A mortgage recast (or loan recast) is a one-time re-amortization of an existing mortgage after you make a large principal payment. The servicer applies your lump-sum principal reduction to the outstanding balance, recalculates the amortization schedule for the remaining term, and issues a new, lower monthly payment. The interest rate and original loan terms remain unchanged.
Why borrowers consider a recast (key benefits)
– Lower monthly payment without changing your interest rate or loan term.
– Small fee and minimal paperwork compared with refinancing (no credit check, usually no appraisal).
– Can reduce the total interest paid over the remaining life of the loan if you make a large principal payment.
– Can help you preserve a low mortgage rate if current market rates are higher than yours.
How a mortgage recast works (simple outline)
1. You make a lump-sum principal payment to the loan servicer.
2. The servicer applies that payment to the principal balance.
3. The servicer recalculates the remaining amortization schedule over the remainder of the original loan term.
4. The servicer issues a new monthly payment amount (typically lower because principal is lower), and you continue on the same loan with the same interest rate and maturity date.
Recast vs. refinance (compare and when to choose which)
– What a recast changes: monthly payment amount (lower) by reducing principal; loan interest rate and remaining term stay the same.
– What a refinance changes: replaces the original loan with a new loan, which can change rate, term, and loan type (and can eliminate or reduce PMI, change from ARM to fixed, etc.). Refinancing involves underwriting, an appraisal, closing costs and typically a credit check.
– Choose recast if: you have a significant lump sum, want a quick, low-cost way to lower monthly payments, and you’re happy with your current interest rate.
– Choose refinance if: current market rates are lower and you want a lower interest rate or shorter term, or you need to change loan features (e.g., remove or reduce PMI, convert ARM to fixed).
Types of mortgages eligible for recast
– Conventional (conforming, portfolio) loans are commonly eligible for recast.
– Government-backed loans—FHA, VA, and USDA—generally are not eligible for recasting through standard servicer programs. (Confirm with your servicer.)
– Some lenders have specific rules about minimum lump-sum amounts and frequency (e.g., only one recast allowed, or minimum $5,000–$25,000 principal payment).
Special case: negative amortization loans and Option ARMs
– Negative amortization loans and option ARMs allow payments that can be less than the interest due, creating deferred interest that increases principal. Those loans often include a scheduled or trigger-based recast to get the loan back to a fully amortizing schedule (or when principal reaches a limit).
– Option ARMs have payment options that can increase long-term principal; recasts or mandatory adjustments may be required under contract when deferred interest has accumulated or triggers are hit.
Example (illustrative)
– 30‑year fixed mortgage: $500,000 at 4% -> roughly $2,387 monthly principal & interest.
– After 10 years, you put $50,000 toward principal. If you do nothing else, keeping the old monthly payment shortens your loan by several years. If you ask for a recast, the servicer recalculates payments over the remaining 20 years, lowering your monthly P&I to roughly $2,080. (Example numbers are illustrative — exact amounts depend on amortization and timing.)
Practical disadvantages and limits
– You do not change the interest rate. If rates have fallen significantly since you originated your loan, refinancing might save you more.
– You typically do not shorten the loan term; monthly payment decreases but the maturity date stays the same. (You can, of course, keep paying the old higher payment to accelerate payoff.)
– Not all loans are eligible. FHA, VA, USDA loans commonly are excluded from recast programs.
– Lender policies vary: minimum lump-sum requirement, maximum number of recasts, and fees (often modest — e.g., a few hundred dollars).
– Escrow and PMI implications: recasting reduces principal and could change LTV, possibly affecting PMI cancellation thresholds; confirm with servicer.
Step-by-step: how to request a mortgage recast (practical steps)
1. Review your loan documents and servicer information to see if recasting is allowed or referenced.
2. Contact your loan servicer (phone or secure portal). Ask specifically:
• Do you offer mortgage recasts? If so, what are the eligibility rules?
• What is the minimum lump-sum principal payment required?
• What fee will you charge to process the recast?
• How long does the process take? Will my escrow account or insurance/taxes be affected?
• Will recasting affect my PMI or escrow setup?
3. Confirm the payoff/principal-reduction amount the servicer will accept and how to deliver the funds (certified check, wire, etc.).
4. Make the lump-sum principal payment as instructed. Keep documentation of the payment.
5. Pay the recast processing fee, if required.
6. Receive the new amortization schedule and new monthly payment amount in writing. Verify the effective date.
7. Update your budget or automatic payments to reflect the new payment. If you want to pay the old (higher) amount to accelerate payoff, set up the extra payment separately.
Checklist before you recast
– Do you have a lower interest rate available by refinancing? If so, compare net savings after closing costs.
– Are you comfortable keeping your current interest rate and term?
– Is your lump sum large enough to justify the process (and meet the lender’s minimum)?
– Will the recast affect PMI, property taxes, or homeowner’s insurance escrow?
– Confirm the servicer’s fee and the processing timeline.
– Confirm that the loan is a type your servicer will recast (conventional vs. government-backed).
When a recast makes sense — quick decision guide
– Yes to recast if: you have a sizable lump sum and want lower monthly payments quickly with minimal cost, and your current rate is attractive relative to the market.
– Consider refinance if: you want a lower interest rate, a shorter term, to remove mortgage insurance, or to change loan features (and you’re willing to pay closing costs).
Alternatives to recasting
– Make extra principal payments without formally recasting — this shortens your loan and reduces total interest but will not lower your monthly payment.
– Refinance to a lower rate or different term to change rate and term (but pay closing costs).
– Modify/shorten repayment voluntarily by increasing monthly payments.

Bottom line
A mortgage recast is a low-cost, low-friction way to reduce your monthly mortgage payment by applying a large lump-sum to principal and re-amortizing the loan. It does not change your interest rate or original maturity date and is most useful when you’re satisfied with your current rate and want lower monthly cash flow without refinancing. Always confirm your servicer’s specific policies, fees, and eligibility before you act.
