You got a lump sum — a bonus, an inheritance, proceeds from selling a previous home — and you want a smaller mortgage payment. Your instinct says "refinance." But refinancing replaces your whole loan, resets closing costs, and could cost you a rate you'd never get back. There's a cheaper, quieter option most homeowners have never heard of: the mortgage recast. Here's how the two compare, when each one wins, and how to decide in today's market.
What a Mortgage Recast Actually Is
A mortgage recast (also called re-amortization) is simple: you make a large lump-sum payment toward your principal, then your servicer recalculates your monthly payment based on the lower balance spread over the remaining term. Your interest rate stays exactly the same. Your loan term stays exactly the same. The loan itself is never replaced.
Think of it this way: refinancing means getting a brand-new loan. Recasting means keeping the loan you already have and asking the servicer to update the math after you've paid down a chunk of it. Because no new loan is originated, there is no credit check, no appraisal, and no closing paperwork — just a small processing fee and a new, lower required payment within a month or two.
Illustration: a homeowner owes $400,000 with 25 years left on the loan. After selling a previous property, they put $100,000 toward the principal and ask for a recast. The servicer re-amortizes the new $300,000 balance over the remaining 25 years, and the required monthly payment drops — while the rate and payoff date stay untouched.
How a Recast Works, Step by Step
- Make a lump-sum principal payment. Servicers typically require a minimum lump sum before they'll recast (the minimum varies by servicer — ask yours). The payment must be clearly designated as a principal reduction, not a regular monthly payment.
- Ask your servicer to re-amortize. Recasting isn't automatic — you have to request it, usually in writing, and your servicer confirms your loan is eligible.
- Pay the processing fee. Most servicers charge a flat administrative fee, generally a few hundred dollars — a small fraction of refinance closing costs.
- Receive your new payment amount. The servicer sends an updated amortization schedule. Your new lower payment usually takes effect within 30 to 60 days.
The biggest caveat: not every loan qualifies. Conventional loans are most commonly eligible, but many government-backed loans — including most FHA and VA loans — typically cannot be recast, and servicers set their own rules and minimums. Before counting on a recast, call your servicer and ask three questions: Is my loan eligible? What's the minimum lump sum? What's the fee?
What Refinancing Does Instead
A refinance replaces your existing mortgage with a brand-new loan: new interest rate, new term, and a new round of closing costs — application fees, an appraisal, title work, and origination charges. The upside is that refinancing can do things a recast never can: change your rate, shorten your term, switch you from an adjustable rate to a fixed rate, or let you pull cash out of your equity.
The downside is cost and disruption. Closing costs are the price of admission, and they take time to recover through monthly savings. If you sell or move before the breakeven point, you've paid to lose money. Refinancing also requires you to re-qualify: credit check, income documentation, appraisal — the full process.
Recast vs Refinance: Side by Side
| Factor | Mortgage Recast | Refinance |
|---|---|---|
| What changes | Payment and balance only | Rate, term, and the loan itself |
| Upfront cost | Small flat processing fee | Closing costs — typically a few percent of the loan |
| Credit check | None | Required (hard inquiry) |
| Appraisal | None | Usually required |
| Interest rate | Stays the same | Can go up or down with the market |
| Loan term | Unchanged (same payoff date) | Can be shortened, extended, or restarted |
| Payoff speed | Payment drops, term doesn't shorten | Can pay off faster with a shorter term |
| Eligibility | Not all loans; FHA/VA often excluded | Most loan types |
| Best for | Lower payment now, keep a good rate | Lower rate, new term, or cash out |
Four Situations Where a Recast Wins
1. Your current rate is worth keeping. This is the number-one reason to recast. If you locked in a low rate years ago and today's market rates are higher, refinancing would trade up to a worse rate just to lower the payment. A recast keeps the valuable rate and still delivers payment relief.
2. You have a lump sum and want relief fast. A bonus, inheritance, or sale proceeds sitting in savings isn't working hard for you. Put a chunk of it into the mortgage and recast: the idle cash becomes immediate, permanent monthly breathing room, with almost no paperwork.
3. Your income or credit situation has changed. Retiring or going self-employed can make re-qualifying for a refinance difficult. A recast requires no income verification or credit check, so changed circumstances don't matter.
4. You don't plan to stay long enough for a refinance to pay off. Refinance closing costs take years to recover. If you might move or sell within a few years, the breakeven math may never work — while a recast's small fee pays for itself almost immediately.
Four Situations Where Refinancing Wins
1. Today's rates are meaningfully below your rate. A refinance captures the lower rate across the entire remaining balance — savings a recast can never deliver, since a recast leaves the rate untouched.
2. You want to pay off faster, not just pay less. A recast lowers the required payment but not the term. If your goal is a paid-off home sooner, refinancing into a shorter term does that.
3. You want to change the loan structure. Moving from an adjustable rate to a fixed rate, dropping mortgage insurance, or consolidating — these are all refinancing jobs. A recast changes nothing but the payment amount.
4. You need cash out of your equity. A cash-out refinance lets you borrow against your home's equity for renovations or other needs. A recast moves money in the opposite direction and provides no cash.
How to Decide: Four Questions
Cut through the noise with these four questions:
- Is your current rate better than what you'd get today? If yes, don't touch the rate — recast. If no, price a refinance.
- Will you keep the loan long enough to recover refinance closing costs? If you're unsure about your timeline, favor the recast's tiny fee.
- Does your servicer allow a recast? Call and ask. If the answer is no, the decision makes itself.
- Which matters more: a lower required payment, or a lower total cost? A recast wins on payment relief with minimal cost. A well-timed refinance wins on total lifetime cost when the rate drops enough. Run both scenarios through our mortgage calculator and compare the APR of each path.
One more sanity check before either move: confirm the new payment fits your budget with room to spare using your debt-to-income ratio. Payment relief only helps if the rest of your finances stay on track.
Frequently Asked Questions
Q: Does a mortgage recast change my interest rate?
A: No. A recast keeps your existing rate and remaining term; it only re-amortizes the lower balance, which reduces your required monthly payment.
Q: Does a recast shorten my loan term?
A: No. The payoff date stays the same. If you want to pay off faster, either make extra principal payments or refinance into a shorter term.
Q: Can I recast an FHA or VA loan?
A: Usually not. Many government-backed loans are not eligible for recasting. Conventional loans are the most commonly eligible, but always confirm with your servicer.
Q: Does requesting a recast hurt my credit score?
A: No. A recast involves no credit inquiry and no new account, so it doesn't affect your score. A refinance, by contrast, requires a hard inquiry.
Q: What's the difference between a recast and just making extra payments?
A: Extra payments reduce your balance and shorten the term, but they don't lower your required monthly payment. A recast lowers the required payment — it's the only option besides refinancing that does.

Next Steps
After reading this guide:
- Call your servicer and ask: is my loan eligible for a recast, what's the minimum lump sum, and what's the fee?
- Run the numbers on both paths: recast payment drop vs. refinance total cost after closing costs
- Check how long you'll keep the loan — if it's short, favor the recast's minimal fee
- If refinancing, shop multiple lenders and compare APRs, not just advertised rates
