Two systems govern most of the working farms and estates that come up for sale around Middleburg, and sellers routinely confuse them. One is a permanent legal restriction recorded against the deed. The other is a tax status that has to be actively maintained, year after year, and can evaporate the moment a buyer's plans differ from the seller's. A property can carry both. A property can lose one and keep the other. And the bill that shows up at closing has almost nothing to do with which land trust holds the easement and everything to do with what the new owner intends to do with the dirt.
In August 2026, the Land Trust of Virginia announced its 283rd conservation easement, a 110-acre agricultural land easement on a property south of Warsaw. LTV is headquartered on The Plains Road in Middleburg, and it has placed more than 10,000 acres under permanent easement in Loudoun County alone. That number keeps climbing. Loudoun County's own conservation easement page now puts the countywide total above 85,000 acres, up from roughly 70,000 acres reported by the Piedmont Environmental Council in early 2024 and 67,866 acres in 2022. More land in this market gets encumbered every year, which means more buyers and sellers of Hunt Country acreage are going to run into this friction whether they're looking for it or not.
What the Easement Actually Locks In
A conservation easement is a deed restriction, not a tax program. Landowners donate or sell the development rights on their property to a qualified holder, most commonly the Land Trust of Virginia, the Piedmont Environmental Council, the Virginia Outdoors Foundation, the Northern Virginia Conservation Trust, or Old Dominion Land Conservancy. In exchange, the land can never be subdivided beyond whatever limited number of divisions the easement document specifies, structures are capped, and the restriction runs with the title forever. It survives every future sale. A buyer who closes on an eased farm inherits the exact same limits the seller lived under, regardless of what the buyer paid or what they'd hoped to build.
That permanence is the entire point, and it's why families choose it. It's also the part that gives owners real income tax deductions, potential state tax credits, and estate planning benefits, since a qualified donation reduces the taxable value of the land. None of that changes hands based on who owns the property next. The easement doesn't ask what the buyer plans to do. It already told them.
What the Tax Program Actually Defers
Separately, Loudoun County runs a Land Use Assessment Program that lets farmland, forest, horticultural, and open-space land get taxed at its use value rather than its fair market value. This is where most of the confusion starts, because unlike a conservation easement, land use assessment is not permanent and it does not attach to a specific legal restriction on the land. It's a status, and it has to be renewed. Owners must reapply every sixth year, with renewal packets mailed the first week of September and due without penalty by November 1. Miss that date and a $300 late fee per parcel gets added to the standard $125-plus-$1-per-acre filing fee, with a hard cutoff on December 5.
There's also a sliding scale option some owners layer on top. A landowner who commits in writing to keeping the property in its qualifying use for 10 to 20 years can defer 99 percent of the use-value taxes for that term. A 5-to-10-year commitment defers 50 percent. Those commitments get recorded with the county clerk, which means a buyer doing title work will find them, but a buyer who isn't looking specifically for them can miss what that commitment implies about what happens if they don't honor it.
The Moment Title Changes Hands
Here's where the two systems diverge in a way that matters more than most closing checklists account for.
The conservation easement doesn't care who owns the land. The tax program does, because it's tied to active use, not to legal restriction. Whenever land enrolled in the Land Use Assessment Program changes to a non-qualifying use, or gets rezoned to something more intensive, or is subdivided beyond what the qualifying use allows, the county assesses roll-back taxes. Loudoun's ordinance defines the number precisely: the difference between the land-use value and the fair market value for the current tax year and the five years before it, plus simple interest of five-sixths of one percent per month on the deferred amount. On acreage that's been carrying a use-value assessment for years while its fair market value climbed, that six-year gap plus accruing interest is not a rounding error.
The reporting window is short. Whoever changes the land's use, whether that's the seller before closing or the buyer right after, has 60 days to report it to the Commissioner of the Revenue. If a seller's farm has been in the program and the new owner intends to keep farming it, the seller needs to hand over proof of production going back to the last renewal so the buyer can step into that status without a gap. If the new owner has no intention of continuing the qualifying use, that has to be reported within 60 days and an estimate of roll-back taxes requested. Either way, the clock starts at closing, not at the next tax cycle.
| Conservation Easement | Land Use Assessment Program | |
|---|---|---|
| What it is | Permanent deed restriction on development | Renewable tax status tied to active use |
| Who holds it | A qualified land trust (LTV, PEC, VOF, and others) | Loudoun County Commissioner of the Revenue |
| Does it survive a sale | Yes, automatically and forever | Only if the buyer continues the qualifying use |
| What triggers a bill | Nothing. There's no tax mechanism attached | A change of use, rezoning, or subdivision |
| Renewal required | Never | Every sixth year, by November 1 |
Why the Easement Doesn't Save You from the Rollback
This is the piece that trips people up on eased Hunt Country farms specifically. An easement restricting subdivision does not automatically enroll the land in the tax program, and being in the tax program does not require an easement. A property can have both, either, or neither. A buyer purchasing 150 acres under a Land Trust of Virginia easement might assume the conservation restriction covers the tax question too. It doesn't. If that same buyer plans to stop active farming and simply hold the land as a private retreat, that shift alone can trigger the roll-back calculation, easement or no easement. The legal protection on the land and the tax treatment of the land are answering two different questions, and a sale forces an answer to both at once.
Loudoun County's Conservation Easement Assistance Program adds one more wrinkle worth knowing about before an offer goes in. The county reimburses up to $25,000 in qualifying expenses, appraisal, attorney fees, processing costs, when a landowner places new acreage under easement, with $150,000 available annually on a first-come basis. A seller who used that program to defray the cost of granting an easement has already been through the legal and appraisal work a buyer would otherwise have to underwrite themselves. That's worth asking about directly rather than discovering during due diligence.
What to Check Before You Write an Offer or List a Farm
For a buyer looking at eased or use-value acreage in Middleburg or the wider Hunt Country market, a few questions belong in the offer stage rather than after ratification:
- How many subdivision rights, if any, remain under the recorded easement, and who holds it
- Whether the property is currently enrolled in the Land Use Assessment Program and when it last renewed
- Whether the owner has signed a 10-to-20-year sliding scale commitment, since breaking that early carries a steeper roll-back exposure than a standard enrollment
- Whether the seller can produce documentation of qualifying production for the years since the last renewal
- What the buyer's own post-closing plans imply for roll-back liability, independent of what the seller was doing
For a seller, the conversation is really about timing the 60-day reporting window and having production records ready so a continuing buyer doesn't lose time reestablishing status the property already earned.
A conservation easement and a land use assessment status are not interchangeable protections. They are two separate systems layered on the same acreage, and only one of them asks what happens next.
A Few Questions Worth Asking Directly
Does a conservation easement expire or get renegotiated at sale? No. It's permanent and transfers with the title regardless of who buys the property or what they intend to do with it.
Can eased land still qualify for the Land Use Assessment Program? Yes, the two are independent. An easement restricting development doesn't automatically enroll land in the tax program, and enrollment doesn't require an easement.
If I buy a farm already enrolled in land use assessment, do I inherit the tax status automatically? No. The new owner has to continue the qualifying use to keep the status, and has 60 days to report if they won't.
What determines whether a sale triggers roll-back taxes? The buyer's actual use of the land after closing, not the presence or absence of a conservation easement.
If you're weighing an offer on acreage in Middleburg or Hunt Country, or getting ready to list a farm that's carried either of these designations for years, it's worth walking through exactly what transfers automatically and what has to be actively continued before you put a number on paper.
