Nassau County, Florida
Nassau County occupies Florida's northeast corner between Jacksonville and the Georgia line, pairing the historic port and resort market of Amelia Island and Fernandina Beach with fast-growing mainland communities at Yulee and Callahan. Its growth is driven by Jacksonville commuters and the master-planned Wildlight development along I-95, which makes school attendance zones and utility service boundaries decisive for residential land west of the Intracoastal.
