Walk into any mortgage closing and you'll face a quiet fork in the road: write a bigger check up front for a lower rate, or keep that cash and accept a higher one.
Consumer advocates call it one of the most misunderstood line items on a loan estimate.
One discount point typically costs 1% of your loan amount and shaves roughly 0.25% off your interest rate, though the exact trade varies by lender and day.
On a $400,000 mortgage, that's $4,000 upfront to drop from, say, 6.75% to 6.5%.
The math only works if you stay put long enough.
Divide the upfront cost by the monthly savings to get your break-even point.
In that example, you'd save about $63 a month, so it takes roughly 63 months — a little over five years — just to get your money back.
Sell, refinance, or get transferred before then, and you've handed the lender a gift.
The average American homeowner now stays in a home about a decade, according to industry data, which sounds like plenty of runway.
So do people who bought at the top of their budget and later need more space.
There's also an opportunity cost nobody puts on the closing disclosure.
That $4,000 could sit in a high-yield savings account, pay down a credit card, or cover a home repair.
Comparing a point buy to a 4%-plus savings rate is a fairer fight than comparing it to zero.
If you're certain you'll stay 10 or 15 years and you have cash you won't miss, buying the rate down is a reasonable, low-drama move.
It's essentially prepaying interest for a guaranteed return — and a guaranteed return is rare.
Some loan officers quote a "no points" rate and a "with points" rate side by side, then nudge you toward the lower number without mentioning how long it takes to pay off.
Others quietly build points into a rate quote and call it standard.
Always ask for the loan estimate both ways, in writing.
Also check whether your lender offers a temporary buydown instead.
A 2-1 buydown lowers your rate for the first two years and can be funded partly by the seller in a slow market.
It's a different tool with different math, but in a high-rate environment it's often the easier pill to swallow — especially if you expect rates to fall and plan to refinance anyway.
One more wrinkle: if you itemize, points on a first mortgage are generally deductible in the year you pay them, which softens the upfront hit.
Most filers take the standard deduction, though, so don't count on it.
Bottom line: points are a bet on staying put.
Run your own break-even number, ask what the money would earn elsewhere, and get every quote in writing before you commit. **Our take:** Buying points isn't a scam, but it's frequently oversold to buyers who won't stick around long enough to win.
Final Thoughts
If your break-even lands beyond five years and your life isn't nailed down, keep the cash.
