Mortgage Refinance Math Has Shifted Again This Month

Persona #2 ยท Vol: 0

The refinance conversation is back at kitchen tables across the country, and for once it isn't only about shaving a quarter point.

Lenders are advertising 30-year fixed refis in the low 6% range for well-qualified borrowers, while 15-year options are landing closer to the mid-5s.

That's still nowhere near the 3% era, but it's a real gap for anyone who bought or refinanced during the 2023 rate spike.

Here's the part most ads skip: a refinance only pays off if you plan to stay put long enough to clear the closing costs.

Those costs typically run 2% to 5% of the loan balance, which on a $350,000 mortgage means somewhere between $7,000 and $17,500.

If you sell or refinance again in two years, you may hand back every dollar you saved.

Do the break-even math before you call anyone.

Divide your total closing costs by your monthly savings.

If the answer is 30 months and you expect to move in three years, the deal is thin.

If it's 14 months and this is your forever house, the math gets a lot friendlier.

Cash-out refinances are a different animal and deserve extra caution.

Trading a sub-4% mortgage for a 6.5% loan to fund a kitchen remodel or pay off credit cards can cost six figures in extra interest over the life of the loan.

Credit card debt at 22% is brutal, but rolling it into a 30-year mortgage stretches that debt across three decades.

Origination charges, appraisal fees, title insurance, and recording fees all add up, and some lenders pad them with discount points you didn't ask for.

Ask for a Loan Estimate from at least three lenders on the same day, then compare line by line, not just the headline rate.

Your credit score moves the needle more than most people realize.

Borrowers with scores above 740 tend to get the best advertised pricing, while a score in the 640s can add close to a full percentage point.

Paying down a card balance or disputing an old error can be worth more than shopping around for weeks.

One more thing worth checking: assumable loans and lender-specific programs.

Some government-backed mortgages can be taken over by a buyer, which is a selling point in a slow market.

A few credit unions also run refi specials for existing members with no origination fee, and those rarely show up in national rate tables.

The honest takeaway is that refinancing is a math problem, not a mood.

Run your break-even number, get three written estimates, and ignore anyone who promises savings without seeing your actual loan documents.

Final Thoughts

If the numbers work, great, but walking away is a perfectly good outcome too.
