A borrower has the choice between two mortgage loans. Both are to be amortized by monthly payments over 10 years. A mortgage broker will charge a fee of $2200 for an $82,200 face value loan at 10.25% compounded semiannually. A trust company will grant an $80,000 loan (with no other fees) at 10.75% compounded semiannually. Determine which loan has the lower effective annual cost of borrowing if the contractual interest rates are for
a. A 5-year term.
b. The entire 10-year amortization period.
