Mich. Comp. Laws § 125.1432a
With respect to bonds, other than refunding bonds, issued to finance single family homes after November 1, 1989, for the first 60 days following the announcement of a program funded by the proceeds of those bonds, 50% of the proceeds of those bonds available to make loans, as determined by the preliminary information obtained by originating lenders at the time a reservation is submitted, shall be reserved for applicants with gross annual incomes at or below 60% of the statewide median gross income. The authority may, by resolution, waive this requirement. The authority shall advise the house of representatives and senate standing committees with jurisdiction over housing issues 5 days prior to adopting a resolution waiving this requirement. With respect to bonds, other than refunding bonds, issued to finance single family homes after November 1, 1989, not more than 50% of the proceeds of those bonds may be used to finance single family homes for homebuyers who previously have had an ownership interest in a residence. For purposes of this section, a previous ownership interest in a mobile home shall not be considered to be an ownership interest in a residence. The authority may rely on the applicant's affidavit to determine whether or not the applicant has had a prior ownership interest in a residence. The authority shall publicize the programs funded under this section by using all reasonable means available, including, but not limited to, public interest announcements in the media, and announcements to lending institutions, community groups, and real estate organizations. The authority shall submit a report annually to the legislature containing all statistics necessary to indicate its compliance with this section. This section does not apply to bonds issued to refinance single family homes.
