139 Alta Mira Court Carefree living at its finest! This stunning home is loaded with high-end upgrades and thoughtful design throughout. Engineered wood floors span most of the main level, complemented by brand-new carpeting and elegant plantation shutters throughout. The welcoming entry foyer features a tray ceiling, while the great room is anchored by a dramatic stone-to-ceiling wood-burning fireplace with a custom mantel—perfect for cozy evenings at home. The deluxe kitchen is a true showstopper, featuring upgraded Frigidaire Professional appliances, staggered 36- and 42-inch cabinetry, granite countertops, and beautiful finishes ideal for everyday living and entertaining. A main floor den/office with french doors offers the perfect space for working from home or a quiet retreat. The spacious laundry room offers a sink, upgraded cabinetry, and granite counters. The primary suite impresses with a coffered ceiling, box bay window, and a spa-like bath with a custom-tiled shower. The walk-out lower level offers 9-foot pour foundation, and is partially finished with a rec room, wet bar rough-in, third bedroom with a walk-in closet, and a third full bath. An additional unfinished area includes rough-ins for a fourth full bath, allowing room to expand. The lower level walks directly out to a 12x21 patio beneath the deck. Outdoor living continues on the 12x21 maintenance-free deck—partially covered—overlooking the subdivision lake, creating a peaceful setting with scenic views. Additional highlights include upgraded 5 1/4-inch base trim with 3 1/4-inch door casings, zoned HVAC with steam humidifier, central vacuum, and a three-car garage with fourth-car tandem space and 8-foot insulated doors. Conveniently located with easy access to Highways 364, 40, and 70, this home perfectly blends luxury, comfort, and location.
