If you’re waiting for a better mortgage rate before you buy in Houston, bookmark this page. I update it every week with the latest average rates from Freddie Mac’s national survey, plus a plain-English read on what’s moving and what it actually means if you’re sitting on the sidelines. Here’s where things stand right now.
This week’s average mortgage rates
Week of September 17, 2026 · source: Freddie Mac Primary Mortgage Market Survey
| 30-year fixed | 6.95% | up from 6.76% last week |
| 15-year fixed | 6.26% | up from 6.09% last week |
A year ago, the 30-year averaged 6.26% and the 15-year 5.41% — so both averages are running well above where they sat last September, with the 30-year now about seven-tenths of a point above last year’s reading.
These are national average rates for borrowers with strong credit and a solid down payment. Your actual rate depends on your credit, loan type, down payment, and the lender you choose — so treat these as a benchmark, not a quote. I’m a real estate broker and REALTOR®, not a mortgage lender; for a real rate on your situation, I’ll connect you with a trusted Houston loan officer.
What’s moving rates this week
Rates jumped for a fourth straight week — and this was the biggest move of the run: the 30-year fixed climbed to 6.95% from 6.76%, and the 15-year to 6.26% from 6.09%, putting the 30-year nearly seven-tenths of a point above its year-ago reading and within a whisker of 7%. Sam Khater, Freddie Mac’s chief economist, said the 30-year “continues to fluctuate as markets assess economic data” — a reminder that the bond market, not the housing market, is driving this. Mortgage rates take their cues from the bond market — specifically the 10-year Treasury — which reacts to inflation reports, Federal Reserve signals, and the broader economy far more than to anything happening in Houston. When inflation cools or the Fed hints at easing, rates tend to drift down; when the economy runs hot, they climb. Week to week the moves are usually small, which is exactly why trying to time the bottom is so hard — and why the lender you pick can matter more than the day you lock.
If you’re waiting for a lower rate, read this first
I talk to buyers every week who are parked on the sidelines waiting for rates to drop. It’s a completely reasonable instinct — but here’s the honest math you’re weighing. There’s an old line in this business: marry the house, date the rate. The rate you lock today isn’t permanent. If rates fall meaningfully after you buy, you can refinance into the lower one. The house, on the other hand, you only get to buy at today’s price.
That’s the real trade-off behind waiting. While you wait for a lower rate, two things can move against you: home prices can keep rising, and competition can heat up the moment rates drop and every other sidelined buyer jumps back in at once. A lower rate on a higher price — in a bidding war — isn’t always the win it sounds like. To put numbers on it, a $350,000 loan at this week’s 6.95% runs about $2,317 a month in principal and interest. A buyer who locked that same loan a year ago at 6.26% pays about $2,157, so a year of waiting cost roughly $160 a month. Real money, but rarely the thing that should make or break a 30-year decision when prices and inventory are also in play.
None of this means “buy now no matter what.” It means the smart move is to get yourself ready — pre-approved, clear on your budget, and watching the right homes — so that when the right house and a rate you’re comfortable with line up, you can act instead of scrambling. If you want to understand the difference between being pre-qualified and truly pre-approved, I walk through it in my guide to pre-qualification vs. pre-approval.
What today’s rates mean for your Houston payment
Because your rate rides inside your monthly payment alongside principal, taxes, and insurance, even a small change in the rate shifts what you can comfortably afford. At 6.95%, a $300,000 loan is roughly $1,986 a month in principal and interest, a $350,000 loan about $2,317, and a $400,000 loan about $2,648 — before Texas property taxes and homeowner’s insurance are added through escrow. When we sit down to set your budget, I always build the all-in monthly number for the specific homes you’re considering, not just the sticker price, so the payment you see is the payment you’ll actually have. For the full financing picture, see the mortgage information page and the mortgage loan FAQ.
Where these numbers come from
The rates on this page come from Freddie Mac’s Primary Mortgage Market Survey, the most widely cited weekly benchmark in the country. It’s published every Thursday and reflects average rates on conventional, conforming loans for well-qualified borrowers — which is why it’s a reliable gauge of the trend, even if your personal quote lands a little higher or lower. I refresh this post each week after the new survey comes out, so the numbers you’re reading are current.
