About this home

St. Pete Duplex with Strong Income Potential! This fully renovated (2026) two-story property offers an excellent opportunity for both investors and owner-occupants—live in one unit and rent the other, or maximize cash flow by leasing both. Each unit features 2 bedrooms and 1 bathroom with approximately 750 sq. ft. of living space. The property is now fully occupied , presenting immediate upside unit A is rented for $1650 per month and unit B is rented for $1600 per month giving you $3250 per month X 12 months gives you $39,000 in annual gross income.

Both units include granite countertops, ceiling fans, mini blinds, and their own stackable washer and dryer for added convenience. Exterior highlights include new fencing, including a front privacy fence that enhances curb appeal and creates a more secluded feel. Ideally located just off 9th St. S, the property is minutes from Downtown St. Petersburg, Tropicana Field, and the USF campus. Bartlett Park and the Frank H. Pierce Recreation Center are just steps away.

Value check
Is the price right?
The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
