Mortgage Rate Buydown: Should You Pay Discount Points?

Every time you shop for a mortgage, you'll be offered a choice: take the standard rate, or pay upfront to get a lower one. Lenders call the upfront payment "discount points" or a "rate buydown." It sounds attractive — who doesn't want a lower rate? — but whether it's actually worth it depends entirely on one calculation that most buyers skip.

What discount points are

One mortgage point equals 1% of your loan amount. On a $400,000 loan, one point costs $4,000.

Paying one point typically reduces your interest rate by approximately 0.25%, though the exact reduction varies by lender, loan type, and current market conditions. Some lenders offer a 0.20% reduction per point; others may offer 0.30%. The only way to know the exact rate reduction per point is to ask your specific lender for a rate sheet showing multiple price options.

Points are paid at closing as part of your closing costs. They are not rolled into your loan balance (unlike the VA funding fee or FHA MIP, which typically are). They come directly out of your pocket at the table.

The break-even calculation

The question "should I pay points?" has a precise mathematical answer:

Cost of points ÷ Monthly payment savings = Months to break even

Example:

• Loan amount: $400,000
• Option A: 6.75% rate, no points
• Option B: 6.50% rate, 1 point ($4,000)
• Monthly payment difference: approximately $65/month (varies by remaining term and taxes/insurance)
• Break-even: $4,000 ÷ $65 = 61.5 months (about 5 years and 1 month)

In this scenario, you need to keep the loan for more than five years before the point pays for itself. If you sell the house or refinance in year three, you lost $1,620 by paying that point.

This is the math most buyers don't do — or don't know to do. Lenders generally present the lower rate as a pure win, without emphasizing that you need to stay in the loan for a specific number of years to come out ahead.

Factors that change the break-even timeline

Higher loan amounts make points more expensive but also make the rate savings larger in dollar terms. The break-even timeline stays roughly similar.

Smaller rate reductions per point lengthen the break-even. If a point only buys you 0.125% instead of 0.25%, your break-even roughly doubles.

How long you plan to stay is the controlling variable. The national average for how long buyers keep their mortgage before selling or refinancing has historically been 7 to 10 years. But first-time buyers statistically move sooner than the average — often within five to seven years. If your break-even is 72 months and you typically move every six years, paying points is probably not worth it.

Temporary buydowns (the 2-1 buydown)

A different type of rate buydown became common during the 2022–2024 period of rising rates: the temporary buydown, often called a "2-1 buydown."

In a 2-1 buydown:

• Year 1: Your rate is 2% below the note rate (e.g., 5% if your note rate is 7%)
• Year 2: Your rate is 1% below the note rate (e.g., 6%)
• Year 3 and beyond: Full note rate applies (7%)

The cost of a 2-1 buydown is paid upfront and often comes from the seller as a concession, especially in a slower market. The seller deposits funds into an escrow account that the lender draws from each month to cover the rate reduction.

Who benefits from a 2-1 buydown: The original pitch is that it gives a buyer lower payments while they adjust their budget in the first years of ownership. The practical reality is that it's almost always more valuable to negotiate the purchase price down by the same amount the seller would spend on the buydown — a lower purchase price reduces your loan amount permanently, while a temporary buydown only helps for two years.

When sellers offer 2-1 buydowns: Sellers in a slower market sometimes offer buydowns instead of price cuts because they don't want to establish a lower comparable sale for the neighborhood. As a buyer, you can usually ask for the equivalent funds toward closing costs or simply require a lower price instead.

Permanent vs. temporary buydowns

When paying points makes sense

Paying discount points is most likely to benefit you when:

You have a long time horizon. If you're confident you'll stay in the home for eight or more years without refinancing, the accumulated monthly savings start to significantly outpace the upfront cost.

Rates have come down from a recent peak and you don't expect them to drop further. If you believe you're near the rate floor and won't have a reason to refinance, locking in the lowest possible rate with points makes more sense.

You have the cash available without depleting your reserves. Points make sense as an investment only if paying them doesn't leave you without an emergency fund. Spending down your liquidity to save $70 per month is not a good trade if your car breaks down six months later.

The tax treatment is relevant to your situation. Discount points on a purchase loan are generally deductible in the year paid for buyers who itemize. This reduces the effective cost of the points. (Points on a refinance are usually deductible only over the life of the loan, not all at once.) Consult a tax professional for your specific situation.

When to skip points

Skip paying discount points when:

• Your break-even calculation exceeds five years and you're a first-time buyer who may move within that window
• You're in a high-rate environment where refinancing is likely once rates fall — buying points on a loan you'll refinance in two years is wasted money
• You're close to your cash reserves after down payment and closing costs
• The rate reduction per point is modest (below 0.20%)

What to do before deciding

The process for evaluating points correctly:

1. Get a Loan Estimate that includes at least two rate options — the base rate with no points, and the rate with one point (or with multiple point options if the lender provides them).
2. Calculate the exact monthly savings between the two options using an amortization calculator.
3. Divide the cost of points by the monthly savings.
4. Ask yourself honestly: how likely am I to still have this loan at the break-even date?

Lenders sometimes bundle the conversation about points into an overwhelming closing cost discussion where the individual decisions get blurry. Having a written comparison in front of you — with the break-even calculated for each option — gives you something to think through clearly rather than deciding under pressure.

The Mortgage Worksheet at firsthometoolkit.com includes a dedicated discount points section that walks through this break-even math for up to three rate options simultaneously, so you can see the upfront cost, monthly savings, and break-even month all on one page before you make the call.
