What Is a Mortgage Recast? Lower Your Monthly Payment Without Refinancing (2026)

A mortgage recast is a little-known but powerful option that lets you make a large lump-sum payment toward your principal and have your lender recalculate — or reamortize — your monthly payment based on the new, lower balance. Your interest rate stays the same, your loan term stays the same, and there's no refinancing required. The result: a lower monthly payment, immediately.

What Is a Mortgage Recast?

A mortgage recast (also called reamortization) is an agreement with your current mortgage lender to recalculate your monthly payment after you make a substantial lump-sum payment toward the principal. The lender takes your current outstanding principal balance — reduced by your lump sum — and spreads the remaining balance over the original remaining term at the original interest rate. The result is a new, lower monthly payment.

Nothing else changes. Your interest rate is unchanged. Your payoff date is unchanged. You don't submit a new loan application, your credit is not pulled, and you don't pay thousands of dollars in closing costs. You simply pay a small recast fee (typically $150 to $500), make the lump-sum principal payment, and your lender processes the new amortization schedule.

Recasting is not the same as making a regular extra payment. When you make an extra payment to principal without recasting, your loan balance drops but your required monthly payment stays the same — the extra money just shortens your payoff timeline. A recast specifically triggers a formal recalculation of the required monthly payment downward.

How a Mortgage Recast Works

The mechanics are straightforward. Here is the step-by-step sequence:

1. Contact your lender or loan servicer to confirm your loan is eligible for recasting and to learn their minimum lump-sum requirement and recast fee.
2. Make the lump-sum principal payment. This is applied directly to your outstanding principal balance, not to future interest.
3. The lender reamortizes your loan. They take the new (lower) principal balance and calculate what monthly payment — at your existing interest rate — would pay it off over your remaining term.
4. You begin making the new, lower payment starting with the next billing cycle. Some lenders apply the change in the same month; others take one billing cycle to process.

The math is the same math used to calculate any mortgage payment, just with a smaller principal. If you owe $350,000 at 7% with 27 years remaining and you pay $50,000 toward principal, the lender recalculates the payment on $300,000 at 7% over 27 years — and that becomes your new monthly obligation.

Recast vs. Refinance: Key Differences

Homeowners sometimes confuse recasting with refinancing. They accomplish different things in different ways:

The right choice depends on your situation. If rates today are higher than your current rate — a common scenario for homeowners who locked in rates in 2020–2021 — refinancing would increase your rate, making it a poor choice for most. In that environment, a recast is the only way to lower your payment without taking on a worse rate.

Who Benefits Most From a Mortgage Recast?

A recast is particularly well-suited for specific situations where you come into a significant sum of money and want your required monthly payment to reflect your new, lower loan balance:

Sold a previous home: This is the most common recast scenario. You buy a new home before selling your old one, sometimes taking a bridge loan or carrying two mortgages temporarily. When your old home sells and you receive the proceeds, you use them to pay down the new mortgage and recast — locking in the lower payment that reflects your equity from the sale.

Received a large bonus or inheritance: If you receive a windfall — an inheritance, a business sale, stock liquidation, or a large year-end bonus — and want to reduce your housing costs immediately, a recast converts that lump sum into permanent payment relief.

Bought a new home before selling the old one: Similar to the first scenario. Many homeowners in competitive markets need to close on a purchase before their sale is complete. The recast gives them a structured way to right-size their mortgage payment after the dust settles.

Want lower cash flow obligations without losing a favorable rate: If you locked in a 3% mortgage in 2021 and want a lower payment without giving up that rate to refinance at 7%, a recast is your only option.

Recast Requirements: What Lenders Typically Require

Recasting is a servicer-specific option, and not every lender offers it. Before counting on a recast, confirm your lender's policy. Typical requirements include:

• Minimum lump-sum payment: Most conventional lenders require at least $5,000 to $10,000; some require more. The payment must go directly to principal reduction.
• Recast fee: Typically $150 to $500, paid at the time of the recast request.
• Loan type: Conventional loans (both Fannie Mae and Freddie Mac) typically allow recasting. FHA, VA, and USDA loans generally do not. Some jumbo or portfolio loans may allow it at the lender's discretion.
• Current on payments: Your loan must be current (no missed payments) at the time of the recast request.
• Seasoning: Some lenders require the loan to be a minimum of 1–2 payments old before a recast is permitted.

Because recasting is a lender-controlled option rather than a federal program, policies vary widely. Always call your loan servicer (the company you send payments to) to confirm their specific recast policy and fees.

Real Example: $400,000 Loan, $50,000 Lump Sum

Here's a concrete example to show the impact of a recast:

In this example, the $50,000 lump sum generates $366 per month in immediate payment relief — a roughly 14% reduction in the required payment. The recast fee of a few hundred dollars is recovered in less than one month of savings.

Does Recasting Save Interest?

Yes — but how much depends on what you do with the payment savings.

If you keep the original payment: If after recasting, you continue to pay your original $2,661 per month instead of the new required $2,295, the extra $366 per month goes straight to principal. This maximizes interest savings and will pay off your loan noticeably earlier than the recast schedule. This is the most aggressive path.

If you pay only the new lower payment: You still save interest compared to your original amortization because your principal balance is permanently lower — you're accruing interest on a smaller balance every month. However, you save less total interest than if you'd kept the original payment amount, because you're extending the time the remaining balance sits on the books.

Comparison — same lump sum, no recast: If you made the same $50,000 extra payment without recasting and kept making your original $2,661 payment, you would save more total interest and pay off the loan earlier. The recast's value is specifically in reducing the required monthly payment — if payment reduction isn't your goal, you may not need to recast at all.

Which Loan Types Allow Recasting?

Recasting eligibility is determined by your loan type and your specific lender's policies:

• Conventional loans (Fannie Mae / Freddie Mac): Generally eligible for recasting. Both Fannie Mae and Freddie Mac allow servicers to offer reamortization, and most major conventional lenders support it.
• Jumbo loans (portfolio loans): Eligibility depends entirely on the lender — many allow it, some don't. Call your servicer to confirm.
• FHA loans: Not eligible for recasting. FHA's servicing guidelines do not include a reamortization option. If you want to reduce payments on an FHA loan after a large principal paydown, a refinance is required.
• VA loans: Not eligible for recasting. The VA program does not include reamortization. Veterans who want to reduce their payment after paying down principal must refinance, though the VA's Interest Rate Reduction Refinance Loan (IRRRL) provides a streamlined path.
• USDA loans: Not eligible for recasting. Like FHA and VA, USDA servicing guidelines don't support reamortization.

Step-by-Step: How to Request a Recast

If you've confirmed your loan is eligible and you're ready to proceed:

1. Call your loan servicer. Ask specifically whether your loan is eligible for a recast (reamortization). Confirm the minimum lump-sum requirement, the fee, and the processing timeline.
2. Request the recast in writing. Most servicers require a written request — via mail, email, or their online portal. This creates a paper trail and officially initiates the process.
3. Submit your lump-sum payment. This is separate from your regular monthly payment. Wire it or send a certified check as directed by your servicer, clearly labeled as a principal-only payment for recast purposes.
4. Pay the recast fee. Submit this along with or after your principal payment, per your lender's instructions.
5. Receive your new amortization schedule. Your servicer will send you a revised payment schedule showing the new monthly amount and the updated payoff date (which should be unchanged from your original term).
6. Begin making the new payment. Switch your automatic payments or payment method to the new amount, starting with the effective date specified by your servicer.
