You have decided to purchase a house in livable, lovable Lodi that is priced at $360,000. You decided to punch 80,000 as a down payment and borrow $280,000 from the bank. The mortgage loan officer at the bank provided you with several mortgage options which you want to evaluate very carefully. The options are (i) 30-year, conventional, fixed rate mortgage (FRM) at 4.8% per year with no discount point, (ii) 15 year, conventional 4.2% per year with no discount point, (iii) 30 year, conventional, fixed rate mortgage at 4.5% with 1 discount point, and (iv) biweekly mortgage at 4.8% per year (under this option, mortgage payment will be exactly one-half of the monthly payment associated with the 30 year FRM at 4.8% per year.)

(b) How long (in years) would it take for you to pay off the to $280,000 mortgage if you wish to make payments biweekly in accordance with option (iv)?

(c) Assume you will choose option (i). If you wish to pay an additional $200 per month, how long would it take for you to pay off the $280,000 mortgage?
