Takeaways
- Marathon is the broadest Middle Keys market — best entry point for primary residents and first-time VR investors.
- Key Colony Beach is tightening; days on market compressing and list-to-sold ratios firming up.
- Duck Key is small but premium — inventory is often off-market; buyers should set up alerts and be ready.
Commentary
Marathon continues to be the Keys' most balanced market. You can find primary-residence inventory, VR-permitted investor plays, waterfront with real dockage, and condo product all in a compact geography. Q1 DOM compressed from 80+ days in Q4 2025 to the mid-60s.
Key Colony Beach tightened meaningfully. The walkable-island dynamic is self-reinforcing — buyers who want that lifestyle won't substitute for nearby Marathon proper. Correctly priced KCB inventory sold inside of 50 days.
Duck Key inventory was thin. The combination of gated-community deed restrictions and strong Hawks Cay-adjacent demand keeps the pool small. Buyers with patience and a working relationship with an agent (hi, Gracie) catch these when they land.
