In this guide

A mortgage recast generally concerns recalculating payments over the remaining schedule after a substantial principal reduction. It is not the same as replacing the mortgage with a new loan. Ask your servicer whether your particular loan permits it before sending sale proceeds with that expectation.

Separate the lump sum from the recast

A principal payment can reduce a balance without automatically reducing the required monthly installment. Fannie Mae's servicing guidance provides an investor-specific re-amortization process following substantial curtailment. That does not establish universal availability, minimum amount, fee or processing time.

Ask how to submit the request, when to send the money and what happens if the request is not approved. Compare the cost and cash reserve left afterward. A large payment can reduce interest exposure while making emergency cash unavailable; a lower required installment is only one part of the decision.

Compare two repayment paths

If a recast is approved, examine the new required payment and remaining term. Also model continuing the old payment voluntarily, if permitted and affordable. The second path can create a different payoff horizon. Confirm that extra amounts are applied as intended and distinguish principal-and-interest changes from escrow amounts that can still vary.

The relevant primary reference is Fannie Mae: additional principal payments — investor-specific rules. Read its scope before applying it to a different lender or loan type.

A hypothetical case to work through

Assume a hypothetical $240,000 remaining balance, 5% contract rate and 240 months left. After a $40,000 principal reduction, the assumed re-amortized payment is about $1,319.91 versus $1,583.89 before, excluding escrow and fees. The $263.98 difference assumes unchanged rate and term and an approved recast; a principal payment alone does not guarantee it.

Practical questions

Does every mortgage allow recasting? No. Ask the servicer about your actual loan.

Is a recast automatically a refinance? No. Compare the processes and documents rather than assuming a new loan is being issued.
