The Edgemont Median That Isn't Telling You What You Think

In the first quarter of 2026, the median sale price in Edgemont rose 75 percent. Next door, in the Village of Scarsdale, the median rose 4 percent. Set those two numbers side by side and Edgemont looks like the market to watch, the place where values are suddenly breaking loose while Scarsdale plods along.

That reading is wrong, and the reason it's wrong tells you almost everything you need to know before comparing the two places.

Edgemont's median jumped because 10 homes sold there in the first quarter of 2026, down from 11 in the same period a year earlier. Scarsdale's median moved 4 percent because 25 homes sold, the same count as the prior year. A market of 10 transactions can be reshaped by one large sale. A market of 25 is still thin by national standards, but it absorbs outliers better. The 75 percent figure isn't a signal about Edgemont's desirability. It's what happens to a median when the denominator is small.

That's the transaction-level trap. There's a second one sitting underneath it, and it has nothing to do with sample size.

Edgemont isn't a place with a government. It's a school district with a mailing address.

Ask a title company or a tax assessor where Edgemont is, and the answer gets more specific than most buyers expect. Edgemont, sometimes recorded as Greenville, is a census-designated place inside the Town of Greenburgh. It has never been an incorporated village. There's no mayor, no independently elected board of trustees, no Edgemont municipal government making local zoning calls. The name that shows up on listings and mail comes from ZIP code convention, not from any unit of government: most of the area carries a Scarsdale, NY 10583 address, and a portion uses Hartsdale, NY 10530. Neither ZIP code belongs exclusively to Edgemont, and neither one makes Edgemont part of the Village of Scarsdale, which sits entirely outside the CDP's boundaries.

What Edgemont does have, consistently and for decades, is its own school district. The Edgemont Union Free School District runs three schools: Edgemont Junior/Senior High School, Greenville Elementary, and Seely Place Elementary. It has ranked in the top 20 percent of school districts statewide, with math and reading proficiency well above New York averages, and Niche's 2026 rankings placed it among the state's A-plus districts alongside Scarsdale, Chappaqua, and a short list of other Westchester systems. On the school question, the comparison to Scarsdale is a fair one. Both districts are excellent, and a buyer choosing between them is choosing between two strong options, not a strong one and a weak one.

The governance question is where the comparison stops being fair, because one side of it has been unsettled for almost a decade.

A vote that keeps almost happening

Residents in favor of incorporating Edgemont as Greenburgh's seventh village have tried this before. Petitions filed in 2017 and 2019 were both struck down in court on procedural grounds, the kind of technical defects, an incomplete list of inhabitants, an insufficiently precise description of the territory, that sound minor until they cost a coalition years of effort. In 2023, New York overhauled its village incorporation law statewide, adding a required fiscal and operational study and a new state review commission before any referendum can proceed. Edgemont's advocates worried the tighter process would end their effort before it started, and state legislators negotiated a carve-out: Edgemont received an exemption letting it attempt incorporation one more time under the older, simpler rules, good through 2040.

That third attempt reached a head in March 2026, when a state Supreme Court judge ruled, for the third time in this long-running fight, that Edgemont residents should be allowed to vote on incorporation, with a referendum ordered within roughly 40 days. Town Supervisor Paul Feiner responded the way he had after the two previous rulings: he announced the Town would appeal, arguing the petition still failed to meet the legal requirements of state Village Law. By May 2026, the Greenburgh Town Board had approved additional funds to continue the legal fight, pushing the town's cumulative legal spending on the Edgemont incorporation question to roughly $400,000 across this decade-long dispute, according to reporting by veteran Westchester journalist David McKay Wilson.

As of the most recent public reporting on the case, from May 2026, no referendum had taken place and the Town's appeal was still pending. History offers a reasonable guide to what happens next: the Town has prevailed on procedural grounds twice before, and Feiner has said publicly that he expects the same outcome this time.

The stakes explain why both sides keep fighting. A 2024 feasibility study from the Center for Governmental Research modeled a one-year post-incorporation scenario in which Edgemont's own tax burden stays roughly neutral if the new village contracts efficiently for services, while the rest of unincorporated Greenburgh absorbs an estimated 0.6 percent tax increase to cover the lost revenue. Assemblymember MaryJane Shimsky argued at the time that a one-year estimate doesn't account for litigation costs, unresolved questions about water infrastructure and debt service, or how a new village would handle shared assets like the Hartsdale Public Parking District and the Greenburgh Nature Center. Supporters, including longtime advocate Jeff Sherwin and Edgemont resident Michael Goldstein, have argued that the current arrangement leaves the neighborhood without a government that answers directly to it. Both positions are reasonable. Neither has been tested by an actual vote.

What's stable and what isn't

Zoom out to the wider 10583 ZIP code and the picture blurs further. Zillow's June 2026 estimate put the typical home value across all of 10583 at roughly $1.32 million, up 2.6 percent year over year. That figure blends Scarsdale village properties with Edgemont properties under one ZIP-level number, which is exactly the kind of aggregation that makes a genuinely useful comparison harder to see. A buyer relying on ZIP-level data alone can't tell which side of the municipal line a given price reflects.

What this means if you're actually comparing the two

If Edgemont and Scarsdale are both on your list, the sale price isn't where the real difference sits. A few things worth working through before you write an offer:

• Treat the Edgemont median with caution until the sample grows. Ten sales is not enough to establish a trend. Ask about comparable sales in the specific price band and house type you're considering, not the neighborhood-wide median.
• Separate the school question from the government question. The Edgemont Union Free School District's track record is well established and doesn't depend on the outcome of the incorporation fight. Municipal services, zoning authority, and long-term tax structure do.
• Follow the litigation, not just the listing. The incorporation case is active, and as of the most recent reporting the Town's appeal was still pending. Whatever happens will shape how local decisions get made in Edgemont for years, and it's worth understanding where things stand before you commit to a timeline.
• Confirm which government actually serves the property. A Scarsdale mailing address on a listing doesn't tell you whether the home sits inside the Village of Scarsdale or in unincorporated Greenburgh. Your closing attorney or title search will confirm it, but it's worth asking early.

A short FAQ

Is Edgemont part of the Village of Scarsdale? No. Edgemont is an unincorporated area of the Town of Greenburgh. It shares a ZIP code convention with the Village of Scarsdale, but the village's boundaries don't include Edgemont, and Edgemont has never had its own incorporated government.

If Edgemont incorporates, will my property taxes change? Possibly, but the honest answer right now is that no referendum has occurred and, as of the most recent public reporting, the Town's appeal is still working through the courts. Fiscal projections exist, but they cover a single post-incorporation year and carry real uncertainty around litigation costs, shared infrastructure, and how services would actually be contracted.

Are Edgemont schools the same as Scarsdale schools? No. Edgemont children attend the Edgemont Union Free School District, a separate system from the Scarsdale Union Free School District, though both are highly regarded and both have earned top statewide marks.

Buyers who treat Edgemont and Scarsdale as interchangeable because of a shared ZIP code are missing the part of the comparison that actually matters.
