5501 18TH AVENUE S, Gulfport, FL, 33707 | $549,900

MOTIVATED SELLERS will look at all offers. Charming Gulfport Duplex with Income Potential & Park Views!

This masonry duplex in central Gulfport offers incredible flexibility, whether you're looking for an investment opportunity or a multi-generational living arrangement. Located directly across from Tomlinson Park, the property enjoys picturesque views of the pond and fountain, creating a peaceful and inviting setting.

Each unit features two bedrooms, one bath, an open kitchen and living room layout, and a versatile bonus room that can serve as a home office, den, or formal dining area. The east unit has a side entrance that leads to a large open porch, offering a private entry option. The west unit has a rear door that opens to its own private porch facing the backyard. It also boasts a spacious walk-in closet leading to the laundry room, as well as an extra-large, partially finished garage with a bonus bathroom. The enclosed 2-3 car garage and bathroom were finished prior to the sellers' ownership, and no permit records are available for those modifications.

With separate electric and water meters, this property is an ideal investment. A pocket door currently connects the two units, allowing for easy use as a multi-generational home, or it can be closed off to maintain the property as a traditional duplex. Each unit has its own private laundry room with exterior access, providing additional convenience. A brand-new roof was installed in February 2025, ensuring peace of mind for years to come.

The location couldn’t be better, with Tomlinson Park right across the street. Enjoy a morning walk around the pond, catch a little league game, or take advantage of the recreational workout area and playground. Stetson University’s College of Law is just minutes away, and downtown Gulfport, with its charming shops, restaurants, festivals, and nightlife, is a short bike ride or drive. The award-winning Gulf beaches and vibrant downtown St. Petersburg are also just 10 to 15 minutes away, making this an unbeatable location.

Don’t miss this rare opportunity to own a centrally located duplex with income potential and prime Gulfport charm!
