Market context

Houston is cooling with rates above 7%. The Houston Association of Realtors reported 7,030 single-family closings in September 2026, down 5.7% year over year, pending sales down 11.6%, active listings up 6.3% to 40,192, and 5.5 months of inventory, with the median price unchanged at $325,000; the condo and townhome segment was weaker, with closings down 21% and 9.3 months of inventory (source).

Nationally, the backdrop is weak demand and slowly building supply. Freddie Mac's survey put the average 30-year fixed rate at 7.32% on October 22, 2026, down from 7.40% the week before but well above 6.19% a year earlier (source). Redfin counted 281,749 pending sales in the four weeks ending October 18, down 14.4% from a year ago and the lowest level in its records, while active listings nationwide were up 2.1% (source).

What it means for buyers in Katy

Supply in Katy is close to where it was a year ago (2,824 active listings versus 2,774), so the big change for buyers is on the cost side, not the choice side. Use the slower fall pace to negotiate on price and credits, and watch the master planned communities, where Cinco Ranch and Cane Island listings fell month over month while Grand Lakes rose. Cross Creek Ranch offers the most options to compare.

What it means for sellers in Katy

Sellers in Katy are competing against roughly the same number of listings as last September, but with fewer active buyers because of mortgage rates. Pricing at or slightly below the most recent comparable sale, and offering a rate buydown credit instead of a price cut, are the tactics that are working in balanced markets like this one. Expect the most competition in Cross Creek Ranch.

Methodology

TurboHome analysis of MLS data via Snowflake. Active listing counts are month-end snapshots of listings with an active status inside Katy city limits, from Apr 2025 through September 2026, the latest complete month. Houston area counts begin in April 2025 because MLS coverage for the region expanded in early 2025 and earlier months are not comparable. Deleted or withdrawn records are excluded. Property types shown are single family residences, condominiums, and townhouses; the all listings total also includes other residential types such as duplexes and manufactured homes, so the three columns do not sum to the total. Neighborhood counts cover neighborhoods with at least 5 active listings in September 2026 and are limited to the 8 largest by current count. Neighborhood figures are compared month over month only, because the share of listings assigned to a named neighborhood has grown over the past year and a year over year neighborhood comparison would overstate the change. All figures are aggregates; no individual listing data is published. Counts come from the MLS feeds TurboHome tracks and can differ from county or metro figures published by local Realtor associations, which use different boundaries and definitions.
