Fairfax County House Inventory Remains Elevated as September New Listings Increase | Fairfax County Inventory Tracker | September 8, 2026
Updated: 6 days ago
September began with the expected increase in Houses coming to market in Fairfax County—but without a corresponding increase in New Contract activity.
For the week ending September 6, 342 New Listings entered the Fairfax County market, compared with 228 New Contracts. New Listings have now exceeded New Contracts for 28 consecutive weeks.
At the same time, Fairfax County had 1,874 Active Houses, 20% more than at the comparable point in 2025.
The most important September question is therefore becoming clearer:
Will Buyer activity increase enough to absorb both the elevated inventory already on the market and the additional Fall listings now arriving?
September Brought the Expected Increase in New Listings
New Listings increased from 276 during the final week of August to 342 during the week ending September 6.
That increase was not unexpected. September normally brings renewed listing activity following the slower late-summer period.
What did not increase materially was Buyer activity.
Fairfax County recorded 228 New Contracts, compared with 218 the previous week. The latest number was also essentially equal to the comparable week in 2025.
This first week of September result makes the next 1-2 weeks particularly important as a gauge of the Fall market.
During September 2025, weekly New Contracts increased from 223 during the first week to 231, 245 and 260 during the following three weeks. Whether September 2026 produces a similar increase should provide an important indication of how readily the current inventory can be absorbed. However, even if we see a similar increase over the next weeks, the total level of Active House inventory will not unlikely to decline from the current high level if New Listings continue to outpace New Contract.
New Listings Have Exceeded New Contracts for 28 Consecutive Weeks
The latest week extended a pattern that has persisted since late February:
New Listings have now exceeded New Contracts for 28 consecutive weeks.
The September 6 difference was particularly large:
342 New Listings vs. 228 New Contracts.
Those two measures should not, however, be treated as a complete inventory equation. Houses also leave Active Inventory through withdrawals, cancellations, expirations, and Temporary Off Market status.
That distinction was particularly important this week.
Why Did Total Active House Inventory Decline Despite More New Listings Than New Contracts?
Fairfax County Active Inventory declined from 1,920 Houses on August 30 to 1,874 on September 6, even though New Listings exceeded New Contracts by 114 Houses.
A closer review of the weekly data provides important context.
During the week ending September 6, 249 Houses moved from Active into withdrawn, canceled, expired, or Temporary Off Market status. This number compares with:
116 during the previous week;
between 72 and 116 during each of the preceding four weeks; and
181 during the comparable week in 2025.
The latest figure therefore represents an unusually large number of Houses leaving Active status.
Some may remain off market. Others—particularly Houses temporarily removed or listings being repositioned—may return during September.
For that reason, the decline in visible Active Inventory should not be interpreted as evidence of increased Buyer activity.
Instead, some of the reduction may prove temporary.
Fairfax County House Inventory Remains Elevated
The more durable inventory observation is that Fairfax County continues to have substantially more Houses available than last year.
As of September 6:
1,874 Active Houses | +20% vs. 2025
The percentage is lower than the +33% year-over-year comparison reported one week earlier, but the actual inventory series tells the more useful story. The last week of August inventory comparison number was likely an anomaly due to market activity that occured in late August 2025.
Since mid-July, Fairfax County Active Inventory has remained within a relatively narrow range around 1,900 Houses. The late-August +33% comparison was magnified by a seasonal decline in the comparable 2025 inventory level.
The current +20% comparison therefore does not represent a major deterioration from the previous week. Fairfax County continues to enter the Fall market with an elevated inventory base.
Higher Inventory Remains a Northern Virginia Market Condition
The same condition extends beyond Fairfax County.
As of September 6, Active Inventory compared with 2025 was:
Locality | Increase vs. 2025 | Active Houses | Additional Houses |
Fairfax | +20% | 1,874 | +306 |
Alexandria | +21% | 365 | +63 |
Arlington | +5% | 445 | +23 |
Loudoun | +26% | 882 | +189 |
Prince William | +27% | 897 | +188 |
Stafford | +14% | 492 | +62 |
The magnitude varies considerably by locality, but every Northern Virginia jurisdiction tracked continues to have more Active Inventory than at the comparable point last year.
And 2025 itself was already an elevated-inventory comparison year.
For example, Fairfax County inventory during July and August 2025 was 40% and 31% higher than 2024, respectively, while September 2025 was 33% higher than September 2024.
The current market therefore is not simply mirroring last year's high inventory environment. It is operating above an already substantially higher 2025 inventory level.
Has Buyer Demand Weakened Enough to Explain the Higher Inventory?
Not based on the June, July, and August data.
Fairfax County New Contracts were modestly below 2025 during both halves of August—approximately 6–7% lower. Across the full month, that represented only 66 fewer Contracts across all property types and price points.
New Contracts in Fairfax County during June and July were essentially flat compared to 2025.
The evidence continues to support the broader market condition we have been tracking: Houses are accumulating partly because Buyers are taking longer to make decisions in a market offering substantially more choices.
September may provide an important new test of that conclusion.
If New Contract activity begins falling materially behind 2025 while New Listings remain elevated, weaker year-over-year Buyer activity could become a more significant contributor to inventory accumulation.
One week is not enough to establish that development.
Why the Next Few Weeks Matter
There are now three supply-and-demand variables worth watching together.
First, New Listings. The Fall listing cycle has begun, and the first week of September produced a substantial increase.
Second, New Contracts. The first week's 228 Contracts were essentially consistent with last year. The question is whether Contract activity increases during September as it did in 2025, as well as the magnitude of any increase compared to weekly New Listings.
Third, Houses temporarily leaving Active Inventory. If a meaningful portion of the unusually large number of Houses removed from Active status duing the first week of September returns to the market, that inventory will rejoin the new Fall listings already arriving.
Those variables will determine whether Fairfax County Active Inventory:
remains near its recent high range, begins declining through stronger Buyer absorption, or facing upward pressure as Fall supply outpaces Contract activity.
What Does the Current Market Mean for Sellers?
Buyers continue to have significantly more House options than they did a year ago.
For Sellers, however, countywide inventory is only the market environment.
The relevant competitive question is what Buyers see when they compare a particular House with the alternatives available in its micro-market, price range, and property type.
That makes pricing, presentation, and positioning particularly important when Buyers have enough alternatives to deliberate rather than act immediately.
The first week of September does not yet show a material deterioration in Buyer demand relative to 2025, but it also did not show an increase relative to recent weeks or in comparison to the number of New Listings coming to market.
However, it does establish the baseline for what may be one of the most informative periods of the Fall market.
Bottom Line
Fairfax County started September with 1,874 Active Houses—20% more than last year—as New Listings increased substantially while New Contract activity remained flat compared to both the end of August and first week of September 2025. An unusually large number of Houses also left Active status during the week, meaning the slight decline in total Active House inventory may prove temporary. The next 1-2 weeks should show whether Buyer activity strengthens enough to absorb some of the new Fall inventory, whether recently removed Houses return to the market, and if we see upward pressure on total Active House inventory from Buyer activity that continues to be outpaced by New Listings.
Frequently Asked Questions
Why did Fairfax County Active House inventory decline even though New Listings exceeded New Contracts?
Active Inventory declined from 1,920 Houses on August 30 to 1,874 on September 6, even though there were 342 New Listings and 228 New Contracts. New Listings and New Contracts do not form a complete inventory equation. Houses also leave Active status through withdrawals, cancellations, expirations, and Temporary Off Market status.
Did increased Buyer activity cause Fairfax County inventory to decline?
The current data do not support that conclusion. New Contracts totaled 228 during the week ending September 6, essentially flat with the prior week and the comparable week in 2025. At the same time, 249 Houses moved from Active into withdrawn, canceled, expired, or Temporary Off Market status, substantially more than during recent weeks. These Houses moving off market were responsible for the slight decline in total Active House inventory.
Could some of the September decline in Active Inventory be temporary?
Yes. Some Houses that moved out of Active status may return to the market, particularly those placed in Temporary Off Market status or subsequently relisted. It is not yet known how many will return. The unusually high number of off-market changes means the decline in visible Active Inventory should be interpreted cautiously.
Is Fairfax County House inventory still significantly higher than last year?
Yes. Fairfax County had 1,874 Active Houses on September 6, 2026, approximately 20% more than at the comparable point in 2025. Inventory has remained within a relatively narrow, elevated range since mid-July despite week-to-week changes in the year-over-year percentage comparison.
Is elevated Active Inventory limited to Fairfax County?
No. Active Inventory remained above 2025 across all six Northern Virginia localities tracked as of September 6. The increases ranged from 5% in Arlington to 27% in Prince William County, indicating that higher inventory remains a broader Northern Virginia market condition. For context, inventory in 2025 was already elevated above the prior year. In Fairfax County, Active House inventory in July, August, and September 2025 was up 40%, 31%, and 33% vs. 2024.
What should Northern Virginia Sellers watch during September?
The key question is whether Buyer activity increases as additional Fall listings enter the market. New Contracts were essentially flat with 2025 during the first week of September. If Contract activity strengthens, it could help offset some of the added inventory through New Listings. If New Listings continue substantially outpacing New Contracts—particularly if recently removed Houses return—Active Inventory could increase from the already high level.
