Key Biscayne is an island village reached only by the Rickenbacker Causeway, and that single point of access shapes everything about its real estate. The market splits cleanly into oceanfront condos along Ocean Drive and Crandon Boulevard and single-family homes on the interior village streets. The condo towers, many built in the boom decades and several recently renovated or rebuilt, command serious prices for direct ocean exposure, and a number of them sit behind guard gates with resort-level amenities. The single-family side ranges from original 1950s and 1960s ranch homes on generous lots to new contemporary builds, with the highest values on the canal and bayfront streets that offer dockage and open-water access. Even modest interior homes carry premiums that reflect the scarcity of land on a finite island. There is essentially no new raw land, so single-family growth happens almost entirely through teardown and rebuild.

Within the village, buyers learn the geography quickly. The gated communities and the streets closest to the bay, including the canal-front blocks, sit at the top of the single-family hierarchy. The interior grid near the village center puts residents within walking or biking distance of the shops, restaurants, and the K-8 community school, which is a major draw for families. Crandon Park anchors the north end of the island with its beach and tennis center, and Bill Baggs Cape Florida State Park with its lighthouse occupies the southern tip, so a large share of the island is permanent green and beach space rather than development. The condo corridor along the ocean is its own world, with buildings ranging from older co-ops to glassy newer towers, and the differences in dues, reserves, and rental rules between them are significant.

The island appeals to a buyer who wants an insulated, walkable, family-oriented community within fast reach of downtown Miami and Brickell, which sit just across the causeway. That commute is the practical trade: the Rickenbacker is the only way on or off, and storms or events can choke it. Insurance and flood considerations are front of mind, since the entire island is low and coastal, and condo buyers should study each building's reserve studies and any recent or pending assessments closely given Florida's structural recertification requirements. The school reputation, the low-key village feel, and the genuine sense of safety keep demand resilient, but buyers should go in clear-eyed about hurricane exposure, the cost of windstorm coverage, and the reality that nearly everything trades at an island premium.
