Description

Spacious and sophisticated waterfront home situated on a wide canal with desirable eastern exposure, offering serene views of the in-ground pool and 100-foot-wide canal. Designed for both entertaining and everyday comfort, the home features a covered patio on the lower level and a generous wooden deck on the upper level, connected by elegant spiral stairs leading to a dedicated entertainment area below. The newly updated upstairs kitchen is bright, modern, and exceptionally spacious, anchoring the upper-level living space. This five-bedroom, three-bathroom residence is thoughtfully laid out with two bedrooms and two bathrooms upstairs, and three bedrooms with one bathroom downstairs--ideal for extended family, guests, or rental flexibility. A circular paver driveway provides ample parking, while separate living areas on each floor enhance privacy and functionality. The Corian kitchen, expansive layout, and waterfront lifestyle make this property suitable as a large family home, corporate retreat, or high-performing vacation rental. Complete with a private boat lift and quick access to the Atlantic Ocean, this home delivers the full waterfront experience--whether as a permanent residence or an income-generating investment.

Navigation note: Navigation routes show the shortest mapped path to open water. A vessel taller than the binding bridge clearance may still reach open water via a longer alternate route that we don't currently map. Verify navigability with a local captain or surveyor before relying on it.
