St. Johns County, Florida
St. Johns County is among the fastest-growing and highest-income counties in Florida, running from historic St. Augustine north through Ponte Vedra Beach and the Nocatee master-planned community into Jacksonville's southern suburbs. Top-ranked schools drive relentless rooftop demand, and school attendance boundaries move value here more than almost anywhere else in the state.
