Quick Answer: What Is a Herndon Home Worth in 2026?
Last updated October 23, 2026 by Nikki Lagouros, realtor with Berkshire Hathaway HomeServices PenFed Realty
A typical Herndon home is worth about $665,000 today, and the first thing that separates two similar Herndon homes is whether one sits inside the Town of Herndon. Redfin's September 2026 data for Herndon shows a $665,183 median over three months, up 11% from a year earlier, with a median of 36 days on market and a 99.6% sale-to-list ratio. Single-family homes ran about $750,000, townhomes about $566,000 and condos about $348,000. Outside the town, Herndon-addressed ZIP 20171, which includes Franklin Farm and Fox Mill Estates, had a $730,000 median.

What the numbers say: Redfin's Herndon figures cover a small number of sales, so the 11% gain partly reflects which homes sold. The Herndon median dipped to about $570,000 in early summer and rebounded by September. About 36% of homes sold above list, a sign that well-priced homes still draw competition.

What Drives Home Values in Herndon
Town of Herndon or a Herndon address
Town homes pay the Town's $0.27 per $100 on top of Fairfax County's $1.12, for a combined $1.39. On a $650,000 assessment that is $9,035 a year versus $7,280 outside the town. In exchange, Town residents get Town police, trash pickup and parks. See Town of Herndon vs. a Herndon address.
Historic downtown
The Herndon Historic District was listed on the National Register in 1991, and the Town's Historic District Overlay covers downtown. Buyers who want a walk to the W&OD Trail and Town Green pay for that location, and they also check the age of systems and any review needed for changes. See buying a historic home downtown.
Housing stock from the 1970s to the 1990s
Many county neighborhoods with Herndon addresses were built from the 1970s through the 1990s. Updated kitchens, baths, windows and HVAC separate those homes from originals more than square footage does.
Planned communities and HOAs
Franklin Farm and McNair Farms have mandatory HOAs with pools and amenities, while many older streets inside the town do not. Buyers weigh the fee against what it includes.
Two Silver Line stations
The Herndon and Innovation Center stations are in the Dulles Toll Road corridor. The Herndon station is about 1.8 miles on foot from downtown, so it is homes in the transit-oriented area near the station, and those with an easy drive to the garages, that gain the most.
Downtown redevelopment
The roughly five-acre downtown site at Elden and Center streets is tied up in the Town's legal dispute with Comstock. Its outcome will shape what buyers see on that block. Nikki tracks it in the Herndon development tracker.
Herndon Home Values by Area
Herndon's two ZIP codes divide roughly at the Dulles Toll Road. 20170 includes the Town of Herndon, while 20171 covers most of the Fairfax County communities with Herndon addresses.
| Area | Median, all homes | Single-family | Townhome | Condo | Median $/sq ft |
|---|---|---|---|---|---|
| 20170 Town of Herndon, downtown and nearby county streets north of the Toll Road | $743,000 | $789,000 | $483,000 | $348,000 | $311 |
| 20171 Franklin Farm, Fox Mill Estates, McNair Farms, Oak Hill and Floris | $730,000 | $915,000 | $653,000 | $380,000 | $307 |
Source: Redfin ZIP code housing market data, three-month medians ending September 2026, accessed October 23, 2026. "Few sales" means fewer than five sales of that type in the period. ZIP codes cross town and county lines, so a ZIP median is a starting point, not a price for your street.
Zestimate, Redfin Estimate or a CMA: Which Herndon Number Should You Trust?
Zillow says the Zestimate's nationwide median error is 1.77% for homes on the market and 7.20% for homes that are not listed. Redfin reports 1.91% and 7.49%. "Median" means half of estimates miss by more than that. On a $665,000 Herndon home, a 7.2% miss is about $47,880 in either direction.
Why online estimates miss in Herndon: they rarely separate Town and County homes, even though the Town tax adds more than $1,700 a year on a $650,000 assessment. They cannot see the condition of a 1900s downtown house or whether a 1980s colonial has been updated. Herndon's smaller sales volume also means the models lean on comparables from Reston, Sterling or Chantilly that may not match.
A comparative market analysis (CMA) from a realtor who has walked the house fills those gaps. An appraisal is a licensed appraiser's opinion, usually ordered by the buyer's lender.
