You need a 15 year, fixed rate mortgage to buy a new home for $80,000. Your mortgage bank will lend you the money at an 8.5% rate for this 180 month loan. However, you can only afford montly payments of $395.00, so you offer to pay off any remaining loan balance at the end of the loan in the form of a single balloon payment. How large will this balloon payment have to be to keep your montly payments at $395.00?
