Overview

§ 01

This lakeside retreat in gated Grand Harbor on a 1/2-acre canal lot, is moments from the open waters of South Lake Conroe. Built in 2004, but undergoing extensive renovations in 2025, including new flooring, a reconfigured and fully updated kitchen, and all newly updated bathrooms, this 5,161 sq ft home offers 4-5 bedrooms and 4 baths. The kitchen features a large kitchen island with dolomite marble countertops and Bosch appliances, with panoramic views of the saltwater pool and waterfall. The primary suite enjoys sweeping lake views and a marble bath; Jack and Jill baths are finished in quartz. Entertain in the theater room with reclining leather sofas and a wet bar, or the game room with a pool table. An enclosed patio now serves as a gym. Outdoors, the patio and full outdoor kitchen lead to the fire pit area and a new spacious dock for fishing and relaxing, with covered slips for both boat and jet ski. A rare blend of updated living and resort-style lake life.

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.
