Move-in ready new construction with high-end systems and finishes throughout. The main level features 9' ceilings, a chef's kitchen with Caf appliances, quartz counters, and an electric fireplace set against custom shiplap wall. Oak floors, custom lighting, granite and tile finishes carry through the whole home. Upstairs, a spacious primary suite offers a true retreat with a generous walk-in closet, while the show-stopping third-floor suite opens directly onto a private deck - an ideal spot for morning coffee or evening unwinding. The fully finished lower level extends the living space further, complete with a wet bar, full bath, and direct access to a private backyard, perfect for gatherings or quiet relaxation. With a location that adds an additional layer of value: kayak the Mystic Lakes, walk to Arlington Center, or bike the Minuteman Greenway to Alewife T - moments from local shops, restaurants, and easy highway access. 73 Mystic offers a flexible living space in one of Arlington's most connected locations.
