Refer to the following for Exercises 27 and 28. When interest rates drop, it may become attractive to refinance your home. Refinancing means that you acquire a new mortgage to borrow the current principal due on your home and use the proceeds to pay off your old mortgage. You then begin a new 15- or 30-year mortgage at the new, lower interest rate. A second factor that reduces your monthly payment is that the equity you accumulated under the old mortgage reduces the amount that you have to borrow under the new mortgage. Suppose that you have been paying for 5 years on a 30-year mortgage for $200,000 with a fixed rate of 6%. Your monthly payment is $1199.10, and you have $13,890.81 in equity, so remains to be paid. We consider two refinancing offers.
27. The first offer is from a local bank for a 30-year, fixed-rate mortgage at 4.25% with closing costs of $2639.07. (You must pay the closing costs right away— you cannot include them in the mortgage.)
