How to Get a 3.99% Mortgage Rate Right Now (Legally): Interest Rate Buydowns Explained

Patriot Nation, we are in 2026, and we know where interest rates are. Freddie Mac's 30-year average hit 7.03% for the week of September 24, 2026, its highest level in a year, so most buyers are looking at rates right around 7% depending on credit scores and loan program. But what if I could get you a rate that starts about two points below that, saving you thousands of dollars without costing you a penny out of pocket? That is the magic of interest rate buydowns. Let me show you exactly how it works.

1. The Hook: What If You Could Get a Two-Point Discount?

What if you could get a rate about two points below market the first year, one point below the second year, then your market rate for the rest of the loan, saving you thousands without spending a penny out of pocket? That is exactly what an interest rate buydown can do for you. Through skillful negotiation with the seller, we can use seller concessions to pay for your rate reduction for the first couple of years. No extra cash from you. Just lower payments when you need them most.

On an average $300,000 first home purchase with a note rate around 6.99%, you are going to save about $385 per month for the first 12 months and about $197 per month for the second year. That is putting thousands of dollars back into your pocket that you can use for anything you want.

2. What Is an Interest Rate Buydown?

An interest rate buydown is simply this: the lender lowers your interest rate for a set number of years in exchange for upfront money. Usually that covers the first, second, or third years. The key difference from discount points is that buydowns are paid by the seller, not the buyer. That is a crucial distinction.

A discount point is something you, the buyer, pay to permanently buy down the rate for the full 30-year term. Each point is 1% of the loan amount. The interest rate buydown is something we want the seller to pay for through seller concessions. We do not want you to pay anything extra.

3. Types of Buydowns

Let us assume a note rate of 6.99%, right around the 7.03% Freddie Mac 30-year average for the week of September 24, 2026, and realistic for a buyer with a 680 FICO score using an FHA loan. Here are the three main types of temporary buydowns:

4. Worked Example: $300,000 FHA Purchase

Let us put real numbers on a 2-1 buydown. We will use a $300,000 purchase with an FHA loan, 660-680 credit score, and a note rate of 6.99%.

In the first year at 4.99%, your principal and interest payment is about $1,609. At the note rate of 6.99%, it would be $1,994. That is a $385 difference per month, or $4,620 in year one alone. In year two at 5.99%, your payment is $1,797, saving you $197 per month, or $2,364 over the second year. Over the full 24 months, you save about $7,000.

5. How to Get the Seller to Pay

How do you actually get the seller to pay for your buydown? Sellers are not just going to roll over and write a check. But in a balanced market, which is where we are right now in Texas and across much of the country, you can negotiate pretty fairly.

On a $300,000 purchase, I am averaging about $10,000 in seller concessions for my clients. The cost to set up a 2-1 buydown on that loan is approximately $7,000. So we take $7,000 out of the $10,000 in seller concessions and allocate it to the buydown fund. You still have $3,000 left over from the concessions to lower your closing costs. Your cash-to-close goes down, and your rate goes down. Win-win.

6. Where the Free Buydowns Live Now: Builders

In 2026 the cheapest buydowns are coming from builders, not from lender promotions. With rates over 7%, San Antonio builders are advertising 2-1 buydowns, permanent rate buydowns, and closing-cost credits on top, and each offer is a different deal. Some builders fund the buydown themselves so you get the low first-year payment without paying points, and the tradeoff is almost always the preferred lender and sometimes the title company.

A builder-funded 2-1 buydown works exactly like the example above: the note rate stays near market, the builder pays the buydown fund, and your payment steps up after year two. The difference is who writes the check, and the catch is whether the builder's lender nets better than an outside quote. Sometimes the builder's lender really is the best deal, and Patrick will say so when it is.

7. Buydown vs. Using All Seller Concessions for Closing Costs

This is the balancing act every buyer faces. You have a fixed pool of seller concessions, and you get to choose how to use them. You have two main strategies:

Both strategies are valid. It depends on your financial priorities. If lowering your monthly mortgage payment is more important, use money towards the buydown. If you are more concerned about writing the smallest check possible, use all the concessions to slash your closing costs. I work through this decision with every buyer to find the right balance.
