Loudoun County Farms & Land

What Loudoun County Land Is Like

Loudoun splits into two very different halves, and the dividing line matters more than the county line itself. The eastern part of the county, closer to Dulles and Ashburn, is the heart of Virginia's data-center belt: dense, valuable, and increasingly built out. The western half, protected under the county's rural policy area designation, is still genuinely rural: rolling farmland, horse country, and small towns like Middleburg, Purcellville, and Lovettsville that have kept their agricultural and equestrian character.

That split shows up directly in land values and in who is buying. Eastern Loudoun land gets priced against its development and data-center potential. Western Loudoun land gets priced as farmland, estate property, and equestrian real estate, a market that has more in common with Fauquier than with the rest of Loudoun.

What Sells and Who Buys

Vacant land in Loudoun sold at a median of roughly $525,000 to $542,000 in 2024–25, with 44 to 77 land sales a year. Equestrian and estate-style farms in the western county typically trade between $1.5 million and $8 million, with outliers reaching as high as $19 million for the largest or most prominent properties.

Buyers in western Loudoun are largely equestrian and estate buyers, along with working farm operations and buyers drawn to the county's protected rural character. Ordinary rural land here has been appreciating in the mid-single digits to high-single digits annually, the county's 2026 assessment put rural land gains at roughly 5.9% to 8.6%, a steady but unspectacular pace next to what land with a genuine data-center path can do.

The Data-Center Picture in Loudoun

Loudoun is the epicenter of Virginia's data-center economy, and the numbers reflect it. Per county assessment records and local press reporting, data-center-zoned land averaged $3.76 million per acre in the county's February 2026 assessment, up $1.4 million per acre from the year before, a pace with no real analog in ordinary rural land anywhere in the corridor. Data centers now make up roughly 26% of the county's entire real-estate tax base. A 97-acre Leesburg property sold for $615 million, about $6.3 million per acre, the record for the region, and a developer offered roughly $4.4 million per acre for a roughly 130-acre neighborhood assemblage in Ashburn in March 2026.

That is the eastern-county story, and it is not the western-county story. Ordinary Loudoun farmland, even in a hot market, appreciates in single digits a year, the gap between a data-center-zoned acre and an ordinary rural acre in the same county is not a modest premium, it is a different order of magnitude. See how data-center land values compare to ordinary land across the region for the full picture.

The county's own posture toward more data-center growth is shifting. The Board of Supervisors voted 6–1 to have staff draft a pause option on new data-center applications, with a staff report due September 15, 2026, though the County Attorney has advised that a true moratorium is likely not legal under Virginia's Dillon Rule, which limits what localities can restrict without specific state authorization.

Land-Use Taxation and Zoning in Loudoun

Loudoun land enrolled in land-use (use-value) assessment follows the standard Virginia rollback rule: recapture of the five most recently completed tax years of deferred tax, plus interest, if the land changes to a non-qualifying use. Selling to a buyer who keeps the land in a qualifying agricultural use does not, by itself, trigger rollback. See how rollback taxes work in Virginia for the full mechanics.

On conservation, Loudoun's Purchase of Development Rights (PDR) program has been written into the county ordinance since 1999 but has gone unfunded since 2004, so unlike Fauquier's active PDR program, Loudoun landowners don't currently have a county cash-purchase option for development rights, though donated conservation easements through VOF, PEC, or a land trust remain available with the state tax credit. See how conservation easements work for the details.

Selling Land or a Farm in Loudoun

Where a Loudoun property sits relative to the eastern data-center belt versus the western rural policy area is the single biggest driver of how it should be marketed and priced. A parcel with genuine proximity to power infrastructure, substations, or an active data-center corridor is a fundamentally different sale than a horse farm in Middleburg or Lovettsville, with a different buyer pool, valuation approach, and timeline.

For western-county sellers, the ordinary due-diligence items still apply: confirming land-use enrollment and rollback exposure, and for raw land, perc and well status before listing. See perc tests and wells in Virginia for what to check before you list undeveloped acreage.

Buying Land or a Farm in Loudoun

Buyers should be clear-eyed about which Loudoun they're shopping in. Western Loudoun offers genuine rural and equestrian character, protected by the county's rural policy area designation, at pricing that reflects farmland and estate value rather than development potential. Eastern Loudoun land, where it borders the data-center corridor, trades on an entirely different basis and is not comparable to western-county farmland on a price-per-acre basis.

Anyone considering land near the data-center belt, whether to hold, farm, or eventually explore an offer, should understand the difference between an option agreement and an outright sale before engaging with a developer. See what a data-center offer on your farm actually means.
