The Quick Read: To recast a conventional mortgage, you send your servicer a large one-time payment toward principal and ask them to recalculate your monthly payment on the lower balance. Your interest rate and payoff date stay exactly where they were. Only the principal-and-interest portion of your payment drops. It is generally available on conventional loans, but the details are set by your servicer, and it is not a guaranteed right.
Key Takeaways
- A recast lowers your payment. It does not shorten your loan or change your rate.
- Your loan usually needs to be current, and you have to ask for the recast. The lump sum alone does not trigger it.
- No new application, income review or credit review is described in the agency servicing rules. Your servicer sets minimums and fees.
- FHA, VA and USDA loans are generally not eligible.
- A recast does not by itself remove mortgage insurance.
What Does Recasting Actually Do?
A recast re-amortizes your loan. You pay down a chunk of principal, and the servicer recalculates your payment over the remaining term. Fannie Mae’s recast loan overview describes it this way: the principal reduction results in a lower monthly payment, based on re-amortizing the new balance over the remaining term. The only change to the original note terms is that lower payment.
Conventional payment estimate
The starting figures are an example price at the first-time buyer’s minimum down payment. Replace them with yours.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $350,000 price, the first-time buyer’s minimum down payment, a thirty-year term at the current Freddie Mac benchmark, mortgage insurance at the low end of Fannie Mae’s published range, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a conventional loan quote; your rate is set by the lender at lock. The mortgage insurance figure is an editable estimate seeded from Fannie Mae’s published typical range, not a premium quote; the insurer prices the actual premium, and the cancellation month assumes scheduled payments with no extra principal and no change in value. Taxes, insurance and dues are editable estimates; closing costs are not included. Conforming loan limits apply by county. Licensed in sixteen states for consumer mortgages.
Think of it as resetting the schedule. Same rate. Same maturity date. Smaller balance, so a smaller required payment.
The agencies use different words than most borrowers do. Fannie Mae’s guide defines a principal curtailment as funds applied to reduce the unpaid principal balance. Your lump sum is the curtailment. The recast is the re-amortization. When you call your servicer, ask for both: “recast” and “re-amortize after a curtailment.”
If you are still shopping for a home, the same logic shows up before closing. A bigger down payment changes the loan you take out. Lendmire’s conventional loan programs are built around purchase leverage of 97% for qualifying first-time buyers and 95% for standard purchases on a primary residence. A recast is the after-closing version of that choice: you commit more cash to the home and let the payment adjust. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Key Terms Defined
Recast (re-amortization): The servicer recalculates your required principal-and-interest payment on your new, lower balance over the same remaining term.
Principal curtailment: An extra payment applied only to your unpaid principal balance.
Servicer: The company that collects your payments and manages your loan day to day. It may not be the lender you closed with.
Amortization: The schedule that splits each payment between interest and principal so the loan reaches zero on its maturity date.
Escrow: The account your servicer uses to collect and pay property taxes and homeowners insurance.
Form 181: The Fannie Mae agreement servicers use to document a re-amortization.
How a Recast Differs From Extra Payments and a Refinance
Extra payments, a recast and a refinance all use cash or a new loan to change your mortgage. They do different jobs.
| Factor | Extra principal payments | Recast | Refinance |
|---|---|---|---|
| Interest rate | Unchanged | Unchanged | Replaced |
| Monthly P&I | Stays level | Drops | Resets |
| Payoff date | Moves earlier | Unchanged | New term |
| New application | No | Not described in agency rules | Yes |
| Closing costs | None | Servicer terms vary | Yes |
The biggest misconception is that extra payments lower your monthly bill. They do not, not by themselves. On a fixed-rate loan, the required payment stays level and the loan simply pays off sooner. The lower payment comes only from the re-amortization.
So the real question is which result you want. Keep the old payment and finish early, or lower the payment and keep the original timeline. One path builds a shorter loan. The other builds monthly breathing room.
Can Your Loan Be Recast?
Probably, if it is a current, conventional loan. Several factors decide it.
Loan type. Conventional loans are the usual candidates. Servicers broadly report that FHA, VA and USDA loans are not eligible, so this option is generally not available on those loans. If you hold a government-backed loan, ask your servicer, then look at refinance options.
Who owns the loan. Investor guidelines control. Servicers apply Fannie Mae or Freddie Mac rules on loans those agencies own. Ask the servicer, not the original lender.
Servicer policy. This is the biggest swing factor. The agency guides do not set a minimum lump sum, a fee or a waiting period. Your servicer does. Some servicers set a minimum curtailment. Some require a stretch of on-time payments or a gap after closing. Some decline to recast at all.
Payment status. Your account needs to be current. Freddie Mac conditions a payment recalculation on the monthly payments being current. Under Fannie Mae’s servicing rules, extra principal sent on a delinquent loan must first cure the delinquency.
Loan structure. Fixed-rate loans are the simplest. Adjustable-rate and interest-only loans have wrinkles, covered below.
Is a recast a right? Not reliably. Treat a recast as generally available, with servicer-specific terms, and don’t plan around it as guaranteed.
Step by Step: How to Recast With a Lump Sum
1. Call the servicer first. Confirm they offer recasts, who owns your loan, the minimum lump sum, any fee and any waiting period. Ask for the answers in writing.
2. Confirm you are current. If you are behind, fix that first.
3. Send the lump sum and label it. Designate it as a principal curtailment, not a regular payment. Timing matters. Under Fannie Mae’s payment processing rules, if the lump sum arrives with your scheduled payment, the monthly payment is applied first and then the curtailment. If it arrives separately, the curtailment is applied first.
4. Request the re-amortization. A curtailment alone does not trigger it. Without a recast request, your payment typically stays level while the loan pays off sooner.
5. The servicer prepares the paperwork. For Fannie Mae loans, that is Form 181. The servicer reports the new payment before the effective date. Freddie Mac lets the servicer decide whether to require a modification agreement, signed by both parties or by the servicer alone.
6. Confirm the new payment. On the effective date, check the new amount in writing and update your autopay.
One sequencing tip: get eligibility confirmed before wiring a large amount. If the servicer declines the recast, your cash has already gone to principal. It still reduces your balance, but your payment will not change.
What the Lender Looks For (Mostly, Nothing New)
A recast is not a new loan. There is no new application, income review or credit review. The qualification test happened when you closed. Fannie Mae’s condition for a recast loan is that the borrower was fully qualified on the original note amount.
Many servicers describe it the same way: sign the recast agreement, keep the loan in good standing, and no appraisal is needed. That is the borrower-friendly side of a recast. You avoid the file review that comes with a new mortgage, and that matters if your income or credit has changed since closing.
Your servicer’s policy still governs. Treat these as typical, not universal.
Where the Rule Breaks: Edge Cases
Adjustable-rate mortgages. Some servicers allow it once the loan is in its repayment period. Freddie Mac says curtailments on an ARM are applied first to any negative amortization, then to principal. Ask how a recast interacts with your next rate adjustment.
Interest-only loans. Freddie Mac says servicers must recalculate the first fully amortizing payment based on the balance after any partial prepayment received on or before the last interest-only due date. Many retail servicers list interest-only loans as ineligible, so ask directly.
Jumbo and portfolio loans. Eligibility for these depends on the investor and servicer. Some servicers exclude most jumbo loans, while others recast them, so ask your servicer directly whether your loan is reviewed.
Mortgage insurance. A recast lowers your balance but does not by itself end mortgage insurance. You can request cancellation at 80% of the original value with good payment history, no subordinate liens and no decline in value. The servicer must terminate it automatically at 78%. Paying down principal can bring you closer to those marks, but you still have to follow the cancellation process. Freddie Mac also conditions any recalculation on mortgage insurance approval where applicable.
Delinquent loans. The payment cures the delinquency first. No recast until you are current.
Recently closed or transferred loans. Some servicers impose waiting periods after origination or a servicing transfer. These are servicer policies, not agency rules.
Prepayment penalties. They are rare on today’s conventional loans. The CFPB says prepayment penalties do not normally apply to extra principal paid in small chunks, but it is worth double-checking with your lender. A large lump sum is a different case, so read your note and Closing Disclosure.
Second homes and investment properties. Fannie Mae’s recast language does not restrict by occupancy, but servicers may, so ask your servicer whether it allows a recast on a second home or investment property.
Recasts are not loan modifications. Fannie Mae directs servicers not to treat a re-amortization as a modification when judging eligibility for a later one. Form 181 is used for both purposes, which causes confusion.
What Changes in Your Monthly Bill
Only principal and interest fall. Your escrow portion, meaning taxes and insurance, can still rise or fall. A recast does not lower your whole bill if property taxes climb.
Your rate and maturity date stay the same, so your payoff date does not move either. A recast lowers the payment instead of shortening the term.
Here is a way to picture it without dollar figures. Say you owe a balance on a thirty-year loan with a fixed rate, and you put a lump sum equal to about a fifth of that balance toward principal. After the recast, your required principal-and-interest payment falls by roughly that same proportion, because the same schedule now amortizes a smaller balance. The payoff date stays put. If you keep paying the old, higher amount anyway, you pay the loan off early, which is the same as skipping the recast.
Is a Recast Right for You? A Decision Framework
A recast tends to fit when:
- You have a rate you want to keep.
- You received a bonus, inheritance or sale proceeds and want a lower required payment.
- Your income dropped or your budget tightened, and you want flexibility without a new application.
- You would rather not pay refinance closing costs.
Pause when:
- Paying down the loan would drain your emergency reserve. Cash put into your home is hard to get back.
- You carry higher-interest debt that deserves the money first.
- Your loan is government-backed or your servicer does not recast.
- You need a different rate or term. That is a refinance question, because a recast keeps the rate and a refinance replaces it.
The honest tradeoff is liquidity. A lower payment feels good, but you traded flexible cash for home equity. Keep an emergency reserve before you pay down a large amount.

Mistakes to Avoid
- Mislabeling the payment. If it is not designated as a principal curtailment, it may not be applied that way.
- Paying before confirming eligibility. Get the answer first.
- Assuming the payment drops automatically. You have to request the re-amortization.
- Ignoring escrow. Your total payment can still change.
- Assuming mortgage insurance disappears. It follows its own cancellation rules.
- Skipping the written confirmation. Get the new payment and effective date in writing.
What to Ask Your Servicer
1. Do you offer recasts on my loan, and who owns it? 2. What is the minimum lump sum? 3. Is there a fee, and when is it due? 4. Is there a waiting period after closing or a servicing transfer? 5. How should I label the payment? 6. Will you complete Form 181 or an equivalent agreement? 7. When is the effective date, and what will my new payment be? 8. What happens to my escrow and mortgage insurance?
If You Cannot Recast
If your loan is government-backed or your servicer declines, you have other routes. Keep making extra principal payments to shorten the loan. Or look at a refinance, which can change the rate or term. Limited cash-out refinances on a one-unit primary residence go up to 95% loan-to-value, subject to lender guidelines and full file review. A refinance does bring a new application, new closing costs and a Loan Estimate.
Frequently Asked Questions
Does a recast change my interest rate?
No. The rate and maturity date stay the same. Only the principal-and-interest payment is recalculated on the lower balance.
Do I need a credit check or appraisal to recast?
Generally not. The qualification happened when you closed, and the agency servicing provisions describe no new income, credit or appraisal review. Servicers set their own policies, so confirm before you send funds.
How big does the lump sum need to be?
The Fannie Mae and Freddie Mac guides set no minimum. Your servicer does, and so does any fee. Some set a modest floor, others a higher one. Ask for the figure in writing.
Can I recast an FHA or VA loan?
Generally no. Servicers broadly report that government-backed loans are not eligible. Ask yours, then consider a refinance if you want a different payment.
Will a recast remove my mortgage insurance?
Not by itself. Insurance ends through its own process: you can request cancellation at 80% of the original value, subject to good payment history, no subordinate liens and no decline in value, and the servicer must terminate it automatically at 78%.
