Homes for Sale in Key Biscayne: What to Know Before You Search
Beyond the Rickenbacker tollgate, tucked between two state parks, Key Biscayne functions as Miami's island village — a K-8 school and streets where children pedal to the beach. Ordinance limits the condo count and no new building has opened since 2014, which means the scarcity driving prices here is entirely real.
This page pulls the entire Key Biscayne for-sale market into one view — houses, condos and townhomes side by side — so you can weigh what the same budget buys across different forms of ownership. Key Biscayne is a market defined by a family island village between two state parks, fifteen minutes from Brickell, and buyers who track it as a whole rather than fixating on one building or subdivision tend to find the better deal in the category they never planned to shop.

Frequently Asked Questions
Is now a sensible time to buy in Key Biscayne?
It depends entirely on the segment — houses, condos and townhomes in Key Biscayne each run on their own supply-and-demand clock. The live tiles on this page report what actually closed over the past year and how long those sales took; ask us and we'll break down the exact slice you're weighing.
What do buyers relocating from another state need to know about Key Biscayne?
Florida charges no state income tax and shields a primary residence through homestead, but the diligence that matters most here is insurance and, for condos, the association's finances. We take every client through reserves, budgets and any pending assessment work before an offer goes in — never after.
How do I arrange a showing in Key Biscayne?
Each listing on this page carries an inquiry form that goes straight to our brokerage — or reach us at +1 786-370-8570. We schedule private tours to fit your calendar and run live video walkthroughs for buyers relocating from out of state, with no obligation attached.
