Overview

§ 01

Coastal living with water views and plenty of space to enjoy! This beautifully updated 3-bedroom, 2-bath beach home features an open layout with soaring cathedral ceilings and a wall of windows filling the living area with natural light. The spacious kitchen offers a large breakfast island with storage and flows into the dining and living areas with beach views. The primary suite is a comfortable retreat, while two guest bedrooms offer plenty of room for family and friends. Step outside to the expansive upper deck to catch the Gulf breeze, or head downstairs to the large covered entertaining area-perfect for gatherings after a day at the beach. An outdoor shower and half bath in the garage make beach days even easier, and the fully fenced yard adds privacy and room to relax. Sold fully furnished and move-in ready, with the beach and neighborhood amenities just a short walk away. An inviting choice for a full-time home, weekend getaway, or vacation rental.

MUD Disclosure (§49.452)

§ 03 · Data moat
● §49.452 Notice
Not in archive
This MUD is not yet in our §49.452 archive. We'll add it on request.

Texas Water Code §49.452 requires districts to publish annual notices with tax rate, bonded indebtedness, and assessed value. Most Harris-area MUDs publish these; a handful managed by Inframark do not.

Request this notice
● 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.
