Welcome to Mariner's Retreat, an extraordinary waterfront estate and development opportunity in the heart of historic Terra Ceia, Florida. Nestled along more than 475 feet of pristine shoreline on Tillette Bayou and Terra Ceia Bay, this rare Old Florida sanctuary spans approximately 9.64 acres across three parcels, offering a seamless blend of private coastal living and investment-grade potential. Anchoring the estate at 1470 Bayshore Drive is a meticulously updated, three-story residence encompassing over 3,600 square feet under air with a brand new roof. Renovated in 2018, the home features impact-rated windows and doors, an updated kitchen and baths, new flooring and lighting, and a 2023 HVAC system. Mangrove trimming is underway to enhance sweeping water views-all the way to the iconic Sunshine Skyway Bridge. From the private dock, enjoy direct boating access to Terra Ceia Bay and the Gulf of Mexico within minutes. Whether it's world-class fishing, dolphin sightings, or tranquil sunset cruises, life here flows with the rhythms of the water. Beyond the residence, the offering includes two development parcels across the street-1450 and 1460 Bayshore Drive-totaling over 8 acres of upland terrain with mature Florida landscape. Supported by a completed environmental study, these parcels offer the potential for additional homesites to be built under Planned Development Residential (PD-R) zoning and a RES-1 land use designation. Specifics available upon request. The entire estate falls within Flood Zone AE, with base elevations of 9 to 10 feet, and offers flexible acquisition options, including the ability to purchase the entire estate or individual parcels. Owner financing may be considered for qualified buyers along with additional information and environmental reports. Mariner's Retreat presents a rare opportunity to own a legacy estate that captures the timeless charm of Old Florida, while offering unique potential for future development or multi-generational living. All within easy access to St. Petersburg, Tampa, and the I-275 corridor-yet worlds away from the ordinary.
