A rare and irreplaceable opportunity in the heart of Blue Mountain Beach, this legacy Gulf-front property has been held by a single family since 1970 and has never before been offered for sale in its 56-year history! With 74.54 ft of direct Gulf frontage, an elevated at 28.5 ft, grandfathered 5 ft side setbacks, and property rights extending to the mean high water line, it represents the kind of coastal asset investors and builders wait years to secure. Short-term rental friendly and uniquely positioned away from public beach access points, the lot offers enhanced privacy and guest appeal while still enjoying convenient access to all that 30A offers. Just down from where Blue Mountain Road meets the Gulf and Big Redfish Lake, the property sits near spectacular coastal dune lake outflows and a natural buffer between Grayton Beach and Blue Mountain Beach, helping preserve the serene, low-density character of this shoreline and naturally discouraging overcrowding. Tucked on a quiet, low-traffic street, the property is an ideal foundation for a future luxury residence or high-performing vacation rental. The existing Old Florida cinderblock cottage, with a 2022 roof, offers 4 bedrooms, 2 baths, approx. 1,760 sq ft, with a fireplace, and is largely original-an excellent canvas for redevelopment, room for a pool, expanded footprint, and extensive outdoor living, or a complete reimagining into a new Gulf-front estate that maximizes the lot's width, elevation and investment potential!
