0 Avenue M, Marathon, FL 33050

$199,000
Property Type: Vacant Land Lot Size (sq. ft.): 12,197 Status: Active
Current Price: $199,000 List Date: 4/24/2026 Last Modified: 4/30/2026

Description

This is a property for someone thinking about the future, not just today. The lot measures 110' x 110' (just over a quarter acre), is cleared, and sits on a 100-foot-wide, boatable canal with quick access to open water. It's directly across from Cocoplum Beach, giving it a quiet, natural setting that's hard to find. You'll notice there are already homes on this street, including next door, and the two streets leading in show a similar pattern -- one side built out, the other still open. These larger parcels create space, privacy, and a peaceful feel tucked away from US-1. As it stands today, the lot does not meet current density requirements to be built on as a standalone parcel. A site condition letter from the City will be obtained and provided so buyers have a clear understanding of its current status. There are also three adjoining privately owned lots. While there are no guarantees, a future owner could explore the possibility of assembling multiple parcels or changes over time that may affect what's allowed. This is best suited for someone who understands the current limitations, doesn't need to build right away, and sees value in holding a unique piece of property for the long term.
