Negative amortization means that your loan balance is increasing instead of decreasing. This happens when payments on a loan are less than the accruing loan interest; the balance owing increases, because the missing interest is added to the balance.

Reverse mortages require no loan repayments - until the homeowner sells or dies - but accrue regular interest. By design, they are negative amortization loans.
