How Do Fairfax and Loudoun Housing Numbers Compare in Fall 2026?

How do the Fairfax County and Loudoun County housing markets compare right now?
Prices are close. Fairfax's median sale price was $750,000 and Loudoun's was $775,000 from July to September 2026. Loudoun had fewer sales than a year ago, and both counties now have more homes for sale than last fall.

The Mike Webb Team (Mike and Claudia Webb, RE/MAX Allegiance) helps homeowners in Arlington, Northern Virginia, Maryland, and Washington, DC get their homes ready to sell and sold.

These numbers come from the Bright MLS Industry Watch for Q3-2026, current as of October 10, 2026. Changes are from Q3-2025.

• Fairfax County: median sale price $750,000 (up 0.7%), 3,058 closed sales (down 4.4%), 28 days of average marketing time (down 0.9%), 98.7% of original list price received, 2.4 months of supply (unchanged).
• Loudoun County: median sale price $775,000 (up 2.4%), 1,307 closed sales (down 12.9%), 33 days of average marketing time (down 8.9%), 98.4% of original list price received, 2.6 months of supply (up 8.3%).

Fairfax closed more than twice as many homes as Loudoun in the quarter, 3,058 to 1,307. Loudoun's sales fell by a larger share, but its homes sold a little faster than a year ago, while Fairfax's time on the market was about the same.

Bright MLS's September 2026 Market Statistics Reports, printed October 14, 2026, show:

• Fairfax: 902 homes sold for $818 million combined, a median sold price of $749,750, and 26 days on market. In August, 982 sold. About 1,541 homes were newly listed in September, and 2,685 were for sale at the end of the month.
• Loudoun: 344 homes sold for $289 million combined, a median sold price of $750,000, and 31 days on market. In August, 446 sold. About 649 homes were newly listed, and 1,173 were for sale at the end of the month.

In both counties, more homes were listed in September than sold, so the number of homes for sale grew. That is one reason buyers have more choices than they did a year ago.

In September 2026, the median listed price was $750,000 in Fairfax and $775,000 in Loudoun. The average sold price was $907,255 in Fairfax and $840,042 in Loudoun. The average sits well above the median in Fairfax because a group of higher-priced sales pulls it up, so the median is the fairer yardstick for a typical home. Both come from the same Bright MLS reports.

Each report also compares months of supply, which is how long the homes for sale would last at the current pace of sales. For October 2026, Fairfax shows 3.0 months, up from 2.1 in October 2025, with 2,700 homes for sale versus 2,119. Loudoun shows 3.4 months, up from 2.0, with 1,181 homes for sale versus 869.

The Bright MLS | T3 Home Demand Index, October 2026 report, rated Fairfax 93, "Steady," and Loudoun 89, "Slow." The whole Washington-area report was 87, "Slow." The index counts showings and online home views, so it shows interest before homes sell. Source: Home Demand Index.

The quarterly Industry Watch and the monthly Market Statistics Report measure different periods. The quarterly report covers July to September, and the monthly report is a snapshot of one month. Compare each number to its own year-ago number, never one report to the other.

Buyers have more choices than a year ago, so price and condition matter more. A median is not a value for your home. Online and preliminary estimates are starting points. A property's potential market value depends on its condition, location, features, competition, market conditions, and other factors. Through The White Glove Home Sale Method, we handle painting, repairs, staging and deep cleaning at no additional cost to you, whatever the price or type of home.
