Mortgage lenders love to pitch the "buy down your rate" option at the closing table, and it sounds responsible: pay a little extra now, save a lot later.
But that upfront fee, known as discount points, only pays off under specific conditions, and plenty of buyers never run the numbers before signing.
One discount point costs 1% of your loan amount and typically shaves 0.25% off your interest rate.
On a $400,000 mortgage, that's $4,000 upfront to drop from, say, 6.75% to 6.5%.
Divide $4,000 by $63 and you get about 63 months — a little over five years — before you break even.
That breakeven window is the whole ballgame.
If you sell, refinance, or pay off the loan before you hit it, you handed the lender money for nothing.
The average American homeowner stays in a home about eight years, but that's an average, and averages don't pay your bills.
If a job offer, a growing family, or a divorce could move you in three years, paying points is a donation.
Points make the most sense in a few narrow situations.
You plan to stay put for the long haul, you have cash beyond your down payment and emergency fund, and you're already comfortable with the payment.
In that case, buying the rate down is a decent, low-risk move.
Some buyers also use seller credits to cover points, which flips the math entirely — that's free savings if you negotiate it.
There's a second wrinkle: paying points only wins if you'd otherwise keep that cash idle.
If the $4,000 would go toward high-interest credit card debt at 22%, paying down the card beats buying down the mortgage almost every time.
Run both scenarios side by side instead of letting a loan officer frame it for you.
Points on a mortgage used to buy or build your primary home are generally deductible in the year you pay them, but rules and your standard deduction matter.
Don't buy points just for a write-off — that's backwards.
One more trap: "no points" doesn't mean "no fees." Lenders still charge origination, appraisal, title, and closing costs.
Compare the annual percentage rate, not just the headline rate, because the APR folds those fees in.
A no-points loan with a fat origination fee can cost more than a points loan with leaner costs.
Ask for a loan estimate from at least three lenders on the same day, with the same loan amount and term.
Then ask each one for two versions: with points and without.
The difference in monthly payment and total cost over your realistic timeline will make the decision obvious. **Our take:** Discount points aren't a scam, but they're oversold to buyers who won't stick around long enough to benefit.
Final Thoughts
Treat the breakeven month as a hard deadline, not a suggestion, and only buy points with money you truly won't miss.
