Overview

§ 01

Move-in ready and loaded with built-in savings — this immaculate 4-bedroom, 2-bath single-story home in Katy's established Mason Lakes community comes with owned solar panels that will be paid off at closing, so you start with lower utility bills from day one. Soaring ceilings and durable wood flooring run throughout the main living areas, while the chef's kitchen features 42-inch maple cabinetry, granite countertops, and a deep undermount sink. The primary suite offers a spa-like ensuite with dual vanities, a separate soaking tub, and a walk-in shower, and two secondary bedrooms share a Jack-and-Jill bath. Enhanced insulation and a high-efficiency HVAC system keep energy costs low year-round, and the garage's finished epoxy floors add a polished final touch. Enjoy a covered front porch, a private rear patio, and easy access to paved community trails and scenic lakes — plus quick commutes via I-10 and the Grand Parkway. Zoned to Katy ISD.

● What this tells you

The §49.452 notice is the only public document that lists a MUD's exact tax rate, outstanding bond debt, and the assessed value used to compute your taxes — direct from the district, not the MLS. If the district is newer or has more bonds outstanding than its neighbors, your effective tax rate will be higher here than just across the street.
