On the McLean side, the figure can be grounded: when new construction sells near 3,200,000 dollars, the simplified residual in the research file leaves roughly 1,250,000 dollars to 1,450,000 dollars for the land, after about 1,300,000 dollars of hard and soft building costs and a builder margin near 20 percent, and before site preparation of 30,000 dollars to 50,000 dollars (Frontier Capitals, 2026). New homes on standard McLean lots have closed across a wider 2,500,000 dollars to 4,500,000 dollars band, which pushes the implied land band lower or higher street by street (Redfin, 2026; Zillow, 2026).
On the Washington, DC side, this report must be candid about a limit: no residential lot dataset for Washington, DC exists in the neighbourhood source material behind this series, so no verified DC lot average can be quoted here. What can be compared honestly is method: how a lot price is built in McLean, which inputs would have to be gathered for Washington, DC before any comparison deserves trust, and why borrowing a DC figure from general impression would mislead a McLean seller.
Key Findings
- The McLean residual illustration leaves 1,250,000 dollars to 1,450,000 dollars for land beneath a 3,200,000 dollar finished sale, before 30,000 dollars to 50,000 dollars of site preparation (Frontier Capitals, 2026).
- Sampled older McLean homes averaged 42.6 percent of new build prices on comparable lots, a second route to reading land led value in 22101 (Frontier Capitals, 2026).
- Finished McLean construction on standard lots has sold from 2,500,000 dollars to 4,500,000 dollars depending on street, lot size and school pyramid (Redfin, 2026; Zillow, 2026).
- No verified residential lot dataset for Washington, DC appears in this source material, so any precise DC lot figure in a comparison would be unsupported.
- Builders acquired 20 of 60 sampled older McLean homes, confirming a live land market behind the residual rather than a theoretical one (Frontier Capitals, 2026).
How is a McLean lot price actually built?
A McLean lot has no independent price tag in most transactions, because vacant residential land rarely trades on its own in 22101. Instead, builders buy an older house, clear it and build, so the lot price hides inside the house purchase. Recovering it requires the residual method: begin with the finished sale the street will support, deduct the full cost of creating that house, deduct the margin a builder requires for risk and capital, and treat what remains as the ceiling for land.
Each input is observable in McLean. Finished prices come from recorded new construction sales (Redfin, 2026). Construction cost at the illustrated scale sits near 1,300,000 dollars for hard and soft items combined. The margin illustration uses a figure near 20 percent. Site preparation then takes a further 30,000 dollars to 50,000 dollars before building proper begins. Assessment and parcel records supply lot dimensions and characteristics that adjust the result up for width and level ground or down for slope and constraint (Fairfax County Department of Tax Administration, 2026).
The 42.6 percent ratio offers an independent cross check. If older homes on comparable ground average a little over two fifths of the finished price, and the standing structure contributes modest value to a buyer who plans to replace it, then most of that 42.6 percent is land wearing a house as packaging (Frontier Capitals, 2026). When the residual method and the ratio method land in a similar neighbourhood of value, a McLean owner can treat the band as credible, which is a test any Washington, DC comparison should also have to pass, with DC inputs rather than McLean ones.
An owner can watch the method operate in the deed record. Transfers followed by large replacement homes reveal which parcels builders judged worth the residual, and those deeds are searchable in the county land records (Fairfax County Circuit Court Clerk, 2026). The related study of residential lot worth inside McLean itself develops the local calculation without the cross city complication.
Why can a Washington, DC lot figure not simply be looked up here?
The honest answer is evidentiary rather than evasive. The source base for this series covers McLean sales, McLean parcels and Fairfax County records in depth, and it names the Washington-Arlington-Alexandria market only as the wider context for commission structures (National Association of Realtors, 2025). It contains no table of Washington, DC vacant lot sales, no DC builder acquisition sample and no DC residual illustration. Quoting a DC lot average from memory or general reputation would break the rule that every figure in these reports traces to a named source.
The missing inputs matter because lot economics differ by jurisdiction in ways a headline average conceals. Washington, DC parcels are shaped by a different zoning code, different lot dimensions, different historic and review overlays in many districts and a different tax and recordation structure from Fairfax County. A DC residual would need DC finished prices, DC construction costs under DC rules and DC site costs, assembled the same way the McLean residual was assembled, before subtraction produced anything meaningful.
The paperwork trail differs as well, since zoning and subdivision records for the McLean side sit with the county planning department, and any credible DC counterpart would need an equivalent record set assembled from DC offices before its lots could be scored the same way (Fairfax County Department of Planning and Development, 2026).
There is also a product difference. McLean land value is driven by quarter acre and larger parcels that accept a 6,000 plus square foot detached house, a pattern visible across the sample where typical single family parcels run a quarter acre and up (Fairfax County Department of Tax Administration, 2026). Urban lots in Washington, DC commonly support a different built form, so a per lot comparison without a per square foot or per buildable area adjustment compares unlike goods. Method, stated plainly, is the only fair bridge available in this report.
Sellers should therefore treat any confident McLean versus Washington, DC lot ranking that arrives without a DC dataset behind it as marketing rather than research. The McLean half can be priced today from the evidence above. The DC half, within this series, cannot, and the sections that follow keep that boundary visible while still giving owners a usable way to think about relative position, including how proximity to downtown Washington registers inside McLean land bids themselves (Frontier Capitals, 2026).
What does proximity to Washington, DC do to McLean lot values themselves?
Although DC lot prices cannot be quoted here, the pull of Washington, DC on McLean land is documented in the local evidence. The research file notes that proximity to downtown Washington, alongside downtown McLean, the CIA corridor and Metro access points, registers in the land bid (Frontier Capitals, 2026). In other words, part of what a McLean lot is worth is the distance between its front door and the centre of Washington, DC employment, priced through the finished homes that relocating families choose to buy.
That dynamic explains why two McLean parcels of identical size can carry different residuals. The parcel that shortens a Washington commute while keeping a sought after school pyramid supports a higher finished price, and a higher finished price flows through the residual into a higher land ceiling (Redfin, 2026; Zillow, 2026). School assignment works the same way, with premiums visible in new build closings that older listings rarely capture.
Census context for Fairfax County helps frame the buyer pool behind those finished prices, because household incomes and housing characteristics in the county sustain demand at the 2,500,000 dollar to 4,500,000 dollar level (U.S. Census Bureau, 2025). The demand is not abstract: builders acquired a third of the sampled older homes, which means the Washington oriented buyer pool is already capitalised into land bids through builder competition (Frontier Capitals, 2026).
For an owner, the practical reading is comparative within McLean rather than across the river. Rank a parcel first against other McLean lots on finished price support, pyramid and access, and only then ask whether Washington, DC land might be dearer in some general sense. The first ranking can be evidenced and acted on. The second, without a DC dataset, remains an opinion, however plausible it sounds. Owners can explore the access and position factors further in the report on which McLean areas carry the highest values.
How would a fair McLean and Washington, DC comparison be assembled?
A fair comparison would start by mirroring the McLean work on the DC side. An analyst would gather recorded sales of older homes and vacant parcels in Washington, DC over the same period, separate the acquisitions made by builders from household purchases, and compute a DC builder demand rate to set beside the McLean figure of 20 acquisitions from 60 sampled homes (Frontier Capitals, 2026). Without that sample discipline, a comparison mixes a measured McLean rate with an impressionistic DC one.
Next would come a DC residual built from DC inputs: finished prices for new detached construction on comparable lot sizes, hard and soft costs under DC permitting, a margin assumption stated as openly as the near 20 percent used here, and site preparation ranges for DC conditions. Only the outputs of two parallel residuals can be compared, because comparing a McLean residual with a DC asking price for a single lot would compare a method with an anecdote.
Adjustment would follow. Lot size, buildable area, zoning capacity and school or district assignment all differ, so the comparison would need normalising, most plausibly per square foot of land and per square foot of permitted building. Financing conditions would need stating too, since the 30 year fixed rate averaging 7.40 percent shapes household demand on both sides of the river (Freddie Mac, 2026).
Until that work exists in a citable form, the responsible statement is the one this report makes: McLean land under a typical new build is worth roughly 1,250,000 dollars to 1,450,000 dollars on the illustrated finished price, with the band moving as finished prices move between 2,500,000 dollars and 4,500,000 dollars (Frontier Capitals, 2026; Redfin, 2026). Any DC number offered to a seller should arrive with its sample, its residual and its sources attached, or be set aside.
What should a McLean owner do with a comparison that is only half priced?
Use the half that is priced, and use it fully. A McLean owner does not need a DC league table to decide how to sell, because the decision turns on the local residual, the local ratio and the local cost ledger. Frontier Capitals sources off market deals to builders and works as a wholesaler rather than a builder, matching an owner property with builders who price land by exactly the residual method described above. That makes the local calculation more than academic: it is the calculation behind live offers.
Consider the benefits in that light. Privacy heads the list, with zero showings and zero open houses, no lockbox and no sign, so a sale agreed privately stays private until the deed records. For an owner weighing a move toward or away from Washington, DC, avoiding a public marketing season also avoids broadcasting the plan before it is settled.
Timing is the second benefit, and it is flexible in both directions: closing in 7 to 21 days when a relocation date presses, or months ahead with a leaseback when a household needs time, set against 60 to 120 plus days for a listed older home once market time is counted. The third benefit is the absence of commission against the standard 5 to 6 percent, worth 80,000 dollars to 96,000 dollars on a 1,600,000 dollar sale (National Association of Realtors, 2025).
Fourth, no seller closing costs are charged, measured against the usual 1 to 2 percent for title, transfer and recordation items, with commission and closing together commonly consuming 6 to 8 percent of price. Fifth, the sale is as is, so there are no 10,000 dollar to 30,000 dollar repair credits, and none of the 15,000 dollar to 40,000 dollar inspection concession pattern typical of listed sales of older McLean homes. An owner who wants the McLean residual run on a specific parcel can telephone 401-219-4207 or email [email protected], and the firm process is described on the methodology page.
Methodology and limitations
The McLean figures derive from the 60 home sample of pre 1981 properties in 22101, from recorded new construction sales in the 2,500,000 dollar to 4,500,000 dollar range, and from the worked residual illustration, all as compiled for this series (Frontier Capitals, 2026; Redfin, 2026; Zillow, 2026). The central limitation is stated without qualification: the source material contains no residential lot dataset for Washington, DC, no DC builder sample and no DC residual, so this report compares by method and declines to publish a DC lot figure. No title search, inspection or individual appraisal was undertaken for any property discussed.
Readers should also note that the residual is a simplified illustration, sensitive to finished price, construction cost and margin in roughly equal measure (Frontier Capitals, 2026). A street where new homes clear 4,500,000 dollars supports land well above the illustrated band, while a constrained parcel may support far less, and neither case says anything verified about land across the river in Washington, DC.
Conclusion
McLean lot worth can be stated with evidence: around 1,250,000 dollars to 1,450,000 dollars beneath a 3,200,000 dollar new build on the illustrated costs and margin, moving with the 2,500,000 dollar to 4,500,000 dollar finished range and confirmed by an average older home ratio of 42.6 percent (Frontier Capitals, 2026). Washington, DC lot worth cannot be stated from this source material, and this report leaves that space deliberately blank rather than filling it with a borrowed number.
When a comparison can price only the ground you own and not the ground across the river, is the missing figure a reason to wait, or is the priced figure enough to act on?
Frequently Asked Questions
What is a typical McLean lot worth under a new build?
On the worked illustration, a finished sale of 3,200,000 dollars leaves a land residual near 1,250,000 dollars to 1,450,000 dollars after about 1,300,000 dollars of construction costs and a margin near 20 percent, before site preparation (Frontier Capitals, 2026). Streets with higher finished prices support higher land values.
Why does this report not quote a Washington, DC lot average?
Because no residential lot dataset for Washington, DC exists in the source material for this series, and inventing or borrowing a figure would misstate the evidence. The McLean side is priced from a sample and a residual; the DC side has neither in this file.
How could a seller test a DC figure someone quotes them?
Ask for the sample behind it, the finished prices and construction costs used, and the margin assumed, mirroring the disclosure given for McLean in this report. A figure that cannot show its residual arithmetic should be treated as an opinion (Frontier Capitals, 2026).
Does being close to Washington, DC raise a McLean lot value?
Yes, within the McLean evidence, because proximity to downtown Washington and to Metro access registers in land bids through higher finished prices (Frontier Capitals, 2026; Redfin, 2026). That effect is priced inside McLean without needing a DC lot dataset.
Where can a McLean owner get a parcel specific land reading?
A parcel reading starts from assessment records and recent finished sales on the street (Fairfax County Department of Tax Administration, 2026; Redfin, 2026). Deed history for neighbouring builder purchases can be checked in county land records (Fairfax County Circuit Court Clerk, 2026), and the contact page is the route to request the calculation.
