Key Colony Beach is its own compact island city just off Marathon, the kind of place where golf carts outnumber traffic lights and the water is never more than a block or two away. Nearby Marathon homes for sale share the same middle-Keys rhythm, but this stretch keeps a quieter, residential character with pockets like Coco Plum Terraces and Marathon Shores drawing buyers who want canal access without leaving the neighborhood.
The market here is thin and moves fast — there's currently a single active listing at $749,000, and homes that hit the market don't linger, with a median of just 1 day on market. Over the past year only 2 homes sold, at a median of $673,500, and sellers pulled in about 96% of asking. If you're serious, watch the live map closely; inventory this tight rewards buyers who are ready to move.
