Thirty-year mortgage rates have drifted down from their recent peaks, and every lender in America has noticed.
The result is a flood of refinance advertising promising to slash monthly payments, with slick calculators that assume you'll stay in the house forever and pay zero closing costs.
Those assumptions are doing a lot of heavy lifting.
Here's the part the ads skip: a refinance only pays off if you stay put long enough to recoup the fees.
Closing costs typically run 2% to 6% of the loan balance, according to consumer finance data.
On a $350,000 mortgage, that's $7,000 to $21,000, either paid upfront or quietly rolled into your new balance.
Divide those costs by your monthly savings, and you get your break-even point.
If it's 30 months and you might move in two years, the math doesn't work no matter how good the rate looks.
The break-even trap catches more people than you'd think.
Lenders love the "no-cost" refinance because it usually means a higher interest rate in exchange for covering fees.
You save immediately, but you pay more every month for years.
Whether that's a good deal depends entirely on how long you keep the loan, and nobody hands you a crystal ball at closing.
A slightly lower rate you pay for upfront can beat a "free" refinance over a decade, but the free version wins if life moves fast.
Pulling cash out during a refinance has become popular again as home values sit near record highs.
That's not free money; it's converting equity into debt secured by your house.
If prices dip in your local market afterward, you can end up owing more than the home is worth, which makes selling or refinancing again much harder.
Lenders profit from the loan volume either way.
Stretching a remaining 22 years back out to 30 years lowers the payment but can add years of interest and thousands in total cost.
A shorter term raises the payment, which defeats the purpose for many households.
The honest move is to compare your current loan's remaining schedule against the new one, not just the headline rate.
If you're serious about refinancing, shop at least three lenders, including a credit union, and ask for the Loan Estimate form on the same day from each.
That form makes fees comparable in a way quotes over the phone never do.
Also check whether your existing loan has a prepayment penalty, and confirm your credit score before anyone pulls it, since a few points can change your rate tier.
A refinance can be a genuinely good financial move in the right situation.
It can also be an expensive way to feel like you did something.
Final Thoughts
Run the break-even number first, and if a lender won't help you calculate it plainly, that tells you plenty.
