LIVE IN PARADISE in the heart of OLD SOUTHEAST! Just minutes from vibrant Downtown St. Petersburg, this fully renovated home features an ADU that can either be used for extra income or an in-law suite. Nestled just four blocks from Lassing Park, and close to USF St. Pete, Bayfront & Johns Hopkins Hospitals, this property features two detached units: a 2-bed/1-bath front home and a 1-bed/1-bath ADU with a private fenced yard and alley access. Each unit is separately metered for electric, with a tenant covering their own utilities. Whether you’re an investor seeking strong rental income (with a history of consistent occupancy), or a buyer looking to live in one unit while renting the other, this property delivers. The neighborhood is rapidly growing with redevelopment and rising property values, making this an ideal opportunity for both immediate cash flow and long-term appreciation. Don’t miss your chance to Live and Own or simply invest in one of St. Pete’s most desirable and walkable neighborhoods! StellarMLS TB8388215
