New Hampshire's seller disclosure law is oddly precise about some things and silent about others. A seller has to tell you, in writing, about the water supply and sewage system on the property, including malfunctions and the date of the last test. They have to disclose the type and location of insulation. State-mandated language covers radon, lead paint, and arsenic in well water, all spelled out under RSA 477.
It says nothing about airport noise. Nothing about avigation easements. If you are looking at a home in the stretch of Londonderry that sits under Manchester-Boston Regional Airport's flight paths, or backs up against the Pettengill Road logistics corridor, that gap in the paperwork is yours to close. The seller isn't required to hand it to you.
What New Hampshire Actually Requires Sellers to Tell You
The disclosure checklist is real and specific, but it was written around a handful of known risks common to New Hampshire homes generally: private wells, septic systems, older insulation, and a few environmental hazards the legislature singled out by name. It was not written with airport-adjacent parcels in mind, and it shows. A buyer reading a standard New Hampshire disclosure form can walk away feeling like every risk has been covered, when one of the most relevant risks for a specific address near MHT was never on the list to begin with.
The Backstop Is a Person, Not a Form
New Hampshire does have a second layer of protection, but it works differently than the checklist. Real estate agents carry a duty under RSA 331-A:25-b to disclose any material condition affecting the property that they actually know about. That word matters. The water test date is required no matter what anyone happens to know or remember. An avigation easement, a noise complaint history, or a recorded aviation-related restriction only gets flagged if someone involved in the transaction already has that knowledge and thinks to mention it.
That is a meaningfully weaker guarantee for a buyer. A listing agent who has never worked a file near the airport, or who genuinely doesn't know a parcel carries a recorded easement, has nothing to disclose because there is nothing in their head to disclose. The form won't catch it either. This is the actual gap in the process, and it is why a buyer looking near the airport corridor has to do a little more work than a buyer looking at a comparable home three miles away in a quieter part of town.
Londonderry's own zoning ordinance treats this land differently, which is a clue worth paying attention to. The ordinance opens its airport-related section by simply defining "Airport" as "the Manchester Airport," then goes on to carve out separate definitions for airside and landside areas within an Airport District governed by its own set of rules. The town's regulatory framework already acknowledges that this part of Londonderry isn't like the rest of it. The standard sale paperwork just hasn't caught up to that acknowledgment.
Two Airport Stories Are Happening at the Same Time
Here's where it gets more complicated than a simple noise warning. Manchester-Boston is living through two contradictory trends right now, and a buyer who only pays attention to headlines about one of them will draw the wrong conclusion.
| Passenger side | Cargo side | |
|---|---|---|
| 2025 activity | Roughly 1.4 million passengers, the highest total since before the pandemic | More than 119,000 tons of freight handled, a record for the airport |
| Recent changes | JetBlue flew its last departure from MHT on July 8, 2026, following Avelo's pause and Spirit's earlier exit | UPS, Amazon Air, and FedEx together account for the bulk of that cargo volume |
| Operating pattern | Concentrated in daytime departure and arrival windows | Built around overnight delivery schedules, not passenger convenience |
A buyer touring a home on a Saturday afternoon this fall is seeing the passenger side of that table, and the passenger side has been shrinking all year. It would be reasonable to walk away from a showing thinking flight activity near the property is easing. The cargo side tells a different story, and it's the side that actually determines how quiet a night in that neighborhood is. Overnight freight runs on a schedule set by retail delivery windows, not by what's convenient for a showing at 2 p.m. That mismatch between what a buyer sees during a tour and what a resident actually lives with is the single biggest reason to treat this as a due diligence item rather than a gut check.
Why the Cargo Side Keeps Growing
The freight growth isn't an abstract industry trend passing through. It's anchored to a specific piece of Londonderry. The Pettengill Road corridor, sitting adjacent to the airport, has been developing since 2015 and now counts UPS, FedEx, Milton CAT, and a New Balance manufacturing plant among its tenants. Airport leadership has pointed directly to that industrial park as a driver behind the cargo increase, tying local jobs and freight volume together in a way that a passing news cycle can't easily reverse the way it just reversed passenger service.
That's worth sitting with for a moment, because it cuts both ways. The same corridor that generates overnight cargo traffic is also generating employment and tax base for the town, which supports property values and services across Londonderry more broadly. This isn't a story about a neighborhood in decline. It's a story about a specific kind of growth that shows up differently depending on whether you're looking at a jobs report or standing in a backyard at 11 p.m.
What to Actually Verify Before You Write an Offer
None of this means avoiding homes near the airport corridor. It means doing the specific homework the standard paperwork won't do for you.
- Order a title search early in the process and ask directly whether it identifies any recorded avigation easement on the parcel, rather than waiting for it to surface at closing.
- Contact Londonderry's Building & Zoning Enforcement office at 268B Mammoth Road and ask whether the specific address falls within the zoning ordinance's Airport District.
- Ask whatever public noise information exists for that flight corridor rather than relying solely on what comes up during a showing.
- Visit the property at more than one time of day, including an evening, since cargo operations run on a different clock than the daytime tour schedule.
- Ask neighbors or the current owner directly about typical overnight activity before you're several weeks into a purchase contract.
Every one of those steps takes a phone call or a visit, not a lawyer. But they're the steps that turn a disclosure gap into information you actually have before you're financially committed.
This is the kind of groundwork that matters more the closer a property sits to that corridor, and it's exactly where having someone who has walked this specific due diligence before pays off. Julie McMaster's background working alongside a builder means she's used to reading a property for what the paperwork doesn't say, not just what it does, and that habit applies just as much to an airport easement question as it does to a foundation detail.
A Few Questions Worth Asking Directly
Does every home near Manchester-Boston Regional Airport have an avigation easement? No. Easements are specific to individual parcels and their history, not a blanket condition across the whole area. A title search is the only reliable way to know whether a particular address carries one.
Would an easement or documented noise history affect financing? It isn't automatically disqualifying, but a recorded easement can affect resale value and how comparable sales are read down the line, which is exactly why it's worth knowing before you're deep into a contract rather than discovering it at closing.
Where do I find the town's Airport District boundaries? Londonderry's Building & Zoning Enforcement office at 268B Mammoth Road maintains the zoning maps and can confirm whether a specific parcel falls inside that overlay district.
