Mortgage Recast vs. Refinance: When Recasting Saves You Money

Quick answer: A mortgage recast (also called re-amortization) is when you make a large lump-sum payment toward your principal and your servicer recalculates your monthly payment over the remaining term. Your interest rate and payoff date stay the same, and your payment drops. There's no new loan, appraisal or credit check, and usually just a modest servicer fee. Recasting generally beats refinancing when you already have a good rate and extra cash. Refinancing wins when you can get a meaningfully lower rate or need to change your loan. Most conventional loans can be recast if your servicer offers it. FHA, VA and USDA loans generally can't.
Most homeowners know about refinancing. Fewer know about recasting, a simpler way to lower your monthly mortgage payment if you have cash on hand. If you just sold your previous home, received an inheritance or got a big bonus, a recast can meaningfully lower your required payment without giving up a low rate you locked in years ago.
What is a mortgage recast?
A mortgage recast is a recalculation of your loan's payment schedule after you pay down a chunk of principal. Fannie Mae's servicing rules describe it as re-amortizing the loan to reduce the monthly payment after a substantial principal curtailment.
What changes and what doesn't:
- Changes: your required monthly principal-and-interest payment (it goes down)
- Stays the same: your interest rate, your loan term and payoff date, and your lender or servicer
- May still change on its own: the escrow part of your payment (taxes and insurance), which isn't affected by a recast
How a mortgage recast works: an example
Because a recast keeps your rate and your remaining schedule, your new principal-and-interest payment shrinks in proportion to your balance.
Say you owe $400,000 and you sell your old house and put $75,000 toward principal, then ask your servicer to recast:
| Before recast | After $75,000 recast | |
|---|---|---|
| Loan balance | $400,000 | $325,000 |
| Interest rate | Your current rate | Unchanged |
| Payoff date | Your current payoff date | Unchanged |
| Required principal & interest | Your current amount | About 18.75% lower |
The math: $75,000 is 18.75% of $400,000, so the recalculated principal-and-interest payment drops by about the same share. Hypothetical illustration, rounded. Your servicer calculates and confirms the exact new payment, and your escrow for taxes and insurance isn't affected.
Mortgage recast vs. refinance
| Recast | Refinance | |
|---|---|---|
| New loan? | No | Yes |
| Interest rate | Stays the same | Can change |
| Loan term | Stays the same | Can change |
| Lump-sum cash needed? | Yes | No (cash-out is possible) |
| Credit check / income docs | Generally no | Yes |
| Appraisal | No | Often |
| Typical cost | Servicer fee, if any | Freddie Mac says 3%–6% of the loan principal |
| Who you work with | Your current servicer | Any lender (or a broker who shops several) |
| Can remove a co-borrower? | No | Yes |
When recasting wins
- You already have a good rate. If your rate is below what's available today, a refinance means giving it up. A recast keeps it.
- You have a lump sum and want monthly relief. Home sale proceeds, an inheritance, a bonus or a settlement.
- You bought before you sold. If you financed a new home (perhaps with a bridge loan) before your old one sold, a recast can "right-size" the new payment once the sale closes.
- You want to avoid refinancing costs and paperwork. No underwriting, no appraisal, no title work.
When refinancing wins
- Rates have dropped meaningfully. A lower rate can save more over time than a recast, even after closing costs. Here's our take on when to refinance and when not to.
- You don't have a lump sum. Refinancing to a lower rate or longer term can lower your payment without new cash.
- You need to change the loan itself. For example, moving from an adjustable to a fixed rate, taking cash out, or removing a co-signer or ex-spouse. A recast can't change who's on the loan.
- You have an FHA, VA or USDA loan and want a lower payment. These generally can't be recast, so refinancing is usually the main path.
Recast vs. just making extra payments
You can always send a lump sum toward principal without recasting. Here's the difference:
- Extra payment, no recast: Your required payment stays the same, but you pay less interest overall and pay the loan off sooner.
- Extra payment plus recast: Your required payment drops, but your payoff date stays the same. You save some interest (because the balance is lower), though not as much as you would by keeping the old payment.
If cash flow is the goal, recast. If paying off early is the goal, skip the recast and keep paying the original amount. You can still pay extra after a recast whenever you like. For the math on early payoff, see paying off a home early.
Mortgage recast requirements
Rules vary by servicer and investor, but expect these:
- Eligible loan type. Conventional loans are the most common candidates. Fannie Mae's servicing guide spells out how servicers process re-amortization requests. Government loans (FHA, VA, USDA) generally aren't eligible. Chase, for example, states that its FHA, VA and USDA loans can't be recast.
- Servicer participation. No law requires servicers to offer recasts. Ask yours directly.
- Minimum lump sum. Each servicer sets its own minimum, and some don't have one. A small principal payment won't move your payment much, though.
- Good standing. Your loan generally must be current.
- Fee. Many servicers charge a processing fee. Ask for the amount in writing.
- Paperwork. You'll typically sign a recast (re-amortization) agreement that shows the new payment and when it takes effect. Keep making your regular payment until the servicer confirms the change.
Did your loan get sold or transferred? Your recast request goes to whoever services it now. Check your latest statement or transfer notice for the current servicer.
Pros and cons of recasting your mortgage
Pros
- Lower required monthly payment
- Keep your existing interest rate and term
- Usually no credit check, income documentation or appraisal
- Much lower cost than a refinance
- Lowers total interest compared with not prepaying at all
Cons
- Requires a large lump sum, which reduces your cash cushion
- Doesn't lower your rate if rates have dropped
- Not available on most government-backed loans, or from every servicer
- Money put into your home is harder to access later (you'd need to sell, refinance or borrow against it)
- Less interest paid can mean a smaller mortgage interest deduction if you itemize. Ask your tax professional.
Bonus: a lump sum can also help you drop PMI
If you have a conventional loan with private mortgage insurance, the same lump sum that funds a recast may bring your balance close to the point where you can ask to cancel PMI. Removal rules are based on your loan balance relative to your home's original value, along with payment history and other requirements. See how to get rid of PMI.
How to request a mortgage recast
- Call your servicer (the company you send payments to) and ask: Is my loan eligible? What's the minimum lump sum? What's the fee? How long does it take, and when will my new payment start?
- Make the principal payment exactly as the servicer instructs, so it's applied to principal.
- Pay the fee and sign the recast agreement.
- Confirm the new payment on your statement, and update any autopay amount.
Frequently asked questions
What does it mean to recast a mortgage?
Recasting a mortgage means making a large lump-sum payment toward principal and having your servicer recalculate your monthly payment based on the new, lower balance. Your interest rate and loan term stay the same, so your required monthly payment goes down.
Is a mortgage recast better than refinancing?
It depends on your rate and cash. A recast is usually better if you already have a good rate and have a lump sum, because it costs far less and keeps your rate. Refinancing is usually better if you can get a meaningfully lower rate, don't have a lump sum, or need to change the loan, such as removing a borrower.
Can you recast an FHA or VA loan?
Generally no. Recasting is mainly available on conventional loans, and many servicers, including Chase, state that FHA, VA and USDA loans aren't eligible. If you have a government-backed loan, refinancing is usually the main way to lower your payment.
How much does it cost to recast a mortgage?
Costs are set by your servicer. Many charge a processing fee, and some require a minimum lump-sum payment. Ask your servicer for the fee and minimum in writing. By comparison, Freddie Mac says refinancing typically costs 3% to 6% of the loan principal.
Does recasting a mortgage affect my credit?
A recast generally doesn't require a credit check, because you're keeping the same loan. Your loan must typically be in good standing to qualify.
Can I recast my mortgage more than once?
Some servicers allow it. Chase, for example, says you may be eligible to recast again after another principal reduction. Policies vary, so check with your servicer.
