Altgage Inc.

Your interest rate doesn't change. Your payoff date doesn't change. Your monthly payment drops to reflect the smaller balance. Recasts typically cost $200–$500 and most lenders allow them after at least one or two on-time payments since closing.
If freeing up monthly cash flow matters most — more breathing room in the budget, lower required payment for the rest of the loan — recasting is the only move here that actually reduces your minimum payment. You pay down principal AND you pay less every month going forward. The trade-off: that money is now locked in your home equity. It's no longer liquid.
If the lump sum is your entire emergency fund or close to it, the right call may be to keep the money liquid in a high-yield savings account and make smaller extra principal payments monthly. Yes, you pay more total interest. But losing access to that capital during a job loss or medical event can cost far more than the interest savings. A reasonable middle ground: keep 6–12 months of expenses in HYSA, then recast or prepay with whatever is above that.
Two scenarios make recasting the wrong move. First, if you don't have a healthy emergency fund — recasting locks money into a home you can't easily tap. Second, if your loan rate is meaningfully below current market rates (say a 3% mortgage in a 7% world). That cheap loan is an asset. Paying it down faster is like prepaying a discount — you give up the spread. In the extreme version of this argument, some borrowers with sub-3% loans deliberately pay the minimum forever and invest the difference.
Every dollar of extra principal you pay early permanently knocks out all the future interest that dollar would have accrued. On your 30-year mortgage at 6%, $1,000 paid in year 1 saves roughly $4,673 in interest over the life of the loan; the same $1,000 paid 5 years before payoff saves only $349. That's why the Pay-from-HYSA strategy keeps working even after the pool runs out: the principal you knocked down during the drip phase is permanently ahead of the standard amortization schedule, so the loan finishes years sooner. For a deeper look, see the Prepay Curve Calculator — it visualizes value-per-dollar by year.
Recasting is a servicer transaction, not a new loan. There’s no application, no appraisal, no credit pull, and no closing.
Call your servicer and ask two questions: do you recast this loan, and what is the minimum principal reduction. The answers vary more than people expect. Many servicers set a floor somewhere in the $5,000–$10,000 range, some require the balance to drop by a set percentage, and some don’t offer it at all. Get the answer before you send the money — a large principal payment made in the hope of a recast is just a prepayment if the servicer says no, and prepayments don’t lower your monthly payment.
If they do recast, you send the lump sum, pay the processing fee, and sign a modification agreement. The servicer re-amortizes the remaining balance over your remaining term at your existing rate and issues a new payment schedule, typically effective within one or two billing cycles.
One thing worth confirming in writing: that the lump sum is applied to principal before the re-amortization, not held in suspense. Ask for the new schedule showing the balance and payment, and check it against what you sent.
Conventional loans backed by Fannie Mae or Freddie Mac generally permit recasting, subject to your servicer’s own rules. FHA, VA and USDA loans generally do not — government loan programs don’t provide for re-amortization, so borrowers with those loans looking for a lower payment are usually looking at a refinance instead. Jumbo and portfolio loans depend entirely on who holds the note; some allow it readily, some don’t offer it at all.
Servicing also gets sold. The company that told you at closing that recasting was available may not be the company holding your loan in year six. Confirm with whoever is servicing it now.
These three do different jobs and people routinely pick the wrong one.
Recast keeps your rate and your payoff date and lowers your monthly payment. It costs a few hundred dollars and requires a lump sum. Use it when your rate is already good and you want breathing room in the monthly budget.
Refinance replaces the loan. It can lower your rate, change your term, or pull cash out — but it costs thousands in closing costs, requires underwriting, and resets the amortization clock unless you deliberately match your remaining term. Use it when the rate is the problem. Run the refinance breakeven if that is the question.
Paying extra shortens the loan and saves the most interest per dollar, but it never lowers your required payment. Use it when your goal is being done sooner, not paying less each month — the mortgage payoff calculator models that path.
The decision usually collapses to one question: is your current rate the problem, or is your current payment the problem? A rate problem needs a refinance. A payment problem needs a recast. A “how fast can I be done” problem needs extra payments. If your rate is meaningfully below the market, a recast is often the only one of the three that doesn’t cost you the loan you already have.
A mortgage recast is a one-time re-amortization of your existing loan around a smaller balance after you make a large principal payment. Your interest rate and payoff date stay the same; only the monthly payment drops. It typically costs $200–$500 and requires no credit check, appraisal, or new loan.
Most servicers charge a processing fee in the $200–$500 range. Beyond the fee, the real cost is the lump sum itself — that money moves from liquid savings into home equity, where you can’t reach it without borrowing against the house or selling it.
It depends on your servicer; there’s no universal rule. Some allow one recast per loan, some permit it periodically as long as each lump sum clears their minimum, and some don’t offer it at all. Ask your servicer directly rather than relying on what you were told at closing, since the loan may have been sold since then.
Generally no. FHA, VA and USDA loans don’t provide for re-amortization, so borrowers with those loans who want a lower payment are usually looking at a refinance instead. Recasting is mainly available on conventional loans, subject to the servicer’s own rules.
It depends on whether your problem is the rate or the payment. Recasting lowers the payment while keeping your existing rate, costs a few hundred dollars, and requires no underwriting — so it’s the better move when your rate is already good. Refinancing is the better move when a lower rate is available and the closing costs pay back within your expected time in the home.
The money becomes illiquid, and you don’t finish the loan any sooner. A recast converts accessible savings into home equity that requires a HELOC, a cash-out refinance, or a sale to reach again — and because the payoff date doesn’t move, you save less total interest than you would by making the same payment as a straight prepayment.
No. A recast isn’t a new loan, so there’s no application, no hard credit inquiry, and no new tradeline. The account continues reporting with the same origination date and a lower balance.
