At the end of the blended rate period, the monthly payments of principal and interest shall be adjusted to an amount sufficient to repay the loan plus interest on the balance outstanding from time to time at the rate effective after the blended rate period in equal monthly payments over the remaining original amortization period for the loan.(4) If the borrower accepts an offer by a lender to amend a loan as provided in subsection (1), the amendment shall be executed and delivered at or before the sale or transfer, and shall be effective beginning on the date of the sale or transfer. If for reasons other than acts of the lender the amendment is not executed and delivered before the sale or transfer, then upon consummation of a sale or transfer the lender may enforce a due-on-sale clause. If the borrower amends the loan as provided in subsection (1), then upon consummation of the sale or transfer the lender shall not enforce a due-on-sale clause.(5) If a loan contract is amended as contemplated by this section, the mortgage securing the loan shall retain the same lien priority which it had immediately prior to such amendment or extension.(6) Nothing in this act shall be construed to require a lender to extend the term of a residential real property loan.1984, Act 351, Eff. 10/15/1985 ;--Am. 1985, Act 136, Imd.
