Overview

Well-maintained, income-producing duplex in a prime South St. Pete location. This split-level property features two updated units one upstairs and one downstairs each thoughtfully improved with major systems and key components already addressed, making this a low-maintenance investment opportunity. The property currently generates $3,073 per month in combined rent. The upstairs tenant has been in place for four years with a flawless payment history. The downstairs tenant has been in place for one year. This duplex has a consistent track record of strong occupancy and reliable rental income. Located next to a park and just minutes from downtown St. Petersburg, USF, hospitals, and major corridors, the property offers excellent accessibility and long-term rental appeal. It is also situated within an Opportunity Zone, providing potential tax advantages for investors. The home experienced minor flood intrusion (less than one inch) during Hurricane Helene the first flood event in the property’s history. All affected areas were professionally repaired, and the damage was minimal. The property did not flood during the subsequent storm. Solid construction, updated interiors, dependable tenants, and over $3,000 in monthly income make this a straightforward, turn-key investment.
