How to Recast Your Mortgage in 5 Steps

RD By RecastDesk editors · Updated October 2026 · 9 min read

A recast is a phone call, one signed form and a wire transfer — and most of the elapsed time belongs to the servicer, not to you. The part people get wrong is the order of operations: they send the money first and ask for the terms second. Do it the other way round and the whole thing takes about three weeks instead of three months, and you never have to argue about what was promised.

The short answer

You need four things: a servicer that offers recasts at all, a lump sum above their minimum principal reduction, a written request with the funds, and the fee. Typical turnaround is two to six weeks from the day the money clears, and a handful of servicers do it in under ten business days.

The single thing that decides whether this goes smoothly is getting the new payment quoted in writing before any money moves. A recast is irreversible in the sense that the principal is gone from your savings the moment it lands, so the quote is your only leverage. Ask for it first, compare it against the calculator on this site, and only then authorise the transfer.

Check you qualify before you call anyone

Recasts are a servicer-level product, not a legal right, so eligibility starts with who services your loan. Several large servicers do not offer them at all, and a few stopped during the refinance boom when their processing capacity was stretched. If yours is one of them, everything below is moot — check the servicer pages first.

Beyond that, the usual conditions are: the loan is current, it is a first lien that amortises, and the principal reduction clears a minimum. Conventional loans are the common case. FHA and VA loans are recastable at some servicers and not at others, because it depends on the investor behind the loan rather than on the programme itself. HELOCs, reverse mortgages and interest-only loans are generally out.

What to have ready before step one

Pull four numbers off your most recent statement: the current principal balance, the rate, the months remaining, and the servicer’s name as it appears in the payment address. You also need the exact lump sum you intend to apply and the fee the servicer charges.

Ask for a principal balance statement rather than a payoff quote. A payoff quote includes interest accrued to a future date and a per-diem, which is the right document when you are closing a sale and the wrong one when you are applying a fixed sum to principal.

Step 1 — Ask for the policy in writing

Use both words when you ask: recast and re-amortization. Front-line representatives are trained on refinancing and frequently do not recognise the first term, which is how people end up being told the product does not exist. If the phone answer is no, ask for it in a secure message before believing it.

Three questions, one message: is a recast available on my loan, what is the minimum principal reduction, and what is the fee and typical processing time? A written answer to those three is your baseline. Anything a representative tells you verbally is not evidence — the dispute, if there is one, happens six weeks later with a different department.

Step 2 — Get the new payment quoted before money moves

Give them the balance, the lump sum and the date you intend to send it. Ask for the new monthly principal and interest, and the date the new payment takes effect. This is the moment to compare against your own arithmetic; a difference of a few dollars is rounding and effective-date interest, but a difference of fifty dollars means something in your assumptions is wrong.

The usual culprits are escrow (unchanged, so the total payment falls less than the principal-and-interest figure), accrued interest to the effective date, and a fee deducted from the lump sum rather than billed separately. Ask explicitly whether the fee comes out of the money you send. If it does, the principal reduction is smaller than you planned and the quoted payment will not match the calculator until you adjust for it.

Step 3 — Send the principal and the request together

Same day, same package: the signed recast request, the funds, and the fee if it is billed separately. Reference the loan number on every document. A payment that arrives before the request is processed as an ordinary principal curtailment — the balance drops, the payment does not, and you have to start over.

Send money only to an address or account that appears on your statement or in the servicer’s authenticated portal. Never to an address read out over the phone, and never in response to an inbound call about your recast. This is a well-known fraud pattern precisely because the amounts are large and the urgency feels real.

Step 4 — Confirm the effective date in writing

Funds clearing is not the same as the recast taking effect. Interest accrues on the old, larger balance until the effective date, which is typically the first billing cycle after the funds post. The cost is the interest the lump sum would have stopped accruing: on $50,000 at 6.5% that is about $8.90 a day, so a four-week delay is roughly $250 — real money, even though nobody itemises it.

Ask for the effective date in the same written channel, then check the first statement after it. If the payment is still the old figure, you are not being paranoid — recasts do get queued and forgotten, and the fix is faster when you can point at a date you were given in writing.

Step 5 — Verify the new statement and the schedule

Four things to check on the first statement after the effective date. The principal balance should equal the old balance minus your lump sum. The payment should match the quote. The remaining term should be unchanged, so the payoff date is exactly where it was. And the amortisation schedule should have been reissued.

If the payoff date moved, that is not a recast — someone has processed a modification or a refinance, and you should stop and get it in writing before making another payment. It is rare, but it is the one error that quietly costs years of interest.

The four mistakes that cost the most

Sending money before the quote. It is the most common and the most expensive, because once the principal is applied you are negotiating from a position of having already paid.

Expecting the rate or the term to change. A recast does neither. People who wanted a lower rate needed a refinance, and people who wanted a shorter loan needed extra principal; discovering this after the fact is a $300 lesson in terminology.

Expecting the payment to fall by the full principal-and-interest difference. Taxes and insurance sit on top and do not move. A recast that cuts $210 of principal and interest on a payment with $480 of escrow reduces the debit by $210, which is a 9% fall, not the 15% people had in mind.

Not asking about the fee’s treatment. Deducted from the lump sum or billed separately changes both the principal reduction and the break-even calculation, and it is a one-line question.

If your servicer will not do it

There are five common reasons for a no: the investor behind the loan does not permit recasts, the loan type is excluded, the lump sum is below the minimum, the account is delinquent, or the loan is interest-only or a balloon. Ask which one applies, because only some of them are fixable.

If it is a hard no, the alternatives are straightforward and none of them do the same job. Extra principal shortens the loan and leaves the payment alone. A refinance can lower the rate but costs thousands and restarts the clock. And servicing transfers are common — if your loan moves to a new servicer, the policy moves with it, so the question is worth re-asking in a year rather than treating the current answer as permanent.

Frequently asked questions

The questions that come up after the first call to a servicer.

Q
How long does a mortgage recast take?
Two to six weeks from the day the funds clear is typical, and a few servicers finish in under ten business days. Almost all of that time is internal processing rather than anything you have to do. Ask for a target effective date when you submit the request — a written date is what makes a slow recast escalateable instead of just slow.
Q
Is the recast fee taken out of the lump sum?
It varies by servicer, and it is worth asking explicitly. If the fee is deducted from the money you send, your principal reduction is smaller than planned and the quoted payment will not match a calculator run that assumed the full sum went to principal. On a $300 fee against a $50,000 lump sum the difference is small, but the quoted payment should still reconcile to the cent.
Q
Can I recast my mortgage more than once?
Sometimes. Many servicers will recast repeatedly as long as each request meets the minimum principal reduction and pays the fee again, but a few limit how often it can be done on the same loan. Ask when you submit the first one so you know whether to hold a second lump sum or combine both into a single request.
Q
Does a recast require a credit check or an appraisal?
Not in the standard process. You are paying down existing debt rather than taking on new credit, so there is no underwriting, no income verification and no valuation of the property. Some servicers run an identity check. If you are asked to complete a full application with income documents, you are being moved toward a refinance, which is a different product with different costs.
Q
My loan was just transferred to a new servicer. Can I still recast?
Yes, but the new servicer’s policy governs, not the old one’s. Recast availability, the minimum principal and the fee all move with servicing, and it is common for a loan to gain or lose the option in a transfer. Wait until the transfer is complete and the first payment has posted with the new servicer before applying, or the request can be lost in the handover.
Q
Can I recast a HELOC or a second mortgage?
Generally no. A recast re-amortises a fully drawn, amortising balance over its remaining term, which is what a first mortgage is. A HELOC is a revolving line during its draw period and second mortgages are often interest-only or balloon structures, so there is nothing for the servicer to re-amortise in the usual sense. Paying a HELOC down lowers the interest you are charged but does not lower a payment that does not exist yet.
