Key Biscayne: The Quiet Math of Island Living
A short causeway, a different way of life. Why families and second-home owners keep choosing the island — and what it actually costs to live there.
Cross the Rickenbacker once and you understand why people stay. Key Biscayne reads as a small island village in a way nowhere else in Miami quite manages — and that scarcity is what makes the math interesting.
Single-family inventory is genuinely thin. A handful of streets see only a few transactions a year, and well-positioned condos in the village center move on a private list before they ever reach the broader market.
