Beautiful end-unit townhouse condo. Need 3 bedrooms. As the 2nd largest townhouse unit in Concord Crossing you get the benefit of 3 bedrooms due to the large second floor bonus room that makes this home a three bedroom in everything but name.Hardwood floors, a living room, kitchen, dining area, family room, half bath, and in-unit laundry on the first floor. The second floor has a full bath, 3 large rooms with large closets in every room including 2 walk in closets and lots of storage in the clean and insulated walk up attic/loft space on the third floor. Looking for single floor living potential? With a simple conversion of the ground-floor half bath to a full bath, the main level could function beautifully for single floor living. Additional highlights include a large garage, insulated walk-up attic, abundant storage, and newer HVAC and gas furnace. Conveniently located near the North Billerica commuter rail, this home offers an easy ride into Boston, along with nearby shopping, major highways, and Billerica Memorial High School. A low-maintenance, owner-occupied community and a move-in-ready lifestyle.
