Consider a 25-year $300,000 5/1 ARM having a 2.5% margin and based on the CMT index. Suppose the interest rate is initially 6% and the value of the CMT is 5.8% five years later. Assume that all interest rates use monthly compounding.

Calculate the monthly payment for the first 5 years, the unpaid balance at the end of 5 years, and the monthly payment for the 6th year.
