Seminole County, Florida
Seminole County is Orlando's affluent northern suburb, built around the Lake Mary and Heathrow corporate corridor, the UCF-adjacent growth in Oviedo, and Sanford's revitalized riverfront downtown. A strong school system and a rural boundary that has held for decades mean most opportunity here is redevelopment and infill rather than new ground.
