2.) You plan to purchase a house for \$430,000 and you will make a 20% down payment. You are
evaluating two mortgages a 30-year fixed mortgage at 2.975 and a 15-year fixed mortgage at
2.35%. Your goal is to have a monthly payment that fits within your budget. Which mortgage
will give you the lowest monthly payment? What will that payment be? How much less will this
be than the other monthly payment?
Mortgage amount = \$430,000*0.8 = \$344,000
