Two McLean listings can carry nearly the same price tag and mean completely different things. One is a finished four-bedroom colonial with a renovated kitchen and a buyer who can move in next month. The other is a 1950s rambler on a wooded third of an acre near Franklin Park, priced almost identically, where the real transaction is the dirt underneath the house. A builder already has the teardown penciled out. The house itself is a rounding error.
That gap is the whole story of why McLean's "median home price" refuses to sit still. If you have spent any time comparing sources before deciding whether McLean fits your search, you have probably noticed the numbers do not agree with each other, sometimes by hundreds of thousands of dollars. That disagreement is not noise. It is the market telling you something true, and worth understanding before you write an offer.
The number that keeps moving because the product keeps changing
As of July 31, 2026, one widely used home value index put McLean's typical home value at $1,472,788, up 1.4 percent over the prior year. A separate source tracking actual closed sales over the three months ending May 2026 reported a median of $1.9 million, up 9.7 percent year over year, with homes going under contract in about 19 days. By June 2026, the average sale price in that same dataset had climbed to roughly $2.08 million.
Go back to February 2026 and a third source pegged the median closed price at $2,101,362, more than $600,000 above the typical value estimate from the same general window.
None of these sources are wrong. They are measuring different things. A home value index averages the estimated worth of every home in McLean, whether it sold that month or not. A median closed price only counts what actually changed hands, and what changes hands shifts month to month depending on the mix of properties that happen to close. When a run of ultra-premium estate sales lands in the same month as a batch of attached homes and older colonials, the median swings hard in one direction or the other. McLean's housing stock is not one product. It is several, sitting side by side on the same MLS pages, and the reported median is only ever a snapshot of whichever mix happened to sell.
The ZIP code split tells you where the mix comes from
Nowhere is that mix more visible than at the ZIP code level. Data from earlier in 2026 showed McLean's 22101 ZIP code with a typical home value around $1,696,151, while 22102, the section that runs closer to Tysons, came in around $841,470. That is roughly a two-to-one spread inside a single community name.
| ZIP Code | Typical Home Value (early 2026) | General Character |
|---|---|---|
| 22101 | ~$1,696,151 | Established single-family neighborhoods, larger lots, closer to downtown McLean |
| 22102 | ~$841,470 | Closer to Tysons, more condominiums and attached product in the mix |
The lower average in 22102 is not a sign of a weaker submarket. It reflects a different housing type entirely, with more condominiums and attached homes pulling the number down. Buyers comparing McLean to other DMV neighborhoods on the strength of a single headline figure are often comparing an average across both ZIP codes to a competing area's more uniform housing stock, which is not a fair comparison at all.
Where the land is worth more than the house
The bifurcation goes deeper than ZIP codes. Inside McLean's older, tree-lined neighborhoods, particularly Franklin Park and Franklin Forest, a specific pattern has taken hold: homes built in the 1940s and 1950s are being replaced with much larger new construction, because the land underneath them is now worth more than the structure sitting on it.
The economics are stark when you see them side by side. A recent teardown-bound sale in the Franklin area closed around $1.08 million, while a new build nearby on comparable land reached nearly $5 million. That is not appreciation. That is two entirely different transactions wearing the same neighborhood name. The 1950s rambler was never competing on kitchen finishes or square footage. It was a land purchase with a house attached, and the price reflected the lot, the tree canopy, and the buildable envelope, not the four walls.
This matters for anyone using McLean's median price to size up a purchase. If a chunk of a given month's closed sales are land purchases disguised as house sales, the median tells you almost nothing about what a move-in-ready home actually costs that month. You need to know which product you are looking at before the price means anything.
The rule that decides whether the land actually pencils
Here is the friction that catches buyers off guard once they get serious about an older McLean lot: not every home with land-value upside is actually a viable teardown, and the difference often comes down to rules that never show up in a listing description.
Fairfax County treats Resource Protection Areas, the buffer zones along streams that fall under the Chesapeake Bay Preservation Ordinance, as a hard constraint on redevelopment. Generally, no land disturbance, development, or vegetation removal is allowed within an RPA without prior county approval, and any project disturbing more than 2,500 square feet triggers a formal review. Add tree conservation requirements, floodplain overlaps, and in some cases well or septic approvals, and a lot that looks generous on the plat can end up far more constrained once real-world rules are applied.
A lot can be legally valid and still not be buildable in the way a buyer assumes. Fairfax County's own guidance draws that line explicitly, and it is one of the most consequential distinctions in any McLean teardown deal.
There is a useful historical wrinkle here too. Fairfax County treats lots platted before March 1, 1941 as automatically valid under current subdivision rules. Franklin Park, platted around the turn of the twentieth century, likely has a meaningful share of lots that clear that bar on age alone. But automatic validity is not the same as automatic buildability. A pre-1941 lot can still run into an RPA along its rear property line, a floodplain notation, or a tree conservation area that shrinks the usable building envelope well below what the acreage on paper suggests.
For a buyer evaluating an older McLean home purely on land-value math, that is the step worth taking before an offer, not after one. For a seller sitting on a similar property, it is the difference between marketing a house and marketing a site, and the two require very different pricing conversations.
A few questions worth asking before you compare McLean to anywhere else
Does a lower ZIP code average mean 22102 is a worse place to buy? No. It means the housing product is different, weighted more toward condominiums and attached homes near Tysons rather than detached houses on larger lots. Comparing it directly to 22101 without adjusting for housing type will mislead you either way.
If I'm looking at an older home with obvious teardown potential, how do I know the numbers actually work? Start with the site, not the sale price. Confirm the zoning district, pull the plat or house location survey, and check whether any part of the lot falls inside a mapped Resource Protection Area before assuming the land value carries the deal.
Why does the same month sometimes get reported with two different medians? Because different sources measure different things. A closed-sales median only counts homes that actually sold that month, while a home value index estimates every property in the area regardless of whether it changed hands. Both are accurate. Neither is the whole picture on its own.
Where this leaves you
McLean's price data will keep looking inconsistent from the outside, and that inconsistency is actually useful information if you read it correctly. The real question is never what the median says this month. It is which submarket, which ZIP code, and which category of property you are actually comparing against the rest of the DMV.
If you are weighing McLean against another close-in neighborhood and want to know what a specific budget actually buys once the ZIP code and property type are accounted for, that is exactly the kind of comparison worth working through with someone who follows this market closely. Ricardo Vasquez has spent 25 years across DC, Maryland, and Northern Virginia pricing exactly this kind of nuance into a decision. Let's Connect.
