What is mortgage recasting?

Mortgage recasting (re-amortization) reduces your monthly payment without changing your interest rate or loan term. You pay a lump sum toward principal, and the lender recalculates the remaining payments based on the new lower balance over the original remaining term. Cost: $250-$500 fee. Minimum lump sum: typically $5,000-$10,000. Available on conventional and most jumbo loans; NOT available on FHA, VA, or USDA loans (those require refinancing to reduce payment).

When is recasting better than refinancing?

Recast beats refinance when: (1) Your current rate is at or below market rate (preserves the locked-in low rate); (2) You have a lump sum available ($5K+) but don't want to commit to refinance closing costs ($3K-$10K); (3) You want to keep the same loan term (recast doesn't reset the clock); (4) You don't qualify for refinance due to recent income changes or credit score drop. Refinance beats recast when: your current rate is 0.75%+ above market, you want a different loan term, or you need to access equity (cash-out refi).

How much can a recast lower my mortgage payment?

Roughly: every $100,000 lump sum reduces a 30-year fixed payment by ~$567/month at 5.5% rate, ~$645/month at 6.7%. Worked example: $300K mortgage at 5.5% (payment $1,703/mo). Add $50K lump sum, recast → balance $250K, new payment $1,419/mo. Monthly savings $284. Break-even on $250 fee = 1 month. If you have a lump sum sitting in savings earning 4% APY, recasting that toward a 5.5%+ mortgage immediately yields the rate spread risk-free.

Why are FHA and VA loans not eligible for recasting?

FHA and VA loan structures require uniform amortization throughout the term — the loan agreements don't permit mid-term re-amortization. To reduce payment on these loans, you must refinance: FHA Streamline Refinance, VA Interest Rate Reduction Refinance Loan (IRRRL), or full conventional refinance after building 20% equity. The IRRRL is essentially "recasting equivalent" for VA — limited credit/income docs but does reset the clock and require a new appraisal-free closing.

Do extra principal payments achieve the same result as recasting?

NO — different mechanics. Extra principal payments shorten your payoff timeline (you finish earlier) but do NOT lower your required monthly payment. Recasting LOWERS the required payment but extends/maintains the original term. So extra principal saves more total interest because the loan is paid off faster; recasting lowers monthly cashflow burden. Best of both: pay extra principal regularly, then recast every 2-3 years to lower your required payment for cashflow flexibility.

How often can I recast my mortgage?

Most lenders allow recasting once per year per loan, but some allow up to 2-3 times per year. Each recast carries the full fee ($250-$500). Strategy: rather than 4 small recasts at $250 each ($1,000 total), batch principal additions and do one large recast per year. Recast eligibility resets each calendar year (or 12 months from previous recast — check your specific servicer). Some servicers may waive fees for VIP customers or large lump sums ($50K+).

Does recasting affect my credit score?

No — recasting does NOT affect credit score. Unlike refinancing (which is a NEW loan triggering hard inquiry, debt-to-income reassessment, and possible credit score drop of 5-15 points), recasting is just an internal adjustment to your existing loan terms. The original loan account remains the same; only the amortization schedule changes. Your payment history continues uninterrupted. This is a meaningful advantage for borrowers planning future credit-sensitive purchases (car, business loan, second home).

Can I recast a mortgage I just got?

Most lenders require a "seasoning period" before allowing recast — typically 90 days to 12 months after origination or last recast. Conventional loans (Fannie/Freddie) usually allow recast after 90 days seasoning. Jumbo and portfolio loans vary 6-12 months. The seasoning prevents borrowers from exploiting recast immediately after closing (e.g., timing arbitrage). If you came into a windfall right after closing, you can still pay extra principal immediately — you just have to wait the seasoning period before formal recast.

Mortgage Recasting 2026 — Complete Comparison vs Refinance & Extra Payments

Short answer: Mortgage recasting reduces your monthly payment by adding a lump sum to principal — without changing your rate or term. $250-$500 fee, $5K-$10K minimum lump sum, available on conventional/jumbo loans. NOT available on FHA, VA, USDA. Recast beats refinance when you want to keep your low locked-in rate. $100K lump sum at 5.5% rate → ~$567/month savings, payback in 1 month. Doesn\'t affect credit score (no hard inquiry or new loan).

Recast vs refinance vs extra payments

Method	Cost	Impact	Lump sum needed	When best	Notes
Recast (re-amortize)	$250-$500 fee	Lower monthly payment, same term, same rate	$5K-$10K minimum typical	Have lump sum + want lower payment + keep low locked rate	Eligibility: conventional/jumbo most lenders; FHA/VA NOT eligible
Refinance	$3K-$10K closing costs	New rate, new term, new payment	No minimum (cash-out optional)	Current rate >0.75% above market OR want different term	Resets clock; full underwriting required; appraisal needed
Extra principal payments	Free	Same payment, faster payoff (or save and recast later)	Any amount	Building toward recast; or want guaranteed interest savings	Doesn't lower required payment until recast
Bi-weekly payments	Free (or $200-$400 service fee — DON'T pay)	13 monthly payments per year vs 12; ~5 years off 30-yr	No	Steady cashflow + want forced extra principal	Self-implement by paying half-payment every 2 weeks; servicer fees scam

Decision flow — when to use which

Q1: Is your current rate at least 0.75% above today\'s market rate?

→ YES: Refinance (rate savings outweigh closing costs in most cases).
→ NO: continue to Q2.

Q2: Do you have a lump sum of $5,000+?

→ YES: Recast (keep low rate, lower payment).
→ NO: continue to Q3.

Q3: Do you want to pay off faster?

→ YES: Extra principal payments (free, faster payoff).
→ NO: continue current schedule or biweekly.

5 common recasting mistakes

Paying servicer "biweekly mortgage" fees ($200-$400/year). You can implement biweekly yourself for free by paying half your monthly amount every 2 weeks — same effect, $0 cost.
Recasting an FHA/VA loan. Not eligible. Use FHA Streamline or VA IRRRL refinance instead.
Recasting after refinancing. If you JUST refinanced into a low rate, recasting forces another fee. Time recasts mid-cycle.
Recasting too small a lump sum. $5K minimum on a $300K loan = $28/mo savings = doesn\'t cover the $250 fee for 9 months. Save up to $20K+ before recasting.
Forgetting investment alternative. If your mortgage is at 4.5% but you can earn 4.5%+ in CDs/I-bonds tax-equivalent, recast may be neutral. Run the math: marginal mortgage rate AFTER tax deduction (if itemizing) vs after-tax CD/bond return.
