Welcome to 11295 6th Ave Gulf -- a waterfront corner lot in one of Marathon's best-kept-secret neighborhoods. Nestled on a quiet street directly across from a nature preserve, this 3-bedroom, 2-bath canal home delivers something almost impossible to find in the Keys: real privacy, real waterfront, and real potential.
Eighty feet of deep-water canal frontage on an oversized 8,000 sq ft corner lot. One canal from the Gulf of America with 10-minute access to Vaca Cut -- your gateway to world-class offshore fishing, diving, lobstering, and reef exploration. The spacious vaulted-ceiling screened porch overlooking the canal is where you'll spend every morning and evening. A 385 sq ft concrete dock with davits is ready for your boat. The corner lot provides ample parking for trailers, vehicles, and toys -- a true premium in the Keys.
This is also a performing investment property. The home operates as an active vacation rental on Airbnb and VRBO with verified income. Sold fully furnished and turnkey -- a new owner can generate income from day one.
Recent updates include a new 2025 HVAC system, 2025 impact sliding glass door, hurricane shutters on all windows, and all furnishings included. The home is solid, comfortable, and rental-ready as-is -- with room to add your own personal touches and make it truly yours.
For the visionary buyer: build up on this premium corner lot and you could be rewarded with Gulf of America views. An elevated waterfront home on this lot -- with a nature preserve across the street and 80 feet of canal -- would be one of the most compelling properties in Marathon.
The location is irreplaceable. The potential is limitless. Come see it.
