The Quick Read: It depends on your goal, your cash, and who holds your loan. A refinance replaces the loan and re-tests your credit, income, and home value. A recast keeps the loan and lowers only the required payment after a large principal payment, if your servicer allows it. Keeping the loan costs nothing and often wins when the current terms still fit.
The honest answer comes down to what you are trying to change. Refinance is for borrowers who need a different rate, term, or structure, or who want to pull equity out. Recast is for borrowers who already like the loan, have a large lump sum, and want a smaller required payment without starting over. Keeping the loan is for everyone whose terms still work, and for borrowers who can simply send extra principal on their own schedule.
Refinance savings and break-even estimate

Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $245,000 current balance, a current rate you enter and a remaining term seeded at twenty-five years, closing costs seeded at $5,000 as an editable placeholder (not a fee quote) and rolled into the new loan, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

Treat the recast column as "generally." Recast policy is set by whoever holds your loan, and it varies on jumbo files.
What Each Option Actually Is
A refinance is a new loan that pays off the old one. The CFPB notes that borrowers usually pay closing costs and fees, and that a lower payment can come from a longer term rather than a better deal. Check how much of any drop comes from the longer term.
A recast has a different name in agency language: re-amortization. Under the Fannie Mae Servicing Guide, a servicer may agree to reduce only the principal-and-interest payment after a substantial principal payment. It re-amortizes the current balance at the current rate over the remaining term. The rate, the maturity date, and the note do not change.
Keeping the loan means no action. You can still send extra principal. The required payment stays put, but the payoff moves up and total interest falls.
Why Jumbo Changes the Recast Question
Here is the catch most explainers skip. Fannie Mae's recast language governs loans Fannie Mae owns. A jumbo loan sits above the conforming limit, so those rules do not automatically apply. Per the FHFA, the limit is reset annually, and county limits differ. Whether you are "jumbo" depends on your county and the year.
On a jumbo, recast is the call of the lender or investor that holds the loan. Some allow it. Some allow it with conditions. Some do not. Public sources on this are mostly secondary, so treat it as policy to confirm, not a right.
Before you plan around a recast, ask your servicer these in writing:
- Do you recast this loan, and does the investor allow it?
- What is the minimum lump sum?
- Is there a servicer fee?
- Is there a waiting period or a limit on how often?
- Must the payment be designated as principal-only?
- Does an interest-only period make the loan ineligible?
An undesignated payment can be applied to future scheduled payments, which defeats the point. Designate it. A loan also generally has to be current. If it is delinquent, extra principal cures the delinquency first.
When Refinance Is the Better Fit
Refinance wins when you need something a recast cannot do. A recast cannot change the rate, shorten the term, convert an adjustable loan, or remove mortgage insurance. It cannot pull cash out.
Refinance fits when:
- You want a different structure: fixed, adjustable, or interest-only.
- You want to refinance out of jumbo status. If your balance has fallen or the county limit has risen, a conforming loan may be possible. Check your county limit on the FHFA conforming loan limit page.
- You do not have a large lump sum.
- You want cash out for a real purpose.
- Your servicer will not recast.
Here is how the jumbo programs Lendmire places generally work. The wholesale jumbo loan programs reach up to 90% leverage on the headline lane, with a 660 decision score and loans up to $5,000,000 on the largest lanes. Several lanes stop at 89.99% CLTV and the rest stop at 80%. The ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lanes, and 43% on the interest-only lanes. Cash-out sits at lower leverage than purchase, with a cash cap on the largest lanes. All of this is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Reserves and appraisals scale with the amount. Reserves are counted in months of the full payment and rise with loan size. Above a lane's threshold amount, two appraisals are required. Both are friction a recast skips.
Run the break-even honestly. Divide total closing costs by the monthly savings. The result is the number of months you need to stay to recoup them. If you may move soon, the CFPB's refinance handout lists that as a reason a refinance may not make sense. So are a weaker credit standing and a prepayment penalty on the current note.
Two cautions. A refinance pays off the whole loan, which can trigger a prepayment penalty if your note has one, usually within the first few years. And "no-closing-cost" refinances are a marketing term. The costs are built into the rate or the balance, not erased.
A refinance also re-tests the file. Income, assets, credit, and value are all reviewed fresh. If your profile has weakened since origination, a refinance may come back different from what you expect. A recast avoids that review.
When a Recast Is the Better Fit
Recast wins for the borrower who already likes the loan. Picture a homeowner who sold another property, received a bonus, or inherited cash, and holds a loan with terms they would not want to give up. A recast lowers the required payment without a new appraisal, credit pull, or new underwriting. Generally there is no Loan Estimate or Closing Disclosure either, since no new loan is created.
Recast fits when:
- Your current rate and term are already right.
- You have a lump sum well beyond your emergency cushion.
- Your servicer confirms the loan is eligible.
- You want a lower required payment, not just a faster payoff.
- You do not need cash out or a structural change.
The risk is liquidity. Cash sent to principal is locked into home equity. It is not easy to get back out later, and a new borrowing event means a new review. Jumbo lenders care about reserves, and so should you. Keep a cushion after the paydown.
A recast also does not shorten the term. If you want the loan gone sooner, extra principal does that on its own, with no servicer permission.
When Keeping the Current Loan Is the Better Fit
Do nothing is a real answer. It wins when the existing terms fit your plan, when you expect to move before a refinance would pay back its costs, or when your servicer will not recast and the refinance numbers do not pencil.
It also wins when you are unsure. You lose no flexibility by waiting. A borrower can send extra principal in any month, subject to the terms of the loan. The payment stays the same, but interest falls and the payoff date moves up. If you later find the servicer allows a recast, you can still do one.
Keep the loan if:
- Your terms already suit your goals.
- Break-even on a refinance is longer than you plan to stay.
- Your credit or equity picture is weaker than at origination.
- Your note carries a prepayment penalty that a refinance would trigger.
- You want to preserve cash.
Check the note before any big move. A large lump sum could in some cases touch a penalty provision, so confirm the terms either way.
Key Terms Defined
Refinance: A new mortgage that pays off and replaces your current one.
Recast (re-amortization): A servicer re-calculates your required payment on the current balance, at the same rate and remaining term, after a large principal payment.
Jumbo loan: A mortgage above the county's conforming loan limit, so it is outside Fannie Mae and Freddie Mac purchase eligibility.
Servicer: The company that collects your payment and manages the loan day to day.
Principal curtailment: An extra payment designated to reduce the loan balance.
Prepayment penalty: A charge that may apply if you pay the loan off early, usually within the first few years.
Break-even: The number of months of savings needed to recoup closing costs.
A Short Decision Path
Work it in order.
1. Ask whether you have a lump sum beyond your cash cushion. If not, a recast is off the table.
2. Ask your servicer whether it recasts your jumbo loan. If not, move to refinance or keep.
3. Compare what you want to change. If it is rate, term, structure, or cash out, only a refinance does it.
4. Run the break-even against how long you expect to stay.
5. Check the note for a prepayment penalty.
6. If nothing clearly beats your current loan, keep it and send extra principal as you can.
The Balanced Verdict
Refinance is the tool for changing the loan. Recast is the tool for lowering the required payment on a loan you like, when your holder allows it. Keeping the loan is the tool for everyone else, and it is more often right than people expect.

Frequently Asked Questions
Can I recast a jumbo loan?
Sometimes. Recast on a jumbo is set by the lender or investor holding the loan, not by agency rules. Ask your servicer for its minimum lump sum, any fee, and any waiting period in writing before you plan around it.
Does a recast change my interest rate or loan term?
No. A recast re-amortizes the current balance at the same rate over the remaining term. Only the required principal-and-interest payment changes. Taxes and insurance are generally unaffected, though your servicer can confirm.
Do I need a credit check or appraisal for a recast?
Generally not. Those are features of a refinance, which is a new credit decision with a new valuation. Confirm with your servicer, since policies differ on jumbo loans.
Is making extra payments the same as a recast?
No. Extra principal shortens your payoff and cuts total interest, but your required payment stays the same until the servicer recasts it. Extra payments need no approval, which makes them a flexible starting point.
Can I refinance out of a jumbo loan?
Possibly, if your balance is now at or below your county's conforming limit. Limits are reset each year and vary by county. A refinance is the only one of the three options that can change the loan type.
