How to Buy Down Your Mortgage Interest Rate

Purchasing mortgage points to reduce your interest rate can save you tens of thousands over the life of your loan but means more cash out of pocket at closing.

As interest rates hovered around 6.36% with the 30-year fixed-rate mortgage on May 14,2026 and the median monthly mortgage payment at all-time high of $2,131 in March 2026 according to Mortgage Bankers Association, this substantial decline can mean a substantial financial difference even when only a little is mitigated.

This guide walks through exactly how mortgage rate buydowns work, what they cost, and how to figure out if one makes sense for your situation.

Key Takeaways

• Each discount point costs 1% of your loan amount and typically reduces your rate by 0.25%.
• On a $400,000 loan, buying two points ($8,000 upfront) at 6.5% cuts your monthly payment by $133 and saves $47,858 in total interest over 30 years — if you stay the full term.
• The break-even point on points is typically 5–7 years — if you plan to move or refinance before then, buying down the interest rate on your mortgage is unlikely to pay off.
• Points paid on a primary residence purchase are generally fully deductible in the year paid; refinance points must be amortized over the loan term.
• In a potentially falling rate environment like 2026, locking in points requires careful consideration — refinancing before break-even eliminates the savings.

What Is a Mortgage Rate Buydown?

A rate buydown is when costs are paid upfront at closing that provides a lower interest rate on the mortgage. For people owning their home, to get a lower interest rate on their mortgage, mortgage points, also referred to as discount points are sold. Each point costs 1% of the loan amount and generally reduces interest rate by about 0.125% to 0.25% contingent on the lender and market rates. According to Consumer Financial Protection Bureau, 1-point corresponds to a 1% deduction of loan amount, and generally trades off interest rate by 0.125% to 0.25%.

Think of it as prepaying interest. You give the lender cash today, and they charge you less interest for the life of the loan — or in some cases, for a temporary period.

Example: On a $400,000 loan at a 6.5% interest rate, one discount point costs $4,000. Buying that point typically reduces your rate to approximately 6.25%, lowering your monthly payment and reducing the total interest you pay over 30 years.

Most lenders list their rates both with and without points. This is especially useful context for first-time home buyers comparing loan options — always ask your loan officer to show you both so you can compare the true cost before deciding whether to buy down your mortgage interest rate.

How Does a Rate Buydown Work?

When you buy points, you are essentially paying the lender to accept less interest income over the life of your loan. The process works like this:

1. Your lender quotes you a base interest rate — for example, 6.36% on a 30-year fixed mortgage as of May 2026 (Freddie Mac)
2. You choose to pay one or more discount points at closing
3. Each point (1% of the loan amount) reduces your rate, typically by 0.25%
4. Your new lower rate begins immediately and stays locked in for the life of the loan

The exact reduction per point varies by lender and changes with market conditions. Some lenders offer 0.125% per point; others offer up to 0.375%. Always get specific quotes in writing before deciding.

Types of Mortgage Rate Buydowns

Permanent Buydowns

A permanent buydown reduces your interest rate for the entire loan term. You pay points at closing, and your lower rate stays locked in for as long as you hold the mortgage. This is the most common way to buy down your mortgage interest rate. Most lenders allow you to purchase between one and four points.

Temporary Buydowns

With a temporary buydown, your rate starts lower but rises over time until it reaches the full contract rate. These are most commonly offered by home builders and sellers as closing incentives — meaning the seller or builder pays the buydown cost, not you.

2-1 Buydown

Rate is 2 points below contract in year one, 1 point below in year two, then full rate from year three on. On a 6.5% mortgage: 4.5% → 5.5% → 6.5%.

3-2-1 Buydown

Your rate will be reduced by 3 points during year 1, 2 points during year 2, 1 point during year 3 and then go back to the normal rate. On a 6.5% mortgage: 3.5% in year one, 4.5% in year two, 5.5% in year three, then 6.5% for the remaining 27 years.

1-0 Buydown

Your rate is 1 percentage point lower in year one only, then rises to the full rate. The simplest and least expensive temporary option.

Lender-Paid Buydowns

A lender-paid buydownm the lender pays the points, but charges you a slightly higher interest rate. This can help minimize your closing cash needs, albeit at the expense of additional interest paid over time. Be sure to figure out the overall expense of each buydown option before agreeing to one that has been offered by a lender.

How Much Does It Cost to Buy Down Your Interest Rate on a Mortgage?

The cost depends entirely on your loan amount and how much you want to drop your rate. Standard industry figures from Bankrate and the Consumer Financial Protection Bureau break it down like this:

• One point = 1% of your loan amount
• Rate reduction = typically 0.25% per point (range: 0.125%–0.375% depending on lender)
• Maximum points = most lenders cap at 3–4 points
• Closing costs = points are paid at closing alongside other costs, which typically total 2–5% of the loan amount

Break-Even Comparison Table (30-Year Fixed, 6.5% Base Rate, May 2026)

Figures are approximate and vary by lender. Always request a written Loan Estimate before purchasing points.

According to Bankrate, on a $400,000 loan, buying two points for $8,000 upfront at 6.5% reduces the monthly payment by $133 and saves $47,858 in total interest over the life of the loan — assuming the mortgage is held for the full 30 years.

For temporary buydowns, costs vary more widely. A 2-1 buydown on a $400,000 loan at 6.5% runs roughly $9,000–$10,000 in total, though sellers or builders typically foot that bill as a purchase incentive.

How to Calculate Your Break-Even Point

The break-even point is how long it takes for monthly savings to recover the upfront cost of the points — and it is the single most important calculation when deciding whether to buy down your mortgage interest rate. Divide the total cost of points by your estimated monthly savings to get the number of months.

On a $400,000 loan at 6.36% (Freddie Mac average, May 2026), one point costs $4,000 and saves approximately $60 per month — a break-even of roughly 67 months (5.6 years). Stay beyond that without refinancing and you come out ahead. Move or refinance before then and you lose money.

With the Federal Reserve having cut rates by 1.75 percentage points since late 2024, further reductions are possible in 2026–2027. If you are considering refinancing your mortgage within 2–3 years, points purchased today will likely not reach break-even — factor that probability into your decision.

Pros and Cons of Buying Down Your Mortgage Interest Rate

Pros

• Lower monthly payments reduce your housing costs immediately and for the life of the loan
• Significant long-term interest savings — tens of thousands of dollars on a 30-year loan at current rates
• Potentially tax deductible on a primary residence purchase (see tax section below)
• Rate is locked in — your reduced rate is permanent for the loan term on a fixed-rate mortgage
• Can help you qualify for a higher loan amount by reducing your debt-to-income ratio

Cons

• Requires cash upfront at closing — money that could otherwise go toward a larger down payment or emergency reserve
• Long break-even period — typically 5–7 years before monthly savings exceed the upfront cost
• Non-refundable — points are not returned if you sell, refinance, or pay off the loan early
• Opportunity cost — the same cash could be invested elsewhere or used to eliminate PMI
• Rate environment risk — in a falling rate environment, locking in points before a refinance eliminates the savings benefit

Are Mortgage Points Tax Deductible?

The tax treatment of points depends on the loan purpose and whether the property is your primary residence.

Primary Home Purchase

According to IRS Publication 936, points paid on a mortgage to purchase your primary residence are generally fully deductible in the year you pay them, provided all of the following conditions are met:

• The loan is secured by your main home
• Paying points is an established business practice in your area
• The points paid are not more than the amount generally charged in that area
• You paid the points from your own funds, not from loan proceeds
• The points are clearly listed on your Closing Disclosure

Refinancing

Points paid on a refinance can’t be deducted all at once. Instead, they must be amortized — spread evenly over the life of the loan. So $3,000 in refinance points on a 30-year mortgage gives you just $100 per year in deductions. One exception: if you used part of a cash-out refinance to substantially improve your primary residence, that portion of points may be fully deductible the year paid.

One more important detail: you have to itemize deductions to claim points at all. The 2026 standard deduction is $32,200 for married couples filing jointly and $16,100 for single filers, per Yahoo Finance/IRS figures. If your total itemized deductions don’t exceed those thresholds, the points deduction is effectively worthless to you. Talk to a tax professional before assuming you’ll see a benefit.

Is It Worth It to Buy Down Your Mortgage Interest Rate?

The honest answer is: it depends on three things — how long you plan to stay, how much cash you have, and what you think rates will do.

Buying points is likely worth it if:

• You plan to stay in the home for at least 7 years without refinancing
• You have substantial cash reserves beyond your down payment, closing costs, and emergency fund
• You believe interest rates will remain elevated or rise further
• The monthly savings help you qualify for the loan or meaningfully improve your budget

Buying points is likely not worth it if:

• You might move or refinance within 5 years — the break-even period makes points a losing proposition
• You are below 20% down and paying PMI — eliminating PMI (typically 0.5%–1.5% of the loan annually) almost always delivers better guaranteed value than buying points
• You are cash-constrained at closing and stretching to cover costs
• You expect rates to fall significantly — further Fed cuts in 2026–2027 could make refinancing attractive before your break-even point

Alternatives to Buying Down Your Interest Rate on a Mortgage

If buying points does not make financial sense for your situation, consider these alternatives before deciding:

Shop Multiple Lenders

Interest rates differ significantly across lenders. The Consumer Financial Protection Bureau stated that borrowers who receive at least three quotes save about $1,500 over the life of their loan compared to others who only get one quote. Shopping lenders is free and doesn’t take as long as you think.

Make a Larger Down Payment

Putting down 20% or more eliminates PMI and often qualifies you for a better base rate — without any break-even period. If you are still saving for a house, prioritizing your down payment over points almost always delivers better long-term value. On a $400,000 loan, eliminating PMI worth 1% annually saves $4,000 per year.

Improve Your Credit Score

Your credit score is one of the largest factors in the rate you are offered. Borrowers with scores of 760 or above typically receive the best available rates. Paying down existing debt and correcting credit report errors before applying can reduce your rate without any upfront cost.

Choose a Different Loan Type

FHA loans, VA loans, and USDA loans sometimes beat conventional rates for eligible borrowers. VA loans in particular require no down payment and no PMI, which can cut total housing costs substantially.

Consider an Adjustable-Rate Mortgage (ARM)

ARMs typically start with rates 0.5–1% lower than 30-year fixed mortgages. If you are confident you will sell or refinance within 5–7 years, an ARM’s initial fixed period may deliver savings without the upfront cost of points.

Wait for Rates to Move

In a falling rate environment — which 2026 increasingly appears to be — waiting a few months to lock your rate may save more than buying points at today’s rate.

When to Buy Down Your Mortgage Rate

Consider buying points when:

• You have substantial cash reserves — still covering 3–6 months of living expenses after paying points and all other closing costs
• You are buying a home you plan to stay in for 7–10+ years without refinancing
• You have compared quotes from at least three lenders and confirmed the point value is competitive — what costs 1 point at one lender may be the base rate at another. This is one of the most important steps in how to manage your money better as a homebuyer.
• Current rates are elevated relative to historical norms, reducing the likelihood of a sharp near-term drop

Avoid buying points when:

• You might need to sell or refinance within 5 years
• The cash would cover a down payment shortfall or eliminate PMI
• You are in an environment where rate cuts are widely expected — refinancing before break-even turns points into a net cost
• You have not confirmed whether the tax deduction actually applies to your situation — not all buyers can itemize, and points provide no tax benefit if your itemized deductions fall below the standard deduction threshold

Frequently Asked Questions

How much does 1 point lower your mortgage rate?

One discount point typically lowers your rate by 0.125%–0.25%, depending on the lender. The standard most commonly quoted is 0.25% per point. On a $400,000 loan, one point costs $4,000 and reduces a 6.5% rate to approximately 6.25%.

How long does it take to break even on mortgage points?

Typically 5–7 years at current 2026 rate levels. On a $400,000 loan at 6.5%, one point ($4,000) saves approximately $60 per month — producing a break-even of roughly 67 months. Stay beyond that without refinancing and you come out ahead.

Is it better to buy points or put more down?

 If you are below 20% down and paying PMI, a larger down payment almost always wins — it eliminates PMI with no break-even period required. If you are already at 20% or above, compare the break-even on points against other uses for the cash.

Are mortgage points tax deductible in 2026?

Points on a primary residence purchase are generally fully deductible in the year paid if you itemize. Refinance points must be amortized over the loan life. The 2026 standard deduction is $32,200 (married filing jointly) and $16,100 (single) — consult a tax professional to confirm itemizing benefits in your situation.

Can the seller pay my mortgage points? 

Yes. Seller-paid points are common in buyer’s markets and new construction. The IRS treats them as if you paid them directly, so they remain deductible if all other IRS requirements are met. Always ask — it is one of the most negotiable items in a home purchase.
