Rare opportunity to acquire a landmark three-unit mixed-use investment property in the heart of Charlestown's historic town center. Built in 1823 and thoughtfully restored, the property combines an established restaurant and event venue, a residential rental unit, and a separate commercial/office unit. The operating restaurant and its equipment are included in the sale, creating an excellent opportunity for an investor or owner-operator. The restaurant and bar accommodate more than 70 guests, plus seasonal outdoor deck seating. The interior features original curved walls, preserved mantels, crown molding, ceiling medallions, exposed post-and-beam construction, wood flooring, and an impressive eastern winding staircase. The main level includes three public restrooms. Upstairs is a private event space with additional dining capacity and its own bar, upgraded in 2020. A full basement and walk-up attic provide substantial storage. Major improvements include a 50-year asphalt roof, 9-zone radiant heating with supplemental wall heaters, upgraded 225-amp electrical service, and refinished floors, all completed in 2011. Additional upgrades include a Bosch Buderus furnace, tankless hot water system installed in 2023, and professionally installed spray-foam insulation in the walls and attic. The detached outbuilding, renovated in 2022, contains two additional units. The upper level offers an oversized modern studio apartment, currently rented for $1,100 per month, with a stackable washer and dryer. The lower level is a separate commercial/office unit that offers additional income potential and flexible business, professional, or storage use.
