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.
Three-bedroom condos are where Key Biscayne buyers stop compromising — room for a family, a home office and guests without leaving the building's amenities and lock-and-leave ease behind. Known for a family island village between two state parks, fifteen minutes from Brickell, Key Biscayne keeps three-bedroom inventory tighter than the smaller plans, so the well-priced ones move quickly and often draw competing offers. This page narrows Key Biscayne condos to three bedrooms and up.
They're the scarcer end of most buildings' unit mix, which is why they hold value and turn over fast when priced right. We watch the towers that carry them and flag new listings before they're widely shopped.
Sometimes — a handful of Key Biscayne buildings allow unit combinations subject to board and structural approval, and it can be the only route to a large floor plan in a specific tower. We know which boards entertain it and what the process involves.
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.
