What characterizes a balloon mortgage?

A balloon mortgage is specifically characterized by a large final payment due at the end of the loan term. This type of mortgage usually involves smaller monthly payments throughout the majority of the loan period, which do not fully amortize the loan. As a result, borrowers face a substantial "balloon" payment at the end which can be significantly larger than the previous payments.

This structure makes balloon mortgages appealing for certain borrowers, particularly those expecting to refinance or sell the property before the balloon payment is due. Understanding this characteristic is crucial for borrowers to consider their financial situation and future plans when entering into such an agreement.

The other choices depict features that do not align with the nature of a balloon mortgage. For example, fixed monthly payments would correspond more closely to a conventional fixed-rate mortgage rather than the unique payment structure of a balloon mortgage. A variable interest rate pertains to adjustable-rate mortgages, and long-term duration extending beyond 30 years is not typical for a balloon mortgage, which often has shorter terms.
