About this property
Exceptional canal-front opportunity with proven income potential. This expansive 7-bedroom, 7-bath residence offers outstanding flexibility as a legal duplex with an interior lockout, allowing it to function seamlessly as a large single-family home or as two separate living spaces. The configuration includes a generous 5BR/4BA main residence paired with a private 2BR/2BA guest wing, topped off by a convenient pool bath located in the game room, making it ideal for multigenerational living, guests, or vacation rental use. The main living space welcomes you with a dramatic two-story entry, an open-concept great room, multiple dining areas, wet bar, and a well-appointed kitchen that flows to a waterside balcony. The lower-level unit features its own open living and kitchen area, providing privacy and versatility. Four bedrooms are ensuite, complemented by 2 primary suites overlooking the water. Recent upgrades include complete concrete spalling repairs and a fresh exterior repaint, adding peace of mind and refreshed curb appeal. Mediterranean-inspired design elements are carried throughout, along with impact windows and doors, multiple balconies, and inviting indoor-outdoor living spaces. Outside, enjoy a heated pool, spa, covered poolside lanai, and 75 feet of concrete dockage with quick boating access to both the Atlantic Ocean and the Gulf of America. Additional features include a two-car garage and ample off-street parking. This property has a strong, established vacation rental history and is currently an active rental.
