Mortgage Rate Buydown Explained: Temporary vs. Permanent
If you are comparing loan offers in the Oklahoma City metro, you have probably seen the word buydown. This mortgage rate buydown explained guide covers the two main types, temporary and permanent. It shows how each one works, who can pay for it, and how lenders qualify a borrower. It uses numbers so you can see the mechanics. It does not tell you which option to pick, because that depends on your loan, your finances and your timeline.
What is a mortgage rate buydown?
A buydown is money paid upfront to lower the interest rate on a mortgage. The rate is lowered in one of two ways:
- Temporary buydown: the rate is reduced for the first one to three years, then returns to the full rate, called the note rate.
- Permanent buydown (discount points): you pay a fee at closing to lower the note rate for the whole loan.
Both need cash from someone at closing. The difference is how long the savings last and how the loan is set up.
How does a 2-1 buydown work?
A 2-1 buydown lowers the rate by 2 percentage points in year one and by 1 point in year two. From year three on, you pay the note rate.
The lower payments are not free. The money to cover the gap is paid upfront, usually into an escrow account. Each month, the lender draws from that account to cover the difference between the reduced payment and the full payment.
A 3-2-1 buydown adds a third step. The rate is 3 points below the note rate in year one, 2 points below in year two, and 1 point below in year three. The note rate applies from year four.
The loan itself is still a fixed-rate mortgage in most cases. The note rate does not change. Only the payments in the early years are subsidized.
Mortgage rate buydown explained in numbers
These examples are illustrations only, not a quote or an offer. They use a $250,000 loan, a 30-year fixed term and a 6.50% note rate. Payments are principal and interest only. They do not include taxes, insurance or mortgage insurance. Real rates and costs change daily, and your lender's Loan Estimate shows the actual figures.
No buydown: 6.50% for 30 years is about $1,580.17 per month.
2-1 buydown
| Year | Rate | Monthly payment | Monthly difference |
|---|---|---|---|
| 1 | 4.50% | about $1,266.71 | about $313.46 |
| 2 | 5.50% | about $1,419.47 | about $160.70 |
| 3 onward | 6.50% | about $1,580.17 | $0 |
The subsidy adds up to roughly $3,761.52 in year one plus $1,928.40 in year two. That is about $5,690 that must be funded at closing.
3-2-1 buydown
| Year | Rate | Monthly payment | Monthly difference |
|---|---|---|---|
| 1 | 3.50% | about $1,122.61 | about $457.56 |
| 2 | 4.50% | about $1,266.71 | about $313.46 |
| 3 | 5.50% | about $1,419.47 | about $160.70 |
| 4 onward | 6.50% | about $1,580.17 | $0 |
The three-year subsidy comes to about $11,180.64 ($5,490.72 + $3,761.52 + $1,928.40).
Permanent buydown with points
One discount point costs 1% of the loan amount, or $2,500 on a $250,000 loan. How far a point lowers the rate varies by lender, loan type and market conditions. For this illustration, assume one point lowers the rate from 6.50% to 6.25%.
- Payment at 6.25%: about $1,539.30
- Difference from 6.50%: about $40.87 per month
- Cost divided by monthly difference: $2,500 ÷ $40.87 is about 61 months, or just over five years
That last figure is a break-even calculation. It shows how long it takes for the monthly savings to equal the upfront cost. It is arithmetic, not advice. Whether it matters depends on how long a borrower keeps the loan, and no one can know that in advance.
Who pays for a buydown?
The money can come from different sources, and who pays is usually negotiated:
- Sellers: a seller can agree to fund a buydown as part of the purchase contract, often called a seller concession.
- Builders: some builders offer buydowns on new construction, sometimes through a preferred lender.
- Lenders: some lenders offer buydowns as part of a loan package. The cost may be built into the rate or fees.
- Buyers: a buyer can pay for a buydown or points out of pocket.
Loan programs limit how much a seller or other interested party can contribute toward closing costs and buydowns. Those limits differ by loan type (conventional, FHA, VA, USDA) and sometimes by down payment. Ask your lender which limits apply to your loan. A licensed real estate agent can explain how a seller contribution is written into a contract.
What rate do lenders use to qualify you?
This is one of the most common questions. With a temporary buydown on a fixed-rate loan, lenders generally qualify the borrower at the full note rate, not the reduced introductory rate. In the example above, qualification would be based on the 6.50% payment of about $1,580.17, not the year-one payment.
With permanent points, the note rate itself is lower. The lender qualifies the borrower using the lower payment, which can change the debt-to-income ratio.
Guidelines vary by lender and loan program, and they change over time. Your lender can tell you how your loan will be qualified. Nothing in this article is a promise of approval, and that includes borrowers who apply with an ITIN. Approval depends on your credit, income, assets and the lender's guidelines.
How do the two types compare?
| Temporary buydown | Permanent buydown (points) | |
|---|---|---|
| How long the savings last | 1 to 3 years | Life of the loan |
| Note rate | Unchanged | Lowered |
| Typical funding | Often a seller, builder or lender | Often the buyer, sometimes negotiated |
| Qualifying | Generally at the note rate | At the lower note rate |
| Funds held | Escrow account for the subsidy | Paid at closing |
Some details differ by lender. One is what happens to unused buydown funds if the loan is paid off or refinanced early. Ask for the answer in writing.
Where to find official information
- Loan Estimate and Closing Disclosure: these federal forms list points, credits and the interest rate. Check them for any buydown cost or seller credit.
- Consumer Financial Protection Bureau (CFPB): consumerfinance.gov explains mortgage points and closing costs in plain language.

- A tax professional: can explain how points are treated on a tax return. This article does not cover tax treatment.
Local price data for context
Buydown costs scale with the loan amount, so the dollar figures change with the price of the home. As a reference, here are median home prices for May 2026 in several OKC Metro communities:
- Yukon: $234,859
- Mustang: $261,194
- Piedmont: $412,753
- Edmond: $391,766
- Oklahoma City: $270,000
- El Reno: $195,333
These are May 2026 medians. They describe past sales and are not a forecast or a statement about any one home. The $250,000 loan above is a round number for illustration only.
Frequently asked questions
Does a temporary buydown change my interest rate for the whole loan? No. The note rate stays the same. Only the payments in the first one to three years are reduced, and the subsidy is paid in advance.
Can a seller pay for a buydown? Often yes, if the contract and the loan program allow it. Contribution limits vary by loan type, so confirm them with your lender before writing an offer.
Is a 2-1 buydown the same as an adjustable-rate mortgage? No. An adjustable-rate mortgage can change based on an index after its fixed period. A buydown on a fixed-rate loan follows a set schedule, and the note rate does not change.
How much does a discount point lower the rate? It varies by lender, loan type and day. Do not rely on a rule of thumb. Ask the lender for a Loan Estimate with and without points so you can compare the same loan side by side.
