- What it is: A recast is a large one-time principal payment after which your servicer re-amortizes the loan, lowering your monthly payment while keeping the same interest rate and payoff date.
- Who qualifies: Conventional loans backed by Fannie Mae and Freddie Mac generally allow it. FHA, VA, and USDA loans generally do not.
- The cost: Most servicers charge a processing fee of roughly $150 to $500 and require a minimum lump sum, often $5,000 to $10,000. No appraisal, no credit check, no closing costs.
- The honest catch: Recasting only makes sense when a lower monthly payment is the actual goal. It does not lower your rate or shorten your term.
- Best fit: Homeowners with a rate well below today's (around 6.95% for a 30-year as of September 2026) who came into a windfall and want lower fixed costs.
What a mortgage recast actually is
You came into money. A bonus, an inheritance, proceeds from selling another property. You like your current mortgage rate and you do not want to lose it, but you would rather have a smaller payment every month. A recast is built for exactly that situation.
A mortgage recast, also called re-amortization, works in one move: you make a one-time payment toward the loan's principal balance, and the lender then re-amortizes the remaining balance so the monthly payments are lower, but the interest rate and loan term stay the same. Three things do not change: your rate, your remaining term, and your payoff date. Only the payment drops.
The math is not complicated. When you took out your mortgage, the lender spread the full principal and interest across every month in your term. If you suddenly cut the principal by a significant chunk, the monthly amount drops because there is less principal to spread across the remaining months. Nothing about the loan agreement is renegotiated. The servicer just recalculates one number.
The keep-your-rate advantage: If you locked a rate in 2020 or 2021, recasting lets you put a windfall to work without surrendering that rate. This is the same logic behind the mortgage lock-in effect, only here it works in your favor.
How the re-amortization actually happens
Recasting is a servicing function, not a new loan. Nobody checks your credit or orders an appraisal. It is more of an administrative adjustment to your existing mortgage. Here is the sequence for a conventional loan.
You send in a lump sum
The money goes straight to principal. Your balance drops immediately by the full amount.
You request re-amortization
This is a separate request from the payment itself. The servicer will not automatically recast just because you paid extra.
The servicer recalculates
When a borrower requests re-amortization after a substantial principal curtailment, the servicer recalculates the principal and interest payment using the current unpaid balance, the existing interest rate, and the remaining loan term.
Paperwork gets filed
Fannie Mae requires servicers to complete Form 181, the Agreement for Modification, Re-Amortization, or Extension of a Mortgage, and place a copy in the loan servicing file. Your new, lower payment starts on the schedule the servicer confirms.
This option exists on the secondary-market side too. With a November 2021 Selling Guide update, Fannie Mae will purchase a re-amortized (recast) loan after a substantial principal curtailment from the borrower, where the curtailment reduces the balance and produces a lower payment based on re-amortization over the remaining term. The detail that matters to you: the only changes to the original note terms are to reduce the monthly payment due to the principal curtailment and recast. Everything else stays put. You can read the underlying rules in Fannie Mae's recast loan overview and its principal curtailments guidance.

Enter your balance, rate, remaining term, and lump sum. The tool shows your new payment, monthly savings, and interest saved, then compares it against refinancing the same balance at today's rate. Change the refinance rate to whatever a lender actually quotes you.
Recast vs. Refinance Estimator
Estimate for education only. Your servicer's exact figures and any fees will differ.
Notice the default scenario: with a 3.25% rate, refinancing the same balance at 6.95% would raise your payment, not lower it. That is the whole point of recasting when you are sitting on a cheap rate. Flip the numbers, though, and the answer flips too. Play with the refinance field to see where the crossover happens for your loan.

Find a top agentWho qualifies for a mortgage recast
Two things have to line up: your loan type has to allow it, and your servicer has to offer it. Those are not the same thing.
On loan type, conventional loans backed by Fannie Mae and Freddie Mac are the sweet spot. Government-backed loans are generally not. According to current federal rules, FHA, VA, and USDA mortgages are not eligible for recasting. If you have one of those, your realistic paths to a lower payment are a refinance or, in some cases, a loan modification, not a voluntary recast.
On servicer, even a conventional loan is not guaranteed. You contact your loan servicer and ask if they offer recasting. Not every servicer does, so confirm before you get your hopes up. If they do, they will tell you the minimum lump sum and walk you through the process. Recasting is a servicer courtesy, not a legal right, so the first phone call is the whole ballgame.
| Loan type | Recast eligible? | Your alternative |
|---|---|---|
| Conventional (Fannie/Freddie) | Usually yes, if the servicer offers it | Refinance or extra payments |
| FHA | Generally no | Refinance or modification |
| VA | Generally no | Refinance (IRRRL) or extra payments |
| USDA | Generally no | Refinance or extra payments |
| Jumbo / portfolio | Depends entirely on the lender | Ask the servicer directly |
If a chunk of your lump sum would push your loan-to-value ratio down toward 80%, ask a second question on the same call. If your lump sum drops your loan-to-value to 80% or below, you may be able to request cancellation of private mortgage insurance at the same time. Under the Homeowners Protection Act, borrowers on conventional loans can request PMI cancellation at 80% LTV subject to conditions, but these are separate requests, and your servicer will not volunteer the second one. Knowing how much equity you actually have before you call helps you ask for both.
Recast fees and minimums
This is where recasting shines against a refinance. There is no origination charge, no appraisal, no title work. Most lenders want a minimum one-time payment of $5,000 to $10,000 and charge a processing fee that ranges from $150 to $400. Some run a little higher; most want at least $5,000 to $10,000, and the processing fee runs between $150 and $500 at most servicers.
Compare that to refinancing, where closing costs commonly run into the thousands. Recasting is much cheaper than refinancing because there are no closing costs, no appraisal, and no credit check. When your goal is only a lower payment and you are happy with your rate, paying a few hundred dollars instead of a few thousand is the entire case for recasting.
Recast vs. refinance
This is the comparison most people get wrong, because the two tools solve different problems. A refinance replaces your loan and can change your rate and term. A recast keeps your loan and only lowers the payment.
Today's rate environment makes the distinction concrete. The 30-year fixed-rate mortgage averaged 6.95% as of September 17, 2026, up from 6.76% the prior week and 6.26% a year earlier, per Freddie Mac's Primary Mortgage Market Survey. If your existing rate is below that, refinancing would likely raise your rate, so a recast is almost certainly the better move. If your rate is above today's, a refinance might beat a recast even after closing costs. This is the flip side of the classic "marry the house, date the rate" logic.
| Feature | Recast | Refinance |
|---|---|---|
| Changes your rate? | No, rate stays | Yes, new rate |
| Changes your term? | No, same payoff date | Yes, resets the clock |
| Lowers monthly payment? | Yes | Yes, if rate or term help |
| Requires cash upfront? | Yes, a large lump sum | No large lump sum needed |
| Credit check / appraisal? | No | Yes |
| Typical cost | $150-$500 | Thousands in closing costs |
The honest summary from consumer guidance: refinancing may be best if you qualify for a substantially lower interest rate, don't have a lot of cash to put toward the mortgage, or need to change your loan terms. Recasting works best if you want to keep your current terms, including your rate, but want to lower your monthly payment. If a lower rate is your goal, no amount of recasting gets you there. Start with our guide to how mortgage points work if buying down a rate is really what you are after.
Recast vs. just making extra payments
Here is the option most articles skip, and for many people it is the smarter one. You can throw the same lump sum at your principal without recasting at all. The difference is what happens to the payment.
Extra payment, no recast
You apply the lump sum to principal. Your monthly payment stays exactly the same, but because the balance is lower, you pay off the loan years early and save the most total interest. Your payoff date moves up.
Recast
You apply the same lump sum, then re-amortize. Your payment drops, your payoff date stays the same, and you save less total interest than the extra-payment route because you re-spread the balance over the full remaining term.
So the real question is whether you want lower payments (recast) or the fastest, cheapest payoff (extra payments with no recast). If cash flow relief is not urgent, unstructured extra payments usually deliver more value for the same money.
Either way, protect your payment. The Consumer Financial Protection Bureau notes that you may be allowed to make extra payments on your mortgage's principal to repay the loan more quickly and with less interest, but you should check whether your loan allows extra payments and make sure they are applied to principal rather than interest. Servicers routinely misapply lump sums to the next month's payment instead of principal, so confirm it on your next statement.
Watch the prepayment penalty: Most loans have none, but check before sending a big lump sum. Per CFPB guidance, a lender can't impose a prepayment penalty after the first three years, and penalties are allowed only on certain qualifying fixed-rate loans.
Weighing a windfall against a move?
Sometimes the smarter play is not paying down the current home at all, but trading up or down. A top agent can run the numbers with you before you commit the cash.
Talk to a local expertWhen recasting is the wrong move
Honesty is the point here. Recasting is a narrow tool. These are the situations where a lump sum belongs somewhere else.
- You have high-interest debt. Credit card balances almost always cost more than a mortgage rate. Clear those first; the guaranteed return is higher.
- Your emergency fund is thin. Money sunk into a recast is illiquid. You cannot get it back out without a refinance or HELOC. Keep a cushion first.
- Your rate is above today's. A refinance may lower both your rate and your payment. Recasting locks you into the higher rate.
- You want to be debt-free fastest. Extra payments without a recast keep your payment the same and retire the loan sooner, saving more interest.
- You plan to sell soon. If you are moving in a year or two, tying up cash in the house buys you very little. Keep it liquid for the next down payment.
If the windfall is an inheritance, weigh recasting against the other things that money could do. Our guide to the great wealth transfer and real estate inheritance walks through the tradeoffs when a lump sum lands.
How to request a recast, step by step
Confirm eligibility
Call your servicer. Ask two things: does this loan allow a recast, and do you offer them? Get the answer before you move any money.
Get the minimum and the fee in writing
Ask for the minimum lump sum, the exact processing fee, and how they want the payment submitted so it is not misapplied.
Submit the lump sum and the recast request together
Make clear the money is a principal curtailment and that you are requesting re-amortization. These are two separate instructions.
Ask about PMI in the same call
If the payment pushes you to 80% LTV or below, request PMI cancellation too. It will not happen automatically.
Verify on your next statement
Confirm the balance dropped by the full amount and that your new payment matches what the servicer quoted. Fix any error immediately.
Make one big money decision at a time
Whether you recast, refinance, or move, a top-performing agent helps you see the full picture before you commit your cash. Matching is free.
Get matched with an agentFrequently asked questions
Does recasting lower my interest rate?
No. A recast keeps your existing rate and term. Your interest rate and loan term stay the same after a recast, so you keep the rate you got when you closed. If a lower rate is your goal, you need a refinance instead.
How much does a recast cost?
Far less than a refinance. The processing fee runs between $150 and $500 at most servicers, with no appraisal, credit check, or closing costs.
What is the minimum lump sum to recast?
It varies by servicer. Most lenders want a minimum one-time payment of $5,000 to $10,000, though some set higher minimums depending on your balance. Confirm the exact figure with your servicer.
Can I recast an FHA, VA, or USDA loan?
Generally no. Under current federal rules, FHA, VA, and USDA mortgages are not eligible for recasting. Conventional loans backed by Fannie Mae and Freddie Mac are the usual candidates, if the servicer offers it.
Is recasting better than making extra payments?
It depends on your goal. Recasting lowers your monthly payment. Extra payments without a recast keep your payment the same but pay the loan off sooner and save more total interest. If you do not need cash-flow relief, extra payments usually win.
Will a recast change my payoff date?
No. The lender recalculates your payment over the rest of your loan term. You keep the same rate and payoff date. The only thing that changes is how much you owe each month.
Does a recast require a credit check or appraisal?
No. Nobody checks your credit or orders an appraisal; it is more of an administrative adjustment to your existing mortgage. That is a big part of why it is so much cheaper than refinancing.
Can I cancel PMI when I recast?
Possibly, if the lump sum brings you to 80% loan-to-value. Under the Homeowners Protection Act, conventional borrowers can request PMI cancellation at 80% LTV subject to conditions, but it is a separate request your servicer will not volunteer. Ask on the same call.
The bottom line
Recasting is a clean, cheap tool for one specific job: turning a windfall into a lower monthly payment without giving up a rate you love. If you locked a low rate and want smaller fixed costs, it is often the smartest option on the table. But it is not magic. It will not cut your rate, it will not shorten your loan, and it saves less total interest than simply throwing the same cash at principal and leaving your payment alone. Before you send the money, be honest about what you actually want: lower payments, faster payoff, or a lower rate. The answer to that question tells you whether to recast, make extra payments, or refinance.
