EXCELLENT INVESTMENT OPPORTUNITY in the highly sought-after OLD SOUTHEAST neighborhood of St. Petersburg! Just four minutes from vibrant Downtown St. Pete, this fully renovated income-producing duplex is perfectly positioned near the University of South Florida St. Petersburg campus, several major hospitals, and the beautiful, dog-friendly Lassing Park. Both units are currently rented with a strong track record of continuous occupancy due to the area's high demand. The property features two separate buildings: the front building offers 2 bedrooms and 1 bathroom, while the rear building is a 1-bedroom, 1-bath unit with its own fenced entrance and parking accessed from the alley. Each unit is separately metered for electricity, with tenants responsible for their own utilities. Located in one of the fastest-growing areas of St. Petersburg, this property not only offers immediate income but also significant long-term capital investment potential, with the surrounding neighborhood experiencing rapid development and appreciation. Whether you're looking for a turnkey rental or a future redevelopment opportunity, this is a rare find. Please do not disturb tenants; showings are by appointment only.
