5. For each scenario, calculate the total cost of the home purchase. (Down payment plus principal (loan amount) plus interest.) Down Payments Total Payments Total costs Scenario 1 $ 120,000 Scenario 2 Scenario 3 6. Assume that you plan to pay an extra $200 per month on top of your mortgage payment, calculate how long it will take you to pay off the loan given the higher payment. (Use the corresponding interest rate in questions 1, 2, and 3). Calculate how much interest you will pay in total? Compare this to the value that you calculated for the 4th question. Periodic Payment PV of Loan Periodic Rate Months Total interests Scenario 1 Scenario 2 Scenario 3 You want to determine whether you should save some of your money and put only 10% down on your house. Because you are only putting 10% down, lenders require that you purchase private mortgage insurance (PMI). Assume that PMI is 1% of the mortgage amount per year. 7. Calculate your total monthly payment (mortgage payment plus PMI). House costs 600000 Down payment 60000 PV of loan (PV) 540000 # of periods (T): 360 Periodic interest rate (r): 0.38% Payment amount (pnt): $2,736.10 PMI PMI Payment per month Total Payment per month 5.
