Each spacious apartment includes two bedrooms, a living room, dining room, kitchen, and full bath, with the fourth-floor apartment boasting beautiful city views. Building improvements include a 4-year-old roof, a new boiler, updated electrical system, double-pane windows, an Energy Star furnace and water heater, a programmable thermostat, and a full basement with Bilco doors. Conveniently located near schools, shopping, restaurants, parks, and public transportation, this is an outstanding opportunity for investors seeking steady cash flow and long-term appreciation.
