Mortgage refinance applications jumped sharply this spring, according to the Mortgage Bankers Association, as the average 30-year fixed rate dipped below 6.5% for the first time in months.
Lenders are advertising hard, mailers are piling up, and every financial site has a calculator telling you to act now.
Before you call the number on that postcard, it's worth asking who actually benefits from your refi.
Advertised figures usually assume a 780 credit score, a 20% down payment, and zero cash-out.
Add a second mortgage, a recent late payment, or a condo with a high HOA, and the pricing adjusters stack up fast.
Closing costs typically run 2% to 6% of the loan amount, which on a $350,000 balance means somewhere between $7,000 and $21,000.
Some of that can be rolled into the new loan, but rolling it in means paying interest on your closing costs for 30 years.
The break-even math is the only math that matters.
Divide your total closing costs by your monthly savings.
If refinancing costs $9,000 and saves you $150 a month, you need 60 months, five full years, just to get back to even.
If you might sell, relocate, or refinance again before then, you're likely handing money to the lender for nothing.
Plenty of homeowners who refinanced in 2020 and 2021 are now sitting on loans they won't recoup for years.
It sounds like free money, but the bank recovers those costs through a higher interest rate.
You're not avoiding the expense, you're financing it quietly over the life of the loan.
Cash-out refinances carry their own trap: you're trading a low-rate first mortgage for a bigger one at today's rate, and if you're pulling equity to pay off credit cards, you've converted unsecured debt into debt secured by your home.
Miss those payments and the stakes are much higher than a collections call.
The people pushing hardest have the most to gain.
Loan officers earn commission on volume, and refi booms are their busy season.
Servicers often sell your new loan within weeks, so the relationship you think you're building may not exist by the time you make your third payment.
Meanwhile, the same rate headlines that drive clicks drive applications, whether or not the numbers work for you specifically.
Pull your actual mortgage statement and your credit score, then get quotes from at least three lenders, including a credit union and an online broker.
Ask for a Loan Estimate, not a verbal quote, and compare the total cost over the time you genuinely expect to stay in the home.
If you can't answer how long that is, you're not ready to refinance.
A lower rate is not the same as a better deal, and a busy lender is not a charity.
Run your own break-even number before anyone runs it for you.
Final Thoughts
If the math only works when you squint, the refi is probably working for the bank, not for you.
