Buydown vs Discount Points: The Real Cost Difference

Both a mortgage buydown and discount points let you pay upfront to lower your mortgage rate. They sound like the same thing, and lenders sometimes use the terms interchangeably, but they work completely differently. Pick the wrong one and you can leave thousands of dollars on the table.

What the two strategies share

Both a temporary buydown and discount points involve paying an upfront fee at closing in exchange for a lower interest rate and a lower monthly payment. Both can be paid by the seller as a concession. Both are quoted in "points" — 1 point = 1% of the loan amount. That is where the similarities end.

The one difference that matters

Discount points permanently lower your rate for the entire life of the loan. Pay 1 point, drop your rate from 6.5% to 6.25%, and you keep that 6.25% for all 30 years — or until you sell or refinance.

A temporary buydown lowers your rate only for the first 1-3 years. A 2-1 buydown drops your rate 2 points in year 1 and 1 point in year 2, then the rate snaps back to the note rate (6.5%) for the remaining 28 years.

Worked example on a $400,000 loan

Suppose you are taking out a $400,000 30-year fixed mortgage at a 6.5% note rate. You have two options: pay 1 discount point ($4,000) to permanently lower the rate to 6.25%, or take a 2-1 buydown (funded by the seller) that drops the rate to 4.5% in year 1 and 5.5% in year 2 before returning to 6.5%.

The buydown delivers much bigger savings in years 1-2 ($501/month and $257/month respectively, versus $65/month with points), but then the payment jumps above the points payment for the remaining 28 years. The points deal pays $65/month less forever.

Break-even comparison

For the points deal, the break-even is simple: you paid $4,000 upfront to save $65/month, so break-even is $4,000 ÷ $65 = ~61 months (about 5 years). After 5 years, every month you keep the loan is pure savings.

For the buydown, there is no break-even to calculate from the borrower's perspective — the seller paid for it. The real comparison is cumulative savings over time. Let's add it up:

• After 2 years: Buydown saves ~$9,097; points save ~$1,560 (and cost $4,000 upfront, so net -$2,440). Buydown crushes points.
• After 5 years: Buydown has saved ~$9,097 total (the buydown period is over). Points have saved ~$3,920 net of cost. Buydown still ahead.
• After 10 years: Buydown still ~$9,097. Points have saved ~$7,820 net. Buydown still ahead.
• After ~15 years: Points overtake the buydown. Points have saved ~$11,720 net; the buydown is still $9,097. From year 15 on, points win by more each year.

The crossover is around year 15. If you expect to sell or refinance before then, the buydown wins (assuming the seller pays for it). If you plan to stay 15+ years, points win — and remember, with points you paid $4,000 of your own money, so the comparison is not apples-to-apples. If you had to pay for the buydown yourself, points would win much earlier.

When discount points win

• You plan to stay long-term. If you expect to be in the home (and the loan) for 10+ years, the permanent rate reduction compounds in your favor.
• The seller will not fund a buydown. If you are paying upfront yourself, points give you a permanent benefit for the same money.
• You can deduct the cost. Points on a purchase mortgage are usually deductible in the year you pay them, which softens the upfront cost.
• Rates are not expected to fall. If you do not think you will refinance, lock in the permanent reduction.

When a buydown wins

• The seller is paying. A free buydown is always better than paying for points. The question becomes buydown vs. price reduction, not buydown vs. points.
• You need short-term payment relief.If you have high expenses in the first 1-3 years (renovations, moving costs, two mortgages), the buydown's front-loaded savings are more useful than a small permanent reduction.
• You expect to refinance within 3 years. If you think rates will drop and you will refi before the buydown expires, you capture the heavy year-1 savings and then refi out of the note rate entirely.
• You are cash-constrained at closing. Points require cash at closing; a seller-funded buydown does not.

The hybrid: buydown now, refi later

A common 2026 strategy: take a seller-funded 2-1 buydown to get through the first two years at a low rate, then refinance into a permanent lower rate when (and if) rates fall. If rates drop from 6.5% to 5.5% in year 2, you refinance, the buydown has saved you $9,000, and you never pay the 6.5% note rate at all. If rates do not drop, you are stuck with the 6.5% payment from year 3 on — which is the risk.

The key is to treat the buydown as a bridge, not a permanent solution. Run the refinance calculator with the rate you think you might get in 1-2 years to see whether a future refi would pay off.

A simple decision framework

1. Is the seller offering a free buydown? If yes, take it (or negotiate for a price reduction instead if you plan to stay 7+ years). Do not pay for a buydown yourself.
2. Are you paying yourself? If yes, buy discount points — not a temporary buydown. Use the points calculator to find the break-even.
3. Do you plan to move or refi within 3 years? A buydown (if free) is ideal. If you are paying, points with a short break-even (under 3 years) can also work.
4. Do you plan to stay 10+ years? Points win decisively. A free buydown still wins for the first 2-3 years, but then the permanent rate reduction of points pulls ahead.
