House Mortgage

You have just purchased a house and have obtained a 30-year, $200,000 mortgage with an interest rate of 10 percent.

Required:

A. What is your annual payment?

B. Assuming you bought the house on January 1, what is the principal balance after one year? After 10 years?

C. After four years, mortgage rates drop to 8 percent for 30-year fixed-rate mortgages. You still have the old 10 percent mortgage you signed four years ago and you plant to live in the house for another five years. The total cost to refinance the mortgage is $3,000, including legal fees, closing costs, and points. The rate on a five-year CD is 6 percent.
