balloon or prepayment, and the desired yield rate, the price of the mortgage may

coincident with, and does not include, the last periodic payment amount.

loan. The interest rate is 5% with 72 payments remaining of $137.17 and a
balloon payment at the end of the sixth year of $2,000. If the lender is willing to
discount the future payments at 9%, how much would the borrower need to prepay
the note
