Mortgage lenders love to present the "buy down your rate" option as an easy win: pay a little extra upfront, lock in a lower interest rate, and save thousands over the life of the loan.
But that pitch only works if you stay in the house long enough to break even — and a lot of buyers never run that number.
One discount point costs 1% of your loan amount and typically shaves about 0.25% off your interest rate.
On a $400,000 mortgage, that's $4,000 upfront for a rate that might drop from 6.75% to 6.5%.
Your monthly payment falls by roughly $63.
Divide the $4,000 by $63 and you get a break-even point of about 63 months — a little over five years.
That break-even window is the whole ballgame.
Sell, refinance, or move before then, and you handed the lender free money.
With the average American homeowner staying in a home around 10 to 13 years, buying points often pencils out — but averages don't pay your bills.
Your job, your family, and your local market matter more than any national statistic.
There's also a cash-flow question people skip.
That $4,000 could sit in a high-yield savings account earning around 4% to 5%, or pay down a credit card charging 22%.
Paying points makes sense only if the mortgage rate you're reducing is higher than what that same money could earn or save elsewhere.
For many buyers carrying card balances, the math flips fast.
No-points loans keep things simple: lower closing costs, more cash left in your pocket on move-in day, and a slightly higher monthly payment.
That flexibility is worth real money if you expect to relocate for work, upgrade within a few years, or just want a cushion for the unexpected — a new roof, a job change, a medical bill.
Ask your lender for a loan estimate showing both scenarios side by side, with the break-even month spelled out in writing.
Compare at least three lenders, because point pricing varies more than most people expect.
And if you're using a down payment assistance program, check whether paying points is even allowed or whether that cash is better spent lowering your down payment.
In a slow market, some sellers will cover discount points as a concession to close the deal.
That's the rare case where you get the lower rate without spending your own savings — worth asking for, especially if the home has sat on the market for a while.
The bottom line is that points aren't a scam or a slam dunk.
They're a bet on how long you'll stay put, and you're the only one who can honestly make that call.
Run your own break-even number before you sign anything, not the one a loan officer sketches on a napkin.
If you can't confidently say you'll be in the house past that month, keep your cash and take the higher rate.
Final Thoughts
Flexibility has a price too — and it's usually cheaper than a bet you lose.
