Mortgage refinance rates have been sliding for months, and lenders are suddenly very eager to remind you of it.
Ads promising lower payments are showing up in mailboxes and inboxes across the country.
If you bought a home in the last two years, it's worth a closer look, but not for the reason the ads suggest.
Most homeowners who bought after 2022 locked in rates that were high by recent standards, often in the 6.5 to 7.5 percent range.
Today's offers might land closer to 6 percent, depending on your credit and loan type.
That sounds like a win, and sometimes it is.
But a refinance isn't free, and the savings only materialize if you stay in the home long enough to clear the closing costs.
Expect to pay 2 to 6 percent of the loan amount, which on a $350,000 mortgage can run $7,000 to $21,000.
Some lenders roll that into the new loan, which lowers your monthly bill but quietly increases what you owe.
You can also buy down the rate with upfront points, which only pays off over years, not months.
If a refinance shaves $180 off your monthly payment but costs $6,000 upfront, you need roughly 33 months just to get back to zero.
Sell or refinance again before then, and you've lost money.
Ask any lender for that break-even number in writing.
If they dodge the question, that tells you plenty.
Credit cards deserve a mention here too, because this is where refinancing gets dangerous.
Some homeowners tap their equity to wipe out card balances, trading a 22 percent interest rate for a 6 percent one.
In practice, it converts unsecured debt into debt secured by your house, and if the cards get run up again, you've put your home at risk for nothing.
When refinancing gets cheap, more buyers enter the market and competition for starter homes heats up.
Landlords also refinance, but there's no rule saying those savings reach your lease.
In many markets, rents have kept climbing regardless of what mortgage rates do.
Homeowners with credit scores above 740, at least 20 percent equity, and a plan to stay put for several years.
They'll get the best offers and the fastest break-even.
Everyone else should run the numbers before returning a single call, and compare at least three lenders, because rate quotes vary more than most people expect.
One more thing worth knowing: a refinance resets your loan clock.
If you're 12 years into a 30-year mortgage and refinance into a new 30-year term, you may lower the payment while adding years of interest back onto the back end.
A 20-year or 15-year term often makes more sense if the goal is actually paying the house off.
The closing opinion: lower advertised rates are a genuine opportunity for some households and a trap for others.
The deciding factor isn't the headline number, it's how long you'll stay and what the loan truly costs.
Final Thoughts
Do the break-even math first, then decide if the savings are real.
