A. Suppose a potential home buyer is interested in taking a $500,000 mortgage loan that has a term of 30 years and a fixed mortgage rate of 5.25%. What is the monthly mortgage payment that the homeowner would need to make if this loan is fully amortizing?

B. You have taken out a $350,000, 3/1 ARM. The initial rate of 6.0% (annual) is locked in for 3 years. Calculate the outstanding balance on the loan after 3 years. The interest rate after the initial lock period is 6.5%. (Note: the term on this 3/1 ARM is 30 years)

C. You have taken out a $300,000, 5/1 ARM. The initial rate of 5.4% (annual) is locked in for 5 years. Calculate the payment after recasting the loan (i.e., after the reset) assuming the interest rate after the initial lock period is 8.0%. (Note: the term on this 5/1 ARM is 30 years)
