About This Home

This 3-bedroom, 1-bathroom single family at 4105 18TH AVENUE S in Saint Petersburg, FL is listed for $519,900 ($280 per sqft). Built in 1922, the home offers 1,856 sqft of living space on a 0.19 acres lot.

Agent Description

One or more photo(s) has been virtually staged. Live in the beautifully remodeled 3-bedroom, 1-bath main home offering approximately 1,253 total square feet, while collecting rent from the separate 1-bedroom, 1-bath, 603 square foot home to help offset your mortgage payment. This unique property offers the flexibility of owner-occupancy with built-in income, multi-generational living, or long-term investment potential.

The property is zoned NTM-1, a special City of St. Petersburg zoning category designed to allow more housing flexibility than a typical single-family lot. In simple terms, this zoning may allow future redevelopment into additional residential units such as duplexes, triplexes, townhomes, or small multifamily housing configurations (buyer to verify with the City of St. Petersburg).

Situated on an 8,255 SF lot with alley access, the property offers strong future redevelopment potential while still producing immediate income today. The existing setup includes a fully remodeled 3-bedroom main home and a separate 1-bedroom accessory dwelling unit currently generating strong rental income.

Both homes have been extensively updated with remodeled kitchens, fresh interior paint, and newer roofing. Alley access also creates additional flexibility for future parking and site design.

Located within an Opportunity Zone in the rapidly evolving St. Petersburg market, this property offers a rare combination of immediate usability, rental income, and long-term upside for both homeowners and investors alike.
