Monroe County, Florida
Monroe County is the Florida Keys plus the mainland Everglades, running from Key Largo down US 1 to Key West. It carries the highest median home value in the state by a wide margin, and its market is set by law rather than demand: the Rate of Growth Ordinance caps new building permits outright, and nearly all mainland land is preserve — so permit allocations and elevation rules decide any site.
