11919 Mackey Street RARE OPPORTUNITY!........Welcome home to this spacious 3-bedroom, 3.5-bath Half-Duplex featuring a fully finished WALK-OUT basement in the highly desirable Westmont/Sumarlee Estates neighborhood, located within the Blue Valley School District. This home offers three fully finished levels of comfort, style, and convenience. Step inside to a light-filled main level with soaring ceilings and a spacious living room, perfect for everyday living or entertaining. Separate formal and casual dining areas give you flexibility for holidays and weeknight dinners alike. The kitchen shines with granite countertops, painted cabinetry, tile flooring, and updated appliances, while a main-floor half bath and laundry room keep daily life simple. Upstairs, carpeted flooring leads to a comfortable primary suite with separate closets and an en-suite bath featuring a jet tub, walk-in shower, double vanity, and tile flooring. Two additional bedrooms share a full guest bath. Downstairs, the true showstopper is a finished walk-out basement with a sliding glass door that opens directly onto the rear concrete patio, blurring the line between indoor and outdoor living. Use it as a rec room, home theater, home office, gym, or guest space, with a full bathroom on this level for total convenience. The walk-out design provides natural daylight and easy outdoor access, unlike a typical dark basement. Outside, unwind on the main-level wood deck or basement-level patio overlooking a green backyard framed by white vinyl fencing, with morning sun and evening shade. A new roof installed in 2023 adds peace of mind, and nearby trails and a park. Additional features include an included whole-home water softener and Vivint smart security system, a two-car garage, a spacious driveway, and quick access to highways, shopping, and restaurants. HOA dues are currently $86 per month and cover lawn care, snow removal, trash pickup, leaf removal, and bush trimming.
