Mortgage refinance rates have been sliding for weeks, and lenders are suddenly flooding inboxes with "it's time to refinance" pitches.
If you bought a home in 2023 or 2024 when rates peaked near 8%, the idea of shaving a full percentage point off your loan sounds like free money.
It usually isn't that clean, and a few details decide whether you actually save or just reset the clock on your debt.
The first thing to understand is that refinance rates run slightly higher than new-purchase rates, typically by 0.25% to 0.5%.
Lenders see a refi as less urgent business, and they price it that way.
So before you get excited about a headline rate of 6.3%, check what a refinance specifically would cost you, not what a fresh buyer would pay.
Those are two different numbers, and the gap matters more on a $400,000 loan than most people expect.
Closing costs are the silent deal-killer.
A typical refinance runs 2% to 5% of the loan amount, meaning a $350,000 balance could cost you $7,000 to $17,500 upfront.
Some lenders roll those fees into the new loan, which feels painless but quietly raises your balance and your monthly interest.
The real question is how many months of savings it takes to earn those costs back.
If your break-even point is 30 months and you plan to move in two years, you're not saving anything—you're prepaying for a benefit you'll never collect.
Refinancing from a 30-year loan you've paid on for seven years back into a brand-new 30-year term can lower your payment while adding years of interest.
A shorter term, like a 20-year or 15-year refi, often costs more per month but can save tens of thousands over the life of the loan.
Neither option is wrong, but they serve different goals.
Lower payment and lower total cost are not the same thing, and lenders rarely lead with that distinction.
A few situations genuinely favor refinancing right now.
If you have an FHA loan with mortgage insurance premiums, switching to a conventional loan once you've built enough equity can eliminate that monthly PMI charge entirely.
If you have an adjustable-rate mortgage about to reset, locking in a fixed rate removes a real risk.
And if your credit score has climbed 40 points or more since you bought, you may now qualify for a rate tier that wasn't available to you before.
Here's what to do before you call anyone.
Pull your current loan statement and write down the exact balance, rate, and remaining term.
Then ask at least three lenders for a Loan Estimate, which is a standardized form that makes comparison shopping actually possible.
Ignore advertised rates and look at the "Total Estimated Closing Costs" and "Monthly Principal and Interest" lines.
If a lender won't hand over a Loan Estimate in writing, that's your answer.
One more caution: refinancing resets the clock on your credit history for that loan, and a fresh mortgage inquiry can dip your score a few points.
Rate shopping within a short window, usually 14 to 45 days depending on the scoring model, typically counts as a single inquiry, so bunch your applications together rather than spreading them across months. **Our take:** Refinancing is a tool, not a windfall, and the break-even math is the only thing that matters.
Run the numbers with your actual closing costs and your actual timeline, and be honest about how long you'll stay in the home.
Final Thoughts
If the savings don't clear the costs comfortably before you'd sell, staying put is a perfectly smart move.
