Redfin's rolling three-month median through September corroborates at about $748,000, up 4.6%, with an average of about 40 days on market, up from 38 a year earlier, and Zillow's average county value is about $756,000, up 1.2%. NVAR's regional September report shows the Northern Virginia median at $744,950, up 4.2%, with active listings up 30.7% year over year, and a verified county-level sale-to-list ratio for September or October was not published. The 30-year fixed mortgage rate averaged 7.18% for the week ending November 5, 2026 (Freddie Mac), its third straight weekly decline.

For buyers, inventory up about 36% year over year means real selection and room to negotiate, while prices remain firm, so a prepared, pre-approved approach still wins the best homes. For sellers, with 846 new pending contracts down 18.7% from a year earlier and supply well up, accurate pricing from day one and professional presentation are essential, while homes priced to the current data and marketed broadly are still seeing strong results.
