Pull up two real estate sites in the same week and search "Chatham, NY." One will tell you the median home sold for $308,832 in June 2026, down nearly 8 percent from a year earlier. Another will tell you homes in a Chatham neighborhood are listing for a median of $2.29 million, sitting on the market for 111 days. Same town name. A sevenfold gap in price.
Neither number is wrong. That's the part buyers relocating from the city tend to miss. The two sites aren't disagreeing about what Chatham is worth. They're answering different questions using different maps, and the place name "Chatham" happens to sit on top of all of them.
What Each Number Is Actually Measuring
Redfin's countywide and city-level figures aggregate sales across a broad Chatham footprint, which is why the June 2026 median of $308,832 reads low: it's blending starter homes, land parcels, and modest village houses into one number. Zillow's neighborhood-level index for the hamlet of Old Chatham, inside that same footprint, put the typical home value closer to $562,013 as of mid-2026, while Zillow's broader Chatham zip code figure landed at $446,708. Movoto's listing data for Old Chatham specifically showed a median list price of $2.29 million in July 2026, with homes sitting a median of 111 days before going under contract.
Here's the comparison in one place:
| Source and date | Geography measured | Reported figure |
|---|---|---|
| Redfin, June 2026 | Chatham citywide aggregate | $308,832 median sale price, down 7.8% year over year |
| Zillow, mid-2026 | Chatham zip code | $446,708 typical home value |
| Zillow, mid-2026 | Old Chatham hamlet | $562,013 typical home value |
| Movoto, July 2026 | Old Chatham hamlet | $2.29M median list price, 111 days on market |
A separate market analysis, drawing on local MLS activity for the broader Chatham area, put the more typical figure closer to $495,000 to $510,000, with days on market running 90 to 130 and appreciation holding a steady 2.5 to 3.3 percent a year. That number sits almost exactly between the low aggregate and the high hamlet figure, which is the clue to what's actually going on. Nobody's number is broken. Each one is measuring a different slice of the same town, and the slices don't nest cleanly inside each other.
The Village That Belongs to Two Towns
The reason the slices don't nest goes back to how Chatham was drawn on the map, not to anything happening in the market this year. The Town of Chatham sits at the northern edge of Columbia County and contains a scatter of named hamlets: Old Chatham, East Chatham, Chatham Center, North Chatham, along with smaller settlements like Rock City and Malden Bridge. Each of these has its own postal identity and, increasingly, its own price tier.
The Village of Chatham, the walkable downtown with the traffic light, the Crandell Theatre, and the Mac-Hadyn Theater where Nathan Lane once performed in summer stock, isn't fully inside the Town of Chatham at all. The village straddles the town line, with its northern half and central business district in the Town of Chatham and its southern half in the neighboring Town of Ghent. So when a portal reports a "Chatham" number pulled by zip code, it may be capturing village households governed by two different town assessors, plus outlying hamlet properties, plus rural parcels on well and septic, all under one label. When a portal reports a hamlet-specific number for Old Chatham, it's isolating a much smaller, much more expensive slice: a settlement of historic farmhouses and larger lots that has functioned for decades as one of the county's higher-end enclaves, home to the Old Chatham Sheepherding Company since 1993.
This is not a Chatham quirk born of clever branding. It's an artifact of how Hudson Valley towns were settled, subdivided, and named well before anyone was building a housing data platform. But it means a buyer comparing "Chatham" to "Hudson" or "Kinderhook" on a portal is often comparing a blended number to a single number, without realizing the blend is doing most of the work.
Old Chatham's Estate Lots Against Main Street's Walkable Blocks
The price gap tracks a real difference in what you're buying, not just a data quirk. In the Village of Chatham, the housing stock clusters along Main Street, with Victorian-era brick storefronts anchoring a corridor where a car becomes optional for errands, dinner, or a movie at the Crandell. Lots here are village-sized. Water and sewer are municipal. The appeal is proximity: you can own a modest, well-kept house and still be a five-minute walk from the Columbia County Agricultural Society's fairgrounds and the shops that keep Main Street occupied.
Old Chatham reads differently. It's one of the town's earliest settlements, and its housing stock reflects that: larger parcels, more standalone farmhouses and estate-scaled properties, longer driveways, private wells rather than a municipal system. Buyers drawn to Old Chatham are often the same buyers who'd consider a country estate anywhere else in Columbia County, and the price data reflects that they're bidding against each other for a smaller pool of larger properties rather than against village buyers for a starter house on Payn Avenue.
Neither market is objectively better. They're built for different buyers, which is exactly why treating them as one number produces bad comparisons.
The Friction That Shows Up After the Offer
The village-versus-hamlet split isn't just a pricing curiosity. It shapes the due diligence timeline, too. Village properties on municipal water and sewer skip an entire category of pre-closing inspection. Rural hamlet properties, including much of Old Chatham, East Chatham, and the outlying parts of the town, rely on private wells and septic systems, and New York's disclosure requirements for those systems tightened for sales closing in 2025 and 2026. That means well flow tests, septic inspections, and system age documentation now factor into a rural Chatham closing timeline in a way they simply don't for a Main Street village purchase.
Add to that the age of the housing stock. Much of Chatham's inventory, village and hamlet alike, dates to the 1800s. That's part of the appeal for buyers drawn to character and craftsmanship, but it also means budgeting for a full inspection that specifically checks for knob-and-tube wiring, lead paint, and asbestos in anything built before 1978. A buyer moving from a newer city condo into a 19th-century Old Chatham farmhouse is taking on a different inspection scope than a buyer moving into a recently updated village house two blocks from the Crandell, even if both properties are technically "in Chatham."
What This Means If You're Comparing Columbia County Towns
If you're weighing Chatham against Kinderhook, Ghent, or Hudson using numbers pulled from a portal, the number itself is less useful than knowing what boundary produced it. Before you compare a "Chatham" median to anything else, ask three questions: Is this a zip code aggregate, a town-level figure, or a hamlet-specific number? Does it include the part of the Village of Chatham that actually sits in the Town of Ghent? And is the days-on-market figure describing a starter home turning over quickly, or an estate-scaled Old Chatham property sitting for three or four months while it finds the right buyer?
None of this means the low number or the high number is the "real" Chatham price. It means Chatham was never one market to begin with, and the fastest way to get a useful comparison is to ask for hamlet-level or even street-level comps rather than trusting whatever boundary a search box happened to draw.
A Short FAQ
Is Old Chatham the same place as the Village of Chatham? No. Old Chatham is a hamlet inside the Town of Chatham, several miles from the Village of Chatham's Main Street. They share a name but not a housing stock, price tier, or utility infrastructure.
Why does the Village of Chatham straddling two towns matter to a buyer? It means two houses a few blocks apart in the same village can fall under different town governments, which can affect which assessor values your property and which town board you'd deal with on local matters. It's also part of why zip-code-level price data blends more than buyers expect.
Should I trust the countywide median or the hamlet-specific number? Neither in isolation. Use the countywide figure to understand the broad trend and the hamlet-specific figure to understand what a particular property type actually costs. Comparing one to the other, rather than picking a favorite, is what gives you a usable answer.
What should I ask when a listing says simply "Chatham, NY"? Ask which hamlet or which side of the village line the property sits on, whether it's on municipal or private water and septic, and how old the structure is. Those three answers tell you more about likely price and closing timeline than the town name ever will.
Columbia County rewards buyers who read past the headline number, and Chatham is the clearest example of why that discipline pays off.
