3 Ann got a 10 year Fixed Rate Mortgage for $100,000. The loan has constant annual payments and an annual interest rate of 5%. The closing cost for the loan is $2,000 (paid at the time of origination, t=0 ). Suppose Ann prepays the loan in year 4. Write the NPV of Ann's Mortgage (from Ann's perspective) for an annual discount rate " k " in each of the following cases. Note: the answer must take the form NPV(k)=CF0+(1+k)1CF1+(1+k)2CF2+(1+k)2CF2+(1+k)4CF0 Note: only include one cash-flow for each time period 3a Fully Amortizing 3b Partially Amortizing where the final balance is B10=$50.000 3c Interest Only 3d Negatively Amortizing where the payment is PMT=$1,000 3e Negatively Amortizing where the payment is PMT=$0
