Answer ALL questions. You have 90 minutes to finish it. Show ALL your workings clearly. Question 1 ( 16 marks) Sam plans to apply for a fully amortized mortgage loan ( 10 million) of 20 years that charges 5% fixed mortgage rate. a) What is the monthly mortgage payment? ( 4 marks) b) What is the percentage of the first payment that is used to pay principal? Do you think it is "fair" to Sam to have this low percentage of the first payment for paying principal? (4 marks) c) Suppose Sam fully pays off the mortgage loan right after he has made repayments for 8 years. Compute the loan balance using both PV and FV methods. ( 8 marks) Question 2 (14 marks) a) Suppose you want to borrow $20 million from Bank A for a commercial property and you can make two balloon payments of $2 million each in the 60 th and 120 th months.
