  1. Given:
    purchase price = 320,000
    down payment = 8%
    mortgage bought down (to 6%) with 3 points (3%).
    Term, n= 30 years
    rate, i=6% per annum = 6%/12 = 0.005
    compounding frequency = monthly (ASSUMED).

    Solution:
    Down payment = 8% * 320,000 = 25,600
    Loan, P = 320,000 - 25,600 = 294,400
    Cost of 3 points = 3% * 294,400 = 8832 (amount to be paid at closing)

    Monthly payment = Pi(1+i)^(12n)/((1+i)^(12n)-1)
    =294400*0.005*(1.005^(12*30))/(1.005^(12*30)-1)
    =1765.0767
    =1765.08 (to the nearest cent).
