A mortgage recast is a payment recalculation on an existing loan after a large principal reduction, without replacing the original mortgage.
A mortgage recast is a payment recalculation on an existing loan after a large principal reduction, without replacing the original mortgage.
Mortgage recast matters because it gives borrowers one more way to change the monthly payment without doing a full refinance. For the right loan and lender, a large principal payment can be followed by a recalculated scheduled payment on the remaining balance.
It also matters because borrowers often confuse recast with refinance. The difference is important: recast changes the payment calculation within the existing loan, while refinance replaces the old mortgage with a new one.
The term also matters because recast is usually relevant only after a meaningful principal reduction. Borrowers should not expect an ordinary small extra payment to create the same result.
Borrowers encounter recast after closing, once they already have the loan and later make or consider making a large principal reduction.
The term becomes practical when the borrower wants lower required payments but does not want the cost or disruption of a brand-new refinance transaction and is eligible for recast under the lender’s servicing rules.
A homeowner applies a large lump sum to the principal balance and then asks the servicer to recalculate the scheduled payment based on the reduced balance. That recalculation is a mortgage recast.
Mortgage recast differs from Refinance because recast keeps the existing loan in place, while refinance replaces it.
It also differs from Principal Curtailment because curtailment is the extra principal payment itself, while recast is the later recalculation of the required payment that may follow.
It also differs from Amortization. Amortization is the scheduled balance-paydown structure of the loan, while recast is a later servicing adjustment to the scheduled payment after a major principal change.
