Total Interest Paid • 30 vs. 15 year loans • Paying a Mortgage off early. What is saved? • Points and Rates: • 1 point = 1% of loan. • Effect of “points” on effective rate.
Sample of Mortgage Rates, Mar. 2001 Interest RatePoints 7.13% 0.375 6.88% 1.375 6.63% 2.500
Effect of Paying Points Suppose: 6.63% + 2.5 points Loan Amt = $100,000 Pmt = 640.64 What is the effective rate? PV = 100,000 – 2.5% = 97,500 PMT = 640.64 FV = 0, N = 360, I = .5731 * 12 = 6.88%
Suppose Loan is Paid off in 3 years? What is the effective rate? PV = 100,000 – 2.5% = 97,500 PMT = 640.64 FV = 96,499.99 N = 36 I = .6316 * 12 = 7.58%
