What Are Discount Points in Real Estate and How Do They Work?

Discount points in real estate are an upfront fee you pay your lender at closing to permanently lower the interest rate on your mortgage.¹ One point costs 1% of the loan amount and usually shaves about 0.25 percentage points off your rate, though the exact reduction varies by lender and market. Whether points are worth buying comes down to a single question: will you keep the loan long enough to earn back what you paid?

Points are voluntary. You choose whether to buy them, and how many, based on your cash at closing, how long you expect to stay in the home, and what the tax treatment looks like for your situation. Origination points are a separate charge for processing the loan and do not lower your rate, so don’t confuse the two when you review your paperwork.²

What One Point Costs and How Much It Saves

One discount point equals 1% of your total loan amount.² On a $300,000 mortgage, that’s $3,000. On a $500,000 loan, one point is $5,000. Many lenders let you buy fractional points too, so half a point on that $300,000 loan would cost $1,500 and drop the rate by roughly 0.125 percentage points.

To see how the trade-off works in practice, here is a $300,000, 30-year fixed-rate mortgage at three different price points:

No points at 6.5%: about $1,896 per month in principal and interest
One point ($3,000) at 6.25%: about $1,847 per month
Two points ($6,000) at 6.0%: about $1,799 per month

Buying one point saves roughly $49 a month. Over the full 30 years, that adds up to about $17,600 in interest savings against the $3,000 upfront cost. The savings are real, but only if you actually keep the loan.

Should You Buy Points? The Break-Even Test

The core math is simple: divide the upfront cost of the points by the monthly savings. In the example above, $3,000 divided by $49 comes to about 61 months, or roughly five years. Sell, refinance, or pay off the loan before then and you lose money on the deal. Stay in the loan past that point and every month is savings in your pocket.

A break-even of two to three years is generally considered favorable. Anything beyond seven or eight years deserves closer scrutiny. Before you commit, weigh a few things:

How long you realistically expect to stay in the home. A move within a few years usually kills the math.
Where rates are heading. If rates are drifting down, you may refinance before recouping the cost.
What else the cash could do. Money spent on points can’t go toward a larger down payment, reserves, home repairs, or investments that might earn a better return.

Lender Credits Work the Other Direction

Lender credits are the mirror image of discount points, sometimes called negative points. The lender covers part of your closing costs and you accept a higher interest rate in return.² They can help if cash at closing is tight or if you don’t plan to keep the mortgage long. The more credits you take, the higher your rate. When you compare offers, look past the closing-day number and total up what you’ll pay across the years you expect to hold the loan.

Points on an Adjustable-Rate Mortgage

On an ARM, points only reduce the rate during the initial fixed period, typically three, five, seven, or ten years. Once the rate adjusts, the discount is gone. That shortens the window to recoup your upfront cost and generally makes points a tougher call on adjustable loans than on fixed ones.

Seller-Paid Points

Sellers sometimes agree to pay for discount points as a concession, which is more common in buyer-friendly markets. For conventional loans backed by Fannie Mae, how much a seller can contribute depends on the loan-to-value ratio:³

Down payment above 25% (LTV 75% or less): up to 9% of the sale price
Down payment between 10% and 25% (LTV 75.01%–90%): up to 6%
Down payment below 10% (LTV above 90%): up to 3%

These caps apply to total financing concessions, not points alone. FHA loans generally allow seller concessions up to 6% of the purchase price, and VA loans typically cap them at 4%.

For tax purposes, the IRS treats seller-paid points as if you paid them. You can deduct them in the year of purchase if you meet the standard tests, but you must reduce your home’s cost basis by the same amount.⁴ That smaller basis can slightly increase any taxable gain when you eventually sell.

How Discount Points Are Taxed

The IRS treats discount points as prepaid mortgage interest.¹ Whether you can write them off, and how quickly, depends on the property, the loan type, and whether you itemize.

You Have to Itemize

Points are deductible only if you itemize on Schedule A.¹ For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.⁵ If your itemized deductions don’t exceed those thresholds, the points deduction won’t help you.

The Nine Tests for a Same-Year Deduction

Points on a purchase mortgage for your primary residence can be deducted in full the year you pay them, but only if you meet all nine of these IRS tests:⁶

The loan is secured by your main home.
Paying points is an established business practice in your area.
The points don’t exceed what’s generally charged in your area.
You use the cash method of accounting (most individuals do).
The points weren’t charged in place of other fees like appraisal, title, or attorney costs.
The cash you brought to closing, including down payment and earnest money, was at least equal to the points charged, and you didn’t borrow those funds from the lender.
The loan was used to buy or build your main home.
The points were calculated as a percentage of the loan principal.
The points are clearly shown on your settlement statement.

Fail any single test and you have to spread the deduction evenly over the life of the loan. On a 30-year mortgage, that’s one-thirtieth of the total each year.

The $750,000 Debt Cap

Mortgage interest, including points, is deductible only on the first $750,000 of acquisition debt ($375,000 if married filing separately) for loans taken out after December 15, 2017.⁷ The cap originated in the Tax Cuts and Jobs Act and was made permanent in 2025. If your loan is larger, only a proportional share of your points is deductible. Loans taken out on or before December 15, 2017 still use the older $1,000,000 limit.

Refinance Points

Points paid on a refinance generally can’t be deducted all at once. You spread them evenly over the term of the new loan.¹ Pay $3,000 in points on a 30-year refinance and you deduct $100 a year.

There is one useful exception. If you refinance again or pay off the loan early with a different lender, you can deduct any remaining unamortized points from the earlier refinance in the year the old loan ends. Refinance with the same lender and those remaining points have to be spread over the new loan instead.

Second Homes and Investment Property

Same-year deduction is reserved for your primary residence. Points on a second home or vacation property must be spread over the life of the loan even if every other test is met.¹ Points on loans for investment or rental property follow the same ratable rule.

Where Points Show Up on Your Loan Paperwork

Your Loan Estimate arrives within three business days of your application and shows the projected rate along with any cost tied to buying points, so you can weigh the upfront expense against the rate reduction before committing.⁸ By law, anything labeled as points on these disclosures must be connected to a discounted rate.²

You receive the Closing Disclosure at least three business days before signing.⁸ It lists the exact cost of any points you’re buying. Compare it against the Loan Estimate line by line. If anything has changed, ask your loan officer to explain before you sign. Once you close, the lower rate is locked in for the life of the loan.
