The island town of Key Biscayne may seem captivating for its stunning beaches, spectacular views, and nature preserves, but it is not a retirees’ paradise. The cost of living index for the island is 200.1, 100% higher than the state average. Median listing home prices, as of April 2023, have been hovering around $2.1 million, with median rents for properties standing at $7,900. Key Biscayne is also considered Zone A for hurricanes. Since 1930, more than 70 hurricanes have hit the area, making it a very high-risk zone. Overall, the island beach is generally safe to live in, with crime rates lower than the national average. Retirees must, however, have big nest eggs to consider living here.
