Last month in Reston, detached homes averaged nine days on market and sold for 102.3 percent of what sellers originally asked. Over the same 31 days, condos averaged 26 days and settled for 98.3 percent of their original price.
Same town. Same buyers driving the same streets. Two completely different markets.
That gap explains most stalled listings around here. Most advice about why homes do not sell assumes a market that behaves as one thing. Reston in 2026 does not. Neither does Herndon. Before you repaint anything or fire anyone, find out whether your listing is underperforming or simply moving at the normal pace for its segment.
First, check whether you actually have a problem
Bright MLS data puts normal for Reston in July 2026 at the following.
Detached homes: median sale price of $1,106,625, nine days on market, 102.3 percent of original list price, 23 active listings at month end.
Townhouses: median of $709,000, 13 days on market, 56 active listings, which is up 60 percent from the 35 available last July.
Condos: median of $391,000, 26 days on market, 98.3 percent of original list, and 108 active listings against a five-year July average of 59.
Hold your own situation against the right line. A detached home in Reston that has not drawn an offer in three weeks signals a real problem. A condo at day 24 is running on schedule. Sellers in the second group frequently panic, cut the price, and give away money they did not need to give away.
Herndon tells a similar story from a different starting point. Across the 20170 zip code, the median sale price sat at $719,837 for the three months ending in June 2026, up a fractional 0.3 percent year over year, with a median of 32 days on market. That is seven days slower than the same period a year earlier. Homes still sold at 100.7 percent of list, and 47.6 percent went above asking. Slower, but not soft.
The regional picture matches. NVAR reported 3,025 active listings across Northern Virginia in July, up 19.6 percent from a year earlier, with a median sold price of $750,000, down 1.3 percent year over year, and 21 days on market, up 5 percent. The growth was not evenly spread. Condo inventory rose 41.1 percent and attached homes rose 33 percent, while detached inventory actually fell 2.5 percent. NVAR’s own read was that the headline inventory figure hides a “more nuanced story,” because nearly all of the added supply arrived in condos and attached homes. Regional months of supply rose to 2.13, up 14.8 percent year over year, and still short of what most economists would call balanced.
The ten reasons listings stall around here, ordered by how often they actually bite:
1. You priced against the town, not against your segment
The Reston median across all home types was $630,000 in July, up 4.1 percent from a year earlier. That number is real and it describes almost nobody. It sits between a detached segment climbing around six percent a year and a condo segment falling around seven percent, and it lands on a figure that applies to neither.
If your agent built a comparative market analysis on town-wide trends, that analysis averaged two markets moving in opposite directions. Ask instead for the last six months of closed sales in your specific property type, in your specific price band, ideally in your cluster. In Reston that means your actual cluster, because a townhouse backing to a wooded common area in Hunters Woods and one facing a parking court in North Point are not comparable, whatever the square footage says.
2. You are competing with far more listings than you think
Reston finished July with 187 active listings across all home types, which is 72 percent above the five-year July average. Every single segment hit its highest July inventory count in the five-year record.
The concentration matters more than the total. Of the 108 active condos, 90 sat in the $200,000 to $499,999 range. Those same price bands produced 26 of the month’s 40 condo sales. That works out to about three and a half months of supply within those bands, and it means your unit is one of dozens that look nearly identical in a search results grid.
Detached sellers are in the opposite position. Fourteen detached homes priced above $1 million sold in July, and 14 sat on the market at month end. One month of supply. If you own in that band and you are not getting showings, the market is not your problem.
3. Your photos lose the scroll
This mattered in 2021 and it matters more now, for an unglamorous reason. When a buyer filters for Reston condos between $300,000 and $399,999, they get a wall of thumbnails. Most of those units have the same floor plan, the same balcony, and the same beige carpet. The photograph is the entire competitive advantage.
Blurry, dim, or badly ordered photos are the obvious failure. The subtler one is leading with a shot of the building exterior. Nobody falls in love with a mid-rise facade. Lead with your strongest room, whether that is a light-filled living room, a renovated kitchen, or the view toward Lake Anne. In our experience a listing without a deep photo set and a floor plan shows up underdressed against the rest of the grid.
4. You are benchmarking against the wrong clock
Buyers in Reston read days on market as a signal, and the threshold is tighter than most sellers expect. The median condo went under contract in 21 days in July, which is the halfway point rather than the 26-day average quoted earlier. A unit still sitting at day 30 reads as a listing with a problem, whether or not it has one.
That perception becomes self-fulfilling. Showings taper, the agent inquiries change tone, and the offers that do arrive come in below where they would have in week one. The practical takeaway is that your pricing decision on day one carries far more weight than any correction you make in week five. Nothing recovers a fresh-listing week.
5. Your price sits just under a search filter
Buyers search in round numbers. Filters run $300,000 to $350,000, or $600,000 to $700,000. Price a townhouse at $698,000 and you vanish from every search that starts at $700,000.
In Reston this bites hardest just under $400,000 for condos, since 52 of the 108 active condos sit between $300,000 and $399,999 and that is where the searching is densest. Moving a list price up by $2,000 to land on a filter boundary can expose a listing to a materially larger pool of searchers. It sounds like a trick. It just acknowledges that the search box does the first round of filtering before any buyer sees your home.
6. You have not accounted for what buyers now need at the table
Concessions came back, and they came back regionally. Nationally, roughly two in five sellers gave concessions to buyers as of early 2025 according to Redfin tracking, close to the 2023 peak of 45 percent and well above the 22.5 percent low of the 2022 frenzy.
The reason is arithmetic rather than sentiment. In Northern Virginia, a buyer purchasing between $600,000 and $750,000 typically faces $10,000 to $18,000 in closing costs. Fairfax County property tax escrow alone can run $4,000 to $7,000 at settlement, depending on assessed value and timing. Add a year of homeowners insurance and per-diem interest and a buyer who budgeted carefully can still arrive short.
A buyer who is fully qualified on income and credit but stretched at closing is a real buyer you can win with a credit. If you have refused every concession request on principle, you may have talked yourself out of a sale. Our breakdown of seller concessions in Reston walks through which structures work in which price ranges, and where most loan programs cap them, generally three to six percent depending on loan type and down payment.
7. The condition gap is wider than the price gap
Buyers routinely discount for renovation work by more than it would cost to do, because they are pricing in the hassle as well as the materials. A kitchen that reads as dated in photos does not cost you the price of a kitchen. It costs you the showings you never get.
The condo bands punish this hardest, because the competing units are functionally identical and the only differentiators are finish level and price. Fresh paint, new flooring, and updated light fixtures will usually return more than the same money spent on a price reduction, and they will do it without signaling weakness. A price cut tells the market something is wrong. New flooring tells the market you are ready.
No amount of interest rate buydown makes a buyer overlook a home that needs $80,000 of deferred work or one priced well above where the market is valuing it.
8. Showing access is quietly killing you
Buyers and their agents will only work so hard. A listing with a two-hour weekday window, a required 24-hour notice, and a note about the dog gets skipped in favor of the one with a lockbox.
With 187 active listings in Reston and 3,025 across Northern Virginia, buyers have enough options that friction alone will remove you from a tour route. If you have restricted access for the past month, that is a variable you can change today at zero cost, and it is worth doing before you touch the price.
9. Something on title or in the disclosure packet is spooking people
Liens, unresolved permits, and open code violations turn up during a title search and stall deals late, when everyone is already invested.
Reston adds a local wrinkle. The Reston Association resale disclosure packet, and in condo communities the association resale certificate, can contain items that alarm a buyer who has not seen one before. RA also has 14 days by law from receipt of payment to deliver the packet, and it does not expedite, so this is a timing problem as much as a content one. A pending special assessment, a thin reserve fund, or an active covenant violation on your own property will all cool an offer. Pull your packet before you list rather than after you are under contract. Most issues are fixable, and every one of them is easier to explain on your schedule than during a contingency period.
10. Your agent is running a strategy built for a different segment
The approach that sells a $1.1 million detached home in nine days is not the approach that moves a $340,000 condo against 52 near-identical units in its own price band. The first is largely a pricing and exposure exercise. The second is a merchandising and differentiation problem.
If your agent’s plan for your condo is the same plan they use for detached homes, or if their comparative market analysis leaned on town-wide numbers, you have a mismatch. Ask directly what they have sold in your specific segment in the past six months, and what they did to make those listings stand out. A good answer will be specific. A vague one is its own answer.
What the fall market means for your timing
Contract activity in July gives a reasonable preview of what closes in September and October, since a contract signed in July generally settles 30 to 60 days later.
Detached homes in Reston posted 1.09 pending sales per active listing in July, up from 0.92 in June and 0.71 last July. Demand is strengthening.
Townhouses came in at 0.36, down from 0.80 last July and about 65 percent below the five-year July average of 1.01. Condos posted 0.21, running roughly 75 percent below the five-year July average of 0.83.
If you own a detached home in Reston, you are listing into strength. If you own a townhouse or condo, listing in September against a much larger field with meaningfully fewer buyers in contract is a different job than listing in May was. Not an impossible one, but it demands a sharper price and better preparation.
One piece of context keeps this in proportion. Even the loosest segment in Reston, condos at 3.09 months of supply across the whole segment, still sits below the five to six months that economists generally treat as a balanced market. This is a slower market than 2021. It is not a broken one.
The short version
If your home is not selling in Reston or Herndon in 2026, the reason is almost always one of three things. You priced against a town-wide number that describes a market you are not in. You underinvested in presentation while competing against dozens of nearly identical listings. Or you restricted access and never gave buyers a real chance to see it.
Everything else on this list is real, and any one of them can stall a listing. But those three account for most of what we see, and all three are fixable.
