Your cousin can afford a monthly house payment of $675 if her bank is offering financing of 5.2% compounded monthly, on a 30 yr conventional loan, how much money can she afford to borrow for the purchase of a home?
payment = 675
i = .052/12 = .00433333
n = 12x30 = 360
present value = pay (1- (1+i)^-n)/i
= 675( 1 - 1.00433333^-360)/.00433333 = $122,926.00
