The short answer
A refinance Loan Estimate shows the new loan's costs — but not what you're giving up or restarting. Three reset costs are invisible on the form: (1) prepaid interest — you'll pay interest twice on the overlap days between old payoff and new funding; (2) escrow reset — your old escrow balance is refunded (weeks later) while you fund a new escrow account at closing, a cash-flow gap; (3) the amortization clock restarts — refinancing a 30-year loan you've paid for 7 years into a new 30-year loan means 37 years of payments unless you choose a shorter term. Add these to the Loan Estimate's closing costs for the true comparison.
Reset cost #1: prepaid (overlap) interest
When you refinance, your old loan is paid off on the funding date, but interest accrues daily on both loans around the transition. You'll typically pay:
- Per-diem interest on the new loan from funding through month-end (shown on the Loan Estimate as "prepaid interest")
- Payoff interest on the old loan through the payoff date — your old servicer calculates this, and it's not on the new Loan Estimate
The overlap is usually small (a few days), but on a $400,000 loan at 6.5%, each day is about $71. Time your closing early in the month to minimize it — closing on the 5th means ~25 days of prepaid interest; closing on the 28th means ~2 days.
Reset cost #2: the escrow shuffle
Your current escrow account (taxes + insurance) gets closed when the old loan pays off. What happens:
- Old servicer refunds your escrow balance — but this takes 2–4 weeks after payoff, by law (RESPA requires refund within 30 days).
- New lender collects 2–6+ months of escrow at closing — shown on the Loan Estimate under "Initial Escrow Payment."
So for a few weeks you're double-funding escrow: money tied up in the old account awaiting refund, plus fresh cash deposited into the new one. On a $400,000 loan with $500/month escrow, that's $1,000–$3,000 of your cash temporarily locked. It's not a cost — you get it back — but it's a cash-flow demand the Loan Estimate doesn't flag.
Tip: you can often waive the new escrow account (with 20%+ equity) and pay taxes/insurance yourself, avoiding the double-funding entirely.
Reset cost #3: restarting the amortization clock
This is the big one. Amortization is front-loaded with interest — in the early years, most of your payment goes to interest, not principal. If you've paid a 30-year loan for 7 years, you're finally reaching the part where principal paydown accelerates.
Refinance into a new 30-year loan and you restart at year 1 — back to interest-heavy payments. Even at a lower rate, you may pay more total interest over the full term.
The fix: match or shorten your remaining term. If you have 23 years left, refinance into a 25-year or 20-year term — not a new 30-year. The monthly payment on a 20-year at a lower rate is often close to your current 30-year payment, and you build equity dramatically faster.
| Scenario ($400k balance, 7 yrs into 7.5% 30-yr) | New rate | Term | Total interest remaining |
|---|---|---|---|
| Keep current loan | 7.50% | 23 yrs left | ~$410,000 |
| Refi to new 30-yr | 6.50% | 30 yrs | ~$511,000 |
| Refi to 20-yr | 6.25% | 20 yrs | ~$290,000 |
The new 30-year lowers your payment but increases total interest by $100,000. The 20-year costs more monthly but saves $120,000 in interest. The Loan Estimate's "In 5 Years" box won't show you this — you have to run the full-term math.
The refinance break-even you should actually use
Don't just divide closing costs by monthly savings. The honest break-even:
True break-even = (closing costs + overlap interest + any escrow shortfall you'll cover) ÷ (monthly savings − lost principal paydown)
The "lost principal paydown" is the subtle part: your old loan was paying down principal faster (year 7 of amortization) than the new loan will (year 1). The payment savings overstate the benefit.
Methodology and limitations
Escrow refund timing follows RESPA (12 U.S.C. § 2609); lender practices on extension and re-lock vary. Amortization examples are illustrative at stated rates — your numbers depend on your actual balance, remaining term, and new rate. The Loan Estimate's "In 5 Years" disclosure is required by CFPB rules but is not a full-term cost picture. Rate data referenced is as of October 2026.
