Rising Interest Rates in Houston: What It Really Means for Buyers and Sellers

Mortgage rates just hit a one-year high in the Houston market — the 30-year fixed is sitting at 7.05% this week, up for four straight weeks and nearly 70 basis points higher than a year ago. If you’re weighing whether to buy or sell in the coming months, that number changes the math. Here’s what’s actually happening, and what to do about it.

Where Things Stand Right Now

As of September 18, 2026, the 30-year fixed mortgage rate is at 7.05%, and the 15-year fixed is at 6.43%. Just a few months ago, some Houston buyers were locking in closer to 6.33%.

Locally, the picture is shifting too:

  • Median home price: $332,000, down about 1.6% year-over-year
  • Active single-family listings: 36,572, up 6.5% year-over-year
  • Average days on market: 60, up from 55
  • Months of inventory: 4.9, above the national average of 4.1

More homes on the market, prices leveling off, and listings sitting a little longer — combined with higher rates, that adds up to a market that has shifted meaningfully toward buyers compared to the last few years, even as affordability stays the central challenge.

Why Rates Are Rising

Two forces are colliding. The Federal Reserve raised its target rate on September 16 — its first hike in over three years — to get ahead of inflation. At the same time, geopolitical tensions, including the conflict involving Iran, have pushed oil prices higher, feeding directly into inflation. Lenders are responding by holding rates firm or pushing them higher rather than risk cutting into that environment.

Most economists expect these higher rates to stick around through the end of the year. That’s not a reason to panic — it’s a reason to stop waiting for a number that may not come and start planning around the one we actually have.

What This Means for Buyers

Here’s the math on a Houston median-priced home. On a $332,000 purchase with 20% down, financing $265,600:

  • At 6.33% (roughly where rates sat earlier this year): about $1,650/month in principal and interest
  • At 7.05% (today): about $1,775/month

That’s roughly $125 more a month, or $1,500 a year, for the same house.

For first-time buyers using an FHA loan with 3.5% down, the math looks a little different. On that same $332,000 home, the loan amount is about $320,380:

  • At 6.33%: roughly $1,990/month in principal and interest
  • At 7.05%: roughly $2,140/month

That’s about $150 more a month. Keep in mind FHA loans also carry mortgage insurance premiums on top of principal and interest, so factor that into your total payment once you’re pre-approved.

But buyers have leverage they didn’t have two years ago. With 4.9 months of inventory and homes averaging 60 days on market, sellers are more open to covering closing costs or buying down your rate than they were in 2022 or 2023. A temporary or permanent rate buydown built into your offer is often more cost-effective than simply paying more for the house. And trying to time a rate bottom is risky: if rates drop later, you refinance; if home prices climb again once rates fall — which is historically what happens — waiting cost you the discount on the house to save a little on the rate.

The rule of thumb: marry the house, date the rate.

What This Means for Sellers

Today’s buyer pool is smaller and more rate-sensitive than it was two years ago, and they’re doing this exact math before they write an offer. Three things matter most right now:

Price it to today’s data. With the median price down about 1.6% year-over-year and days on market climbing to 60, an overpriced listing doesn’t just sit — it signals to buyers that something’s wrong. Price against current comps, not last year’s.

Lead with concessions, not price cuts. A rate buydown or closing-cost credit can make your home meaningfully more affordable to a buyer without lowering your list price, and it frequently costs less than a straight price reduction would.

Don’t wait for rates to drop. When rates do fall, the buyers who’ve been waiting on the sidelines come back all at once — and you’ll be competing with more sellers, too. Less competition right now can work in your favor if the home is priced and presented well. With active inventory up 6.5% year-over-year, strong photos, decluttering, and smart pricing are what separate a home that sells in three weeks from one that sits for three months.

The Bottom Line

If you’re buying: get pre-approved now, factor a rate buydown into your offer strategy, and use today’s inventory to negotiate rather than waiting on a rate that may not come.

If you’re selling: price to today’s market, lead with concessions before touching your list price, and invest in presentation, since you’re competing against more listings than a year ago.

Rates will move, and Houston’s market always does. The buyers and sellers who come out ahead in a market like this aren’t the ones waiting for perfect conditions — they’re the ones who know the numbers and move with a plan.
