Should You Buy Down Your Mortgage Rate? Points vs. 2-1 Buydowns in Houston

With the 30-year fixed hovering around 6.55% this summer, the question I hear most from Houston buyers is some version of: “Can I do anything about the rate itself?” The answer is yes — but “buying down your rate” actually means two very different things, and mixing them up can cost you real money. Let me break both down in plain English so you can tell which one (if either) is worth it for you.

The short version: a permanent buydown (discount points) lowers your rate for the life of the loan and you pay for it. A temporary buydown (like a 2-1) lowers your payment for the first year or two only — and someone else, often the seller or builder, frequently foots the bill.

Permanent: discount points

A discount point is a fee you pay upfront at closing to permanently lower your interest rate. One point costs 1% of your loan amount, and as a rough rule of thumb it buys about a 0.25% lower rate — though the exact trade varies by lender and by the day. The Consumer Financial Protection Bureau requires any point to be “bona fide,” meaning it has to actually reduce your rate by a real amount, not just pad the fees.

Here’s how it plays out on a Houston-priced home. Say you buy around the city’s median — a $340,000 home with roughly $40,000 down, leaving about a $300,000 loan. One point costs $3,000 and might drop your rate from about 6.55% to 6.30%, trimming your payment by roughly $45–$50 a month. That’s real, but do the break-even math: $3,000 divided by ~$48 a month is about five years before the upfront cost pays for itself. If you’ll keep the loan longer than that, points can be a smart buy. If you expect to sell or refinance sooner, that $3,000 is usually better left in your pocket.

Temporary: the 2-1 buydown

A temporary buydown works completely differently. It doesn’t touch your actual note rate at all. Instead, a lump sum is set aside in an escrow account at closing and used to subsidize your payment for the first couple of years. With a 2-1 buydown, your payment is calculated as if your rate were 2% lower in year one and 1% lower in year two — then it settles at the full rate from year three on.

On that same $300,000 loan at 6.55%, a 2-1 would look roughly like this: year one you’d pay as if the rate were 4.55% — about $1,530 a month instead of $1,906, saving close to $375 a month. Year two you’d pay as if it were 5.55%, around $1,715, saving about $190. From year three forward you pay the full $1,906. The whole subsidy in this example runs about $6,800. One thing to keep front of mind: you still have to qualify at the full rate, not the discounted one — the lower early payments are a cushion, not a lower loan.

Who pays for the buydown — and why that matters

Here’s the best part of a temporary buydown: it’s often not you paying for it. In today’s market, builders and motivated sellers frequently fund a 2-1 buydown as a concession to get a deal done, and you’ll see it a lot on new construction across Cypress, Katy, and the communities along the Grand Parkway. When the seller or builder covers the subsidy, you get the lower payments in those early years without paying for them yourself — and if you refinance before the funds are used up, the leftover money typically goes toward your loan balance. That’s exactly the kind of concession I work into an offer for my buyers when the situation calls for it.

So which one makes sense for you?

It comes down to your cash and your timeline. Discount points tend to make sense when you have money to spare at closing, you plan to stay in the home well past the break-even point, and you want a permanently lower payment. A 2-1 buydown tends to make sense when you expect your income to climb, you want breathing room the first year or two, or — best case — a seller or builder is willing to pay for it. Neither is automatically “the deal.” Run the break-even on points, and with a buydown make sure you’re genuinely comfortable with the year-three payment, because that’s the one you actually signed for.

A couple of honest cautions

I’m a broker, not a lender, so treat the numbers above as illustrative — rates move every week, and I keep a running read on them on my Houston mortgage rates page. Your real figures come from a lender’s Loan Estimate, where points and buydown costs are spelled out line by line. And two traps to avoid: don’t buy points just to feel like you beat the rate if you’ll move in three years, and don’t let a low year-one buydown payment tempt you into a home whose full payment you can’t comfortably carry down the road. Used the right way, though, both tools can shave real dollars off the cost of buying — and the right one depends entirely on your plan.
