Rare opportunity to own a legal duplex in North Beacon Hill with flexibility for investors, owner-occupants, or buyers exploring a 1031 exchange. The upper 2-bed, 1-bath unit will be available for owner occupancy at closing, while the ground-floor 2-bed, 1.5-bath unit is tenant occupied at $2,500/month + $60/month W/S/G—live in one unit while generating rental income from the other. The upper unit, with separate access at 1422 S Plum St, features an enclosed entry porch, tall ceilings, beautiful period woodwork and doors, built-in window seating, fresh paint, abundant natural light, and a spacious living/dining room. The eat-in kitchen offers a gas range, generous cabinetry and counter space, plus access to the garden and patio with mature palms, magnolias, and flowering vines. Upstairs bonus space, not included in the listed square footage, offers flexible options for a home office, media room, rec room, hobby space, or additional living area. The ground-floor unit, accessed from 15th Ave S, offers 2 bedrooms, a full bath plus a half bath (1.5 baths) and direct access to shared laundry. Additional property highlights include abundant storage, a newer roof, double-pane windows, gas fireplaces in each unit, plumbing and electrical updates, detached garage, and driveway parking. Conveniently located near bus service and a short distance to Beacon Hill light rail. A rare combination of location, character, income potential, and flexibility.
