That is the direct answer, and we will show the work behind it. But the more useful question, and the one almost nobody answers honestly, is this: what does “sells the most homes” even mean? In residential real estate that phrase gets attached to at least three different measurements, and the three do not produce the same winner. A team can lead a market on transaction count and trail it badly on dollars. Another can lead on dollars and have closed six deals. A third can lead on listings taken and have sold almost none of them.

This page explains how market share is actually calculated in Nassau County, why the definition of “Roslyn” changes the answer before you have counted a single sale, what a seller should reasonably conclude from a volume claim, and the five questions that settle any agent’s numbers in about two minutes. Our own record is in here, stated plainly and sourced. The measurement framework matters more, because it is what lets you check anyone, including us.

What Does “Sells the Most Homes” Actually Mean?

Every production claim in residential real estate resolves to one of three underlying measurements. Agents rarely say which one they are using, and the omission is usually the point.

Closed Sides: The Transaction Count

A “side” is the industry’s unit of transaction credit. One home sale produces two sides: a listing side, representing the seller, and a buyer side. If the same agent represents both parties, that agent is credited with two sides. If two agents co-list, each is generally credited with half a side. Sides are the cleanest measure of how many transactions an agent or team actually carried, which is why MLS production reports and industry rankings are usually built on them.

What sides do not tell you is price. A side is a side whether the home traded at $600,000 or $6 million. An agent with 40 sides in a market of modest co-ops has done more transactions, and less dollar business, than an agent with 12 sides of Gold Coast estates.

Closed Volume: The Dollar Count

Closed volume sums the sale prices of every transaction credited to an agent or team over a period. This is the measure RealTrends uses for its Large Teams by Volume ranking, and it is the measure most luxury markets default to, because in a market where a single sale can exceed $5 million, dollars describe the business more accurately than unit count.

Volume has the opposite blind spot from sides. A team that closed a small number of very large sales can post an impressive volume figure while having limited recent experience in the $1 million to $2 million range where most Roslyn and East Hills listings actually transact. Volume answers “how much did they sell,” not “how often have they done what I am about to do.”

Listings Taken: The Inventory Count

Listings taken counts signed listing agreements, sold or not. It is the loosest of the three, because it measures what an agent was hired to sell rather than what they sold. A high listings-taken number with a low closed-side number is a signal worth understanding: it can mean an agent wins listings on price promises the market does not support. The seller-relevant version of this figure is the sold ratio, meaning listings closed divided by listings taken, and it is a fair thing to ask for.

Measurement	What it counts	What it hides	Best used for
Closed sides	Transactions carried, listing side and buyer side counted separately	Price point and dollar scale	How often a team actually transacts in your specific market
Closed volume	Total sale dollars over a period	How many deals, and at what price points	Scale of business and luxury-tier experience
Listings taken	Signed listing agreements	Whether those listings ever sold	Nothing on its own, until paired with the sold ratio

How Is Market Share Measured in Roslyn and East Hills?

Nassau County transactions are recorded in OneKey MLS, which is owned and operated by the Long Island Board of Realtors and the Hudson Gateway Association of Realtors. OneKey describes itself as the ninth largest multiple listing service in the United States, with more than 43,000 Realtor members and coverage across Long Island, the Hudson Valley, Manhattan, and parts of Connecticut and New Jersey. Any legitimate market-share number for Roslyn or East Hills starts there.

The calculation itself is simple arithmetic. Pull every closed transaction inside a defined geography over a defined date range, sum the sides or the volume for the agent or team in question, and divide by the total for everyone. The arithmetic is not where claims go wrong. The inputs are.

The Roslyn Problem: There Are Several Different Roslyns

Before you count a single sale, you have to decide what Roslyn means, and the available definitions are wildly different in size.

The incorporated Village of Roslyn was incorporated on January 11, 1932, sits in the Town of North Hempstead, covers roughly 0.66 square miles, and recorded a population of 2,988 in the 2020 United States Census. It is small enough that a market-share claim scoped to the village line can rest on a very small number of closings.

The 11576 ZIP code, which the Postal Service also labels Roslyn, is far larger and includes addresses in East Hills, Roslyn Estates, Roslyn Harbor, and beyond. The Roslyn Union Free School District is a third boundary again: it covers the villages of Roslyn and Roslyn Estates entirely, and parts of East Hills, Flower Hill, North Hills, Roslyn Harbor, Greenvale, and Roslyn Heights. And “Greater Roslyn,” the phrase most buyers actually mean when they type Roslyn into a search bar, is an informal market area with no legal boundary at all.

Those four definitions can each be reasonable. They cannot all produce the same market-share number. A team can be the leader inside the village line and not inside the school district, or the reverse. This is why the geography input has to be stated, and why a claim without one is unfalsifiable.

East Hills Adds a Second Layer

The Village of East Hills was incorporated on June 24, 1931, covers roughly 2.28 square miles, and recorded a population of 7,284 in the 2020 Census. It lies primarily within the Town of North Hempstead, with a small northeastern section inside the Town of Oyster Bay.

School assignment inside East Hills varies by address. Most of the village is in the Roslyn Union Free School District. Southeastern portions are in the East Williston Union Free School District, and the section inside the Town of Oyster Bay is in the Jericho Union Free School District. That is a factual boundary matter, not a judgment about any district, and buyers and sellers should always verify the assigned schools for a specific address directly with the district office.

For market measurement, the consequence is straightforward: an East Hills sales count filtered by school district and an East Hills sales count filtered by village line are not the same dataset. Any team that reports on East Hills needs to say which filter it used.

Why Does It Matter to a Seller Who Sells the Most?

It matters less than the marketing implies, and more than the skeptics allow. Here is the honest version.

Volume is a proxy for repetition. A team closing a high number of transactions inside one small market is pricing against comparable sales that closed weeks ago rather than months ago. It has watched how a specific street, a specific era of construction, or a specific lot condition actually trades, not how a portal algorithm estimates it should. It has negotiated repeatedly with the same appraisers, attorneys, inspectors, and title companies, which shortens the distance between accepted offer and closing table. In a market as boundary-sensitive as Roslyn, where two homes a quarter mile apart can sit in different villages and different districts, that repetition is the entire advantage.

What volume does not do is guarantee anything. It does not promise a price, a timeline, or a buyer. Any agent who converts a production statistic into a promise about your outcome has stopped describing evidence and started selling. The correct use of a market-share figure is narrow and useful: it tells you how much recent, relevant, local repetition a team is bringing to your specific transaction. Then you check the rest, which is process, communication, marketing, and whether the pricing logic they show you holds up.

What Should You Ask Any Agent to Verify a Market-Share Claim?

Five questions. They take under two minutes and they work on anyone.

A sixth question is worth adding for sellers specifically: what is your sold ratio, meaning what percentage of the listings you took in the last twelve months actually closed. It is the single most seller-relevant statistic in real estate and it is almost never volunteered.

What Is The Scout Residential Team’s Verified Record?

Applying our own framework to ourselves, here is what we claim, what each claim measures, and where it can be checked. RealTrends is an independent rankings organization that verifies submitted production before publishing a ranking, which is why we lead with it rather than with a number of our own construction.

Compiled July 2026. The #2 Long Island, #8 New York State, and #177 nationwide rankings are attributed to RealTrends Verified as published on the team’s Compass agent profiles at compass.com. Volume figures are team-reported and pending client confirmation where flagged above.

Two contextual notes, because they belong in an honest explainer. First, RealTrends sorts teams into size categories and ranks them inside those categories, so a Large Teams by Volume placement is a comparison against teams of similar size rather than against solo agents or mega teams. That is the correct comparison set, and it is worth stating rather than burying. Second, a national ranking and a local ranking answer different questions. The national number establishes scale. The Roslyn number establishes relevance. For a Roslyn seller, the second one is the one that matters.

What Is the Roslyn and East Hills Market Actually Doing?

Market share is meaningless without the market. The table below is the county-level picture from the source of record, the OneKey MLS Local Market Update for Nassau County. It is deliberately restricted to figures that can be checked against a published report, because a market-share page that quotes unverifiable numbers has argued against itself.

Nassau County figures from the OneKey MLS Local Market Update for Nassau County, June 2026, current as of July 8, 2026. Source reports are published in the OneKey MLS market statistics library. Median sale prices do not account for sale concessions or downpayment assistance.

Look at the spread inside a single county in a single month. In June 2026 the Nassau County single family median was $875,000, the condominium median was $922,500, and the co-op median was $379,000. Same county, same month, three answers separated by more than a factor of two, entirely because of which property types the filter allowed through. Now apply that same sensitivity to geography rather than property type. A Roslyn figure filtered to the incorporated village, a Roslyn figure filtered to the 11576 ZIP code, and a Roslyn figure filtered to the Roslyn Union Free School District are three different datasets drawn from three different maps. None of them is wrong. They are answers to different questions, and the same is true of every market-share claim built on top of them.

Sample size compounds the problem at the village level. All of Nassau County, a county of more than 1.3 million people, recorded 51 condominium closings and 63 co-op closings in June 2026. A single incorporated village inside that county will often produce a handful of closings in a month, and a single unusual sale can move a village median by hundreds of thousands of dollars. That is why the closing count belongs next to every median you are shown, and why a village-level median quoted without its underlying count is decoration rather than data. It is also why we publish county figures from the MLS report and pull village figures on request rather than the other way around.

One structural note on the area itself. Roslyn station sits on the Long Island Rail Road Oyster Bay Branch, at Station Plaza on Lincoln Avenue and Railroad Avenue, and it is physically located in Roslyn Heights rather than inside the incorporated Village of Roslyn, which is one more reminder of how loosely the name Roslyn travels. Westbound service runs toward Jamaica, Long Island City, and Penn Station, with connections at Jamaica for Grand Central Madison. The branch is electrified only between Mineola and East Williston, so trains serving Roslyn run on diesel, a scheduling fact rather than a marketing detail. Commute access is one of the few genuinely comparable variables across these villages, and it is worth checking against the current published timetable rather than a general estimate, since branch schedules change seasonally.
