Section 528.7 - Reduction in installment payments - repayment of mortgage debt1. If the mortgagee or its assignee and the mortgagor agree, any installment payment of either the loan proceeds or an annuity purchased with the loan proceeds of a reverse annuity mortgage loan may be reduced by an amount used for partial repayment of the mortgage debt, except as provided in subsection 2 of this section. a. Notwithstanding any such reduction, each mortgagor shall receive a cash payment in each installment for the term of the annuity or, if no annuity, for the term during which the mortgagee contracted with the mortgagor to advance the loan proceeds.b. Except as provided in subsection 2, no repayments of any part of the mortgage debt shall be required from the mortgagor after termination of the period during which loan proceeds or any annuity purchased with the loan proceeds are advanced to the mortgagor.2. If the mortgagee or its assignee and the mortgagor agree, and at the option of the mortgagee, advances under a reverse annuity mortgage loan may terminate and the entire unpaid balance of the loan plus accrued interest may become due and payable upon the occurrence of any of the following events: a. The death of the last surviving mortgagor.b. The sale or other transfer of the real estate securing the loan to a person other than any of the original mortgagors.c. Any other occurrence which materially decreases the value of the property securing the loan or which will have the likely effect of causing the loan not to be repaid. Any such additional occurrence shall be clearly described in the note or mortgage instrument.Referred to in §528.2, 528.6
