Description

Tropical Waterfront Escape | 11243 3rd Avenue Gulf, Marathon, FL 33050 Welcome to your ultimate Keys getaway — a spacious and stylish waterfront retreat in the heart of Marathon that's fully equipped for vacation rental success or relaxed tropical living. With 5 bedrooms, 4 full baths, and a flexible layout that comfortably hosts up to 12 guests, this property offers a rare blend of island charm, income potential, and exceptional amenities. Step inside to discover an inviting open-concept interior featuring a chef's kitchen with a gas range, stainless appliances, and generous prep space. The primary suite is a private sanctuary complete with a king bed, sofa bed, and spa-inspired ensuite bath. Additional guest rooms are thoughtfully appointed with a mix of king, queen, and twin accommodations — ideal for large families or groups. Outdoors, unwind by the 330 sq ft private pool, complete with TWO new tiki huts — one poolside and another near the fish cleaning station for added shade and entertaining. The brand-new putting green, oversized yard, and game zone (including ping pong, Pac-Man, foosball, basketball, and giant yard games) make this home the perfect playground for all ages. Boaters and anglers will love the 115-ft private dock with water and power — plenty of room for multiple boats. A bait freezer, ice maker, and shaded cleaning station add convenience for your next big catch. There's even room to park an RV, plus additional space for cars and trailers. This property is being sold fully furnished and vacation rental ready, complete with future bookings and repeat guests, making it an easy turn-key investment. An affordable assumable flood policy sweetens the deal. Don't miss this rare opportunity to own a piece of paradise that truly has it all — space, income, lifestyle, and location. Schedule your private showing today and get ready to live the dream in the Florida Keys! Interior Photos are coming soon!
