Consider an MPT that is backed by 100 mortgages with average balance of $350,000 and monthly payments. The MPT has a WAC = 5% and WAM = 60 months. There is no servicing fee on this security. Assuming a prepayment model of CPR=5%(stays constant throughout) and the investors' discount/market rate is 3%, how much should this security sell for (i.e. how much should investors pay for the claims to the payment generated by the mortgage pool)?Remember,if necessary,to adjust rates to monthly.Excel recommended for this problem using NPV function.
