A mortgage recast is a straightforward way to lower your monthly payment without refinancing. You make a lump-sum payment toward your principal balance, and your lender recalculates your payments based on the new, lower balance. Your interest rate and loan term stay exactly the same. Only your payment drops.
Recasting appeals to homeowners who have locked in a low rate they do not want to give up, but who have come into extra cash and want to reduce their monthly obligation. It is faster and cheaper than a refinance, and it does not require a credit check or an appraisal.
This guide covers how a recast works, what it costs, which loans qualify, how to compare it against refinancing, and the one important limitation most homeowners do not learn about until it is too late.
How Does a Mortgage Recast Work?
The mechanics are simple. You make a lump-sum payment toward principal, your servicer re-amortizes the remaining balance over the remaining loan term, and you start making lower payments. Here is the process step by step:
- Make the lump-sum payment. You send a payment directly toward your principal balance. Most lenders require a minimum of $5,000 to $10,000, or a set percentage of the remaining balance.
- Your lender recalculates. Once the payment is applied, your servicer recalculates monthly payments based on the new balance using your original rate and remaining term. Nothing else about the loan changes.
- Pay the processing fee. Recasting fees typically run $200 to $500, depending on the servicer. This is the full cost of the process.
Recast Example
Say you have a $500,000 mortgage at 3.5% with 25 years remaining. Your current payment is $2,502/month. You sell an investment property and put $150,000 toward your principal.
Without a recast, your balance drops to $350,000, but your payment stays at $2,502, and you pay off the loan faster.
With a recast, your servicer recalculates based on the $350,000 balance over the remaining 25 years at 3.5%. Your new payment drops to approximately $1,751/month, a reduction of roughly $750. You keep your low rate and free up cash flow every month.
When Should You Consider Recasting Your Mortgage?
- You sold a previous home. Proceeds from a home sale are one of the most common sources of recast funds. Applying the net proceeds lowers your payment on the new home while preserving whatever rate you locked in.
- You received a financial windfall. An inheritance, bonus, or other large cash event can be deployed strategically through a recast rather than sitting idle or going toward lower-yield savings.
- You are happy with your current rate. If your rate is below today’s rates, refinancing would cost you. A recast lets you lower the payment without touching the rate.
- You plan to stay in the home long-term. The lower payment compounds over time. The longer you stay, the more cash flow benefit you realize.
- You want to avoid refinancing costs. Refinancing typically costs 2 to 5% of the loan amount. A recast costs a flat $200 to $500.
One thing worth thinking through before you recast: the lump sum you apply to principal becomes tied up in home equity. Make sure you have adequate cash reserves after the payment. Liquidity matters.
Recast vs. Refinancing: How to Choose
Recasting and refinancing solve different problems. Recasting is the right tool when you want to lower your payment while keeping your loan structure intact. Refinancing makes more sense when you want to change your rate, term, or loan type, or when you need to pull equity out.
| Recasting | Refinancing | |
|---|---|---|
| Process | Lump-sum payment toward principal; lender recalculates payments | New loan replaces existing one; changes rate or term |
| Cost | $200 to $500 flat fee | 2 to 5% of loan amount in closing costs (or $0 for no-cost refi) |
| Rate Impact | No change, keeps your existing rate | Replaces your rate with today’s rate |
| Loan Term | Unchanged | Can shorten or extend |
| Eligible Loans | Conventional only (not FHA, VA, USDA) | Most loan types |
| Credit Check | None | Required |
| Best For | Homeowners with a low rate who want lower payments without touching the loan | Homeowners who can lower their rate or need to change loan terms |
The most common scenario in which recasting wins is when you locked in a rate below 4% and have cash available. Refinancing at today’s rates would raise your rate and your payment. A recast drops the payment without touching the rate.
The most common scenario in which refinancing wins is when rates have dropped since you closed, or your financial situation has changed enough that a new loan on better terms is worth the closing costs.
If a refinance is the better fit, see our guide to a debt consolidation refinance.
Quick Decision Guide
| Choose a Recast If... | Choose a Refinance If... |
|---|---|
| Your rate is below today’s rates | Today’s rates are near or below your current rate |
| You have $10,000 to $200,000+ to put toward principal | You want to change your loan term |
| You want a fast, low-cost process | You want to access equity (cash-out) |
| You have a conventional loan | You have an FHA or VA loan (not eligible for recast) |
| You’re using proceeds from a home sale | You want to consolidate debt into your mortgage |
Advantages of Recasting a Mortgage
- Lower monthly payment. The direct result of the reduced principal balance.
- No rate change. Your existing rate stays in place, which matters if rates have risen since you closed.
- Less interest over the life of the loan. A lower principal balance means less interest accrues over the remaining term.
- Minimal cost. A flat fee of $200 to $500 versus thousands in refinancing closing costs.
- No credit check or appraisal. The process does not touch your credit or require a property valuation.
Disadvantages of Recasting a Mortgage
- Conventional loans only. FHA, VA, and USDA loans are not eligible. Jumbo loan eligibility depends on the servicer and investor who holds the loan.
- No term reduction. Recasting does not shorten your loan term. Your payoff date stays the same unless you continue making extra payments voluntarily.
- Large cash requirement. You need a meaningful lump sum upfront. For homeowners without that cash available, recasting is not an option.
- Equity becomes less liquid. Once you apply a large payment to principal, those funds are tied up in home equity. Accessing them later requires a HELOC, home equity loan, or cash-out refinance.
- No guarantee from your lender. This is the most overlooked limitation. Even if a lender tells you a recast is possible, they cannot guarantee it. Servicing rights are frequently sold after a loan closes, and the new servicer may not offer recasting. Some investors who purchase loans on the secondary market also prohibit it. You need to confirm recast eligibility directly with your current servicer before making any plans around it. See also why a recast is never guaranteed.
Which Loans Can Be Recast?
Not every loan qualifies for a recast, and the loan type is the first thing to check. Conventional loans backed by Fannie Mae or Freddie Mac are generally eligible, and fixed-rate conventional loans are the most straightforward. Adjustable-rate loans can sometimes be recast, though many servicers require the next rate adjustment to be at least six months out.
Government-backed loans are the main exception. FHA, VA, and USDA loans cannot be recast, because their servicing rules do not include voluntary re-amortization after a lump-sum paydown. CalHFA loans are also not eligible. Jumbo loans fall in between, where eligibility depends on the servicer and the investor who holds the loan.
Two more conditions apply almost everywhere. Your loan needs to be current, and most servicers allow a recast only once in a 12-month period. Some also set a short waiting window after closing. Confirm the specifics with your servicer before you count on it.

For additional context on principal paydowns, see Fannie Mae principal curtailment rules.
| Loan type | Recast eligible? |
|---|---|
| Conventional (Fannie Mae / Freddie Mac) | Generally yes |
| Conventional ARM | Sometimes (next adjustment often must be 6+ months out) |
| FHA / VA / USDA | No |
| CalHFA | No |
| Jumbo | Varies by servicer and investor |
Recast vs. Paying Extra Principal
A recast is not the only way to put a lump sum toward your loan. You can also make extra principal payments without recasting, and the two produce different results.
When you pay extra principal without a recast, your required monthly payment stays the same. The extra money reduces your balance, so you pay less interest overall and pay off the loan sooner. What you do not get is monthly budget relief, since the payment amount does not change.
A recast works the other way on cash flow. It re-amortizes the balance over your remaining term, which lowers the required monthly payment but keeps your payoff date unchanged. You free up cash every month rather than shortening the loan.
The choice comes down to your goal. Extra principal payments get you to a paid-off home sooner, with no fees and no servicer approval required. A recast allows you to make a lower payment now while keeping your rate, as long as your loan qualifies.
How to Calculate a Mortgage Recast
The formula is straightforward: take your new principal balance after the lump-sum payment, apply your original interest rate and remaining loan term, and calculate the new monthly payment using standard amortization math.
Monthly payment = P x [r(1+r)^n] / [(1+r)^n – 1]
Where P is the new principal balance, r is the monthly interest rate (annual rate divided by 12), and n is the number of remaining payments.
You do not need to work through this by hand. A standard mortgage amortization calculator handles it in seconds. Plug in your post-payment balance, your existing rate, and your remaining term. The result is your estimated new payment.
For the most accurate figure, contact your servicer directly. They will confirm the exact payoff amount and calculate the recast payment after your lump sum is applied.

How to Request a Mortgage Recast
- Confirm eligibility with your servicer. Call or log in to your servicer’s online portal and ask whether your loan is eligible for a recast. Confirm the minimum lump-sum requirement and the fee.
- Verify your loan type. Conventional loans are generally eligible. If you have an FHA, VA, USDA, or CalHFA loan, a recast is not an option.
- Check for early payoff penalty windows. If you pay down your loan by more than a certain percentage (often 20%) within six months of origination, your lender may face early payoff penalties. This is most relevant when using home sale proceeds shortly after closing on a new purchase. Ask your servicer about any restrictions.
- Send the lump-sum payment. Wire or transfer the funds to your servicer with clear instructions that the payment should be applied to principal for the purpose of a recast.
- Pay the recasting fee. Typically $200 to $500. Confirm payment method with your servicer.
- Receive your new payment schedule. The process generally takes 30 to 60 days. Your servicer will send a new amortization schedule reflecting the lower payment.
Frequently Asked Questions
What is recasting a mortgage?
A mortgage recast is the process of making a lump-sum payment toward your principal balance and having your lender recalculate your monthly payments based on the new, lower balance. Your interest rate and loan term stay the same; only your payment changes.
How much do you need to recast a mortgage?
Most lenders require a minimum lump-sum payment of $5,000 to $10,000, though some require a percentage of the remaining balance. The more you pay down, the more your monthly payment drops.
How much does a mortgage recast cost?
Recasting fees typically range from $200 to $500, depending on the servicer. That is significantly less than refinancing closing costs, which can run 2 to 5% of the loan amount.
Which loans are eligible for a mortgage recast?
Conventional loans (Fannie Mae and Freddie Mac) are generally eligible. Government-backed loans including FHA, VA, and USDA are not. Jumbo loan eligibility varies by servicer. CalHFA loans are not currently eligible under existing program rules.
Does recasting a mortgage affect your credit score?
No. A mortgage recast does not involve a credit check or a new loan application, so it has no effect on your credit score.
Is recasting the same as refinancing?
No. Recasting keeps your existing loan intact and only recalculates your payment after a principal paydown. Refinancing replaces your loan entirely with a new one, which changes your rate, term, or both. Recasting is faster, cheaper, and preserves your current interest rate.
Can all lenders recast a mortgage?
Not all servicers offer recasting, and some investors who purchase loans on the secondary market do not allow it. There is no way for a lender to guarantee that a loan will be eligible for a recast later, since servicing rights can be transferred after closing. Contact your servicer directly to confirm eligibility.
Is A Recast Right for You?
A mortgage recast can be a smart move if you have cash available, a rate you want to keep, and a conventional loan. It is one of the most cost-effective ways to lower a monthly payment, and it takes a fraction of the time and paperwork a refinance requires.
The right answer depends on your current rate, your loan type, and whether your servicer allows it. JVM Lending can help you think through the options and run the numbers side by side.
