9775 78TH AVENUE, Seminole, FL, 33777 | $924,000

Under contract-accepting backup offers. A rare opportunity to own a private estate in the heart of Pinellas County—offering space, flexibility, and breathtaking natural surroundings. This exceptional property provides a unique combination of privacy, usable land, and lifestyle versatility, with an adjacent vacant lot also available for purchase separately. For buyers seeking even more room to expand, the seller is offering a reduced bundled purchase price when both parcels are purchased together, thus allowing you to create a more expansive private lakeview estate spanning just over an acre.
This custom-built, all-concrete two-story home is thoughtfully designed and ideally positioned with southern exposure, filling the home with natural light while capturing stunning sunset views over Lake Seminole Park.
Inside, the home offers a spacious and functional layout designed for everyday living and entertaining. The updated kitchen features solid wood maple cabinetry, granite countertops, a center working island, and a breakfast bar flowing seamlessly into the main living areas. Additional highlights include a wet bar with built-in wine rack, a wood-burning fireplace, numerous built-ins, and an expansive laundry room with utility sink.
The luxurious primary suite features vaulted ceilings, dual walk-in closets, and private access to a screened balcony where you will enjoy peaceful water views, vibrant sunsets, and abundant birdlife. The spa-like ensuite bath includes a jetted tub, dual sinks, and a large walk-in shower.
With four additional bedrooms and a dedicated den/study, this 5-bedroom, 3. 5-bath home offers incredible flexibility for everyday living, guests, or multi-generational needs. A private first-floor bedroom with full bath is ideal for extended family, visitors, or a private home office setup. The 3-car garage adds valuable storage and functionality for buyers seeking both convenience and space.
Step outside to your own resort-style oasis, complete with a large enclosed pool and spa featuring a waterfall, rock accents, PebbleTec finish, saltwater chlorine generator, and an elevated design. The expansive fenced yard, shaded by majestic oak trees, offers a tranquil, park-like setting, while the corner-lot layout provides multiple points of yard access and even more usable outdoor space. The xeriscaped front yard offers beauty with low maintenance, and the shallow well is ready for irrigation setup.
Built for both comfort and durability, the home had no water intrusion during recent hurricanes and features an 8-foot-deep foundation, two 200-amp electric panels, high-efficiency performance with low power bills, and two staircases for added convenience and safer exits. Significant updates include a new roof (2025), fully rescreened lanai and upstairs enclosure (2025), AC systems (2023), water heater (2024), and new pool pump and filter (2026).
Ideally located in the Lake Seminole area, the property is adjacent to Lake Seminole Park, where residents can enjoy trails, playgrounds, fishing, waterfront views, and boat ramp access, all while remaining close to shopping, dining, everyday essentials, top local conveniences, and just 10 to 15 minutes from the Gulf beaches.
