Your local bank has offered you a 20-year, $100,000 mortgage. The bank is charging 1.5 points, with "processing" costs of $750; both points and processing costs are deducted from the mortgage when it is given. The mortgage carries a 10% annual interest rate and is paid in equal monthly payments. Note that the monthly payments on the mortgage are calculated on full amount of the mortgage (that is, $100,000 ). Do not calculate annual payment since your payment is monthly. ( 12 points) a.
