Your cousin has decided to take out a mortgage. The cost of the house is $225,000 and a 20% down payment will be made. The fixed interest rate is 7.5% APR on this 30-year old mortgage. The mortgage has a return of 6 years and your cousin plans to make monthly payments.

1. What is the monthly payment on the mortgage

I = 7.5 n= 30x12=360 PV = -225,000 x (1-0.20) = 180,000 FV = 0 P/Y = 12 C/Y = 2

PMT = ? = $1236.88

2. What is the outstanding balance on the mortgage after the 6-year term?

3. How much interest will your cousin pay over the life of the mortgage?
