⚡ RECAST vs CURTAILMENT — THE KEY DIFFERENCE
🔄 RECAST (Re-amortization)
- • Make lump sum → lender recalculates payment
- • Same rate · Same term · LOWER payment
- • Costs $150–$500 (vs $3,000+ to refinance)
- • No credit check · No appraisal
- ✅ Best for: monthly cash flow relief
💰 CURTAILMENT (Extra Principal)
- • Make extra payment → same required payment
- • Same rate · SHORTER term · Same payment
- • No fee · Available on FHA/VA too
- • No formal process — just pay extra
- ✅ Best for: paying off early, any loan type
Both save the EXACT SAME total interest — the only difference is whether you prefer lower payments or faster payoff.
Mortgage Recast vs Principal Curtailment 2026: Keep Your Low Rate, Cut Your Payment
Received an inheritance, bonus, or sale proceeds? You can lower your monthly mortgage payment by $200–$600/month without refinancing — keeping your 2020-era 3% rate intact — through a mortgage recast. Here's the exact math and how to request one. If your lender refuses, compare lenders who are recast-friendly.
Real Math: $50,000 Windfall on a $400K Loan
📊 Scenario: $400,000 remaining balance · 7.0% rate · 25 years left
| Option | Monthly Payment | Payment Change | Loan Term | Total Interest Saved |
|---|---|---|---|---|
| Do nothing | $2,660 | — | 25 years | — |
| Recast ($50K lump sum) | $2,327 | −$333/mo | 25 years | $87,000+ |
| Curtailment ($50K lump sum) | $2,660 | $0 | ~20 years | $87,000+ |
| Refinance (7.0% → 6.75%) | $2,592 | −$68/mo | 30 years | −$30K (resets term!) |
Key insight: Refinancing at similar rates resets your 30-year term and often costs MORE over the life of the loan despite looking cheaper monthly.
Mortgage Recast Requirements
Typical Recast Requirements
- ✅ Conventional loan (Fannie Mae / Freddie Mac)
- ✅ Minimum lump sum: usually $5,000–$10,000
- ✅ Loan must be current (no delinquencies)
- ✅ Remaining term: usually 5+ years left
- ✅ Recast fee: $150–$500 (paid upfront)
- ❌ NOT available on FHA, VA, USDA loans
- ❌ NOT available on loans with prepayment penalties
How to Request a Recast
- Call your loan servicer and ask: "Does my loan qualify for a recast/re-amortization?"
- Get the minimum lump sum requirement and recast fee
- Submit formal written recast request (servicer will provide form)
- Wire or send the lump sum payment
- Servicer processes within 30–60 days
- New payment statement reflects lower amount
If your current servicer doesn't offer recasting, compare lenders who actively promote recast options — you may be able to refinance to a recast-friendly servicer (only makes sense if rates are similar).
Recast vs Curtailment: Decision Framework
You want lower monthly payment NOW → Recast
Ideal for: retirees, people with variable income, or anyone who values cash flow flexibility over faster payoff.
You want to pay off the loan ASAP → Curtailment
Ideal for: people 5–10 years from retirement who want to enter retirement debt-free. Keep the same payment, shorten the term by 4–7 years.
You have an FHA/VA loan → Curtailment Only
FHA and VA loans cannot be recast. Extra payments go directly to principal, saving interest and shortening the term.
You need both lower payment AND flexibility → Consider HELOC
A HELOC lets you pay down your mortgage aggressively when cash is available, then borrow back if needed. More flexibility than a one-way recast.
Your Bank Won't Recast? Find One That Will.
Not all servicers offer recast programs. If yours doesn't, compare lenders with favorable recast terms. In some cases, a no-cost refinance to a recast-friendly servicer at the same rate makes sense.

What is mortgage recasting and how is it different from refinancing?
Mortgage recasting (also called re-amortization) is when you make a large lump-sum payment to your principal, and then the lender recalculates (reamortizes) your remaining monthly payments over the same remaining loan term at the same interest rate. Unlike refinancing: no new loan, no credit check, no appraisal, no closing costs. You keep your exact same interest rate. The lender just recalculates what your payment should be based on the reduced balance. Typical recast fee: $150–$500. Available on most conventional loans. NOT available on FHA, VA, or USDA loans. This is the perfect tool for someone who got a windfall but wants to keep a low 2020-2021 rate.
What is principal curtailment on a mortgage?
Principal curtailment is simply making an extra payment (lump sum or monthly) directly toward your principal balance — without a formal recast. The difference from recasting: your required monthly payment does NOT change. The extra payment reduces your balance and saves interest over time, but your minimum payment stays the same. You essentially "shorten" the loan term rather than "reducing" the monthly payment. Curtailment is available on any mortgage type (FHA, VA, conventional). When to choose curtailment over recast: if you want to pay off early and don't care about lower monthly payments, or if your lender doesn't offer recasting.
Recast vs curtailment: which saves more money?
Both reduce total interest paid by the exact same amount — because you're reducing the principal balance by the same dollar amount either way. The difference is CASH FLOW: Recast lowers your monthly payment immediately (better for cash flow flexibility). Curtailment keeps payment the same but shortens loan term (better if you want to pay off sooner). Example: $400K loan at 7%, 25 years left. You make a $50K extra payment. Both options save $87,000+ in interest over remaining term. Recast: payment drops from $2,660 to $2,327 (saves $333/month). Curtailment: same $2,660 payment but loan pays off 5 years earlier.
My lender won't offer a mortgage recast. What are my options?
If your lender won't offer a recast, options include: (1) Principal curtailment — make the large payment and keep the same payment. You pay off years early but don't get monthly payment relief. (2) Refinance — at current rates this only makes sense if your rate is already high. If you have a 2021-era 3% rate, do NOT refinance just for a recast. (3) Switch servicers — many lenders offer recast; if your servicer won't, ask if you can have the loan transferred. (4) Bi-weekly payments — won't reduce payment like a recast, but accelerates payoff somewhat. Common recast-friendly lenders: Bank of America, Wells Fargo, Chase, and many credit unions. Online lenders are often less flexible about recasting.
