Buying a Home in Fairfax County, VA: A Buyer’s Guide

The short answer

Thinking about buying a home in Fairfax County, VA? Fairfax County is the largest jurisdiction in Northern Virginia and covers very different places, from Metro-centered Tysons and Reston to established single-family areas like McLean, Vienna and Great Falls, western communities like Herndon, Chantilly, Centreville and Clifton, and the Mount Vernon and Lorton areas to the south. In September 2026 the county’s median sold price was $749,750, up 5.6% from a year earlier, and active listings were up 35.6%, so buyers had more homes to compare than a year before (Bright MLS).

What are the main parts of Fairfax County to look at?

• Tysons and the Silver Line: condos, townhomes and some single-family streets near the Silver Line stations in Tysons, Reston and Herndon.
• McLean, Great Falls, Vienna and Oakton: mostly single-family neighborhoods, with larger lots in Great Falls.
• Reston and Herndon: planned communities around Reston Town Center and Lake Anne, and the Town of Herndon.
• Chantilly, Centreville and Clifton: townhomes, planned communities and larger wooded lots in the western part of the county.

Town, county or mailing address?

Most of Fairfax County is unincorporated, but Vienna, Herndon and Clifton are incorporated towns with their own town governments inside the county. Many mailing names, like McLean or Alexandria, are not separate governments at all. For any home, confirm the jurisdiction, because it affects taxes, rules and services.
