Overview

§ 01

Recently updated 4-bedroom, 2-bath home in the heart of Katy's Memorial Parkway. Four true bedrooms give you room to spread out, and one is currently set up as a study, so you can keep it as a home office or flex it back to a guest room, gym or playroom as your needs change. Out back, the pool has been resurfaced and is ready for long Texas summers, weekend cookouts and quiet evenings by the water. Inside, the kitchen features granite countertops and sink with a newer stove and dishwasher, and new dual pane windows and a sliding glass door keep the home bright, quiet and efficient. The big-ticket items are already handled: roof, AC and heater, and water heater have all been replaced, plus solar panels that are fully paid off and convey with the home for real monthly energy savings. Zoned to highly acclaimed Katy ISD, including Taylor High School. Minutes to I-10 and the Grand Parkway with shopping and dining close by. Move-in ready. Schedule your private showing today.

● 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.
