If you recently came into a large sum of money — an inheritance, a bonus, the proceeds from selling another property — you may be wondering about the best way to use it to reduce your mortgage burden. Most people immediately think about refinancing. But there is another option that far fewer homeowners know about: mortgage recasting.
Mortgage recasting lets you lower your monthly payment without going through the full refinance process. Here is how it works, who qualifies, and when it actually makes financial sense.
What Is Mortgage Recasting?
Mortgage recasting — also called a loan recast or reamortization — is a process where you make a large lump-sum payment toward your principal balance, and your lender then recalculates your monthly payment based on the new, lower balance. Your interest rate and loan term stay the same. Only your monthly payment drops.
For example, suppose you have a $300,000 mortgage at 6.5% with 25 years remaining. Your monthly principal and interest payment is about $2,023. If you make a $50,000 lump-sum payment, your balance drops to $250,000. After recasting, your lender recalculates your payment on that new balance at the same rate over the same remaining 25 years — and your monthly payment falls to roughly $1,686, saving you about $337 per month.
How the Recasting Process Works
The process is simpler than refinancing. Here is what typically happens:
- Contact your lender. Not all lenders offer recasting. Call your servicer and ask whether your loan is eligible.
- Make the lump-sum payment. Lenders usually require a minimum payment — commonly $5,000 to $10,000, though some require more.
- Pay the recasting fee. Fees are typically $150 to $500, far less than the thousands you might spend on a refinance.
- Lender recalculates your payment. Your lender reamortizes the remaining balance over the remaining loan term at your current interest rate.
- New payment begins. Usually one to two billing cycles after the recast is processed, you begin paying the lower amount.
Recasting vs. Refinancing: The Key Differences
People often confuse recasting and refinancing because both can reduce your monthly mortgage payment. But they work very differently.
- Interest rate: Stays the same in a recast; can change with a refinance
- Loan term: Stays the same in a recast; resets (typically 30 years) with a refinance
- Credit check: Not required for a recast; required for a refinance
- Costs: $150 to $500 for a recast; 2% to 5% of loan amount for a refinance
- Lump sum required: Yes for a recast; no for a refinance
- Timeline: 2 to 4 weeks for a recast; 30 to 60 days for a refinance
Refinancing makes more sense when interest rates have dropped significantly since you took out your mortgage. Recasting makes more sense when your current rate is already competitive and you simply want to lower your monthly obligation using a windfall.
Who Is Mortgage Recasting For?
Mortgage recasting works best for homeowners who:
- Have a conventional mortgage (FHA, VA, and USDA loans are generally not eligible)
- Have received a large lump sum — from an inheritance, home sale, bonus, or investment gains
- Have a competitive interest rate they want to keep
- Want lower monthly payments without resetting their loan term
- Want to avoid the hassle of a full refinance application process
The Benefits of Mortgage Recasting
Lower monthly payment. The most direct benefit. Reducing your monthly payment frees up cash for other priorities — investing, saving, or building an emergency fund.
No credit check required. Your credit score has no impact on whether you qualify for a recast. This is a major advantage if your credit has changed since you took out the mortgage.
Minimal fees. A few hundred dollars versus potentially tens of thousands in refinancing costs.
You keep your interest rate. If you locked in a rate of 3.5% in 2021 and rates are now higher, recasting lets you reduce your monthly payment while keeping that favorable rate intact.
Faster and simpler process. No appraisal, no full application, no waiting for underwriting approval.
The Drawbacks of Mortgage Recasting
You must have a large lump sum. Recasting requires tying up a significant amount of money in home equity — money that could potentially earn more in investments.
Not available on all loan types. Government-backed loans typically cannot be recast. Check with your servicer before assuming you qualify.
Does not change your rate or term. If you are stuck in a high interest rate, recasting will not help you there. Only a refinance can lower your rate.
Opportunity cost. The money you put toward your mortgage is money that is not working for you in the market. Over long time horizons, investing that lump sum in a diversified portfolio may produce a higher return than the interest you save.
How to Request a Mortgage Recast
Start by calling your loan servicer. Ask these questions:
- Is my loan eligible for recasting?
- What is the minimum lump-sum payment required?
- What is the recasting fee?
- How long does the process take?
- Will my loan term stay the same?
Get the details in writing before you submit the payment. Once that money is applied to your principal, the decision is not easily undone.
Bottom Line
Mortgage recasting is a practical, low-cost way to reduce your monthly mortgage payment if you have a lump sum to put toward your principal. It is especially attractive when you have a favorable interest rate you want to keep and want to avoid the cost and hassle of refinancing. Make sure your other financial priorities — debt, savings, investments — are in order first before tying up a large sum in home equity.
