Fairfax County Buyer Activity Shifts Back Toward New Listings as Extended Days on Market Inventory Reaches a 2026 High | Northern Virginia Market Update | September 10, 2026
Buyer activity in Fairfax County shifted toward Houses with longer Days on Market during July through mid-August. Over the past two weeks, that pattern has moved back toward recently listed Houses.
From August 26 through September 8, 54% of Fairfax County New Contracts involved Houses with 14 Days or less on market, compared with 29% involving Houses with 30+ Days on Market.* The resulting Buyer Activity Ratio has risen back to nearly 2 to 1 in favor of recently listed Houses.
This change in Buyer activity has not reduced the large inventory of Houses already carrying extended Days on Market, as the total amount of weekly New Contracts continues to trail New Lisitings. Further, the New Contracts activity at the start of September has not increased over August, with a noticeable lag to New Contracts activity from early September 2025. The links are to the September 8, 2026 Fairfax County Inventory Tracker post which looks at weekly Active Houses vs. New Listings vs. New Contracts.
As of September 9, 58% of Fairfax County Active Houses had 30+ Days on Market and 34% had 60+ Days. Across the broader Northern Virginia market segment, the numbers were similar: 59% at 30+ Days and 35% at 60+ Days.
These are the highest extended Days on Market shares recorded so far in 2026.
The result is an important market distinction for Sellers: where Buyers are currently concentrating their activity is changing, but the inventory accumulated during the slower summer decision cycle remains.

Buyer Activity Has Shifted Back Toward Recently Listed Houses
During July through mid-August, Fairfax County Buyer activity progressively moved more attention toward Houses that had been on the market longer.
The weekly New Contract data show how significant that change became.
In early July, only 18% of New Contracts involved Houses with 30+ Days on Market. That share increased through August, eventually reaching 35% during August 19–25.
At the same time, the share of New Contracts involving Houses with 14 Days or less on market declined from 64% in mid-July to 43% during two August weeks.
The past two weeks have moved in the opposite direction:
August 26–September 1: 54% ≤14 Days versus 30% at 30+ Days.
September 2–8: 53% ≤14 Days versus 28% at 30+ Days.
The increase in New Listings during the first week of September may be contributing to this shift by giving Buyers a larger selection of newly listed Houses to consider.
It is too early to determine whether this represents another sustained change in Buyer behavior. But for now, Buyer activity has clearly become more concentrated among recently listed Houses than it was during August.
The Buyer Activity Ratio Has Risen Back to Nearly 2 to 1
Looking at the most recent two-week tracking period provides another way to measure the change.
Among Fairfax County Houses going Under Contract from August 26 through September 8:
54% had 14 Days or less on market.
29% had 30+ Days on Market.
That produces a Buyer Activity Ratio of approximately 1.9 to 1—nearly two recently listed Houses going Under Contract for every 30+ Day House.
This is a meaningful increase from late August, when the ratio had narrowed to approximately 1.3 to 1.
But the ratio does not mean Buyers have stopped purchasing Houses with longer Days on Market. Nearly three out of every ten recent New Contracts still involved a House with 30+ Days on Market.
Instead, the data indicate that the relative concentration of Buyer activity has shifted back toward newer inventory.
A Significant Market Imbalance Remains
The more consequential issue may be what is happening on the Supply side of the equation.
While 29% of recent Fairfax County New Contracts involved Houses with 30+ Days on Market, 58% of the Active Houses available to Buyers were already in that segment as of September 9.
That creates a substantial imbalance between the composition of Active Inventory and where Buyer activity is occurring.
The same pattern exists at 60+ Days on Market. 34% of Fairfax County Active Houses had been on market for at least 60 days, while only 15% of recent New Contracts involved Houses in that segment.
This helps explain why extended Days on Market inventory can remain elevated even while Buyers continue purchasing older listings at a higher share than in June or July.
There are simply substantially more longer Days on Market Houses competing for the portion of Buyer activity reaching that segment.
58% of Fairfax County Active Houses Now Have 30+ Days on Market, with One Third Having 60+ Days
The early September Fairfax County Active House inventory data show that the percentage shares of long Days on Market Houses continue to remain at a high point for the year.
As of September 9, among the 889 Active Houses*:
24% had 14 Days or less on market.
71% had 21+ Days on Market.
58% had 30+ Days.
34% had 60+ Days.
Time on market within these longer Days on Market segment remains substantial.
The 21+ Day segment had a 57-day median and 72-day average.
For Houses with 30+ Days, the median was 65 days and the average 82 days.
Houses with 60+ Days had a 92-day median and 109-day average.
In practical terms, the average 30+ Day House has now been on the market for nearly three months, while the average 60+ Day House is approaching four months time on market, with these segments accounting for a clear majority of all Active Houses.
The First 2–3 Weeks Remain the Market Tipping Point
The latest data continue to support an important pattern observed throughout 2026: the first 2–3 weeks represent a critical Market Tipping Point for a House.
Only 24% of Fairfax County Active Houses were within their first 14 Days on Market on September 9.
Yet those recently listed Houses accounted for 54% of New Contracts during the preceding two weeks (August 26-September 8 period).
Further, 71% of Active Houses have 21+ Days on Market, with a 2+ month average time on market.
That does not mean a House that passes 14 or 21 Days cannot sell. The July and early August data demonstrate the opposite: Buyer activity can and does shift toward older inventory, although the strength of this shift in Buyer activity is lessening over the past 2-3 weeks.
What changes is the competitive environment.
A House that does not secure a Buyer during its early exposure period moves into an increasingly large inventory segment where more Houses are competing for a smaller relative share of current Buyer activity.
For Sellers, that makes pricing, preparation, presentation, and positioning at launch particularly important. The objective is not simply to enter the market. It is to establish the House as a preferred choice while Buyer attention is most concentrated.
Longer Days on Market Is a Northern Virginia Condition
The Fairfax County pattern is not isolated.
The Northern Virginia market segment tracked by Bella Casa Partners includes Fairfax and Arlington Counties and the Cities of Alexandria, Fairfax, and Falls Church.
As of September 9, there were 1,113 Active Houses ≤$2 million, excluding condos and new construction.
Of those Houses:
71% had 21+ Days on Market.
59% had 30+ Days.
35% had 60+ Days.
The overall market had a 41-day median and 55-day average Days on Market.
For Houses already at 30+ Days, the median had reached 66 days and the average 83 days.
At 60+ Days, the median was 93 days and the average 111 days.
The similarity between the Fairfax County and broader Northern Virginia numbers is notable. It indicates that extended Days on Market is not simply the result of a few Fairfax County neighborhoods or isolated property segments. It is part of the broader market environment confronting Sellers across Northern Virginia.
Is Early September Buyer Activity Beginning to Lag 2025?
The large number of Houses already carrying extended Days on Market makes overall Buyer activity one of the most important data points to watch as the Fall market develops.
Through the summer, Fairfax County New Contract activity generally tracked reasonably close to 2025, even as Buyers took longer to decide which House to purchase. August New Contracts finished only modestly below last year.
Early September looks different.
For September 1–8, Fairfax County New Contract activity was:
All property types and all price points:
2026: 215 New Contracts
2025: 274 New Contracts
Houses ≤$2 million, excluding condos and new construction:
2026: 158 New Contracts
2025: 191 New Contracts
Those are meaningful year-over-year differences, but it is too early to conclude that they represent a deterioration in Buyer activity.
There is an important calendar issue in the comparison. Labor Day fell on September 1 in 2025 and September 7 in 2026. The September 1–8 periods therefore capture the holiday at very different points, and some 2026 Buyer activity may simply have been deferred by the later Labor Day weekend.
That makes the next full week of New Contract data particularly important.
If Contract activity rebounds toward the 2025 level, the early September gap may prove to have been primarily a calendar effect. If New Contracts remain materially below 2025, however, it would provide stronger evidence that a year-over-year Buyer activity gap may be developing.
That distinction matters because the market is already carrying substantial extended Days on Market inventory. In Fairfax County, 58% of Active Houses have 30+ Days on Market and 34% have 60+ Days.
If September New Contract activity remains materially below last year while New Listings continue their expected seasonal increase, the current elevated inventory level could face additional upward pressure. That pressure could be amplified if some of the Houses recently removed from Active status return to the market.
The next several weeks should therefore help answer an important Fall market question: Will Buyer activity be sufficient to absorb both new September inventory and the substantial inventory already carrying extended Days on Market, or will Active House inventory face upward pressure with New Contracts lagging New Listings?
What Does This Mean for Northern Virginia Sellers?
The countywide and regional data establish the market environment. They do not determine the outcome for an individual House.
A Seller's actual competitive environment is the micro-market in which Buyers will compare that House with available alternatives.
But the broader data make one point increasingly clear: Sellers are operating in a market where Buyers have substantial choice and where a large percentage of competing Houses have already accumulated significant market time.
That increases the importance of understanding the competitive set before going Active and positioning the House to capture Buyer attention from the beginning.
Once a House moves beyond the initial 2–3 week Market Tipping Point, the data show that the competitive environment becomes materially different.
Bottom Line
Buyer activity in Fairfax County has shifted back toward recently listed Houses, but the extended Days on Market inventory accumulated during the summer remains at its highest level of 2026.
As of September 9, 58% of Fairfax County Active Houses had 30+ Days on Market, with nearly a 3 month average time on market, compared with only 29% of recent New Contracts involving Houses in that segment. The broader Northern Virginia market shows essentially the same pattern.
There is now another data point to watch. Early September New Contract activity is running below 2025, although the different timing of Labor Day makes it too early to determine whether that gap reflects a calendar effect or the beginning of weaker year-over-year Buyer activity.
That distinction could be important for the Fall market. If New Contract activity remains materially below 2025 while New Listings continue to enter the market, lower Contract volume could become an additional source of upward pressure on inventory already carrying extended Days on Market.
For Sellers, both the current concentration of Buyer activity and the possibility of a changing supply-demand balance reinforce the importance of the initial market launch. Pricing, preparation, presentation, and strategic positioning before a House goes Active remain critical to competing for Buyer attention during the first 2–3 week Market Tipping Point.

Frequently Asked Questions
Are recently listed Houses receiving more Buyer activity in Fairfax County?
From August 26 through September 8, 54% of Fairfax County New Contracts involved Houses with 14 Days or less on market, compared with 29% involving Houses with 30+ Days on Market. This represents a shift back toward newer inventory after Buyer activity moved toward longer Days on Market Houses during August.
Are Houses with 30+ Days on Market still selling in Fairfax County?
Yes. 29% of Fairfax County New Contracts from August 26 through September 8 involved Houses with 30+ Days on Market. However, 58% of Active Houses were in that segment as of September 9, meaning 30+ Day Houses represent a substantially larger share of available inventory than of recent Contract activity for these Houses.
How much Fairfax County inventory has longer Days on Market?
As of September 9, 71% of Fairfax County Active Houses had 21+ Days on Market, 58% had 30+ Days, and 34% had 60+ Days. Houses in the 30+ Day segment averaged 82 Days on Market, while the 60+ Day segment averaged 109 days.
Is extended Days on Market inventory limited to Fairfax County?
No. The broader Northern Virginia market shows almost the same pattern. As of September 9, 71% of Active Houses had 21+ Days on Market, 59% had 30+ Days, and 35% had 60+ Days across the Northern Virginia market segment tracked in this analysis.
Is Fairfax County Buyer activity beginning to fall below 2025?
Early September New Contract activity is below 2025, but it is too early to determine whether this represents weaker Buyer activity. Labor Day occurred on September 1 in 2025 and September 7 in 2026, making the September 1–8 periods difficult to compare directly. Additional September Contract data should provide a clearer indication.
Why will September New Contracts activity matter for Northern Virginia Sellers?
The market already has substantial longer Days on Market inventory. If New Contracts remain materially below 2025 while Fall New Listings continue entering the market, lower Contract volume could add further upward pressure on inventory. For Sellers, that would increase the importance of competitive pricing, preparation, presentation, and positioning during the initial weeks on market.
