Fairfax County remains a seller's market in February 2026, with 2.4 months of supply — still below the 3.0-month threshold that defines a balanced market. However, the data tells a more nuanced story that every seller needs to understand before listing. Cumulative days on market have risen from 28 in February 2025 to 54 in February 2026 — nearly double — which reflects a growing segment of homes that are stalling, relisting, and ultimately selling for less due to overpricing.
