A principal curtailment is an extra payment applied directly to reduce the mortgage principal balance.
A principal curtailment is an extra payment applied directly to reduce the mortgage principal balance.
Principal curtailment matters because borrowers often think the mortgage balance falls only according to the original amortization schedule. In reality, extra principal payments can change how quickly the balance declines.
It also matters because borrowers need to understand the difference between making the ordinary payment and deliberately directing extra money to principal reduction.
Borrowers encounter principal-curtailment decisions after closing, once the loan is in repayment and they are deciding what to do with extra cash.
The term becomes practical when the borrower wants to reduce interest exposure, shorten balance life, or set up a later Mortgage Recast.
A homeowner receives a bonus and sends extra money to the servicer with instructions that it be applied to principal. That extra principal reduction is a principal curtailment.
Principal curtailment differs from Mortgage Recast because curtailment is the extra payment itself, while recast is the later recalculation of the required payment on the existing loan after a major principal reduction.
It also differs from Payoff Statement because a curtailment reduces but does not fully satisfy the mortgage, while a payoff satisfies the loan in full.
