What is a rate buydown?

A rate buydown is when you (or the seller) pay upfront to lower your interest rate. It can be permanent (for the life of the loan, like discount points) or temporary (for the first few years). A lower rate means a lower mortgage payment. The cost appears on your Loan Estimate and Closing Disclosure (TRID) as part of closing costs.

What is a permanent buydown?

A permanent buydown (discount points) lowers your rate for the entire loan term. You pay points at closing (typically 1% of the loan amount per point) in exchange for a lower rate and mortgage payment. See What Are Mortgage Points and Mortgage Points vs Rate Trade Off.

What is a temporary buydown?

A temporary buydown (e.g., 2-1 buydown) lowers your rate for the first year or two, then it steps up to the note rate. Often used when the buyer expects income to rise. The upfront cost is paid at closing. See Temporary Rate Buydown Explained.

Who pays for a buydown?

The buyer, seller, or builder can pay. Seller-paid buydowns are sometimes used as a concession to help the buyer qualify or afford the payment. The cost is part of closing costs and appears on the Loan Estimate. See Seller Paid Closing Costs Explained.

Does a buydown affect my Loan Estimate or APR?

Yes. The buydown cost appears on your Loan Estimate (TRID) as part of closing costs. A permanent buydown typically lowers your APR. A temporary buydown may have a smaller effect on APR since the lower rate is only for a few years. See What Is APR.

Can a buydown help me qualify?

A temporary buydown can help if underwriting uses the reduced payment to calculate DTI. The first-year payment may be lower, which could improve your debt-to-income ratio. Program rules vary. See What Is DTI and Mortgage Points vs Rate Trade Off.

Introduction

A rate buydown lowers your interest rate by paying upfront. A permanent buydown (discount points) lowers the rate for the life of the loan and reduces your mortgage payment each month. A temporary buydown lowers it for the first year or two, then steps up to the note rate.

The buydown cost is part of your closing costs and appears on your Loan Estimate and Closing Disclosure (TRID). First-time homebuyers may see buydowns offered by sellers or builders. See Temporary Rate Buydown Explained, What Are Mortgage Points, and Mortgage Points vs Rate Trade Off.

What This Means

You (or the seller) pay money at closing to reduce your interest rate and mortgage payment. With a permanent buydown, the lower rate lasts for the entire loan. With a temporary buydown (e.g., 2-1 buydown), the rate is reduced for year 1 and year 2, then steps up to the full note rate. Your loan amount stays the same—only the rate and payment change.

The buydown cost is added to your closing costs. Your Loan Estimate (TRID) shows the rate, mortgage payment, and costs. See What Is APR, What Is Interest Rate, and What Is Amortization.

How It Works: Buydown Types

Type	Duration	Effect
Permanent (discount points)	Life of loan	Lower rate and mortgage payment forever
Temporary (e.g., 2-1)	Year 1–2 (or similar)	Lower payment initially; steps up to note rate

Both add to closing costs. Your Loan Estimate (TRID) shows the rate and payment for each option.

How It Works

A permanent buydown is the same as discount points. You pay 1% of the loan amount per point (typically) in exchange for a lower interest rate. The rate reduction varies by lender. Your mortgage payment is lower for the life of the loan. The cost appears in the origination or discount section of your Loan Estimate (TRID).

A temporary buydown (e.g., 2-1 buydown) lowers the rate by 2% in year 1, 1% in year 2, then the full note rate. The lender or a third party (seller, builder) funds an escrow account at closing. That account subsidizes your lower payments. Underwriting may use the reduced payment for DTI if the program allows. See What Is DTI, What Is LTV, and What Is Mortgage Principal.

Realistic Example Scenario

Morgan gets a $300,000 loan. Without a buydown: 7% rate, $1,996 mortgage payment (P&I). Morgan chooses a 2-1 buydown. The seller pays $6,000 at closing. Year 1: 5% rate, $1,610 payment. Year 2: 6% rate, $1,799 payment. Year 3+: 7% rate, $1,996 payment.

Morgan's closing costs include the buydown (seller-paid in this example). The Loan Estimate shows the payment schedule. The example is illustrative. See Seller Paid Closing Costs Explained and Mortgage Closing Cost Breakdown.

Key Takeaway

A rate buydown lowers your interest rate and mortgage payment by paying upfront. Permanent = lower rate for life (like discount points). Temporary = lower rate for 1–2 years, then steps up. The cost is part of closing costs and appears on your Loan Estimate (TRID). Buyer, seller, or builder can pay.

Why This Matters for Homebuyers

First-time buyers may see buydowns offered by sellers or builders as an incentive. A temporary buydown can lower your mortgage payment in the early years when income may be tighter. It can also help with underwriting if the lender uses the reduced payment for DTI.

A permanent buydown (discount points) reduces your payment for the life of the loan but increases closing costs. Calculate break-even to see if it pays off. Your Loan Estimate (TRID) shows the rate, payment, and costs for each option. See Mortgage Points vs Rate Trade Off and Loan Estimate Explained.

Pros and Cons of Rate Buydowns

Permanent Buydown

Lower rate and payment for life
May lower APR
Higher closing costs
Break-even: compare cost to monthly savings

Temporary Buydown

Lower payment in early years
May help DTI for qualification
Seller/builder may pay
Payment steps up after 1–2 years

Common Mistakes

Confusing permanent and temporary: Permanent (discount points) lowers your rate for the life of the loan. Temporary lowers it for 1–2 years, then steps up. Know which you are getting and plan for the step-up.
Not checking the Loan Estimate: Your Loan Estimate (TRID) shows the buydown cost, rate, and payment schedule. Verify the numbers. Temporary buydowns have a payment schedule—year 1, year 2, year 3+.
Assuming seller-paid buydown is free: The seller may pay, but the cost is often reflected in the purchase price or negotiated as a concession. Understand the full deal. See Seller Paid Closing Costs Explained.
Ignoring the step-up on temporary buydowns: Your payment will increase after year 1 or 2. Budget for the higher payment. If your income will not rise, a temporary buydown may not be the best fit.
Paying for a permanent buydown without calculating break-even: Divide the cost by the monthly savings. If you refinance or sell before break-even, you lose money. See Mortgage Points vs Rate Trade Off.
Assuming all lenders offer buydowns: Buydown availability varies by lender and program. Ask if a temporary or permanent buydown is available and what it costs. See What Are Mortgage Points.
