Buying & selling in Fairfax County

Fairfax County at a glance

Fairfax County was created by the Virginia General Assembly on June 19, 1742 out of the northern part of Prince William County, and it is now the most populous county in Virginia and the most populous jurisdiction in the Washington metropolitan area (Source: Fairfax County Public Library). Two independent cities sit inside its footprint but are not part of it: the City of Fairfax, independent since 1961 and the county seat, and the City of Falls Church, independent since 1948. Each has its own government, tax rate and assessments, so an address and a jurisdiction are separate questions here. Adding to the confusion, the county's main administrative campus, the Fairfax County Government Center on Government Center Parkway, sits outside the City of Fairfax limits in unincorporated county land (Source: Wikipedia).

The housing divides mostly by era and by whether the ground was subdivided or master-planned. Annandale, Burke, Oakton and parts of Vienna hold detached houses — ramblers, split-levels and colonials — built largely between the 1950s and the 1970s on modest lots, many with no association at all. Reston, begun in 1964, and Kingstowne, begun in the 1980s, are master-planned and covenanted, with detached houses, townhouses and condos under association rules. Tysons and Reston Town Center hold the county's condo and apartment high-rises, most of them built alongside Silver Line construction. The incorporated towns of Vienna, Herndon and Clifton and the City of Fairfax's Old Town add older in-town stock on smaller lots.

Fairfax County, area by area

The county is a collection of separate markets with different housing stock, rules and commutes — McLean and Great Falls have their own guides (McLean, Great Falls), and these are the rest of the areas buyers ask about most:

• Vienna & Oakton — Vienna is an incorporated town with its own council-manager government inside the county, and the western terminus of Metro's Orange Line sits just outside it; the W&OD Trail runs through its downtown. Oakton next door is unincorporated, split by I-66 and Route 123, and has no distinct downtown of its own (Source: Wikipedia). Housing skews toward detached houses from the 1950s–70s, with in-town lots inside the town limits.
• Reston & Herndon — Reston is a master-planned community launched in 1964 and centered on Reston Town Center, with Silver Line stations at Wiehle-Reston East (2014) and Reston Town Center (2022); nearly all of it is covenanted land under Reston Association, whose Design Review Board reviews exterior changes (Source: Reston Association). Herndon is an incorporated town on the same corridor, the largest of the county's three towns, with its own Silver Line station opened in November 2022.
• Tysons — The county's central business district, grown from a 19th-century crossroads named for postmaster and landowner William Tyson into an edge city with headquarters including Capital One, Hilton Worldwide and Booz Allen Hamilton (Source: Wikipedia). Residential product here is condo and apartment high-rise built around four Silver Line stations, plus a Tysons Service District tax add-on of $0.050 per $100 on parcels inside it.
• City of Fairfax & Annandale — The City of Fairfax is an independent city, legally separate from the county, with its own tax rate and assessments; its Old Town went through a redevelopment beginning in 2005 that added retail, restaurant, office and residential space around historic buildings including the Old Town Hall, and George Mason University's main campus sits mostly in unincorporated county land just outside the city limits (Source: Wikipedia). Annandale, unincorporated and to the east, centers where Little River Turnpike, Columbia Pike and Backlick Road meet, with a business corridor of Korean-owned restaurants and shops built up from the 1990s onward.
• Springfield, Burke & Kingstowne — Springfield is built around the Mixing Bowl, the I-95/I-395/I-495 interchange rebuilt between 1999 and 2007 (Source: Wikipedia). Burke was built out from farmland starting in the 1960s and holds Burke Lake Park and two VRE Manassas Line stations. Kingstowne, begun in the 1980s by the Halle Companies, is planned and association-governed, mixing detached houses, townhomes, apartments and condos.
• Lorton & Mason Neck — Southern Fairfax County along the Occoquan River and the VRE Fredericksburg Line. Lorton housed a District of Columbia correctional facility from the early 1900s until it closed in November 2001; the site is now the Workhouse Arts Center (Source: Workhouse Arts Center). Gunston Hall, George Mason's home built between 1755 and 1759, sits on the Mason Neck peninsula nearby. Note that the town of Occoquan itself is across the river in Prince William County, not Fairfax.

Five things locals know

A few things that shape a purchase here and rarely make the listing sheet:

• Reston is named after its developer's initials — Robert E. Simon launched Reston on April 10, 1964, his 50th birthday, funded partly by proceeds from the Simon estate's sale of Carnegie Hall; the name is his initials, R.E.S., plus "-ton." It is described as the first 20th-century private community in the United States to build natural preservation into its plan, which is why so much of it is common land under covenant today (Source: Wikipedia).
• The county real estate tax rate has add-ons — Fairfax County's real estate tax rate is $1.12 per $100 of assessed value for Tax Year 2026, but individual parcels can carry special district rates on top of it — the Tysons Service District at $0.050 per $100, the Route 28 Improvement District at $0.105, the Commercial Transportation Tax District at $0.125 and a Stormwater Service District at $0.0325. The county reassesses annually at estimated fair market value as of January 1, and 2026 notices began mailing on February 17, 2026 (Source: Fairfax County).
• The W&OD Trail is a converted rail line — The Washington & Old Dominion Railroad ran its last train on August 27, 1968, and the Northern Virginia Regional Park Authority finished converting the right-of-way into today's paved 44.6-mile trail, Shirlington to Purcellville, by 1988. Inside the county it runs through Vienna, Dunn Loring and Herndon, which is why some back yards along it face a public path (Source: Wikipedia).
• Wolf Trap is the only national park for the performing arts — Catherine Filene Shouse donated roughly 60 acres of her Wolf Trap Farm in Vienna to the federal government, Congress accepted it in 1966, and she gave more than $2 million to build the Filene Center. It remains the only unit of the national park system created for the performing arts, and its outdoor season is run by the National Park Service with the Wolf Trap Foundation (Source: National Park Service).
• The Lorton arts campus was a workhouse — The Occoquan Workhouse, later the Lorton Reformatory, held Lucy Burns and 72 other members of the National Woman's Party in 1917 after they picketed the White House; the treatment they received is credited with shifting opinion toward the 19th Amendment. The buildings standing there now date to the 1920s and were built from brick made on site by inmates (Source: Workhouse Arts Center).

Getting around

Three Metro corridors reach the county and each one ends differently. The Orange Line terminates at Vienna, with Dunn Loring the stop before it. The Silver Line runs through Tysons and Reston — Wiehle-Reston East opened in July 2014, and Phase 2 opened on November 15, 2022, adding Reston Town Center, Herndon and Innovation Center on the way to Dulles Airport and Loudoun County (Source: FFXnow). The Blue and Yellow Lines terminate at Franconia–Springfield, open since 1997. VRE commuter rail adds two more options into Union Station on weekday rush hours only: the Manassas Line at Burke Centre, Rolling Road and Backlick Road, and the Fredericksburg Line at Lorton and Franconia-Springfield (Source: Fairfax County). Fairfax Connector, the largest local bus system in Northern Virginia at about 90 routes and roughly 33,000 daily riders, feeds the stations and Park & Ride lots (Source: Fairfax County).

By car, the tolling matters as much as the mileage. I-66 is dynamically tolled inside the Beltway for solo drivers eastbound from 5:30 to 9:30 a.m. and westbound from 3:00 to 7:00 p.m., and outside the Beltway there are 22.5 miles of dynamically tolled express lanes from I-495 to Gainesville, with HOV-3+ and transit free in both segments (Source: Wikipedia). The I-495 Express Lanes run from near Springfield to the Dulles Toll Road, with a northern extension to the American Legion Bridge completed in November 2025; the Dulles Toll Road is tolled for its full 16.15 miles and carries the Silver Line in its median. Washington Dulles International sits on the county's western edge with direct Silver Line access since November 2022, and Reagan National is reachable by Blue or Yellow Line from the Springfield end. On parking: detached houses and townhouses generally come with driveways or attached garages, while townhouse clusters and condo communities such as Reston and Kingstowne regulate assigned and guest parking through association rules rather than open street parking, which is worth reading before you commit to a townhouse.

The market & what to expect

Price differences across the county track jurisdiction, home type and era before anything else. A 1960s detached house in Annandale or Burke on a modest lot, a covenanted townhouse in Reston with a design-review obligation on the exterior, and a Tysons high-rise condo with a monthly fee and a service-district add-on are three different transactions with three different buyer pools. Land is largely built out, so newer product tends to be attached — townhouse and condo — while additions and teardown-rebuilds carry the older subdivisions. Whether a parcel sits in unincorporated county, in an incorporated town, or in an independent city changes the tax bill and who assesses the property.

Across Northern Virginia as a whole, the median sold price in July 2026 was $750,000 on 1,582 closed sales, with a median 21 days on market (Source: NVAR). That is a regional figure, not a Fairfax County one: NVAR's report combines Fairfax and Arlington counties, the cities of Alexandria, Fairfax and Falls Church, and the towns of Vienna, Herndon and Clifton, and it does not publish a Fairfax-County-only median in that release.

For buyers, the first work is narrowing: pick the rail line or VRE line you actually need, decide whether a covenanted community fits, and confirm the jurisdiction and utilities on the specific parcel before you fall for a house. For sellers, the job is identifying which buyer pool a home reaches — commuter, association, or high-rise — and pricing and preparing to that pool rather than to a countywide number. The buyer's guide and seller's guide lay out how Kelly runs each side, and the Arlington guide covers the county just to the northeast if you are weighing both.

Why work with Kelly in Fairfax County

Kelly Balmer is Vice President & Partner, Mollaan Babbington Group at Compass, licensed in DC, Maryland and Virginia, with $130M+ sold over 13+ years and a 5.0 Best-of-Zillow record across 130+ reviews. Her office is at 1313 14th Street NW in DC, which matters in Fairfax County, where a large share of buyers are comparing the county against DC, Arlington and Alexandria on tax rate, commute and home type before they settle on a jurisdiction at all.

In practice that means telling you early whether an address is unincorporated county, an incorporated town or an independent city, and what that does to the tax bill; reading association covenants and design-review rules before an offer rather than after; checking whether a property is on public water and sewer; and pulling comparables at the subdivision or building level instead of the county level. On the sell side she prices to the specific buyer pool a home reaches, documents prior work and any association approvals before they become a contract problem, and handles every transaction personally.
