Property Description
Breathtaking water views and immediate ocean access set the stage for an exceptional waterfront lifestyle at this stunning and impeccably kept modern 2-story home in Sombrero Beach, an exclusive neighborhood of high-end homes just steps to the beach and minutes to Marathon Jet Center. Offering 4 bedrooms, 5 bathrooms, and approximately 3,500 sq. ft. of beautifully appointed living space, this waterfront retreat places the Atlantic Ocean just moments from your dock. Soaring ceilings and an expansive open floor plan create a bright, inviting atmosphere with stunning water views from the main living areas. The chef's kitchen features marble countertops, premium stainless steel appliances, a wine cooler, and a spacious island with seating for four, flowing seamlessly into the dining and living areas. A separate sitting area offers additional space to unwind. Upstairs, two generously sized primary suites each feature private balconies with glass railings showcasing panoramic ocean views, along with luxurious en suite baths featuring soaking tubs and separate rain showers. A wet bar with an ice maker, mini refrigerator, and wine cooler sits between the suites. Two additional guest bedrooms are located on the main level with a bath for each. Outside, an expansive lanai surrounds the heated saltwater pool and spa, complemented by a poolside tiki hut with a fully equipped outdoor kitchen, grill, refrigerator, microwave, and TV. A convenient cabana bath provides easy access from the pool area. Boating enthusiasts will appreciate the 50' dock, 14,000 lb. boat lift, fish-cleaning station, and immediate Atlantic Ocean access. Solid CBS construction with concrete roof and impact doors and windows. Zoned for weekly vacation rentals, this property offers solid rental history and presents an excellent investment opportunity.
