Yes, most servicers allow recasting a jumbo loan, but the option is never guaranteed and the rules vary lender by lender. A recast lets you make a large lump-sum payment toward principal, after which your servicer recalculates the monthly payment on the smaller balance while keeping your interest rate and remaining term intact. Because jumbo loans exceed the 2026 conforming limit of $832,750 and sit in private bank portfolios rather than with Fannie Mae or Freddie Mac, each lender writes its own recast policy, minimum payment threshold, and fee.1FHFA.

How a Jumbo Recast Actually Works
A recast is not a new loan. Your rate stays the same. Your term stays the same. There is no credit check and no appraisal. What changes is the monthly payment, because the servicer re-amortizes the reduced balance over whatever months remain on your original schedule.
The math is straightforward. Say you owe $800,000 on a 30-year jumbo at 5.5% with 25 years left. Your principal and interest payment is roughly $4,895. Put $150,000 toward the balance and recast, and the servicer recalculates payments on the new $650,000 balance over those same 25 years. The new payment lands around $3,978. That’s about $917 less each month, with no change to your rate and no reset of the clock. Because every future payment now accrues interest on a smaller balance, the total interest paid over the remaining life of the loan drops as well.
Why Jumbo Recast Rules Vary
Jumbo loans are non-conforming because they exceed the annual limit set by the Federal Housing Finance Agency. Any mortgage above that threshold cannot be sold to Fannie Mae or Freddie Mac.2FHFA. FHFA Conforming Loan Limit Values Conforming loans follow standardized servicing guidelines; Fannie Mae, for instance, defines a recast as a substantial principal curtailment followed by a recalculated payment over the remaining term.3Fannie Mae. Loan Delivery: Re-amortized (Recast) Mortgages Jumbo loans have no equivalent rulebook. Portfolio lenders and specialized investors write their own internal guidelines, so two borrowers with nearly identical jumbo loans at different banks can face completely different answers.
One boundary worth naming: government-backed FHA, VA, and USDA loans cannot be recast at all. That is a structural limitation of those programs. Jumbo loans are conventional by definition, so this exclusion doesn’t apply to them, but it matters if you’re weighing options across more than one property.
Eligibility Factors Your Servicer Will Check
Criteria vary, but jumbo lenders that permit recasts generally look at the same handful of things.
- Current account standing, typically with no missed payments in the prior 12 months. A single late payment in that window can disqualify you.
- A minimum lump sum. Conforming recasts sometimes accept as little as $5,000 to $10,000; jumbo servicers commonly require $10,000 to $50,000 or more, depending on the loan size.
- A seasoning period. Many lenders require the loan to be a few months to a year old before they’ll consider a request, which prevents recasting immediately after closing.
- No prior hardship modification. If your loan was already modified under forbearance or a hardship program, most servicers won’t approve a standard recast on top of it.
What lenders don’t ask for: income documents, a new credit pull, or a fresh appraisal. The original underwriting stands because the fundamental loan terms aren’t changing. The review focuses on payment history and the size of the lump sum.
Fees and Paperwork
Recast fees are modest. Most servicers charge a flat administrative fee somewhere in the range of $150 to $500 to process the recalculation. Compare that to jumbo refinance closing costs of 2% to 6% of the balance. On a $900,000 loan, that’s $18,000 to $54,000 for a refinance versus a few hundred dollars for a recast.
You’ll fill out a recast request form, sometimes called an amortization change request. Expect to provide:
- Proof of funds, usually recent bank or brokerage statements showing the lump sum is available.
- Payment instructions indicating whether the lump sum has already been applied to principal or is being submitted with the request.
- A preferred effective date for the new payment, though the servicer controls the final timeline.
- The administrative fee, which some institutions require as a separate check or wire rather than bundled with the principal payment.
Step-by-Step Process
Once your servicer confirms you’re eligible and you’ve gathered documents, the process moves faster than any other kind of mortgage change. You submit the completed request package through the secure portal or by certified mail, along with the lump-sum payment and the fee. The servicer verifies the funds have cleared and reviews the request. If approved, they send a recast or modification agreement for your signature that records the new principal balance and recalculated payment. Fannie Mae publishes a standardized version of this form, and many portfolio servicers use something similar.4Fannie Mae. Agreement for Modification, Re-Amortization, or Extension of a Mortgage – Fannie Mae Form 181 Some servicers still require notarization; many now accept electronic signatures.
The updated payment schedule typically takes effect within one to two billing cycles after the signed agreement is processed. That lag matters. Until the lower amount appears on your statement, you must keep paying the original amount in full. Cutting the check early because you know the recast is coming is a fast way to trigger a late payment on the account.
Recast vs. Refinance
Both options can lower your monthly payment, but they work differently and the right choice depends on your goal.
A recast keeps the existing loan intact. Same rate, same lender, same term. The payment drops because the balance is smaller. A refinance replaces the mortgage entirely, potentially at a new rate, a new term, and with a new lender. It’s a full origination: appraisal, credit check, income verification, title insurance, and closing costs of roughly 3% to 6% of the balance.5Freddie Mac. Understanding the Costs of Refinancing
For jumbo borrowers the cost gap is enormous. A recast on a $1 million jumbo runs a few hundred dollars; refinancing the same loan can cost $20,000 to $60,000 in closing costs. If you locked in a competitive rate during a low-rate period and current rates are higher, recasting is almost always the better move because refinancing would trade you into a worse rate just to reduce the payment.
Refinancing makes sense when current rates are meaningfully lower than yours, when you want to switch from an adjustable to a fixed rate, or when you need to pull cash out. It also lets you reset the term. A recast doesn’t. If you have 22 years left and want a fresh 30-year schedule to stretch payments further, only a refinance gets you there.
Credit and Tax Effects
A recast doesn’t create a new loan, so it doesn’t touch your credit score. No hard inquiry, no new tradeline. The existing mortgage keeps reporting as usual. That’s a real advantage over refinancing, which pulls credit and closes one tradeline while opening another.
Don’t confuse a voluntary recast with a hardship loan modification. A modification negotiated during financial trouble can be reported to bureaus as a settlement or modified account, which hurts your score. A recast on a performing loan carries none of that.
On taxes, the mortgage interest deduction limit for loans originated after December 15, 2017, is $750,000 of mortgage debt ($375,000 if married filing separately), and that cap was made permanent starting in 2026.6Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction Because most jumbo balances exceed this threshold, you may already be deducting less interest than you actually pay. A recast that brings the balance closer to or below $750,000 can improve your tax efficiency by making a larger share of the interest you pay deductible. Even if the balance stays above the cap, the recast still cuts total interest paid over the life of the loan.
One thing a recast doesn’t change: the original loan date. A recast preserves the loan you already have, so the origination date used for tax purposes carries forward.
When Recasting Makes Sense
Recasting works best in a few specific situations. If you’ve sold a previous home and are holding a large chunk of equity, applying it to your jumbo balance and recasting can meaningfully cut the monthly obligation without the cost or paperwork of a refinance. The same logic applies to an inheritance, a bonus, or proceeds from selling a business or investment.
It also fits when rates have risen since you took out the loan. Refinancing in a higher-rate environment defeats the purpose; recasting preserves your locked-in rate while still lowering the payment. That is the scenario driving most current recast interest, since many borrowers who secured low rates in 2020 and 2021 have no desire to give them up.
Recasting is less useful when your goal is to pay the loan off faster rather than reduce the monthly payment. A lump-sum principal payment without a recast does that on its own, because the same monthly payment retires a smaller balance more quickly. Recasting takes the reduced balance and spreads it over the same remaining term, which lowers what you owe each month but keeps you paying for the full stretch. If cash flow isn’t the issue and early payoff is the point, skip the recast and just make the extra principal payment.
