2. Marty and Wendy Byrde have decided to purchase a new home in the beautiful Ozark mountains in Missouri. The cost of the home is $360,000 and the twenty- year loan requires a 20% down payment. The mortgage company offers the Byrde's a variable rate mortgage at a nominal 3% interest rate for the first five years of the loan, 4% nominal interest rate for years six through ten, and 6% nominal interest rate for the remaining years. Assume interest is compounded monthly. a. Compute the monthly payment that Marty and Wendy will have to pay for the first five years of the loan, the monthly payment for years six through ten and for the years eleven through twenty. b. Develop a Present Worth equation that you would use to compute the effective monthly interest rate being charged over the twenty-year period. Show the equations used to compute the nominal interest rate and the effective annual interest rate per year for the variable rate mortgage. C. Compute the effective monthly interest rate being charged over the twenty- year period. Compute the nominal interest rate. Compute the effective interest rate per year for the variable rate mortgage. You may use Excel to compute these interest rates. Submit you Excel file to the Canvas course page. 2.
