Pull up McLean's housing market on three browser tabs in the same afternoon and you will get three different answers to what looks like a simple question. One site says the typical home is worth $1.43 million. Another says the median sale price is $1.9 million. A third shows active listings sitting at a median of $2.2 million. Same zip codes. Same season. Three numbers that do not reconcile.
If you are comparing McLean to Vienna, Oakton, or a neighborhood two counties over, this matters more than it should. A buyer who anchors on the wrong number will misjudge what their budget actually buys, or worse, will misprice a home they are trying to sell. The gap is not a glitch in anyone's data. It is a symptom of what McLean actually is: two very different housing products sold under one mailing address.
The Same Zip Code, Three Numbers
Here is what each source was showing as of mid-2026, and what each one is actually measuring.
| Source | Figure | What it measures | As of |
|---|---|---|---|
| Zillow (ZHVI) | ~$1.43 million average, up 4.4% year over year | A modeled "typical value" across all homes, not just those that sold | June 30, 2026 |
| Redfin | $1.9 million median sale price, up 9.7% year over year, at $466 per square foot | Closed sales over the trailing three months | Three months ending May 2026 |
| Movoto | $2.199 million median list price, $490 per square foot, 47 days on market | Active listings currently for sale | June 2026 |
None of these is wrong. Each one is sampling a different slice of the same market, and in McLean, those slices look nothing alike. A home value index that averages in every property, including modest ranchers that haven't sold in years, will always sit lower than a median built from actual closed transactions, which will in turn sit lower than a snapshot of what's currently listed for sale, since sellers of finished luxury rebuilds tend to list at a premium relative to what closes.
Redfin's own market commentary makes the point directly: in a market where monthly sales counts are small, a handful of high-value closings can swing the median considerably. McLean typically posts under 200 closed sales a month. That is a small enough sample that one busy week of $3 million-plus closings, or one quiet week without them, changes the headline number.
Two Products Under One Roof
The real explanation sits in the housing stock itself. McLean's inventory splits into two categories that behave like separate markets, even though they share the same school boundaries and the same zip code.
The first category is the aging home on a valuable lot. Much of McLean was built out in the 1960s and 1970s, and that generation of colonials, ramblers, and split-levels increasingly runs into the same wall: low ceilings, compartmentalized floor plans, and mechanical systems that were never designed for a modern renovation. Once the cost of bringing one of these homes up to current standards approaches roughly 70 percent of what it would cost to replace the structure outright, the math tips toward tearing it down rather than fixing it up. Renovation still wins when the scope stays closer to 30 percent of the home's current market value and the bones (framing, masonry, layout) are sound. Between those two thresholds is where most of the disagreement happens.
The second category is the new-construction or freshly rebuilt estate. These are the homes pulling Movoto's active-listing median toward $2.2 million and beyond, some priced from roughly $2.4 million to over $4 million for newly built homes in the 5,000 to 8,600 square foot range.
What ties the two together is land. Premium McLean lots, independent of whatever house sits on them, are reported to command anywhere from $900,000 to $2 million depending on size, proximity to Washington, school pyramid, and the specific neighborhood. That is the number a serious buyer needs before they ever ask what the house on the lot is worth.
Where the Split Shows Up Block by Block
The bifurcation is not evenly spread across McLean. Certain neighborhoods carry it more visibly than others.
- Langley Forest, Franklin Park, Salona Village, and West McLean are where most of the active rebuild activity concentrates. These are established neighborhoods with half-acre and quarter-acre lots still holding a meaningful share of 1960s through 1980s homes, which is exactly the profile that tends to cross the renovation-versus-rebuild threshold.
- Broyhill Estates adds a redevelopment layer where older homes are increasingly evaluated less as livable residences and more as land plays. A builder sees a teardown opportunity where a buyer might see a dated house, and that difference in perspective changes the number a seller should expect.
- Lewinsville trades on a different value proposition entirely: proximity to retail and a tighter link to the urbanizing edge of Tysons. Buyers here are increasingly willing to trade lot size for walkability, which pulls this pocket's pricing logic away from the acreage-driven estates further west.
If you're comparing neighborhoods rather than individual homes, knowing which of these categories a listing falls into tells you more than any county-wide average will.
What to Actually Compare
Once you understand that McLean's median is really an average of two different products, the practical move is straightforward.
- Compare price per square foot only within the same product type. A rebuild's cost per foot and a 1968 rambler's cost per foot are not measuring the same thing, even on the same street.
- Ask directly whether a listing is being marketed as a livable home or as a lot with redevelopment potential. Agents increasingly position teardown-candidate properties both ways to widen the buyer pool, and the asking price should reflect which pitch is doing the heavy lifting.
- Use a tight, recent window of closed sales in the exact subdivision and school pyramid rather than a citywide figure. McLean's small monthly sales count means a broader average absorbs noise from whichever segment happened to transact that month.
The Permit Path If You're Buying the Lot
If the math points you toward a teardown rather than a move-in-ready home, the value proposition depends on what Fairfax County will actually let you build, and that is where buyers get surprised.
A lot being legally valid is not the same as a lot being buildable. Fairfax County recognizes lots created before March 1, 1941 as automatically valid, with some later lots qualifying based on county mapping and structure history. Even a valid lot still has to clear setback requirements, floodplain restrictions, Resource Protection Area rules tied to the Chesapeake Bay Preservation Act, erosion and stormwater standards, and confirmation of legal road access before a building permit is issued. Any project disturbing 2,500 square feet of land or more triggers an additional infill lot grading plan and a closer look at stormwater management. On the demolition side, the county requires written confirmation from every utility company serving the property before it will issue a demolition permit at all.
There is also a live gap worth knowing about before you commit to a design. Fairfax County's current zoning ordinance limits new residential construction primarily through height and setback rules, without an explicit standard tying a structure's overall bulk to the size of its lot. That gap drew attention this year after a zoning dispute pushed the Board of Supervisors to direct county staff toward reviewing residential height and massing standards, with recommendations expected by the end of 2026. Anyone buying a teardown lot today is building under the current rules, but should not assume those rules will look identical a year from now.
None of this is theoretical demand. The clearest evidence that new supply keeps arriving at the top of McLean's market is the Ritz-Carlton Residences, which broke ground this year in McLean Tysons. It is the Ritz-Carlton brand's first stand-alone Virginia property, a 102-unit building targeting delivery in late 2028. That kind of investment at the luxury end is part of why the active-listing median keeps drifting upward relative to the closed-sale median for older stock.
A Few Questions Worth Asking Before You Compare Numbers
Which number should I actually trust when comparing McLean to another neighborhood? None of them alone. Match the figure to the product you're actually shopping for. If you're looking at a rebuilt estate, Movoto's active-listing median is closer to your real comparison set. If you're evaluating a 1970s rambler, a tight, recent closed-sale comp in that exact subdivision tells you more than any citywide average.
If a home falls under the 70 percent renovation threshold, does that mean it's not a teardown candidate? Not necessarily. Land economics can override the renovation math entirely. A lot in a scarce, high-demand pocket can still be worth more torn down than preserved, regardless of how reasonable the renovation cost looks on paper.
Does this three-number problem show up everywhere, or is it specific to McLean? Any established, largely built-out area with a wide gap between its oldest and newest housing stock will show some version of this. McLean's spread is unusually wide because it holds ultra-luxury estates, classic 1960s and 1970s homes, and active rebuild lots within the same zip codes and the same small monthly sales sample.
If you're trying to figure out where your own McLean property or target neighborhood actually sits between these numbers, that's a conversation worth having before you list or make an offer, not after.
