A. Suppose you have taken out a $125,000 fully-amortizing fixed rate mortgage loan that has a term of 15 years and an interest rate of 6%. After your first mortgage payment, how much of the original loan balance is remaining?

B. Assume you have taken out a partially amortizing loan for $325,000 that has a term of 7 years, but amortizes over 30 years. Calculate the balloon payment at maturity (Year 7) if the interest rate on this loan is 4.5%.

C. Let's assume that you have just taken out a mortgage loan for $200,000 with an origination fee of 2 points due upfront. The mortgage term is 30 years and the mortgage rate is fixed at 4%. What is the cost of the origination fee in dollar terms?
