Cinco Ranch Real Estate Market Update: Updated September 21, 2026

This is the weekly Cinco Ranch real estate market update, published September 21, 2026, with the most current verifiable figures available on that date. The Cinco Ranch numbers come from Redfin (reporting period August 2026), mortgage rates come directly from Freddie Mac's Primary Mortgage Market Survey (release dated September 17, 2026), and the Houston figures come from the Houston Association of Realtors (HAR, reporting period August 2026). Every metric below is labeled with its value, reporting period, geography, source, and access date, and the numbers are approximate and rounded for readability. They are public-market snapshots, not exact MLS data.

Editor's note: this update reflects the most current public data available as of the September 21, 2026 update.

The short version

The latest labeled data shows a market with more balance than a year ago, alongside a mortgage rate that ticked up. Redfin reports the Cinco Ranch median sale price at $529,649 in the August 2026 reporting period, down 8.9 percent year over year, and the 30-year fixed mortgage rate rose to 6.95 percent in Freddie Mac's September 17, 2026 survey. For buyers that means more choices than a year ago. For sellers it means pricing right from the first week matters more than it did in 2024 or 2025. None of this is a forecast; it is a picture of the market as the most current labeled public data describes it.

Cinco Ranch, the August 2026 picture

For Cinco Ranch itself, the current read is Redfin's housing market data, which tracks the community as its own area (the master-planned community in Katy that spans the 77450 and 77494 ZIP codes). August 2026 is the most recent reporting month Redfin has published. The metric below is for that reporting period.

• Median sale price (all home types): approximately $529,649, down 8.9 percent year over year. Reporting period: August 2026. Geography: Cinco Ranch, Katy area, TX. Source: Redfin. Date accessed: September 21, 2026.

Redfin also publishes median days on market, price per square foot, and homes sold for the community, but those August 2026 values could not be independently verified from the source page at the time of this update, so they are omitted here rather than estimated. The sources section links the page if you want to check them yourself, and address-level numbers for a specific home are always a conversation, not a published number.

Mortgage rates

Freddie Mac's weekly Primary Mortgage Market Survey (PMMS) is the direct, authoritative source for weekly mortgage rates, and the release dated September 17, 2026 is the most current at this update's date. The rates below are U.S. national weekly averages, not a Texas or Katy rate.

• 30-year fixed-rate mortgage: 6.95 percent, up from 6.76 percent the prior week and up from 6.26 percent a year earlier. Reporting period: U.S. national weekly average, Freddie Mac PMMS, as of September 17, 2026. Geography: national average. Source: Freddie Mac Primary Mortgage Market Survey. Date accessed: September 21, 2026.
• 15-year fixed-rate mortgage: 6.26 percent. Reporting period: U.S. national weekly average, Freddie Mac PMMS, as of September 17, 2026. Geography: national average. Source: Freddie Mac Primary Mortgage Market Survey. Date accessed: September 21, 2026.

Greater Houston, for scale

For the regional picture, the Houston Association of Realtors publishes the official monthly market update for Greater Houston. The August 2026 figures are below, labeled as Greater Houston data, not Cinco Ranch data.

• Median single-family sales price: $330,000, down $5,000 from August 2025. Reporting period: August 2026. Geography: Greater Houston. Source: HAR. Date accessed: September 21, 2026.
• Single-family sales: 7,100, down 11.5 percent year over year. Reporting period: August 2026. Geography: Greater Houston. Source: HAR. Date accessed: September 21, 2026.
• Months of inventory: 5.3, with 38,947 active single-family listings. Reporting period: August 2026. Geography: Greater Houston. Source: HAR. Date accessed: September 21, 2026.

Greater Houston is a far larger geography than Cinco Ranch, so treat these as regional context, not a Cinco Ranch price point.

What the data suggests for buyers and sellers

• For buyers: the August 2026 picture shows the Cinco Ranch median sale price down 8.9 percent year over year and Greater Houston carrying 5.3 months of inventory, which points to more choices and more negotiating room than a year ago. Get pre-approved before you look, and talk to a lender about locking a rate, because weekly rate moves change the monthly payment.
• For sellers: with the 30-year fixed rate at 6.95 percent in the September 17, 2026 survey, monthly-payment math is a real factor for buyers, so pricing to current, address-level comps from week one matters. Overpricing now tends to mean a home sits and accumulates market days.
• For everyone: public data lags the market, and this update is one labeled snapshot as of September 21, 2026, not a prediction. Verify anything that matters to a real decision with current information for your specific street or home.
