A balloon payment is a large one-time amount due at the end of a loan. Mortgages, auto loans, and business loans have been structured for balloon payments.Lender shall provide Borrower with a final written statement of monies due prior to the due date of the balloon payment. A balloon payment, simply put, is a large payment that is due at the end of a loan term. It is different from a fully amortized loan, where a loan is paid. A balloon mortgage comes with an unusual twist. Balloon loans have relatively low monthly payments temporarily. But eventually, you make a large "balloon" payment. A balloon payment reduces the number of regular payments borrowers have to make during the life of the loan, making it more manageable financially.
