[pic] 12.1 1. The terminationic mortgage would be such that the present respect of the mortgage inwardness is equal to the bestowword amount. To find the periodical mortgage amount, we use the PV of annuity formula since periodical wages is the annuity and the PV is the loan amount. The PV of annuity is stipulation as PV = PMT [(1 - (1 / (1 + i)^n)) / i] Where PV = loan amount PMT = monthly mortgage payment i = monthly interest rate n = monthly periods Using the preceding(prenominal) formula we calculate the monthly payments for the given rates and loan amount and time period a. 6.25%, 15 year, $150,000 150,000 = PMT [(1-(1/(1+6.25%/12)^(15X12))/6.25%/12] PMT = $1,286.13 come amount paid = 1,286.13 X 15 years X 12 months = 231,503.40 Loan amount = $150,000 Interest paid = 231,503.40-150,000 = $81,503.4 b. 6.25%, 15 years, 175,000 175,000 = PMT [(1-(1/(1+6.25%/12)^(15X12))/6.25%/12] PMT = $1,500.49 immix amount paid = 1,500.49 X 15 x 12 =270,088.20 Loan amount = 175,000 Interest paid = 270,088.20 175,000 = 95,088.20 Doing the comparable route we are able to fill the table Monthly stipend is | |6.25% |6.50% |7% | |Amount |15 |20 |30 | | 150,000 |$1,286.13 |$1,118.36 |$997.95 | | 175,000 |$1,500.49 |$1,304.75 |$1,164.28 | | 200,000 |$1,714.85 |$1,491.15 |$1,330.
