What Is a Mortgage Recast?
What is a mortgage recast? It is one of the simplest ways to lower your monthly mortgage payment without giving up a good interest rate, and most homeowners have never heard of it. A mortgage recast, also called re-amortization, happens when you make a large lump sum payment toward your principal and your loan servicer recalculates your monthly payment based on the new, lower balance.
Your interest rate stays exactly the same. Your loan term stays exactly the same. Your payoff date does not move. Only your required monthly payment goes down, because you now owe less money and that smaller balance is spread over the months you have left.
Imagine you bought a home in 2021 with a 3.25 percent rate. Today, rates are much higher, so refinancing would mean trading a great rate for a painful one. A recast lets you keep that low rate and still get breathing room in your monthly budget. That is why it has become so popular again in 2026, when many homeowners are sitting on low rates from 2020 to 2022 and do not want to refinance.
A recast is not a new loan. There is no application like a refinance, no appraisal, no credit check, and no income verification in most cases. You are asking the company that already services your loan to do some math again after you pay down a chunk of principal. For the right borrower, at the right time, it can save hundreds of dollars a month for a fee of only a few hundred dollars.
How Does a Mortgage Recast Work?
A recast has two parts. First, you make a substantial lump sum payment, called a principal curtailment, directly toward your loan balance. Second, your servicer re-amortizes the loan, which means it takes the new balance, keeps your same interest rate, and spreads the payments over the same remaining term.
Here is how the process usually works in practice:
- Check eligibility first. Call your servicer and ask if your loan can be recast, what the minimum lump sum is, and what the fee is. Do this before you move any money.
- Make the lump sum payment. Most servicers require at least $5,000 to $10,000. Some require $10,000 or 10 percent of the balance. The money goes straight to principal, not to interest or future payments.
- Sign the agreement. For conventional loans backed by Fannie Mae, the servicer will usually have you sign a re-amortization agreement, known as Form 181, and keep a copy in your loan file.
- Pay the recast fee. The fee is typically $150 to $500, paid once at the time of the request. That is the whole cost in most cases.
- Get your new payment and schedule. Within 30 to 60 days, you should receive a new amortization schedule with your lower monthly principal and interest payment. Your loan number, rate, and maturity date stay the same.
Your taxes and insurance, which are usually paid through escrow, are separate. A recast changes only the principal and interest part of your payment. If your property taxes or homeowners insurance go up, your total monthly payment can still rise even after a recast. That is worth remembering when you do the math.
A Worked Example With a $400,000 Loan
Numbers make this much clearer than theory. Let us walk through a realistic example. All rates here are examples for illustration, not a quote.
Suppose you have a remaining balance of $400,000, an example fixed rate of 6 percent, and 25 years left on your loan, which is 300 monthly payments. Your monthly principal and interest payment would be about $2,577.
Now suppose you receive a $50,000 bonus, an inheritance, or proceeds from selling another asset, and you put that full $50,000 toward principal and ask for a recast. Your new balance is $350,000. Your rate is still 6 percent. You still have 300 payments left.
Your new monthly principal and interest payment would be about $2,255. That is a saving of about $322 every month, or about $3,864 a year, for as long as you keep the loan.
Over the remaining life of the loan, the total interest saving is also large. Before the recast, you would have paid about $773,100 in total principal and interest over those 300 months. After the recast, you pay the $50,000 lump sum plus about $676,500 in monthly payments, for a total of about $726,500. That is a saving of about $46,600 over the life of the loan, minus the small recast fee. You did not shorten the loan, but you paid far less interest because interest was charged on a smaller balance for 25 years.
A smaller lump sum still helps. If you paid $20,000 instead of $50,000 in the same example, your balance would fall to $380,000 and your payment would fall to about $2,448, a saving of about $129 a month. The bigger the lump sum, the bigger the monthly drop. That is why a recast works best when you have a real windfall, not just an extra $500.
Try the same math with your own numbers before you decide. Ask your servicer for a written estimate of your new payment. A $50,000 payment that only saves you $90 a month may not be worth tying up that cash, while the same payment saving you $300 a month could change your budget completely.
What Does a Mortgage Recast Cost?
A recast is cheap compared with a refinance, and that is the whole point. According to Bankrate’s guide to mortgage recasting, the fee is typically between $150 and $500, with no appraisal or credit check required in most cases.
There is no new loan, so there are no origination fees, title fees, or appraisal fees. Refinance closing costs, by contrast, typically run 2 percent to 6 percent of the new loan amount, which can mean $5,000 to $15,000 on a typical loan. A recast fee of $250 is a different world from that.
The lump sum itself is not a fee. Every dollar of it goes to reduce what you owe. It cannot be returned once it is applied, so be sure you do not need that money for an emergency fund, a roof repair, or another goal in the next year or two. Some servicers charge no fee at all, while others charge up to $500. Always confirm the exact fee in writing before you send the money.
The minimum lump sum also varies. Many servicers ask for $5,000 to $10,000. Some ask for $10,000 or 10 percent of the unpaid balance. A few have no stated minimum. If you have $7,000 to put in and your servicer requires $10,000, you cannot recast yet, even though $7,000 is a lot of money. Check first, then plan.
Who Can Recast a Mortgage?
Not every loan qualifies, and this is where many homeowners get disappointed. Recasting is generally available only on conventional loans, usually those backed by Fannie Mae or Freddie Mac. Government backed loans, including FHA, VA, and USDA loans, typically cannot be recast under current servicing rules. You can still make extra principal payments on those loans, but your required monthly payment will not change.
Other common requirements include:
- Your loan must be current. You cannot recast during forbearance or while you are behind on payments.
- You may need some seasoning. Many servicers want a history of on time payments first, often at least 6 to 12 months after closing.
- Your servicer must offer it. Recasting is a servicer policy, not a borrower right. Some servicers do not offer it at all.
- You may be limited to one recast. Some lenders allow only one recast per loan, or one every 12 months. Ask before you use your one chance on a small lump sum.
The Consumer Financial Protection Bureau explains the regulatory background for mortgage servicing and payment changes in its Regulation Z rules. For a plain English walkthrough of the mechanics, fees, and Fannie Mae and Freddie Mac rules, see this step by step guide to how recasting works.
If you have an FHA or VA loan and you want a lower payment, a refinance is usually the only formal route, even though it costs more. That is frustrating, especially since many FHA and VA borrowers also have low rates they want to keep. It is still worth calling your servicer, because policies can change and some portfolio loans have different rules.
Recast vs Refinance vs Extra Principal Payments
These three options sound similar, but they solve different problems. Picking the wrong one can cost you thousands.
Recast
You keep your loan, rate, and term. You pay a lump sum plus a small fee. Your monthly payment drops. Your payoff date stays the same. Best when your current rate is lower than today’s rates and you have a lump sum you do not need for anything else.
Refinance
You replace your old loan with a brand new loan at today’s rate, with new closing costs and a new term. Best when today’s rate is meaningfully lower than your current rate, usually by at least 0.75 to 1 percentage point, and you plan to stay in the home long enough to recover the closing costs. If you refinance a 3 percent loan into a 6.5 percent loan just to lower the payment by stretching the term, you will pay far more interest over time.
Extra principal payments without a recast
You pay extra toward principal each month or once a year, but your required monthly payment stays the same. You pay off the loan faster and save interest, but you get no monthly cash flow relief. Best when your goal is to be debt free sooner, not to lower your monthly bill. If you want both faster payoff and lower payments, you can recast first, then keep paying extra on top of the new lower payment.

When Does a Recast Make Sense?
A recast makes the most sense in five common situations. First, you have a low rate you want to keep. If your rate is 3 percent or 4 percent and today’s rates are near 7 percent, refinancing would be a costly mistake. A recast protects that rate.
Second, you just received a lump sum. A work bonus, an inheritance, a tax refund, proceeds from selling a car or another property, or a maturing investment can all fund a recast. The key is that the money is truly extra, not money you need for your emergency fund.
Third, your income has dropped or your expenses have risen. A new baby, a job change, a medical bill, or higher property taxes can squeeze a budget. Cutting $250 to $350 a month without refinancing can be the difference between comfort and stress.
Fourth, you bought with a large down payment coming later. Some buyers buy a home, then sell their old home a few months later. They use the sale proceeds to recast the new loan and bring the payment down to the level they originally planned.
Fifth, you want lower payments but you do not want a new loan. Maybe your credit score has dipped, your income is harder to document now, or you simply do not want to go through underwriting again. A recast avoids all of that.
When a Recast Is a Bad Idea
A recast is not always smart. Do not recast if the lump sum would wipe out your emergency fund. A lower mortgage payment does not help if a $5,000 car repair then goes on a credit card at 24 percent interest.
Do not recast if you plan to sell or refinance soon. If you will move in a year, the monthly saving may not add up to much, and that cash might have been more useful for moving costs or your next down payment.
Do not recast if you have higher interest debt. Paying off a credit card at 22 percent or a personal loan at 12 percent usually beats putting money toward a 6 percent mortgage. Do the high interest debt first.
Do not recast if your main goal is to pay off the loan early. A recast does not shorten your term. Extra principal payments, without a recast, do shorten it. If early payoff is the goal, keep the payment the same and add extra principal each month.
Finally, do not recast if a refinance would save you far more. If your current rate is 7.5 percent and you can refinance to 6 percent, the rate saving over 30 years will usually beat the payment saving from a recast. Run both numbers side by side before you choose.
How to Request a Recast, Step by Step
Start by calling the number on your mortgage statement and asking for the recast or re-amortization department. Not every representative handles these requests every day, so be clear about what you want.
Ask for the minimum lump sum, the fee, the timeline, and whether your loan type qualifies. Ask if there is a limit on how many times you can recast. Get the answers in writing by email if you can.
Next, confirm your new payment in writing before you pay. Ask the servicer to show you the estimated new principal and interest payment based on your planned lump sum. Check that the math makes sense for your budget.
Then make the lump sum payment exactly as the servicer instructs, usually by wire or certified funds. Keep proof of payment. Sign and return any agreement promptly, because delays can push your new payment start date back by a month.
After the recast, check your next statement carefully. Confirm the new balance, the new payment amount, and the effective date. Keep paying your old amount until the new amount takes effect, or you could accidentally pay late. If anything looks wrong, call immediately and keep notes of who you spoke to.
Common Mistakes to Avoid
The most common mistake is assuming any extra payment automatically lowers your payment. It does not. A regular extra principal payment lowers your balance and saves interest, but your required payment stays the same until you formally request a recast.
Another mistake is recasting too early with too little money. If your servicer allows only one recast, using it for $6,000 when you expect $40,000 from a home sale in six months wastes the opportunity. Wait if a bigger lump sum is coming soon.
A third mistake is forgetting about escrow. Your total payment includes taxes and insurance. A recast lowers only principal and interest. If taxes rise by $150 a month the same year, your total bill may barely change.
Finally, do not assume your loan qualifies. FHA, VA, and USDA borrowers are often surprised to learn they cannot recast. Always check eligibility before you count on the lower payment in your budget.
Frequently Asked Questions
What is a mortgage recast in simple terms? A mortgage recast is when you pay a large lump sum toward your principal and your servicer recalculates your monthly payment on the new lower balance. Your rate and loan term stay the same, only the payment drops.
How much does it cost to recast a mortgage? Most servicers charge a flat fee of $150 to $500. There is usually no appraisal, credit check, or origination fee, which makes it far cheaper than refinancing.
How much do I need to pay to recast? Most lenders require a minimum lump sum of $5,000 to $10,000. Some require $10,000 or 10 percent of the balance. Your servicer sets the exact minimum.
Does recasting change my interest rate? No. Your interest rate stays exactly the same. That is the main advantage if you already have a low rate, and the main limitation if your rate is high.
Does recasting shorten my loan term? No. A recast keeps the same remaining term and payoff date. It lowers the monthly payment, it does not pay the loan off faster on its own.
Can I recast an FHA or VA loan? Generally no. FHA, VA, and USDA loans typically cannot be recast. Conventional loans backed by Fannie Mae or Freddie Mac are the loans most likely to qualify.
How long does a recast take? Most recasts take 30 to 60 days from request to new payment, depending on how quickly you return the agreement and funds. Some servicers move faster, in 15 to 30 days.
Will a recast hurt my credit score? A recast itself is not a new loan and usually involves no credit check, so it should not hurt your score. Your balance will be lower, which is positive, but the account stays the same.
Can I recast more than once? It depends on your servicer. Many allow only one recast per loan, or one every 12 months. Ask before you recast, so you do not waste your one chance.
Is a recast better than refinancing? It depends on your rate. A recast is usually better if your current rate is below today’s rates. A refinance is usually better if today’s rate is meaningfully lower than your current rate.
Do I still save interest with a recast? Yes. Because interest is charged on a smaller balance for the rest of the loan, you pay less total interest over the life of the loan, even though the term does not change.
Should I recast or just make extra payments? Choose a recast if you need lower monthly payments. Choose extra payments without a recast if you want to pay off the loan faster and keep the same monthly payment. You can also do both, by recasting first and then paying extra each month.
