Rare opportunity to own a beautifully maintained two-family home in Concord's highly desirable South End! Built in 1906, this home is filled with timeless character including original built-ins and architectural details. The first-floor unit welcomes you with a finished sunroom, hard wood floors, first-floor laundry, two bedrooms, a spacious dining room, and a galley kitchen. The vacant second unit offers an exterior deck, mudroom with laundry, kitchen, living room, bedroom, and a versatile third-floor bonus space perfect as a second bedroom, home office, or playroom. Outside, you'll find a detached two-car garage, a newly paved driveway with ample off-street parking, and updated composite decking. Additional improvements include fresh paint and a roof that's just four years new. Each unit is separately metered with its own boiler, electrical panel, and utilities, offering flexibility for owner-occupants or multi-generational living. This South End gem offers a rare combination of flexibility, character, and location. Walk to schools and parks. Showings begin at the Open House on Friday from 4:00 PM to 6:00 PM.
