As used in this act, "graduated payment mortgage" means a mortgage loan with lower monthly payments of principal and interest during the early years of the mortgage and higher monthly payments during the later years of the mortgage. The graduation rate for the monthly payments, the term of graduation, and the interest rate are fixed throughout the term of the mortgage. Monthly payments of principal and interest are required in amounts sufficient to pay all interest and effect full repayment of principal within the term of the mortgage.
