Rate buydowns are one of the most misunderstood tools in the mortgage world — and in the current Texas market, one of the most useful. Whether you're buying a new construction home with a builder offering incentives or negotiating a resale purchase, understanding how buydowns work can help you get a lower effective rate, reduce your first-year payment, or both.
There are two fundamentally different types of buydowns: permanent and temporary. They work differently, cost differently, and serve different purposes. Let's walk through both.
What Is a Permanent Rate Buydown?
A permanent buydown means you pay "discount points" at closing in exchange for a lower interest rate that lasts for the entire life of your loan. One discount point equals 1% of your loan amount. The rate reduction you get per point varies by lender and market conditions, but a common rule of thumb is that one point reduces your rate by approximately 0.25%.
Example on a $380,000 loan at a base rate of 7.00%:
- 1 point = $3,800 upfront → rate drops to approximately 6.75%
- 2 points = $7,600 upfront → rate drops to approximately 6.50%
On a 30-year loan, dropping from 7.00% to 6.75% saves about $61/month in P&I. Divide the cost ($3,800) by the monthly savings ($61) and you get a break-even point of about 62 months — just over five years. If you stay in the home longer than five years and don't refinance, buying the point made financial sense. If you sell or refinance before then, you gave away money.
The break-even analysis is the central question with permanent buydowns. I run this calculation for every client who asks about points.
What Is a Temporary Rate Buydown?
A temporary buydown doesn't change your note rate — the rate on your loan documents stays the same. Instead, a lump sum of money is deposited into a buydown account at closing, and that account is drawn from each month to subsidize your payment during the buydown period. When the account is exhausted, your payment steps up to the full rate.
The two most common temporary structures are:
The 2-1 Buydown
Your effective rate is reduced by 2% in year one and 1% in year two, then returns to the full note rate in year three and beyond.
Example: Note rate of 7.00% on a $350,000 loan:
| Year | Effective Rate | Monthly P&I |
|---|---|---|
| Year 1 | 5.00% | $1,879 |
| Year 2 | 6.00% | $2,098 |
| Year 3+ | 7.00% | $2,329 |
The total cost to fund this buydown account is approximately $6,720 — the sum of the monthly subsidies across both years. That money has to come from somewhere.
The 1-0 Buydown
Your effective rate is reduced by 1% in year one only, then steps up to the full note rate in year two. Less expensive to fund, less dramatic payment reduction, but still meaningful in year one when buyers are often cash-constrained from moving expenses and home furnishings.
Who Pays for the Buydown?
This is where it gets interesting — and where buyers often leave money on the table by not negotiating properly.
The buyer can pay for the buydown at closing (less common), but the more powerful use of buydowns in the current Texas market is having the seller or builder fund it as a concession. In a negotiation where a seller isn't willing to drop their price, they may be willing to contribute to closing costs — and a funded 2-1 buydown is an excellent use of those seller concessions. You get a lower effective payment for two years while you settle into the home, without paying the cost yourself.
Many Texas builders in 2026 are actively advertising 2-1 buydowns as incentives on new construction. Instead of cutting the list price (which affects their comps), they fund the buydown. This can be a genuinely good deal — but compare it against a straight price reduction to make sure you're getting equivalent or better value.
When Temporary Buydowns Make the Most Sense
A temporary buydown is most useful when:
- You expect to refinance within 2–3 years. If rates drop and you refinance before the buydown period ends, any unused funds in the buydown account come back to you as a credit at closing. You enjoyed lower payments and recovered the unspent cost.
- Your income is growing. If you're early in your career or expecting a raise or promotion, the step-up to the full rate in year three aligns with higher earnings.
- You're cash-constrained in the first year. Moving costs, furnishing a new home, and adjusting to homeownership costs are real. Lower payments in months 1–24 can be valuable even if you pay full rate later.
- The seller or builder is funding it. If it costs you nothing out of pocket, the downside is minimal.
When Permanent Buydowns Make the Most Sense
Permanent points make sense when:
- You plan to stay in the home long-term and the break-even timeline (typically 4–7 years per point) fits your plans.
- You don't expect to refinance soon — meaning the rate savings will compound for many years.
- You have extra cash at closing beyond what's needed for down payment and reserves, and putting it into points is a better use than leaving it in a savings account earning lower returns.
How I Analyze Buydowns for Clients
When you're considering a buydown — whether buyer-paid or seller-funded — I run a full break-even analysis comparing the upfront cost to the monthly savings across multiple time horizons. I also look at whether the same seller concession amount would be better applied to closing costs, a price reduction, or a rate buydown, depending on your specific situation.
There's no universal right answer. The correct choice depends on your rate, loan amount, how long you plan to stay, and whether you're expecting a refinance opportunity in the next few years.
Use my mortgage calculators to model payment scenarios. For a conventional loan with a seller-funded buydown, I can show you exactly what the step-up looks like month by month. Get pre-approved first so I'm working with real numbers when I run the analysis.
Frequently Asked Questions
Can the seller pay for my rate buydown in Texas?
Yes. Seller-paid concessions can be used to fund either a temporary or permanent buydown, subject to program limits. On a conventional loan, the seller can contribute up to 3% of the purchase price in concessions if you're putting less than 10% down (6% if putting 10–25% down). On FHA, the limit is 6%. This is a common negotiating tool in a buyer's market or with motivated sellers and new construction builders.
What happens to the 2-1 buydown funds if I refinance in year one or two?
If you refinance or sell before the buydown period ends, any unused buydown funds are applied as a credit — typically reducing your loan payoff balance. You don't lose the money; it comes back to you at closing. This makes temporary buydowns less risky than many buyers assume, though you should confirm the specific terms with your lender.
Is a 2-1 buydown the same as getting a lower interest rate?
Not quite. A 2-1 buydown reduces your payment for years 1 and 2, but your note rate — the permanent rate on your loan — stays the same. After year two, you pay the full rate. A permanent buydown (paying discount points) actually lowers your note rate for the life of the loan. They serve different purposes: temporary buydowns help with near-term affordability; permanent buydowns lower long-term cost.
