Analyzing Buydown Rate Loans

A 15-year buydown rate loan is another alternative to finance the $100,000 investment. The nominal annual interest rate is
6.5% initially and will increase to 8% and 9% as of the 24th and 48th payment periods, respectively. The nominal annual interest
rate is lower than that of the fixed rate alternative, at the cost of a 1% discount point ($1000) paid at the initialization
of the loan. The following BUYDOWN statement represents this loan alternative:
