A balloon payment on a mortgage is considered risky because the borrower will:

A balloon payment typically occurs in loans with shorter terms, not longer ones. The structure of such loans is designed to allow lower payments early on, culminating in a large payment at the end. Therefore, the idea of a longer loan term does not relate to the specific risk associated with balloon payments.

While it is possible that balloon loans could lead to higher overall interest costs due to their structure, the primary risk factor is not about the total interest paid but rather the sudden large payment required at the end. Thus, this choice does not adequately address the nature of the risk involved with balloon payments.

Balloon loans generally feature lower monthly payments during the term leading up to the balloon payment. The risk stems from the fact that, although monthly payments may be manageable, the borrower will face a significantly larger payment at the end, which can be a financial shock.
