Buying a Resale Home in Katy, TX: Your Questions Answered

Looking at existing homes in Katy, Texas? "Katy" covers far more ground than the city itself, and that affects your taxes, utilities, and schools. Here are direct answers to the questions buyers ask most.

Is a "Katy" address actually in the City of Katy?

Often it isn't. Many homes with a Katy mailing address are in unincorporated Harris, Fort Bend, or Waller County, and the city itself spans all three counties. The county and city status of an address decide your tax rates, your appraisal district, and who provides water and trash service. We confirm this before you make an offer.

Are property taxes high in Katy?

It depends on the exact address. Homes outside city limits often pay a MUD (Municipal Utility District) tax instead of a city tax, and many neighborhoods also have HOA dues. Two homes at the same price can have very different monthly payments, so we compare full tax rates side by side. Once you move in, file your homestead exemption with your county's appraisal district: Harris, Fort Bend, or Waller.

Does Katy flood?

Some parts of the Katy area have flooded, including neighborhoods near the Addicks and Barker reservoirs during Hurricane Harvey in 2017. Many others have not. Flood risk is specific to each address. We check the FEMA flood map, the seller's disclosure of past flooding and insurance claims, and whether the home has flood insurance today. NFIP flood policies usually take 30 days to take effect, so get a quote early.

What should I watch for in an older Katy home?

Older homes are often well-located and well-kept, but plan to check the roof age, HVAC system, water heater, and foundation. Southeast Texas clay soils expand and shrink with moisture. Some homes built roughly between the late 1970s and mid-1990s may have polybutylene plumbing, which inspectors flag. A general inspection, plus a foundation or plumbing specialist when needed, tells you what you're buying.

How do I compete in a busy market without overpaying?

A strong offer isn't always the highest price. Clean terms, a solid pre-approval, a reasonable option period, and a flexible closing date can make an offer stand out. Before you offer, we review recently sold, comparable homes so your price is based on real sales, not list prices.

What if the inspection finds problems?

Use your option period. During this negotiated window, you can ask for repairs or a credit, or end the contract for any reason and get your earnest money back. The option fee itself is not refunded.

Which school district is a Katy home in?

Most Katy-area addresses are zoned to Katy ISD, but some fall into neighboring districts, and zoning can change. Confirm the assigned schools for a specific address directly with the district.

Do I need a buyer's agent, and who pays them?

You're not required to have one, but your agent negotiates and protects your interests. Texas buyers sign a written buyer agreement before touring homes. Compensation is spelled out in that agreement and is always negotiable. Sometimes the seller agrees to pay part or all of it.
