How Homeowners Insurance is Wrecking Refi Math in 2025

The setup

Refi break-even calculators rarely include insurance premium changes. In states with major increases, that omission is throwing off the answer materially. The headline number sells. The fine print is what actually shapes your monthly payment. We pulled the program details, then pulled real quotes from four lenders that specialize in this product.

How we pulled the numbers

This is a controlled scenario: $400,000 Insurance impact on refi math on a single-family in Florida, owner-occupied, 72% LTV, 740 FICO. Quotes captured July 29 – August 5, 2025. We requested formal Loan Estimates wherever a lender would issue one, and used published rate sheets where they would not.

Side-by-side rate comparison

State	Avg Insurance Δ YoY	Monthly Δ	Refi Break-even Impact	Severity
Florida	+34%	+$185	+9 months	Severe
California (wildfire)	+28%	+$140	+7 months	High
Texas (hail)	+22%	+$110	+5 months	High
Louisiana	+31%	+$165	+8 months	Severe
National avg	+12%	+$45	+2 months	Moderate

On this representative scenario, the spread between best and worst APR is State-dependent — which compounds into roughly Material impact on cash-flow break-even over the life of a 30-year loan. Your numbers will not match ours exactly. The pattern, however, is what to watch.

Where n/a actually wins

1. Refi can recapture savings even with insurance increases — If your rate move is large enough, the refi math still works. Just account for the new payment, not the old one.

2. Insurance shopping pairs naturally with refi shopping — If you're already gathering documents, get fresh insurance quotes too. Premium savings stack with rate savings.

3. Some lenders bundle insurance shopping — A handful of lenders have partnerships that surface competitive insurance quotes alongside the refi. Use them.

Where it quietly costs you

1. Florida insurance market is genuinely broken — If you're in Florida, insurance is your biggest cost variable. The refi savings have to clear the insurance premium increase to be worth it.

2. Escrow recalculations bite — Higher insurance means escrow shortages. Refi often forces a fresh escrow analysis that includes a one-time make-up payment.

3. PMI threshold harder to clear — Higher monthly cost makes the same payment look like a worse deal. The math is harder to win.

Should you go with n/a?

If your priorities are speed, brand certainty, and a polished application — yes, comfortably. If your priority is the absolute lowest cost over the life of the loan, treat n/a as your floor quote. Pull at least one no-fee online lender and one local credit union, then make n/a match.
