5 million. The interest rate was also adjusted to a per annum rate equal to the greater of (1) the floating LIBOR rate plus 275 basis points and (2) 3.0%. In November 2012, M/I Financial entered into the MIF Mortgage Repurchase Facility, an additional mortgage financing agreement structured as a mortgage repurchase facility with a maximum borrowing availability of $15.0 million, to provide the Company with additional financing capacity. The MIF Mortgage Repurchase Facility, as amended on November 6, 2013, has an expiration date of November 5, 2014 and is used to finance eligible residential mortgage loans originated by M/I Financial. 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 275 or 300 basis points depending on the loan type. M/I Financial expects to enter into another amendment to the MIF Mortgage Repurchase Facility prior to its expiration that would extend its term for an additional year, but M/I Financial cannot provide any assurances that it will be able to obtain such an extension. At September 30, 2014 M/I Financial's total combined maximum borrowing availability under the two credit facilities was $125.0 million, an increase from $115.0 million at December 31, 2013.

The 2018 Senior Notes are effectively subordinated to our existing and future secured indebtedness with respect to any assets comprising security or collateral for such indebtedness. The 2018 Senior Notes contain certain covenants, as more fully described and defined in the indenture, 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 2018 Senior Notes. As of September 30, 2014, the Company was in compliance with all terms, conditions, and covenants under the indenture. The 2018 Senior Notes are fully and unconditionally guaranteed on a senior unsecured basis by all of our 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 11), 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 2018 Senior Notes.

The “restricted payments basket” is equal to $40 million (1) plus 50% of our aggregate consolidated net income (or minus 100% of our aggregate consolidated net loss) since October 1, 2010, excluding the income or loss from Unrestricted Subsidiaries, plus (2) 100% of the net cash proceeds from the sale of qualified equity interests, plus other items and subject to other exceptions. The restricted payments basket was $145.7 million at September 30, 2014.

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.
