Michigan Compiled Laws, Chapter 445. Trade and Commerce § 445.1635

Sec. 5. A mortgage loan with a term of less than 5 years shall not have a payment schedule with regular periodic payments that when aggregated do not fully amortize the outstanding principal balance. This section does not apply to loans with maturities of less than 1 year, if the purpose of the loan is a “bridge” loan connected with the acquisition or construction of a dwelling intended to become the borrower's principal dwelling.
