Recast vs Refinance a Mortgage — What's the Difference?

TL;DR: Recasting and refinancing sound similar but solve different problems. A recast keeps your rate and lowers your payment. A refinance replaces the whole loan.

If you're weighing a mortgage recast vs. a refinance, the honest answer is: they solve different problems. A recast keeps your existing loan and rate but re-amortizes the payment down after a lump-sum principal payment — cheap and simple. A refinance replaces the loan entirely with a new one (new rate, new term, new closing costs, new credit check) — expensive but flexible.

Okoniq Property Hub tracks your mortgage, principal history, and refinance offers in one place so the comparison is clear. Here's how each one actually works.

What is a recast?

You send the lender a lump-sum principal payment (typically minimum $5,000–$25,000 depending on the servicer), and they re-amortize the loan over the remaining term. Same interest rate, same maturity date, lower monthly payment.

Example: 25 years left on a $250,000 balance at 7%, $1,660/month P&I. Pay $50,000 down → new balance $200,000 → new payment $1,414/month over the same 25 years. Same rate, same payoff date, $246/month lower payment.

• Fee: Usually $200–$500 (some lenders do it free for existing customers).
• Credit check: None.
• Requires: Lender must offer recasts. Most conventional loans allow it; FHA and VA generally do not.

What is a refinance?

You replace the current loan with a new one. New rate, new term, new closing costs, new credit check, new escrow, new everything.

Example: 25 years left on $250,000 at 7% ($1,660/month) → refi to a fresh 30-year at 6% → new payment $1,499/month P&I. Lower rate + longer term = big monthly drop, but you've reset the clock and paid closing costs.

• Fee: $3,000–$6,000 typical.
• Credit check: Yes — hard inquiry, income + asset docs, appraisal.
• Requires: Ability to qualify with today's income and debt-to-income ratio.

When does each one win?

Choose a recast when:

• You've come into a lump sum (bonus, inheritance, home sale proceeds) and want to lower payment
• Current rate is already fine — you don't need a new rate
• You want to avoid closing costs and paperwork
• You want to keep your existing tax-treatment and escrow

Choose a refinance when:

• Market rates have dropped enough that break-even math works — see how to calculate refinance break-even in 60 seconds
• You want to change the loan term (30 → 15, or lengthen for cash flow)
• You want to switch loan types (ARM → fixed)
• You want to take cash out (cash-out refi)

The two aren't mutually exclusive — some homeowners refinance to a better rate and then recast a few years later after a windfall.

Do both actually save interest?

Yes, but through different mechanics:

• A recast saves interest because the balance you're being charged interest on is smaller. Total interest paid over the remaining term drops by the difference between "old interest curve" and "new smaller-balance interest curve."
• A refinance at a lower rate saves interest because the rate charged on every remaining dollar is lower. Total interest paid drops more per rate point but is offset by closing costs.

For a $50,000 lump sum at 7%, a recast might save $40,000–$60,000 in future interest without touching the rate. A refinance to a 1.5% lower rate might save more — but only after eating $4,000+ in closing costs and hopefully staying long enough to earn it back.

Can I do both?

Sometimes. Refinance first (get a better rate), then recast later after a lump sum. But some new loans have a 12-month waiting period before allowing a recast, and some servicers don't allow recasts on jumbo loans. Ask your loan officer before assuming.

Keep your mortgage options clear

Every homeowner should know which one their loan supports and roughly what a recast at their current lender would cost. Okoniq Property Hub stores your loan docs, servicer, and recast policy so the decision is a lookup, not a phone tree.

Frequently asked questions

Does recasting hurt my credit?

No — no credit inquiry, no new loan.

What's the minimum lump sum for a recast?

Varies by servicer — commonly $5,000–$10,000 principal-only minimum, sometimes $25,000. Ask your servicer's payoff/servicing line.

Can I recast an FHA or VA loan?

Usually no — these programs typically require a full refinance (streamline refi programs available) rather than a recast. Confirm with your servicer.

Not financial advice. The right choice depends on your rate, remaining term, and cash situation — consult a licensed mortgage broker. Okoniq Property Hub keeps the underlying loan details ready for that conversation. Get started free.

FAQ

How much does it cost to recast a mortgage compared to refinancing?

A recast typically costs $200–$500 (sometimes free), while a refinance runs $3,000–$6,000 in closing costs. Recasting avoids appraisal fees, title insurance, and origination charges because you're keeping the same loan.

Can I recast my mortgage more than once?

Most lenders allow multiple recasts over the life of the loan, though some impose waiting periods (commonly 12 months) between recasts. Each time requires meeting the lender's minimum lump-sum threshold and paying the recast fee again.

Will refinancing save me more money than recasting if rates dropped 1%?

It depends on how long you stay in the home. A 1% rate drop saves more interest per month than a recast, but closing costs delay break-even by 2–4 years. If you're staying long-term and rates fell meaningfully, refinancing usually wins; if you're moving soon or rates only dropped slightly, a recast keeps more cash in your pocket.

Does a recast shorten or extend my loan term?

Neither — a recast keeps the exact same maturity date. Your lower payment results from spreading a smaller balance over the same remaining years, not from adding time like a refinance might.
