Duck Key is a cluster of residential islands in the middle Florida Keys, where life runs on canal water, dock lines, and the slow rhythm of a boating town. The homes here are almost entirely single-family homes built for direct water access, and the appeal is simple: step off your back patio and you're on the water, part of the wider Monroe County archipelago.
The market right now is extraordinarily thin. There is a single active listing on the island, priced at $4,500,000, which tells you how rarely property changes hands and how much a waterfront position in the Keys commands. Buyers should expect to move fast when inventory appears — it's worth watching both new listings and any just reduced opportunities closely.
Duck Key is in Monroe County, Florida.

Straight answers
Duck Key real estate FAQs
Is Duck Key a good place to live?+
It suits buyers who want a quiet, water-centered life in the middle Keys rather than a busy town scene. The island is residential and built almost entirely of single-family homes with direct water access, which is exactly its draw.
Is Duck Key expensive?+
Yes — it's one of the pricier addresses in the Keys. The single active listing sits at $4,500,000, and homes here average about $1,718 per square foot, so this is a high-end waterfront market.
What do homes cost in Duck Key?+
Right now the only active home is listed at $4,500,000 for roughly 2,620 square feet. Inventory is extremely limited, so pricing reflects the rarity of waterfront property across Monroe County.
How is the Duck Key market?+
It's thin and fast-moving. With a single active listing and a median of just one day on market, well-priced homes don't sit — buyers should be prepared and keep an eye on open houses this week.
What about HOA fees and property taxes?+
HOA data isn't available for the current inventory, but property taxes run high in line with values — the median is about $20,458 per year. Budget for those carrying costs alongside insurance when you plan a waterfront purchase here.
