Three structures, one steady market — the county in miniature. This August no tier ran away and none broke down; the whole corridor’s seasonal turn showed up in Fairfax as small shifts in terms, not a swing in values.
Data Source: BrightMLS (closed sales & inventory) · Freddie Mac (mortgage rates) · Hud’s Compass proprietary behavioral market intelligence.
Three numbers set the frame. Mortgage rates held near 6.7% all month — essentially flat from a year ago. Fairfax detached carries a median of $950K; its condominiums, $350K. On the headline, a steady market: rates flat, prices holding, all three tiers within a point or two of where they sat a year ago. But read the terms underneath, and the tiers are quietly trading places — townhomes firming, condos building supply, detached holding its premium.
Start with supply and demand. Each panel tracks two lines: active listings (homes for sale — supply) against pending sales (homes under contract — demand). When the supply line pulls away from the demand line, the market is loosening in the buyer’s favor. Fairfax’s three tiers barely separated — which is the point.

The calendar explains the gentleness. The corridor runs on a school-year clock: families compete hard through spring, close before the buses roll, then the buyer pool quiets — not gone, just no longer racing. That seasonal handoff cooled estate tiers hard in Reston, McLean and Great Falls this August. In Fairfax it barely registered: detached eased just over a point, townhome actually firmed, and condo held flat. Fairfax took the turn gentler than anywhere on the corridor.
No tier ran away, and none broke down. Fairfax absorbed the season on terms, not on values —
which is exactly what the county’s most balanced market is supposed to do.
ONE COUNTY, THREE TIERS — ALL WITHIN A HAIR OF FLAT
Here is what makes Fairfax the county in miniature: this August the Compass scored its three tiers Townhome 73.2, Detached 71.2, Condominium 66.2 — a seven-point band, and every one of them within two points of where it sat a year ago. Where Reston split three ways and McLean’s estate tier dropped thirteen points, Fairfax hardly moved. The tiers diverge on terms — who’s conceding, who’s holding — but the market as a whole is as balanced as any on the corridor. Read Fairfax as the steady middle.
The clearest gauge is the Contract Ratio — pending sales divided by active listings. At 1.0, supply and demand balance; below it, inventory piles up faster than buyers absorb it. It turns months before closed prices do, which makes it the earliest honest signal you can get.

The year-over-year picture is a quiet swap. A year ago townhome led at 0.75 and condo trailed at 0.37; this August they traded places — condo firmed to 0.75 while townhome eased to 0.36, and detached held steady near 0.63. All three sit below balance, so the whole county tilts modestly toward the buyer — but no tier is in free-fall, and the demand that left townhome didn’t leave the market, it moved to condo.
HUD’S COMPASS — NORTHERN VIRGINIA’S ONLY MARKET INTELLIGENCE INDEX
Conditions data tells you what is coming — supply, demand, the direction of pressure. Anyone with an MLS login can pull it. The Compass tells you why — it reads the behavior behind the closings, scoring four needles from every closed sale. And the read tells you how to act. This month’s Fairfax report reads the closed side: why detached held full ask at a rising premium, why townhome buyers suddenly gave far less at the table, and why the condo tier stayed flat while its inventory grew.
One teaching point unlocks the rest. Most people watch sale-to-list price — but a list price is just an asking number a seller can type at will. Watch sale-to-assessed instead: the county’s assessed value is a fixed anchor that doesn’t move with a seller’s optimism. When a home clears above assessed with no concession, real demand paid up. When it tests high on list, then closes below it with money back at the table, the price was a wish the condition couldn’t support.
Detached — the steady anchor, holding its premium
Fairfax detached is the county’s anchor, and this August it barely bent. Homes sold at a median $950K, cleared in just nine days, and closed at exactly 100% of list — full ask, while pricier cities’ estate tiers slipped below. The Compass scores it 71.2, dead flat from a year ago, with Power at 54 (above the county) and Velocity at 86.
Read the terms honestly: concessions ticked up to 36% from 16% a year ago, and above-list sales eased from 45% to 39% — the seasonal buyer gave a little less of a premium. But the assessed gradient shows why sellers hold firm: the typical detached cleared 112% of assessed value, up from a year ago, and Fairfax detached carries +36% cumulative equity since 2020. On 75 sales — the most robust cell of any corridor city this month — this is a seller who can price to today and still command the number.

The premium is intact and the equity is real. Price to today’s comps, show it clean, and Fairfax detached still clears in a week.
Townhome — the mild gainer, firming on terms
The townhome tier was the month’s quiet winner — the only structure to gain ground, up to 73.2, the highest score in Fairfax. Homes sold at a median $746K, at 100% of list in ten days, with Strategy and Intensity both at 80.
The tell is in the terms: concessions fell from 43% to 25% — the biggest terms improvement in the county. Buyers competed on the number and gave far less back at the table than a year ago. There’s a caveat worth naming — active listings climbed from 64 to 89, so the contract ratio eased to 0.36 even as the tier firmed on price. Supply is building underneath a disciplined, firming market: the well-priced townhome still sells near full value, but it now sits in a longer line.

Price it right and the Fairfax townhome is a compete-not-negotiate buy — but with supply building, the reaching listing waits.
Condominium — dead flat on the score, building underneath
The condo tier held almost perfectly steady on the score — 66.2, essentially unchanged — but the inventory moved. Homes sold at a median $350K, at 98.9% of list in about three weeks, with concessions easing slightly to 37%.
Underneath the flat score, two things firmed and one built. Demand firmed — the contract ratio jumped to 0.75 from 0.37 a year ago as pendings rose. But supply built faster: active listings climbed from 67 to 100, pushing months of supply to 3.95. The assessed gradient reads steady at 103%, and the tier carries +21% cumulative equity since 2020 — condos hold value more than they compound. The net: a stable entry tier with real room for the patient buyer, where below-list sales now run near 58%.

Steady demand, growing supply — the patient condo buyer has both time and room this fall.
FOR SELLERS
The market still pays full value for the right home — but “the right home” now means priced to today and shown move-in ready. Fairfax’s three tiers each ask something a little different of you.
DETACHED: Your equity is real — +36% since 2020 — and you still hold pricing power: full-list sales, nine-day speed, a rising premium over assessed. Price to today’s comps, show it clean, and it moves fast. The buyer gives a little more at the table than a year ago, so build a modest concession into your number rather than your asking price.
TOWNHOME: You’re in the firming tier — concessions have been cut nearly in half. But supply grew by a third this year, so you’re pricing into a longer line. Price to the market and the disciplined listing still sells near full value; reach, and it sits.
CONDOMINIUM: Inventory is building — nearly four months of supply — so prep and price matter more than ever. A unit that shows well and needs nothing beats a cheaper unit that needs work, because your buyer has options and time. Price realistically and expect a measured negotiation.
FOR BUYERS
Fairfax is the balanced market — no tier is cheap, none is on fire, and all three tilt modestly your way on terms this fall.
DETACHED: This is the firm one. Full-list sales clearing in nine days on real equity — sellers aren’t discounting. Your room is in terms — a concession, closing help — more than deep cuts off a well-priced home. Bring your strongest offer on the ones that show well.
TOWNHOME: A little more room opened as supply grew, but this tier is firming on terms, so your window is tightening. Move on the right home rather than waiting for softer concessions — they’re already shrinking.
CONDOMINIUM: You have the most room here. Nearly four months of supply, below-list sales near 58%, and a tier flat on value. Ask for concessions, ask for repairs, and read the sale-to-assessed column to see what buyers actually paid against the county’s anchor.
One number to keep next to your offer: Fairfax detached carries +36% cumulative appreciation since 2020, and the pace has normalized across all three tiers. Offer at today’s level, let the appraisal set the ceiling, and you own an asset instead of an anchor.
WHAT’S NEXT
The leading indicators point to a fall that keeps favoring the prepared buyer and the disciplined seller — gently, across all three tiers, which is Fairfax’s signature.
Contract Ratio — the demand gauge — sits below balance in every structure, but none is collapsing: detached steady near 0.63, condo firming to 0.75, townhome easing to 0.36 as its supply grows. Until these turn back up, expect terms to keep favoring buyers county-wide.

Months of Supply tells the same story from the inventory side: detached stays tight near 1.3 months, townhome has risen to about 2, and condo has built to nearly 4 — a gentle, tier-by-tier loosening rather than a county-wide glut.

Fairfax is the county in miniature — and this August it did what a balanced market does: absorbed the season gently, easing on terms rather than values. The detached tier holds its premium, the townhome tier firmed as buyers gave less back, and the condo tier stayed steady while its supply grew. Read Fairfax tier by tier, and you’ll know exactly which deal you’re in.
Curious what your Fairfax home is really worth this fall?
The median won’t tell you — your tier, your home’s condition, and where you price against assessed value will. That’s the read I bring: not an online estimate, but the behavioral market intelligence behind every closing in your neighborhood. Whether you’re weighing a sale, a purchase, or just want to know where your equity stands, let’s talk.
