About this home

Under contract-accepting backup offers. This versatile retreat is unlike anything else on the market. A rare Gulfport estate sitting on a truly private double lot, this property blends timeless character with modern upgrades across three separate residences- the main home, a stand-alone cottage, and a garage apartment overlooking a resort-style pool. Whether you’re envisioning multi-generational living, private guest retreats, or income-producing opportunities, the versatility and lifestyle here are unmatched. The main Dutch Colonial home spans over 2,200 sq ft with 3 bedrooms, 2.5 baths, and rich hardwood floors. A spacious updated family room opens directly to the pool deck, while a covered porch overlooks the lush backyard-creating the perfect setting for indoor-outdoor living. The standalone cottage has been completely remodeled from top to bottom and never lived in since. Bright and airy, it features a full kitchen with stone countertops, modern appliances, a stylish bath, lofted bedroom, and luxury vinyl plank flooring. Above the oversized two-car garage, the freshly renovated studio apartment offers abundant natural light, sleek stone counters, and luxury vinyl flooring - plus a bird’s-eye view of the backyard and pool that makes every day feel like a private resort. Step outside and this estate transforms into a tropical sanctuary: a sparkling in-ground pool, outdoor kitchen, travertine patio, and fruit-bearing trees (including mango), all surrounded by privacy fencing. Recent upgrades include one of the roofs (2017), electrical, plumbing, irrigation, gutters, pool resurfacing, tankless water heater, refinished oak and bamboo floors, landscaping, driveway, full interior renovation of the guest apartment, cottage and more - blending peace of mind with lasting appeal. All three residences enjoy private entries both to exterior roadways and interior pool/backyard, making this one of the most flexible and unique estates in Gulfport. Just blocks from the city’s historic waterfront district, vibrant arts and dining scene, and less than 10 minutes to both the Gulf beaches and downtown St. Petersburg- this home offers a one-of-a-kind lifestyle in a prime location without the added cost of being in a flood zone!
