Mortgage Recast vs Refinance 2026: Which Saves More Money?
By the 3Tej Research Desk · Published May 23, 2026 · 3 min read
- Recast: lump sum principal payment + lender reamortizes; you keep the same rate, term, and loan
- Refinance: brand new loan replacing the old one, new rate, new term, new closing costs
- Recast fee: usually 250 to 500 USD. Refinance closing costs: 2 to 5% of the loan
- Recast wins when rates have risen and you want a lower monthly payment from a windfall
- Refinance wins when rates have dropped or you want to change the term
Two distinct ways to lower your monthly mortgage payment after you receive a windfall (inheritance, RSU vest, bonus, home sale proceeds): mortgage recast and mortgage refinance. They achieve similar-looking results (lower monthly payment) by completely different mechanics. Recast costs a few hundred dollars; refinance costs thousands. Recast keeps your existing rate; refinance gives you the option to change it. The right choice depends on whether rates today are higher or lower than your existing rate.
What is a mortgage recast?
A mortgage recast (also called reamortization or loan curtailment) is when you make a large lump-sum principal payment, and your lender recalculates the monthly payment based on the new lower balance. The interest rate, the remaining term, and the loan itself do not change. Only the monthly payment goes down.
Most conventional Fannie Mae loans allow one recast per year for a flat fee of 250 to 500 USD. FHA, VA, and USDA loans typically do NOT support recasting. Jumbo loans vary by lender. Confirm with your servicer.
What is a mortgage refinance?
A refinance replaces your existing mortgage with a brand-new mortgage. You apply, qualify, appraise, and close again. The new loan can have a different rate, a different term, a different lender, and a different loan amount (cash-out refinance) or the same.
Closing costs run 2 to 5% of the new loan amount, typically 6,000 to 15,000 USD. The math depends entirely on how long you plan to stay in the home and whether the new rate is materially lower than the old one.
Side-by-side: recast vs refinance
| Attribute | Recast | Refinance |
|---|---|---|
| Interest rate | Unchanged | Changes to current market rate |
| Loan term | Unchanged | Can change (15, 20, 30 year) |
| Monthly payment | Lower (math of new balance over remaining term) | Depends on rate AND term |
| Cost | 250 to 500 USD flat fee | 2 to 5% of loan amount |
| Time to complete | 1 to 4 weeks | 30 to 60 days |
| Credit check / income verification | Usually no | Yes, full underwrite |
| Cash-out option | No | Yes (cash-out refinance) |
| Eligibility | Conventional Fannie/Freddie only | Any loan type |
Worked example: when to recast vs refinance
Scenario: you have 8 years into a 30-year fixed at 3.5% with 280,000 USD remaining balance. You just received 75,000 USD from an inheritance. Current market refinance rate is 6.5%.
- Recast path. Pay 75,000 USD as principal curtailment. New balance: 205,000 USD. Lender reamortizes the remaining 22 years at 3.5%. New monthly payment drops from 1,257 to 921 USD. Cost: 350 USD. Total interest saved over remaining term: 41,000 USD. You keep the 3.5% rate forever.
- Refinance path. Pay 75,000 USD as down payment, refinance 205,000 USD at 6.5% over a new 30-year term. New monthly payment: 1,296 USD (HIGHER than the recast despite the lower balance, because the rate is way up and the term restarts). Closing costs: 9,000 USD. This is strictly worse here.
Recast wins decisively when current rates are higher than your existing rate. The math flips when rates are LOWER than your current rate; then refinance can recoup its closing costs.
When refinance is the right call
Refinance wins in three situations:
- Rates have dropped 0.75% or more. The classic break-even is roughly 18 to 30 months at a 1-point rate drop, depending on closing costs. Use a refinance break-even calculator for your specific numbers.
- You want to change the term. Recast only adjusts the monthly payment; the remaining term stays put. To compress a 30-year into a 15-year or stretch a 15-year into a 30-year, you need a refinance.
- You want to pull cash out. Cash-out refinance lets you tap home equity for a renovation, debt consolidation, or college tuition. Recasting does the opposite (puts cash IN); there is no equivalent cash-out recast.
Frequently asked questions
Does a mortgage recast require a credit check?
Usually no. Recasts are mechanical reamortizations; the loan, rate, and term do not change, so there is no new underwrite. The lender charges a flat fee (250 to 500 USD) and recalculates the monthly payment using the new balance over the remaining term.
Can I recast an FHA, VA, or USDA loan?
Generally no. Recasting is mostly a conventional-loan feature. Government-backed loans do not support reamortization; the equivalent if you have a windfall is to make a large principal payment and either accept the same monthly payment (loan pays off earlier) or refinance into a conventional loan.
How long after closing can I recast?
Most lenders require you to have made at least 2 to 6 payments before they will recast. Some Fannie Mae servicers allow recast within 90 days of closing for a fee. Check with your specific servicer.
Is recasting better than just paying extra principal?
Extra principal payments shorten the loan term without changing the monthly payment. Recasting locks in a LOWER monthly payment but keeps the same payoff date. If your cash flow is tight, recast. If your cash flow is fine and you want to be debt-free sooner, just make extra payments.
Do I need to recast or can I just send a large principal payment?
A large principal payment without recasting reduces your loan balance and shortens the payoff date, but does NOT lower your minimum monthly payment. Recasting reamortizes the remaining balance over the remaining term, lowering the monthly payment too. The 250 to 500 USD fee is the price of getting both effects.
