Loudoun County, Virginia

Loudoun County is just a stone’s throw from Washington D.C. Leesburg is the county seat. Money flows freely here. It’s one of the wealthiest counties in the nation. That wealth shows in the schools, which are top-notch.
Its eastern half is pure suburbia. Think cookie-cutter homes and strip malls. But head west and you’ll hit horse country. Rolling hills, historic estates, and wineries abound.
It’s a tech hub too. Data centers hum away in nondescript warehouses, powering much of the internet. Traffic can be a nightmare, especially on Route 7. But for many, the perks outweigh the hassles. Where else can you work a high-powered job and come home to your own little piece of countryside?
