Walk the numbers before you walk the listing. In McLean's Knolewood subdivision, off Lewinsville Road, a buyer can currently pay $2,450,000 for Lot 2 or $2,500,000 for Lot 5. Neither has a foundation. Neither has a roof, a kitchen, or a single stud in place. Both are simply 0.83 acres of graded dirt with road access and utility stubs, waiting for someone to build.
That price for nothing but land sits above every published median for a finished McLean house right now. Zillow's own figure for the average McLean home value was $1,433,786 as of June 30, 2026. Redfin put the median sale price at $1.9 million over the three months ending May 2026. Movoto reported a median sold price of $2,199,000 for June 2026. The Knolewood lots land at or above all three. A buyer isn't paying a premium for dirt in McLean. In a real sense, the dirt is the product, and the house that eventually sits on it is closer to an accessory.
That single fact reframes almost every other number in this market. If you're comparing McLean to other Northern Virginia communities, the question isn't "what does the median buy." It's "which McLean transaction is the median even describing."
Three Portals, Three Numbers, One Small Market
Redfin counted 181 closed home sales in McLean in May 2026, the same total as May of the year before. Even with that much activity moving through the market, a specialized submarket like this can still swing on the mix of what closed in a given window, which is likely why Zillow, Redfin, and Movoto don't land on the same number. Zillow's $1.43 million reflects a modeled average across the full housing stock, including older colonials that haven't turned over in decades. Redfin's $1.9 million median reflects only homes that closed in the three months ending May 2026. Movoto's $2.199 million reflects June 2026 sales only, a month that may have carried a different mix of new construction and estate-lot closings.
The direction of travel is where it gets more interesting. Redfin's own data shows homes selling in 19 days on average in the three months ending May 2026, down from 26 days the year before, which reads like a market accelerating. Movoto's June 2026 figures show the opposite: an average of 47 days on market, up from 45 the year before. Both can be true at the same time, because they're not describing the same slice of inventory. One is capturing the fast lane, land-value teardown candidates and near turnkey homes that move quickly. The other may be catching more of the slower-moving, dated inventory sitting at prices that no longer match what the land underneath is actually worth.
This isn't a new pattern. FFXnow, the local outlet covering Fairfax County development, reported that McLean's median sale price surpassed $2 million in October 2025, even as the number of homes sold declined year over year and days on market lengthened. Rising price paired with falling volume and slower sales doesn't mean everything got more expensive. It usually means the transactions that did close skewed toward the high end, land included, while everything else waited.
The Old Colonial Isn't Being Discounted. It's Being Priced as Land.
McLean's older neighborhoods, Langley Forest, Franklin Park, Salona Village, and West McLean among them, are largely built out on half-acre and quarter-acre lots dating to the 1960s through the 1980s. Much of the community outside Tysons and the McLean Community Business Center is already at capacity, which means there's almost no vacant land left to develop. Knolewood is the exception precisely because it sat undeveloped for more than 60 years under one family's ownership before the parcel changed hands in October 2024 for $27 million.
Everywhere else, new supply only happens by replacing what's already standing. That single constraint is what pushes land value to the front of the pricing conversation on an outdated colonial that would, in most other Northern Virginia markets, simply sell at a discount for its condition.
A dated split-level on a good lot in one of these neighborhoods isn't necessarily underpriced or overpriced relative to its finishes. It's priced closer to what the ground beneath it is worth, with the structure itself functioning as a placeholder the next owner may or may not keep.
"What makes Knolewood extraordinary is the shared commitment to excellence," TTR Sotheby's International Realty senior vice president Mona Banes said of the subdivision's builder team, according to FFXnow's coverage of the project.
That commitment applies to Knolewood's three approved builders, Artisan Builders, Galileo Signature, and Winthrop Builders, who are working from a blank 25-acre slate. Most McLean buyers don't get a blank slate. They get someone else's 1975 rambler and a decision to make about what the lot underneath it is actually worth.
Two Ways to Spend Roughly $2 Million in McLean Right Now
| Path | What you're actually buying | Typical timeline | What you own at the end |
|---|---|---|---|
| Knolewood raw lot ($2.4M-$2.5M) | 0.82 to 1.2 acres of graded, road-served land | 18 to 30 months from lot purchase to occupancy, per local custom builder timelines | A custom home you designed, built by one of three HOA-approved builders |
| Teardown-rebuild elsewhere in McLean | An older home priced near land value, plus demolition and new construction | Similar 18 to 30 month window once design, county review, and construction phases are added | A custom home on an established street, no HOA builder restriction |
| Ritz-Carlton Residences, McLean, Tysons (from $1M) | A branded, fully finished condominium up to 4,500 square feet, no private lot attached | Construction begins 2026, occupancy targeted late 2028 | A finished unit with hotel-style service, zero site control |
The Ritz-Carlton project, developed by Renaissance Centro at 7925 Westpark Drive adjacent to the Ritz-Carlton Tysons Corner hotel, is worth sitting with for a moment because it's the clean opposite case. Buyers there are paying for architecture by FXCollaborative, interiors by MAWD, and more than 15,000 square feet of shared amenities. They own none of the ground it sits on. It's the same McLean ZIP code, the same general price range as a raw Knolewood lot, and a completely different economic bet.
Full custom construction elsewhere in McLean carries its own arithmetic. A realistic 2026 project, roughly 5,200 square feet above grade with a finished basement, typically lands between $3.8 million and $4.5 million once land, demolition, design, permitting, construction, and landscaping are counted. Construction alone runs $350 to $550 per square foot before land is added. Land acquisition in McLean frequently exceeds the entire finished cost of a comparable new home in less land-constrained parts of Virginia, which is the same fact Knolewood's individual lot pricing illustrates directly.
Where the Friction Actually Shows Up
None of this is a reason to avoid McLean. It's a reason to slow down before assuming a "needs work" listing is a bargain. Fairfax County treats a valid lot and a buildable lot as two different things, and confirming which one you're looking at takes real diligence before demolition plans go anywhere:
- Confirm the lot satisfies minimum yard, floodplain, and legal road access requirements, since a lot can be legally recognized and still fail to meet current buildability rules.
- Check for Resource Protection Area conditions along any nearby stream or wetland. Land disturbance beyond 2,500 square feet inside these zones generally requires a separate county permit before any grading begins.
- Expect two distinct permits rather than one: a residential demolition permit for the existing structure, and a separate new-building permit for construction, each touching zoning, wastewater, and building plan review.
Renovation carries its own version of this friction. Aging plumbing, electrical systems, and foundations can turn what looks like a straightforward update into a project that costs nearly as much as starting over, without delivering the layout flexibility or efficiency a full rebuild provides. That's the calculation worth running before committing to either path, and it's the same property-potential-versus-price analysis that applies whether you're weighing a McLean estate lot or a smaller renovation candidate anywhere else in the region. It's also where financing tools like FHA 203(k) and Conventional HomeStyle loans earn their place in the conversation for buyers working in a lower price band, since they fold renovation costs into a single mortgage rather than forcing a separate construction loan.
A Few Straight Answers
Does a lower asking price on an older McLean home mean it's a good deal? Not automatically. If the price already tracks close to land value in a neighborhood like Langley Forest or Franklin Park, the discount may reflect the cost of eventually removing the structure rather than genuine savings on a livable home.
Why do Zillow, Redfin, and Movoto show different numbers for the same neighborhood? Each measures a different slice of the market. Modeled typical values, closed-sale medians over a rolling window, and single-month medians will diverge in a market this small, especially when only a few dozen homes close in any given month.
How long does a full teardown rebuild actually take in McLean? Local custom builder timelines put the full process, from lot purchase through occupancy, at roughly 18 to 30 months, with county plan review typically consuming 2 to 4 months of that window.
Can I use any builder I want on a Knolewood lot? No. Knolewood requires buyers to work with one of three HOA-approved builders, Artisan Builders, Galileo Signature, or Winthrop Builders, which is a different arrangement than buying an existing lot elsewhere in McLean with no builder restriction attached.
Whether you're weighing a raw lot, a dated colonial, or a fully finished condominium, the question underneath all of it is the same: are you pricing the structure, or are you pricing the ground it sits on. That's a harder read than a portal median gives you, and it's worth working through before an offer goes in. Brandon Foy and the Sproost Properties team spend as much time on that property-potential analysis as they do on the paperwork that follows it. Let's Get You Started.
