The honest answer is that the data behind this report cannot say, because no North versus South McLean price split exists in the source material. The study sample covers 60 older homes across ZIP code 22101 as a single market, with 20 acquired by builders and an average older home price of 42.6 percent of new build value (Frontier Capitals, 2026), and the market data for the ZIP, including a median sale price near 1,800,000 dollars, is reported for 22101 as a whole (Redfin, 2026). Anyone quoting a precise premium for one half of McLean over the other is offering a number this evidence does not contain.
What the evidence does support is a method for answering the question on any given street, and a clear account of the factors that would produce a gap if one exists. Value inside 22101 is documented to move with lot size and shape, school pyramid, proximity to downtown McLean and the CIA corridor, and the condition of the house itself. Those factors are not distributed by compass point in any data available here. They are distributed street by street, which is why two homes a mile apart in the same half of McLean can differ by more than the supposed halves ever could.
Key Findings
- No North versus South McLean price split exists in the source data for this series, so no premium percentage for either half can be stated honestly.
- The documented sample treats 22101 as one market: 60 older homes, 20 builder acquisitions, a 33.3 percent builder demand rate and a 42.6 percent average price ratio to new builds (Frontier Capitals, 2026).
- ZIP wide market figures are the available baseline, with a median sale price near 1,800,000 dollars and new construction selling from 2,500,000 to 4,500,000 dollars (Redfin, 2026).
- The value drivers with evidence behind them are lot quality, school pyramid, proximity to downtown McLean and the CIA corridor, and condition, none of which follow a north south boundary in the data.
- A fair test of the question requires recorded deeds compared lot for lot and pyramid for pyramid, a comparison any owner can run from county records (Fairfax County Circuit Court Clerk, 2026).
What would count as evidence for a gap between the two halves?
Recorded sales, sorted by a defined boundary, with everything else held as constant as the market allows. The deed record is the starting point, because it shows what buyers actually paid, in which entity names, on which parcels (Fairfax County Circuit Court Clerk, 2026). A credible study would draw a line, state where it runs, assign every recorded 22101 sale to a side, and then compare like with like: similar lot sizes, similar house ages, similar school pyramids, similar condition. Without those controls, a gap in averages may only prove that one half has larger lots or newer houses.
Assessment records would form the second evidence layer. Fairfax County assessments exist parcel by parcel across the whole ZIP (Fairfax County Department of Tax Administration, 2026), so an assessment based comparison is at least constructible, unlike a claim built on asking prices. Even then, assessments follow recorded sales with a lag and smooth over the very street level variation the question asks about. They can support a method. They cannot substitute for the missing study.
The third layer is valuation discipline. Federal guidance on appraisal data and reconsideration of value exists precisely because location adjustments in appraisals must be evidenced rather than asserted (Federal Housing Finance Agency, 2025). A north south premium asserted without paired sales would fail that standard in a lender file, and it should fail it in a seller pricing decision too. Owners reading the overview of which McLean neighbourhoods carry the highest property values will notice the same pattern: the documented differences attach to named areas and school pyramids, not to compass halves.
It is also worth asking who benefits from an unexamined premium claim. A seller in the supposedly stronger half may overprice on the strength of it and fund months of holding costs. A buyer in the supposedly weaker half may be talked out of a well priced home on a strong lot. In both cases the claim, not the market, did the damage.
Why does the available McLean data not divide the ZIP that way?
Because the research was designed around a different question. The sample compiled for this series selected 60 pre 1981 homes in 22101 to measure builder demand for older stock, and it reports the ZIP as a single local submarket inside the Capital Beltway (Frontier Capitals, 2026). Its geography is the parcel, the street and the school pyramid. A north south variable was never collected, and a variable never collected cannot be recovered afterwards by rearranging the published averages.
The market data services used in this series report at the same ZIP level. Sold prices, new construction ranges and days on market for McLean are published for 22101 as a whole (Redfin, 2026; Zillow, 2026), with average days on market of 34 to 69 and a median near 1,800,000 dollars. County context is broader still, describing Fairfax County as a single jurisdiction (U.S. Census Bureau, 2025). At every level of the evidence stack, the smallest unit with a published figure is the ZIP, not a half of it.
There is also no agreed boundary to measure against. North and South McLean are conversational labels, not assessment districts, zoning categories or school pyramids. The named areas that do appear in McLean source material are Chesterbrook, Langley and the Chain Bridge area, each defined by roads, schools and history rather than by a line across the ZIP. Zoning and subdivision records, which are the county documents that would have to recognise a boundary for it to carry legal weight in valuation, contain no such division (Fairfax County Department of Planning and Development, 2026).
National housing stock data adds a final caution. Survey evidence on the age and characteristics of owner occupied housing (U.S. Census Bureau, 2024) shows how strongly value tracks the era and type of a house. McLean older stock is heavily 1950s and 1960s ramblers and split levels, and if one half of the ZIP simply holds more of the larger, later or better kept examples, a raw average gap would describe housing mix, not geography. That is exactly the kind of false precision the method in this report is designed to avoid.
Which factors would a fair comparison have to hold constant?
Lot quality first, because it is the strongest documented driver for the older stock. A flat, wide, quarter acre plus lot that fits a modern floor plan is worth materially more than a narrow or steeply sloped one, and the sample lots range from an atypical 799 square foot parcel at the edge of the dataset to the typical quarter acre and above (Frontier Capitals, 2026). If one half of McLean held systematically wider and flatter lots, its older homes would record higher land led prices for reasons having nothing to do with its name.
School pyramid second. Parcels zoned for the most sought after high schools carry premiums visible in new build comparables but rarely in older home listings, and families relocating to the Langley and McLean pyramids pay top prices for finished homes. A north south comparison that ignored pyramid boundaries would bury one of the few price effects with consistent evidence behind it. The Langley side of McLean, around the Langley pyramid and the CIA corridor, is discussed on its own documented terms in the report on whether luxury homes in Langley still sell at premium prices.
Proximity third. Position near downtown McLean, the CIA corridor and Metro access points registers in land bids, and new construction near Langley, the Beltway corridor and McLean village centres commands premium prices (Redfin, 2026). These are point locations and corridors, not halves. A home in the southern part of the ZIP beside a village centre may sit on stronger land economics than a home in the northern part at the end of a long residential street, and the documents behind this report would price them that way.
Condition last, because it can swamp geography entirely. A fully updated home and an original 1962 rambler on identical lots are different products, and permit records for the ZIP show a steady pattern of older homes being replaced by 6,000 plus square foot new construction (Fairfax County Land Development Services, 2026). Any comparison that mixed renovated and original homes across an imaginary line would mostly measure where renovations happened to cluster. The disciplined version of the question is therefore not north against south. It is this lot, this pyramid, this condition, against the recorded evidence for the same combination, wherever in McLean that evidence sits. Owners can see how that logic prices the ZIP as a whole in the report on what older homes are worth in the 22101 ZIP code.
What do the figures that do exist say about value inside 22101?
They describe a high value market with a wide internal range. The median sale price near 1,800,000 dollars (Redfin, 2026) coexists with new construction from 2,500,000 to 4,500,000 dollars depending on street, lot size and school pyramid (Redfin, 2026; Zillow, 2026), and with older homes averaging 42.6 percent of new build prices on comparable lots. A range that wide inside one ZIP is itself evidence that micro location and product type dominate any coarse geographic split. If a simple compass line explained McLean value, the ZIP wide figures would not need so many qualifiers.
Builder behaviour tells the same story. Builders acquired 20 of the 60 sampled older homes, a 33.3 percent demand rate (Frontier Capitals, 2026), and they did not buy a compass direction. They bought individual lots that fit a modern floor plan, in school pyramids where finished homes command premiums, at prices the residual arithmetic supported. Deed by deed, the purchases are recorded across the county land records (Fairfax County Circuit Court Clerk, 2026), and any owner can map the recent ones near their own street before entertaining a theory about halves.
For a seller, the practical translation is that the market will price the parcel in front of it. An appraisal that leans on a supposed half premium without paired sales invites a reconsideration challenge under the standards that govern lender valuations (Federal Housing Finance Agency, 2025). A pricing case built on the documented drivers, by contrast, survives contact with appraisers, buyers and builders alike, because each element can be pointed to in a record: the lot in the assessment file (Fairfax County Department of Tax Administration, 2026), the pyramid in the county planning records (Fairfax County Department of Planning and Development, 2026), the comparables in the deed archive.
How should an owner price and sell without a north south figure to lean on?
Price from the micro evidence, in this order: recorded sales on the same street, then sales of similar lots in the same school pyramid, then the ZIP wide baseline of a median near 1,800,000 dollars and the 42.6 percent older home ratio (Frontier Capitals, 2026; Redfin, 2026). If those layers point in different directions, trust the nearest layer. A seller in either half of McLean who follows that order will land closer to the market than a seller anywhere who prices from a slogan about halves.
The selling route can then be chosen on documented costs rather than geography. Frontier Capitals sources off market deals to builders and acts as a wholesaler, never as the builder, and its terms address the costs every McLean seller faces regardless of which half they live in. Privacy is complete, with zero showings and zero open houses. Timing is flexible, closing in 7 to 21 days or months out with a leaseback, against the 60 to 120 plus days a listed older home commonly takes. No commission is charged, against the typical 5 to 6 percent worth 80,000 to 96,000 dollars on a 1,600,000 dollar sale, and no seller closing costs, against the typical 1 to 2 percent, with the two together commonly reaching 6 to 8 percent of price. The sale is as is, with no inspections or repairs and no 10,000 to 30,000 dollar repair credits, against listed inspection concessions that commonly run 15,000 to 40,000 dollars on older homes.
None of those figures changes across an imaginary line through the ZIP, which is rather the point of this report. The costs, the timelines and the buyer arithmetic are documented for McLean as a whole, and they are the ground on which a real decision can be made today.

Methodology and limitations
The central limitation must be stated plainly: the source material for this series contains no North versus South McLean price split, no boundary definition and no sub ZIP dataset from which one could be calculated. The sample behind the figures is 60 older homes across 22101, selected for pre 1981 construction, reported as one market (Frontier Capitals, 2026), and market statistics are published at ZIP level by the cited services (Redfin, 2026; Zillow, 2026). This post therefore answers by method, describing the comparison that would settle the question and the factors the documented evidence says such a comparison must control.
No new dataset was created for this report, no property was appraised or inspected, and no title search was performed. The method described relies on public records that exist independently of this series: deed records (Fairfax County Circuit Court Clerk, 2026), assessment records (Fairfax County Department of Tax Administration, 2026), zoning and subdivision records (Fairfax County Department of Planning and Development, 2026) and permit records (Fairfax County Land Development Services, 2026). A future study built from those records could answer the headline question directly. Until one exists, any precise north south premium quoted for McLean should be treated as unsupported.
Conclusion
On the evidence available, homes in North McLean cannot be shown to be worth more than homes in South McLean, or the reverse, because the data was never collected in those terms. What can be shown is substantial: a ZIP wide median near 1,800,000 dollars, new construction from 2,500,000 to 4,500,000 dollars, a builder demand rate of 33.3 percent for older homes, and a consistent set of value drivers in lot quality, school pyramid, proximity and condition (Frontier Capitals, 2026; Redfin, 2026). Those drivers operate street by street, and they are sufficient to price any individual McLean home without borrowing a premium from a compass point.
If the line between north and south cannot be found in any county record, why should it appear in the price of your home?
Frequently Asked Questions
Is there any published figure for a North McLean premium?
Not in the source material for this series. The study sample reports 22101 as a single market of 60 older homes (Frontier Capitals, 2026), and market services publish the ZIP median near 1,800,000 dollars for McLean as a whole (Redfin, 2026). No halves, no boundary and no split are documented.
How could the question be answered properly?
By assigning recorded sales from the deed archive (Fairfax County Circuit Court Clerk, 2026) to a stated boundary, then comparing matched lots, pyramids and conditions on each side. Assessment records (Fairfax County Department of Tax Administration, 2026) could support the work, but the study has not been published in the sources available here.
Which matters more to McLean value, location within the ZIP or the lot itself?
On the documented evidence, the lot and the school pyramid carry the measurable effects: a flat, wide, quarter acre plus lot is worth materially more than a narrow or sloped one, and pyramid premiums appear clearly in new build comparables. A compass label has no documented effect at all.
Does the Langley area prove that one part of McLean is worth more?
It proves that a named area around a sought after school pyramid and the CIA corridor commands premiums, which is a different claim from a north south split. Langley is defined by its pyramid and corridor, not by a line across the ZIP, and its pricing is examined separately in this series.
How should a seller in either half set a price today?
From recorded sales on the same street and in the same pyramid first, then against the ZIP baseline: median near 1,800,000 dollars, older homes at 42.6 percent of new build prices on comparable lots (Frontier Capitals, 2026; Zillow, 2026). That order uses evidence at the scale at which it actually exists.
