Privately set on a ~3/4-acre cul-de-sac lot in Mostyn Manor Estates, this exceptionally well-kept home offers a wooded setting, generous outdoor living space, and a true sense of seclusion. A wall of windows overlooks the heated pool/spa, covered patio, and expansive backyard framed by mature trees. Inside are 5 bedrooms, including a first-floor secondary bedroom with direct access to a full bath, plus a formal dining room with flexible use options, a formal living room ideal for a home office, and a spacious mudroom off the kitchen with ample storage. The 5th bedroom upstairs can also serve as a game room. Major improvements include the roof, HVAC systems and ductwork, all bathrooms, flooring, interior/exterior paint, lighting, kitchen appliances, and covered patio. Additional highlights include a 3-car garage, extra-wide driveway, and a low 1.58% tax rate with no MUD, all zoned to the new Magnolia Parkway schools. All of this, just minutes from The Woodlands, shopping, and dining.
