If you have been watching the Loudoun and Fairfax housing market and wondering whether to wait, here is the November picture in one sentence: families have noticeably more homes to choose from than they did a year ago, and prices have held steady rather than dropping. That combination more choice, steady prices, and homes still selling in about a month is why this fall feels calmer than the frenzied markets of recent years, but it is not a bargain market either. Here is what the latest September 2026 numbers actually show, county by county, and what they mean if you are buying, selling, or doing both at the same time.
Across the Northern Virginia region tracked by the Northern Virginia Association of Realtors (NVAR) Fairfax and Arlington counties plus Alexandria, Fairfax City, Falls Church, Vienna, Herndon, and Clifton the September 2026 median sold price was $744,950, up 4.2% from September 2025. Active listings rose 30.7% year over year to 3,477, while closed sales fell 7.5% to 1,250. Homes averaged 28 days on market, unchanged from a year earlier, and supply stood at about 2.5 months up from a year ago, but still well below the five to six months usually considered a balanced market. In plain language: more homes are sitting on the market, fewer are closing each month, and prices have not fallen with them.
In Loudoun County, the September 2026 median sold price was $758,500, up just 0.8% from a year earlier. Closed sales fell 17.8% to 338, while active listings rose 34.1% to 1,031, and homes averaged 31 days on market. New contracts fell 26.0% to 336 the number worth watching, because it tells us how many buyers are actually committing right now, even when the median price looks steady. For families, the practical takeaway is that Loudoun has real breathing room again: you can tour, compare, and think, instead of deciding in a single weekend. The trade-off is that the homes that are priced right and show well are still moving; the extra inventory is not the same as unlimited time on every house.
In Fairfax County, the September 2026 median sold price was $749,750, up 5.6% from a year earlier, with 897 closed sales. New contracts fell 18.7% to 846, active listings stood at 2,326 at the end of September, and homes averaged 26 days on market. Fairfax is the larger, more varied market of the two — from townhouses and condos near Metro to large single-family homes in McLean and Vienna — so the countywide median hides a lot of neighborhood variation. What holds across Fairfax is the same pattern as Loudoun: fewer new contracts, more listings than last fall, and a median price that has risen rather than retreated.
If you are buying a home in Loudoun County or Fairfax County this fall, this is a more workable window than buyers have had in years — with a caveat. You have more choice and more room to negotiate than in the spring, when a much larger share of homes sold above asking. But mortgage rates remain the headwind: Freddie Mac's survey put the average 30-year fixed rate at 7.32% for the week ending October 22, 2026, so your monthly payment, not just the price tag, decides what is comfortable. Get pre-approved, know your payment ceiling before you tour, and be ready to move when the right house appears...homes are still selling in roughly four weeks on average, so preparation matters even in a slower market.
If you are selling a home in Fairfax County or Loudoun County, pricing and presentation matter more than they did when every listing drew a crowd. The homes drawing offers are the ones priced in line with recent comparable sales and ready to show on day one. Overpricing now tends to cost time, and time on market is the number buyers notice. If you are buying and selling at the same time the move so many Loudoun and Fairfax families are making - the order of operations matters even more: talk through selling first, buying first, a same-day close, or a rent-back before you list, so a slower contract pace does not leave you stuck between two homes.
One difference that still surprises families comparing the two counties is property tax. Loudoun County's real property tax rate is $0.805 per $100 of assessed value, while Fairfax County's rate is $1.12 per $100 for FY 2027. On the same assessed value, that gap adds up month after month, and it is one reason some families weigh a slightly higher Loudoun purchase price against a lower annual tax bill. Taxes are only one piece of the comparison....commute, schools, HOA dues, and the neighborhood itself matter just as much...but run the full monthly number, not just the sale price, before you choose a county.
November in Loudoun and Fairfax is not a crash, and it is not a boom. It is a steadier, choosier market: more homes for sale, fewer rushed decisions, prices holding near $750,000 at the median, and rates that reward buyers who have done their homework. If you have been waiting for a calmer moment to make a family move, this fall is worth a serious conversation just bring your payment ceiling, your timeline, and your must-haves to the table first.
