You need a 30-year, fixed rate mortgage to buy a new home for $200,000. Your mortgage bank will lend you the money at a 7.5% APR for this 360-month loan. However, you can only afford monthly payments of $1000, 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 ballon payment have to be for you to keep your monthly payments at $1000?
