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.

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.
