Walk into any mortgage lender's office and you'll get a menu of rates, each paired with a number called "points." Pay more upfront, get a lower rate.
It sounds like a simple trade-off, and that's exactly the problem — the simplicity is doing a lot of hidden work.
On a $400,000 mortgage, one point costs $4,000 and typically shaves somewhere between 0.25% and 0.5% off your interest rate.
Lenders love talking about the lower monthly payment, because that's the number you feel every month.
They're much quieter about the break-even point — the month when your upfront cash finally outweighs the savings you've collected.
If you pay $4,000 to save $150 a month, you need 27 months just to get your money back.
Sell, refinance, or move before then, and you handed the lender a gift.
The average American homeowner stays in a home about eight to ten years, but a large chunk of buyers move or refinance far sooner — and those people are the ones who make points profitable for the industry.
The math also flips depending on where rates are headed.
If you buy down your rate and rates fall two years later, you refinance at the new low rate and your original points evaporate.
You paid for a discount you no longer needed.
Lenders know this pattern well; it's not a secret, it's just not the headline.
Buyers with cash sitting idle, a firm plan to stay put for at least five to seven years, and no realistic refinance on the horizon.
If you're stretching to cover the down payment, points are almost certainly the wrong move — you'd be borrowing from your safety net to subsidize a monthly bill.
The no-points route isn't automatically smarter, either.
You'll pay a higher rate for the life of the loan, and if you never refinance, that adds up.
The honest answer is that neither option is "best." The right one depends on a timeline you can't fully predict, which is why lenders can sell either version with a straight face.
Ask for the loan estimate in writing and compare the total cost over five, seven, and ten years — not just the monthly payment.
Run the break-even yourself, or ask a fee-only advisor to do it.
And be skeptical of anyone who tells you points are "free money" or that no-points loans are "for suckers." Both pitches exist to move you along. **The takeaway:** Points are a bet on your own future, and the house usually knows the odds better than you do.
If a lender pushes hard in either direction without asking how long you plan to stay, that's your signal to slow down.
Final Thoughts
The lowest rate on the menu is rarely the cheapest loan in the end.
