What's special

French drainSplit floorplanHalf an acreExpansive walk-in closetSingle-story homeOversized islandKitchen built for hosting

Tired of homes that look move-in ready but come with a "we'll deal with that later" list? This one's already handled. Set on nearly half an acre in one of Magnolia's most convenient corridors, minutes to The Woodlands and Tomball, this single-story home was upgraded by owners who didn't want surprises: whole-home filtration with reverse osmosis drinking water, a generator, and a French drain mean the big stuff is done. Inside, the split floorplan and dedicated office/flex space give you real separation, while the open living room flows into a kitchen built for hosting: double ovens, oversized island, prep space for days. The primary suite delivers a true retreat with a spa-style bath and expansive walk-in closet. Half an acre. Zero stairs. One less thing to worry about.
