What McLean's Last Undeveloped Acres Reveal About Every Home Price in Town

For more than sixty years, a quiet stretch of land off Lewinsville Road belonged to one family. A manor house built in 1875 stood on the property along with stables, a swimming pool, and a tennis court. When patriarch Freeborn Garrettson died there in October 2022 at age 94, the estate passed out of the Jewett family's hands for the first time in generations. It sold in October 2024 to an affiliate of Petroleum Marketing Group, and by late 2025 every structure on the site had been cleared.
What's rising in its place says more about McLean's real estate market than any median-price headline. The property, now called Knolewood, has been split into 24 lots ranging from 0.82 to 1.2 acres, with wide tree-lined streets ending in two cul-de-sacs. Individual lots have listed for $2.45 to $2.5 million each, sold as raw land before a single house exists on them, with buyers required to build with one of three approved firms: Artisan Builders, Galileo Signature, or Winthrop Builders.
That's not a typo and it's not a pre-construction discount. That's the price of dirt.
Knolewood is the clearest current example of something that's been true across McLean for years but rarely gets said plainly: in this market, the sale price increasingly reflects the land, not the structure sitting on it. A house can be dated, cramped, or outright torn down without moving the number much, because the number was never really about the house.
This matters for anyone trying to make sense of a McLean listing. A 1960s rambler on a half-acre lot in a strong school pyramid can command a price that has almost nothing to do with its kitchen, its bathrooms, or its 1970s floor plan. The buyer isn't purchasing square footage. They're purchasing a position: the lot, the address, and everything zoning allows them to build on it later.
Builders working in McLean use a rough threshold to decide whether a given house is a renovation candidate or a teardown candidate. Once projected renovation costs approach roughly 70 percent of what it would cost to replace the home entirely, rebuilding usually wins on pure economics.
The logic plays out house by house:
That threshold is why so much of McLean's older inventory is disappearing, one lot at a time, rather than being remodeled room by room.
"Building new allows us to tailor a home to the property and the family," says Jason Furtek, director of construction at Monarch Custom Homes. "We're not constrained by the limits of an old structure. Instead, we can optimize for natural light, flow, and functionality, which makes a lasting difference in how a home lives."
Drive through Chesterbrook or parts of Old Dominion Gardens and you'll pass brick ramblers and modest colonials originally built for military officers and government executives in the 1950s through 1980s. Many of those homes have mature landscaping and solid bones, but their kitchens, bathrooms, and mechanical systems reflect a different era of daily life. Increasingly, they're candidates for teardown rather than repair.
A few miles away, in neighborhoods like Langley Forest, Langley Oaks, Hansborough, and McLean Hamlet, the housing stock skews slightly newer, larger colonials from the 1960s and 1970s on bigger lots. Those homes tend to be structurally solid, which is why whole-house renovation is still the more common path there. Franklin Park, Salona Village, and West McLean sit somewhere in between, with established neighborhoods that continue to produce teardown opportunities on quarter-acre and half-acre lots.
None of this is a single McLean market. It's a patchwork of micro-decisions, each one running the same 70 percent math against a different house.
McLean's median sale price crossed $2 million in October 2025, even as the number of homes sold declined year-over-year and days on market increased, according to Redfin data reported by FFXnow. Taken alone, that combination looks contradictory: prices rising while fewer homes change hands and each one sits longer. Read against the land-value thesis, it makes sense. Buyers weren't disappearing. They were becoming more selective, willing to pay top-tier prices for lots and locations that checked every box, while passing on homes that felt dated or compromised.
By the three months ending May 2026, the picture had tightened again. McLean's median sale price stood at $1.9 million, up 9.7 percent year-over-year, with a median price per square foot of $466, up 7.7 percent. Homes were selling in an average of 19 days, down from 26 days the year before, and 181 homes sold that month, matching the prior year's pace.
The swing between those two windows isn't the market changing its mind. It's the mix of what sold changing. When a handful of high-value, well-positioned lots and new builds close in a given month, they can move the median more than the underlying market actually shifted, since McLean's monthly sales counts are small enough that a few transactions carry outsized weight. That's exactly the dynamic Knolewood is about to accelerate: 24 lots hitting the market at once, priced well above what a raw parcel would fetch in most of Northern Virginia, in a submarket where land has become the scarce input.
If your house falls into that 1960s or 1970s bracket, with an outdated layout or systems nearing the end of their life, the most useful question isn't "what did the last renovated home in my neighborhood sell for." It's "what is a builder willing to pay for this lot, in this school pyramid, on this street." Pricing strategy for a teardown-adjacent property looks different from pricing a move-in-ready one, and comps drawn from the wrong category will mislead both the seller and the buyer.
Fairfax County's permitting process adds another layer sellers should understand before listing. McLean is unincorporated Fairfax County, so any teardown-rebuild project runs through the county's Department of Land Development Services, requiring separate demolition permits, new construction permits, and grading or land-disturbance permits. Properties near streams face additional review under the Chesapeake Bay Preservation Ordinance for Resource Protection Areas. None of that changes what a lot is worth, but it does shape how quickly a buyer can act on it, which is worth knowing before you set expectations for a fast close.
Price per square foot is a useful number until it isn't. Two McLean homes at the same price per square foot can represent entirely different purchases if one sits on a buildable half-acre lot in a sought-after pyramid and the other sits on a compact lot with less long-term flexibility. If you're weighing options across neighborhoods, ask less about the finished square footage in front of you and more about what the lot itself will support, now and later.
Does this mean older McLean homes have no value? No. A structurally sound home in good condition still commands a premium for the livable space it offers today. The land-value dynamic is strongest in the segment of homes where renovation costs are already approaching that 70 percent replacement threshold.
How do I know if my home is a renovation candidate or a teardown candidate? It comes down to the condition of the foundation, mechanical systems, and layout relative to what a full rebuild would cost on the same lot. A local agent who tracks recent land and new-construction sales in your specific neighborhood can help you see where your home falls on that spectrum before you commit to either path.
Does the land-value logic apply to condos and townhomes too? Less directly. Attached properties don't carry the same teardown economics since buyers aren't purchasing a standalone lot. Value there tends to track building quality, HOA health, and proximity to walkable amenities more than raw land.
