Why Pleasantville NY Home Prices Look So Different

Check four different sources for Pleasantville home prices this year and you will get four different stories. One shows the median sale price climbing 27.5 percent over the past year. Another, tracking the exact same zip code just a few months earlier, shows it falling 15.5 percent. A third puts the median down in the single digits. A fourth, using a different kind of calculation altogether, shows prices basically flat with modest single-digit growth.

None of these numbers is wrong. That is the part worth sitting with if you are comparing Pleasantville to other Westchester villages and trying to figure out what is actually happening to prices here. A village this size does not produce enough sales in any given month for a median to behave like a thermometer reading. It behaves more like a coin flip that happens to have dollar signs attached. Understanding why changes how you should read any single number you see for this market, and for a lot of small Westchester towns like it.

Four Trackers, One Village

Here is what four different sources reported for the same corner of Westchester County, all within the past year.

Zillow's home value index measures something closer to an estimated value across the entire housing stock than a median of homes that actually sold in a given window. The Redfin and Homes.com figures are raw medians of homes that sold within their respective time windows, and their reported changes vary widely. That difference between an estimated-value index and raw sold-price medians is the first clue to what is actually going on.

Where the Volatility Actually Comes From

Pleasantville had 7,513 residents at the last census. It is a small village, and it simply does not turn over that many homes in any given month. Redfin counted 23 closings in the village for July 2026 and 16 in the 10570 zip code for March 2026. Homes.com counted 73 sales across the entire trailing 12 months, which works out to roughly six closings a month.

At that volume, the median can be sensitive to which homes happened to close in a particular window. A period with more recently renovated colonials on the north side and fewer smaller capes near the train tracks could push the median higher; a different mix of closings the following month could pull it down, even without a change in what buyers are willing to pay for a comparable house.

One local brokerage's market tracker made this almost comically visible. In an April 2026 breakout of Pleasantville sales by property type, the entire condo and co-op category for that month totaled three units. At three sales, adding or losing a single transaction from one comparison period to the next swings the year-over-year percentage by dozens of points. The same report showed that identical three-unit month posting year-over-year changes as different as a 25 percent decline and a 200 percent increase, depending on which metric and which prior period each line was measured against. Nobody made an error. Three is just too small a number to generate a stable percentage.

The Zip Code Is Bigger Than the Village

There is a second reason these numbers diverge, and it has nothing to do with sample size. The Village of Pleasantville and the 10570 zip code are not the same shape.

Pleasantville sits inside the Town of Mount Pleasant, and most of the village is served by the Pleasantville Union Free School District. But the northern edge of the village falls into the Chappaqua Central School District, and the section of Pleasantville commonly called "The Flats" is mostly served by the Mount Pleasant Central School District instead, according to Wikipedia's entry on the village. The zip code stretches beyond the village's own municipal boundary into unincorporated pockets of the surrounding town, meaning a search for "10570" pulls in inventory the Village of Pleasantville itself would not count as one of its own addresses, and vice versa depending on which tool draws the line.

That is why Redfin's village-level number and its own zip-code-level number for roughly the same period can point in opposite directions. They are not disagreeing about Pleasantville. They are counting different houses.

What the Countywide Numbers Actually Tell You

If village-level medians are this noisy, where should a buyer or seller actually look for signal? The county level, where enough transactions happen every month to smooth out the coin-flip problem.

Westchester's countywide single-family median sales price reached $999,000 in February 2026 according to OneKey MLS data, up 16.2 percent from the same month a year earlier, with months of supply at just 1.4. That kind of figure, built on hundreds of closings across dozens of towns rather than a handful in one village, moves in a way that actually reflects shifting demand and constrained inventory rather than the particular mix of homes that happened to close in one village. Federal Reserve data on Westchester County new listing activity tells a similar story of persistently limited new supply feeding into that pressure, and you can review the monthly counts yourself through the St. Louis Fed's public series on Westchester County housing inventory.

The lesson is not that Pleasantville's own numbers are meaningless. It is that the village-level dollar figure tells you what a house here might actually cost you today, while the county-level trend tells you which direction the broader market is leaning. Confusing the two, treating a one-month village swing as if it carries the same weight as a countywide trend, is where buyers get spooked or oversold on momentum that is not really there.

What to Do With This If You're Comparing Towns

If you are cross-shopping Pleasantville against Chappaqua, Briarcliff Manor, or another nearby village, a single year-over-year percentage should never be the deciding factor. Ask instead how many homes that number is based on. A median built on 23 sales deserves more trust than one built on three. Ask whether the figure covers the village proper or a wider zip code, since the difference in Pleasantville alone can run from under $850,000 to over $1.1 million depending on which boundary you use. And look at price per square foot across several months rather than a single one, since that metric tends to hold steadier than the median when the pool of closings is this small.

None of this means Pleasantville is unaffordable or overheated. It means the headline number you saw on a portal home page is a snapshot of a handful of transactions, not a verdict on the whole village.

A Few Straight Answers

Does this mean Pleasantville home values aren't really rising? Not necessarily. It means a single month's median in a village this size is too noisy to answer that question on its own. Looking at price per square foot trends over several months, alongside the broader Westchester County direction, gives a steadier read than any one portal's headline figure.

Why do the Village of Pleasantville and zip code 10570 give different numbers for what sounds like the same place? The zip code extends into unincorporated parts of the Town of Mount Pleasant that sit outside the village's own boundary, including areas served by a different school district. A search built around the zip code counts homes the village-level search does not, and the reverse is also true.

Should I ignore online estimate tools entirely when I'm comparing Westchester towns? Use them as a starting point, not a verdict. They are most useful for understanding the general range a town falls into and least useful for making a call about month-to-month momentum in a market this small.

Every one of these numbers is a real snapshot. None of them is the whole picture.
