Mortgage Points: When Buying Down Your Rate Actually Pays Off

Paying points is worth it when you keep the loan long enough to earn the money back – and not a day sooner. That is the whole answer. The work is figuring out your break-even month and being honest about whether you will still have the loan when it arrives.

What are mortgage points?

A discount point is prepaid interest. You hand the lender money at closing, and in exchange the lender lowers the interest rate on your note for the life of the loan. One point equals 1% of the loan amount – not the purchase price, which trips up plenty of first-time buyers. On a $400,000 loan, one point is $4,000, due at closing alongside your down payment and the rest of your costs.

Points are quoted in fractions as often as whole numbers. Half a point on that same loan is $2,000. And how much rate a point buys is not fixed – it moves with the bond market, the loan program, your credit, and your loan-to-value. Some days a point buys a quarter percent. Other days the same point buys noticeably less. That is why we price the buydown on the day you lock rather than from a rule of thumb.

Do not confuse discount points with an origination point, which is a fee for making the loan and buys you nothing in rate. They can appear on the same page of a Loan Estimate. Ask which is which.

How to calculate your break-even on points

Two numbers, one division:

Cost of the points ÷ monthly payment savings = months to break even.

Here is the math on a $400,000, 30-year fixed loan. These figures are illustrative examples only, not a quote or an offer – actual rates and pricing change daily and depend on your file.

One point saves about $65 a month in this example. Divide $4,000 by $65 and you get roughly 61 months – a little over five years – before the buydown has paid for itself. Everything after month 61 is savings you keep. Sell in year three, and you spent $4,000 to save about $2,350.

Notice the bottom row. The lender credit runs the same math backwards: you take a higher rate, the lender pays $4,000 toward your closing costs, and the higher payment “repays” that credit in roughly the same five years. Neither direction is a trick. They are the same lever pulled two ways.

When paying points usually makes sense

• You are staying put. A forever home in Gilbert or Queen Creek that you plan to hold for a decade clears a five-year break-even easily.
• You have cash beyond a comfortable reserve. Points should never come out of the emergency fund or the money that would have lowered your loan-to-value below a pricing tier.
• Someone else is paying. Seller concessions and builder incentives frequently fund a buydown. When the credit is not your money, the break-even question mostly disappears.
• The lower payment changes your approval. A smaller payment means a lower debt-to-income ratio, which occasionally is what makes a file work at all.

When to skip them

• You expect to move or refinance inside the break-even window. A job change, a growing family, or a rate outlook you plan to act on all shorten the clock.
• Cash is tight. Reserves after closing matter to underwriting and to your peace of mind. A lender credit may serve you better than a buydown here.
• The dollars work harder elsewhere. More down payment can drop your loan-to-value into better pricing or remove mortgage insurance, which sometimes beats the buydown outright.
• You are already at the edge of a pricing tier. Small changes in credit score or down payment can move your rate without buying a single point.

Permanent buydown vs. temporary buydown

Discount points buy the note rate down permanently. A temporary buydown – the 2-1 and 1-0 structures that got popular when rates climbed – is a different animal. Money goes into an escrow account and subsidizes your payment for the first year or two, then the payment steps up to the real note rate. Your note rate never changed; only the payment did, and only for a while.

Temporary buydowns are usually funded by a seller or builder as a concession. They can be a genuinely good deal on a new build in the East Valley. Just underwrite yourself at the full note rate, because that is the payment you own in year three. Any lender worth using underwrites you at that rate anyway.

How to decide, step by step

1. Get the same loan quoted with and without pointsSame loan amount, same day, same program. Compare the rate and the total closing costs side by side, and read the Loan Estimate rather than a text message.
2. Do the divisionCost of the points divided by the monthly savings gives you the break-even month. Write the number down.
3. Name your realistic horizonHow long will you actually keep this loan – not this house? A refinance resets the clock and ends the payoff on the points you bought.
4. Compare against the alternativesPut the same dollars toward a larger down payment or reserves and see which produces the better outcome for your file.
5. Lock the pricing you decided onWhat a point buys moves daily. Once the numbers make sense, lock so the decision you made is the decision you get.

Key terms

Discount point

Prepaid interest equal to 1% of the loan amount, paid at closing to permanently lower the note rate.

Origination point

A fee charged for making the loan. Same 1% math, but it buys no rate reduction.

Break-even month

Cost of the points divided by the monthly payment savings – the month the buydown starts paying you.

Lender credit

The reverse of points: you accept a higher rate and the lender contributes toward your closing costs.

Temporary buydown

Escrowed funds that reduce the payment for the first year or two, often seller-paid, before it steps to the full note rate.

Note rate

The actual interest rate on your promissory note, as distinct from the APR or a temporarily subsidized payment.
