Key Biscayne sits at the end of the Rickenbacker Causeway, a barrier island that trades the density of Miami-Dade County for beaches, bike paths, and a walkable village core. The island bookends itself with two state parks, and life here leans toward the water — which shows up in the housing, where waterfront homes and homes with water views dominate the inventory.

This is a genuine luxury market: the median list price is $2,775,000, and 114 of the 138 active listings are priced above $1M. Condominiums make up the bulk of what's for sale, so buyers browsing townhomes & condos will find far more choice than those hunting single-family homes. With homes sitting a median of 62 days and sellers netting about 95% of asking, there's room to negotiate without a bidding-war pace.

Key Biscayne is in Miami-Dade County, Florida.
