Two homebuyers in the same neighborhood, same loan amount, same day.
Over the next few years, their monthly payments look almost identical, but their bank accounts tell a very different story.
That check is the mortgage point, and it's one of the most misunderstood line items in American homebuying.
One discount point costs 1% of your loan amount.
On a $400,000 mortgage, that's $4,000 paid upfront to shave your interest rate, usually by about 0.25 percentage points.
The trade is simple on paper: pay now, save later.
On that $400,000 loan, one point might drop your rate from 6.5% to 6.25%.
Your monthly principal and interest payment falls from roughly $2,528 to about $2,463.
Divide your $4,000 by $780 and you get a break-even point of just over five years.
If you plan to stay put longer than that, the math tilts your way.
Sell or refinance before then, and you've essentially donated that money to the lender.
This is the single biggest mistake buyers make with points: paying for them on a starter home they'll outgrow in three years.
Some borrowers take the opposite deal, accepting a slightly higher rate in exchange for lender credits that cover closing costs.
If cash is tight, that trade can matter more than a lower payment decades from now, because it keeps money in your pocket when you actually need it.
Ask yourself three questions: How long will I realistically keep this loan?
Do I have the cash without draining my emergency fund?
And would I rather have a lower monthly bill or a lower upfront cost?
Points on a primary residence are generally tax-deductible in the year you pay them, but the rules have limits and exceptions, so check with a tax professional.
Points on a refinance usually get deducted over the life of the loan instead.
Also, don't confuse discount points with origination points.
Origination points are lender fees for processing the loan.
Some lenders blur the language on purpose, so read the loan estimate line by line and ask which charges actually lower your interest rate.
Shopping three lenders on rate alone tells you almost nothing.
What matters is the annual percentage rate, which bundles rate, points, and fees into one number.
A lender advertising a flashy low rate might be charging two points to get there, which can make the deal worse than a slightly higher rate with no points.
If you're deciding right now, run the break-even math yourself.
Divide the total cost of the points by the monthly savings.
If the answer is longer than you expect to own the home, skip the points and keep your cash.
The mortgage industry loves to sell points as a smart move, and sometimes they are.
But "smart" depends entirely on your timeline, not the lender's pitch.
Final Thoughts
Run the numbers for your own situation, and treat any deal that only works if you stay put forever with real suspicion.
