A residential lot in Falls Church is worth what the finished house on it can support, and on the worked figures in the underlying research that support runs from about $850,000 to $1,050,000 for a lot that can carry a $2,200,000 new build (Frontier Capitals, 2026). Start from that sale price, subtract roughly $800,000 to $900,000 in hard and soft construction costs and a builder margin near 20 percent, and the remainder is the land value before site-preparation costs of $25,000 to $50,000 (Frontier Capitals, 2026).
Not every lot reaches the top of that range, and some smaller inside-the-Beltway parcels in 22046 trade in a different band than the quarter-acre-plus parcels that form the standard builder inventory in 22043. What does not change is the method. Builders in this submarket acquired 18 of 44 sampled older homes, so lot pricing here is not theoretical (Frontier Capitals, 2026). It is a live, repeated market with its own arithmetic, and a seller who learns that arithmetic stops guessing at land value from the assessed figure alone.
Frontier Capitals works that market as a wholesaler, sourcing off-market deals to builders rather than building on its own account. That position is why this report explains the builder calculation openly: a seller who can follow the subtraction can judge any land offer that arrives.
Key Findings
- The residual illustration in the research leaves $850,000 to $1,050,000 for land on a $2,200,000 new build, after $800,000 to $900,000 in build costs and a margin near 20 percent (Frontier Capitals, 2026).
- Site-preparation costs of $25,000 to $50,000 come off the land figure before a final bid is set (Frontier Capitals, 2026).
- Minimum lots in the sample were 10,010 sq ft in 22043 and 6,000 sq ft in 22046, and quarter-acre-plus parcels are the standard builder unit in 22043 (Frontier Capitals, 2026).
- Older homes traded at a houses-weighted average of 31.2 percent of the comparable new build price, 31.0 percent in 22043 and 31.6 percent in 22046 (Frontier Capitals, 2026).
- New construction on comparable lots sells from $1,600,000 to $3,000,000 depending on street, lot size and proximity to Metro (Redfin, 2026) (Zillow, 2026).
How does the residual method turn a finished price into a lot price?
Builders do not price land by comparing one empty parcel with another, because empty parcels almost never trade in a built out place like Falls Church. They price backwards from the house they intend to sell. The first number is the expected finished price, taken from real new build sales on comparable lots, which in this submarket run from $1,600,000 to $3,000,000 (Redfin, 2026) (Zillow, 2026). A lot on a street where the last new house cleared $2,400,000 starts its calculation hundreds of thousands of dollars ahead of a lot where the comparable finished price is $1,700,000.
From that finished price the builder subtracts the cost of creating the house. The research illustration uses roughly $800,000 to $900,000 for hard and soft costs together, a range that reflects the construction cost pressure builders keep citing nationally, where single-family starts were running at a 918,000 seasonally adjusted annual rate (National Association of Home Builders, 2026). Then the builder subtracts a margin near 20 percent, because a project that cannot protect its margin through a rate move or a slow sale will not be started at all.
What survives those subtractions is the most the builder can pay for the ground and still have a workable project, $850,000 to $1,050,000 on the $2,200,000 example (Frontier Capitals, 2026). Site costs then trim the bid: clearing, grading, utility work and similar preparation at $25,000 to $50,000 come out of the land side. A seller who is shown a land offer without this walk-through is being asked to trust a number. A seller who sees the four lines can argue with any one of them, which is a far stronger position. The related question of how much a builder will pay for an older house in Falls Church applies the same subtraction to houses that are still standing.
Why do two lots a few streets apart carry such different values?
Street level finished prices explain most of the spread. New build premiums tied to Metro access and to inside-the-Beltway position show up clearly in new construction prices, while older home listings on the same streets often fail to reflect them (Redfin, 2026). A lot that feeds a $2,600,000 finished sale can support a land price far above a lot feeding a $1,800,000 sale, even if the two parcels measure the same. The premium is documented in the source material as real; what the material does not provide is a single percentage for it, and this report does not invent one.
History compounds the street effect. Builders pay more where they have built before, because their cost assumptions on those streets are proven rather than estimated. A builder who has already carried a project through permitting and sale on your street knows the soil, the reviewers and the buyer response, and can bid with less contingency held back. Parcel and permit records show where that replacement activity has concentrated (City of Falls Church Real Estate Assessment Office, 2026).
The city and county context matters too. Falls Church is small and essentially built out, and federal place data for the surrounding county describes a dense, high income market where new land supply is close to fixed (U.S. Census Bureau, 2025). When no new lots are being created, the value of an existing buildable lot is set by competition among builders for a fixed pool, which is why 18 of 44 sampled older homes ended with builders (Frontier Capitals, 2026). Scarcity is not a slogan here; it is the supply side of the residual equation.
How do 22043 and 22046 lots differ in what they are worth?
The two ZIP codes offer builders different raw material. In 22043, on the Fairfax County side, the sampled subdivisions are 1950s and 1960s brick ranch neighborhoods built for federal workers, with a minimum lot of 10,010 sq ft and quarter-acre-plus parcels as the standard unit (Frontier Capitals, 2026). Ten of 26 sampled homes there went to builders, a rate of 38.5 percent, and the average older home price was 31.0 percent of the new build price (Frontier Capitals, 2026). Land value in 22043 is driven by usable area: width for a modern footprint, depth for a yard, and room for a garage that current buyers expect.
In 22046, the inside-the-Beltway side, the housing stock runs to Cape Cods and ramblers on lots as small as 6,000 sq ft, yet 8 of 18 sampled homes went to builders, a rate of 44.4 percent, and the older home ratio was slightly higher at 31.6 percent (Frontier Capitals, 2026). There, position does the work that acreage does across the line. A smaller lot in 22046 can be worth as much as a larger one in 22043 if the finished house on it commands the inside-the-Beltway price.
For a seller, the lesson is to resist pricing a lot by size alone. County assessment records carry a land line for every parcel in the Falls Church area, and comparing that line with neighboring parcels of similar dimensions is a useful first screen (Fairfax County Department of Tax Administration, 2026). But assessments lag the builder market and do not capture street level finished prices. Use the assessment to establish the parcel facts, then use the residual method to establish the value. The broader treatment in how much lot size affects property values in Falls Church separates the live-in effect of size from the builder effect.
What costs and duties come with selling a house as a lot?
A seller who sells to a builder is still selling a house in the eyes of Virginia disclosure law until the deed records. Most sellers must deliver a Virginia Residential Property Disclosure Statement under Virginia Code section 55.1-700 et seq., giving yes, no and unknown answers about the condition of the property, and an honest unknown creates no liability while a wrong no can (Virginia Realtors, 2026). As-is language in the contract does not waive that duty, so the form should be completed carefully even when everyone at the table expects the house to be replaced.
The transaction costs, though, are where the lot route separates itself from a listing. A listed sale of the house at $700,000 carries commission at 5 to 6 percent, or $35,000 to $42,000, under typical Northern Virginia structures (National Association of Realtors, 2025). It also carries seller closing costs of another 1 to 2 percent, buyer concessions and repair credits that often run $10,000 to $25,000 on older inventory, and carrying costs of $15,000 to $35,000 over three to six months of market time. Those lines explain how a $700,000 list price nets in the high $500,000s to low $600,000s after a normal cycle.
A direct land sale strips out the commission and the seller closing costs, and because the buyer wants the ground, it also strips out the repair negotiation. The seller keeps the difference between the gross figures that headlines celebrate and the net figures that actually arrive. That is why the honest comparison is never lot price against list price; it is net against net, as the method in how Falls Church homeowners can determine whether a property is worth more as land sets out step by step.
Verification protects the seller at the end of the process. Recorded deeds in a buyer entity name can be checked in county land records, and a genuine direct buyer closes in the name on the contract with no assignment clause and earnest money of 1 percent or more at risk (Fairfax County Circuit Court Clerk, 2026). Proof of funds dated within the last 30 days completes the picture.
One further distinction is worth making before the benefits are counted, because it changes how offers should be read. A lot price and a house price are not two names for the same asset arriving by different routes. The lot price already assumes the cost of removing what stands on the parcel and preparing the ground, which is why it can be quoted firmly and closed quickly, while a house price remains exposed to appraisal, financing and inspection findings that reprice it late in the process. A seller comparing the two should therefore discount the house price for its contingencies, not just for its printed costs, and should treat a firm land figure as the more certain of the two numbers even when it is not the larger one.
What do sellers keep when a Falls Church sale stays off market?
The first thing kept is quiet. A lot sale arranged privately involves no showings, no open houses, no lockbox and no public marketing period, and nothing becomes public until the deed records. Neighbors learn about the sale when the seller chooses to tell them, not when a sign goes up.
The second is control of the calendar. A direct closing can be completed in 7 to 21 days when a seller needs speed, or it can be scheduled months ahead with a leaseback so a family can finish a school year or a move in an orderly way. Set that against the 60 to 120 plus days a listed older home commonly spends reaching closing, and the value of choosing your own date becomes concrete.
The third and fourth are cash lines. With no commission, the seller keeps the 5 to 6 percent that would have gone to agents, worth $35,000 to $42,000 on a $700,000 sale (National Association of Realtors, 2025). With no seller closing costs charged, the seller also keeps the 1 to 2 percent those costs usually consume, and on a $650,000 transaction commissions and closing costs together commonly exceed $40,000. On a lot sale at the figures in this report, the percentage savings apply to a much larger gross, so the dollars kept grow accordingly.
The fifth is freedom from the repair economy. An as-is direct sale carries no inspection driven second negotiation and no $10,000 to $30,000 repair credit or reduction demanded after acceptance. For a house being bought for its ground, that is only logical: the buyer is not purchasing the furnace, the wiring or the roof, and does not price them as if they mattered.
Methodology and limitations
The figures here trace to the sample compiled for the builder demand study, 44 older homes across 22043 and 22046 with 18 acquired by builders, and to city and county parcel, permit and assessment records (Frontier Capitals, 2026) (City of Falls Church Real Estate Assessment Office, 2026) (Fairfax County Department of Tax Administration, 2026). Finished price ranges come from recent sold and new construction data for the two ZIP codes (Redfin, 2026) (Zillow, 2026).
Three limitations should be kept in view. The land range is a simplified illustration built on a $2,200,000 finished price, not an appraisal of any specific parcel, and a lot that supports only a $1,600,000 finished price will support proportionally less land value. No individually named new build sale appears in the Falls Church source material, so none is cited. And the Metro proximity premium, while documented, is not quantified as a percentage in the material, so street level judgment still has to come from actual comparable finished sales. Sellers can review how the study area is defined through the coverage page for this research before applying the range to a particular address.
Conclusion
A Falls Church lot is worth the residue of a successful new build on that lot: finished price, minus construction cost, minus margin, minus site work. On the research figures that residue runs $850,000 to $1,050,000 for a lot carrying a $2,200,000 house, with 22043 land priced mainly on generous dimensions and 22046 land priced mainly on inside-the-Beltway position. The number for any given parcel is knowable, but only by running the subtraction with that parcel facts, not by borrowing a neighbor price per square foot.

If the ground beneath your house can support a figure near the top of that range, what would you need to see, in writing, before you believed it?
Frequently Asked Questions
Is the county assessed land value a good guide to what a builder will pay?
It is a starting point, not an answer. Assessment records establish parcel dimensions and a land line for tax purposes (Fairfax County Department of Tax Administration, 2026), but they lag the market and ignore street level finished prices. Builders bid from the residual method, which is why their offers can sit well above the assessed land figure.
Does a bigger lot always mean a higher land price?
Usually, but not automatically. In 22043, quarter-acre-plus parcels are the standard builder unit and width changes what can be built (Frontier Capitals, 2026). In 22046, a 6,000 sq ft lot inside the Beltway can rival a larger parcel because position lifts the finished price. Size matters through the finished house it allows, not in isolation.
Who pays the site-preparation costs on a lot sale?
In the research illustration, site costs of $25,000 to $50,000 are treated as a deduction from what the builder can pay for land, so they are effectively priced into the offer rather than billed to the seller (Frontier Capitals, 2026). A seller should confirm in writing that no separate site charges appear later in the transaction.
Can I sell the lot and keep living in the house for a while?
Yes, that is a common structure in a direct sale. Closings can be set months out with a leaseback, so the seller remains in the house for an agreed period after the sale or before moving. The dates are written into the contract, which is one reason sellers with complicated moves choose this route.
What if my house is worth more to a family than the land is to a builder?
Then the live-in market should win your business, and a good analysis will tell you so. The older home ratio of 31.2 percent is an average (Frontier Capitals, 2026); a genuinely appealing, well kept house near Metro can beat its land value. The point of pricing the lot is to know both numbers before you commit to either buyer.
