U.S. MORTGAGE GUIDE
Should you make a lump-sum mortgage payment?
A bonus, tax refund or sale of an asset can create an opportunity to reduce mortgage principal in one step. Paying earlier usually leaves less principal generating future interest, but a lump sum also reduces your available cash.
Start with the balance, not the original loan
Use the balance currently outstanding and the number of payments already made. A payoff calculator can estimate how much interest remains under the original schedule and what changes after the proposed payment.
Protect liquidity first
Keep an emergency reserve and consider higher-cost debt before committing cash to a mortgage. A mortgage payment normally cannot be withdrawn later without selling, refinancing or using another borrowing option.
Ask whether a partial prepayment has a fee, a notice requirement or a limit, and request written instructions for applying it to principal.
