Do homes in 77493 have MUD taxes?

Many newer subdivisions outside Katy's older city grid are served by municipal utility districts, which finance water, sewer and drainage infrastructure. Municipal utility district taxes appear on the property tax bill and vary by district, so check the specific district and its current rate for any address before making an offer.

Is flooding a concern in 77493?

Katy sits on flat former rice-farming land near the headwaters of Buffalo Bayou, so drainage and flood-zone status can differ from street to street. Check any address on FEMA flood maps, review Harris County Flood Control District, Fort Bend County drainage or Waller County floodplain information for the relevant county, and ask for the seller's disclosure and any elevation certificate.
