A homeowner on Waxpool Road spent thirteen years building a life around his backyard pool and fire pit before he started hearing a low hum some nights that he initially mistook for bass from a neighbor's stereo. It wasn't music. It was one of the data centers now flanking his subdivision, Regency, on two sides. Over the past several months, a developer has offered him and his 142 neighbors roughly $4.4 million per acre to sell, a deal that would total more than half a billion dollars if every household agreed to it.
Sixty miles of fiber and a few zip codes away, a different Ashburn homeowner opened her 2026 tax bill and found the county's real property rate sitting at $0.805 per $100 of assessed value, the lowest in Northern Virginia and a rate that has fallen every single year since 2016. Those two stories read like unrelated local news items. They aren't. They're the same arithmetic, arriving at two different addresses.
The Same Number, Read Two Ways
Loudoun County's property tax rate has dropped from $1.145 per $100 of assessed value in 2016 to $0.805 in 2026, a decade of consecutive cuts that county officials point to as proof of fiscal discipline. The real driver is more specific than discipline. A 2026 report prepared by Mangum Economics for the Northern Virginia Technology Council modeled what would happen if data centers vanished from the county's tax rolls tomorrow. The residential rate would need to climb to roughly $1.537 per $100, a 91 percent increase that would add about $5,800 a year to the bill on a median-valued Loudoun home.
That gap exists because data center revenue now covers somewhere between 38 and 42 percent of the county's local tax funding, depending on which analysis you read. The county's own FY2026 budget figures put it at 38 percent of General Fund revenue. A separate estimate from the Loudoun County Preservation and Conservation Coalition puts data centers at closer to 42 percent for 2026, up from about 33 percent in 2024, with total data center tax payments rising from roughly $700 million in 2024 to a projected $1.14 billion this year.
Here's the part that matters for anyone comparing suburbs: only about 4 percent of Loudoun's commercial parcels carry nearly half the local tax load. A finished data center brings almost no new students and few ongoing workers relative to the tax revenue it generates. Board of Supervisors Vice Chairman Mike Turner has made the same point publicly, noting that data centers don't add kids to schools or cars to roads the way a housing subdivision does. County estimates put the cost of servicing a data center at about four cents for every tax dollar it generates, versus roughly 25 cents for ordinary commercial property. That mismatch, high revenue, low service cost, is the entire mechanism behind Loudoun's falling rate.
| Year | Loudoun real property tax rate (per $100 assessed value) |
|---|---|
| 2016 | $1.145 |
| 2026 (actual) | $0.805 |
| 2026 (without data center revenue, modeled) | $1.537 |
The benefit from that arithmetic spreads evenly across every homeowner in the county. The cost does not. It concentrates on specific streets.
The Corridor Where the Numbers Get Personal
Drive Route 7 or the Dulles Greenway through Ashburn and you pass the buildings that make the tax math work: windowless, beige or gray, ringed by chain-link fencing and backup generators, lit at night with a steady industrial glow. For homes at a comfortable distance, that infrastructure is invisible except on a tax bill. For homes that share a property line with it, the experience is different. One Ashburn resident was told a 185-foot high-voltage transmission tower, part of the grid buildout needed to power new capacity, could be built behind her house. A health assessment published this year in Frontiers in Climate documented measurable noise and air quality effects for residents living close to data center campuses, effects the researchers characterized as legitimate and relevant to local policy.
Loudoun County has responded to some of this friction directly. On March 18, 2025, the Board of Supervisors adopted Comprehensive Plan and zoning ordinance amendments specifically intended to place new controls on where and how data centers can be built, an acknowledgment that the county's own growth had outpaced its original zoning framework. The political pressure hasn't stopped. In July 2026, Algonkian District Supervisor Juli Briskman introduced a motion proposing a moratorium on new data center construction, a sign that the rules governing this corridor are still being actively negotiated rather than settled.
For a buyer comparing two similar homes in Ashburn, this is the detail that a median price alone won't tell you. The countywide tax advantage applies to both listings equally. The proximity risk, the noise, the pending infrastructure, the zoning uncertainty, does not.
Why the Regency Deal Isn't a Preview for Every Street
The Regency offer is worth understanding precisely because it's easy to misread as a template. The Regency homeowners' association formed an LLC specifically to negotiate the sale as a bloc, and the numbers only work if all 143 households agree, since a handful of holdouts can stop rezoning from moving forward at all. As of the most recent public reporting, no formal application to redevelop the site had been filed with the county, and Board Chair Phyllis Randall has indicated she has serious reservations about approving that kind of development there.
Precedent from next door offers a caution. In Prince William County, more than 200 landowners tried to assemble roughly 2,000 acres for a project called the Dulles South Innovation Center, which would have been the largest data center development in that county's history. The Board of Supervisors rejected it unanimously. Zoning approval for these deals is not a formality, and the process from offer to closed transaction can run years even when every owner wants to sell.
The lesson for a Loudoun seller isn't that a buyout offer is coming for every neighborhood near a data center corridor. It's that these deals move on a political and regulatory timeline, not a market one, and betting a sale strategy on the possibility is speculative rather than a plan.
Due Diligence Before You Write an Offer in Ashburn
The countywide tax rate tells you almost nothing about a specific parcel's exposure. Before making an offer on a home in or near the Data Center Alley corridor, it's worth checking a few things directly rather than relying on the listing description:
- Pull up Loudoun County's own data center information page and cross-reference the property against known and proposed facility locations, not just what's visible from the street today.
- Ask whether any nearby parcel has an active or pending rezoning application, since the 2025 zoning amendments changed the approval process and not every project in the pipeline is public knowledge yet.
- Check for planned substation or transmission line filings in the immediate area, since new capacity often requires grid infrastructure well before a data center itself breaks ground.
- Compare total holding cost, not just the county rate, since HOA dues in newer Ashburn communities can offset some of the tax savings that make the headline number attractive.
- If a neighborhood sits directly adjacent to an existing facility, ask how appraisers and recent buyers in that specific pocket have handled comparable sales, since proximity effects tend to be hyperlocal rather than uniform across a zip code.
None of this shows up in a portal search filtered by bedrooms and price. It shows up when someone who tracks this market pulls the county's own records and reads the zoning calendar alongside the comps.
A Few Direct Questions
Does living near a data center always lower a home's resale value? Not automatically. What the research shows consistently is a narrower buyer pool for homes with direct visual or noise exposure, which can affect time on market and negotiating leverage more predictably than it affects a fixed price discount.
Could Loudoun's tax rate go up if the data center boom slows? It's possible, though the county has more room to raise commercial rates before residential ones. Loudoun currently taxes data center equipment at $4.15 per $100, lower than Fairfax's $4.57 and Prince William's $4.50, and county officials have noted the industry hasn't pushed back on that rate, which suggests room to adjust commercial rates before residential ones would need to move.
Is a buyout offer like Regency's likely to happen in other Ashburn neighborhoods? It's possible but not predictable. These deals depend on a specific mix of adjacent land availability, HOA organization, and county rezoning appetite, and Prince William's rejected Dulles South project shows the outcome is never guaranteed even when landowners are willing sellers.
The tax bill and the buyout offer are the same story told from opposite ends of the corridor. Understanding which end your address sits on is worth more than knowing the county average.
