Mortgage rates have been bouncing around in the low-to-mid 6% range for a 30-year fixed loan, and that number is doing a lot of work on buyers' nerves.
So when a lender slides a "buy down your rate" option across the table, it can feel like the obvious move.
Pay a little extra now, get a smaller payment for the next 30 years.
That upfront fee is called discount points, and one point costs 1% of your loan amount.
On a $400,000 mortgage, one point runs $4,000.
Paying it typically knocks your interest rate down by about 0.25%, though the exact discount varies by lender and changes with the market almost daily.
That lower rate doesn't pay you back immediately — it pays you back over time.
The break-even point is the number of months it takes for your monthly savings to equal what you paid upfront.
On a $400,000 loan, dropping from 6.5% to 6.25% saves roughly $60 a month.
Divide $4,000 by $60, and you're looking at about 67 months, or five and a half years, before you're actually ahead.
If you sell, refinance, or move before you hit break-even, you handed the lender thousands of dollars for nothing.
And life has a way of ignoring your five-year plan.
A new job, a growing family, or a refinance when rates finally drop can all wipe out your savings overnight.
There's a second trap nobody mentions at the closing table: points are paid from your cash reserves.
Every dollar you sink into a rate buy-down is a dollar you can't use for a down payment, an emergency fund, or the new roof you'll probably need in year three.
A slightly higher rate with more cash in the bank is often the safer bet, especially for first-time buyers.
So when does buying points actually make sense?
When you're genuinely planning to stay put for the long haul, when you have plenty of cash left over after closing, and when the break-even period comes in comfortably under how long you expect to keep the loan.
Some buyers also use a temporary buy-down — where the rate is reduced for the first two or three years and then steps up — which can help if your income is set to rise.
The smartest move is to ask your lender for both scenarios in writing.
Get the monthly payment with points and without, the total upfront cost, and the exact break-even month.
Then compare that to a no-points loan from at least two other lenders.
Rates and point costs vary enough between them that shopping around often saves more than paying points ever would.
Our take: points are a tool, not a default.
For most buyers who aren't certain they'll stay put past five or six years, keeping that cash and taking the slightly higher rate is the more flexible, less regret-prone choice.
Final Thoughts
Run your own break-even number before you sign — your future self will thank you.
