Brokerage backed by building-level market intelligence.
The Roebling Team at Compass advises buyers and sellers on high-value Manhattan residential and mixed-use transactions — brokerage backed by building-level market intelligence.
The practice is built on original research: sales, valuation, management, and regulatory analysis across 3,315 buildings in Manhattan, Brooklyn and Queens, drawn from a warehouse of 580,000+ recorded transactions and a per-building library of pricing, board governance, financials, and Local Law exposure. Every representation is underwritten from that record.
For buyers, that means pricing framed against the real comparable set and diligence completed before the offer. For sellers, it means positioning tied to a building’s own transaction history, controlled exposure, and a strategy calibrated to the buyer pool the property will actually draw. Backed by Compass’ platform, pre-market inventory, and national network.
Corey Cohen.
As Principal of The Roebling Team at Compass, Corey Cohen advises buyers and sellers across New York City on valuation, pricing strategy, negotiation and complex deal execution. He is also the publisher of The Roebling Index, a real estate research and data platform covering New York City buildings, transactions and market conditions.
Over more than thirteen years in the New York market, Corey has completed 325 transactions representing more than $400 million in volume. His residential practice centers on Manhattan’s cooperative and condominium market, including Park Avenue, Fifth Avenue, Central Park West, Central Park South, the Upper East Side, Upper West Side, Tribeca and West Chelsea.
Corey’s work is grounded in building-level analysis. Comparable sales, apartment condition and timing are only part of the valuation. Property-tax schedules, carrying costs, building finances, regulatory obligations and future marketability can materially affect both what an apartment is worth and how it should be positioned.
He developed The Roebling Index to examine those issues systematically. The platform draws on more than 580,000 recorded transactions across Manhattan, Brooklyn and Queens, including more than 370,000 sales meeting the Index’s published eligibility standards. Its research includes borough, neighborhood and corridor price measurements; thousands of public building profiles; transaction histories; regulatory research; and structured diligence tools for buyers and sellers.
The research exists to serve the brokerage. Corey uses the same building records, comparable-sale analysis and ownership-cost framework to advise clients. For buyers, that means evaluating the apartment, the building and the future cost of ownership. For sellers, it means anticipating how buyers will assess the property and using that analysis to inform pricing, presentation and negotiation.
Corey also publishes The Roebling Report, an analytical column covering New York City housing, market structure, building governance, property taxes and the technical realities of cooperative and condominium transactions. He created Roebling Valuation and a suite of public tools addressing carrying costs, co-op affordability, financial statements and building regulation.
The Roebling Team operates at Compass as a focused advisory practice supported by Compass’s technology, national network and market reach. Corey is a Licensed Associate Real Estate Broker based at Compass’s Upper West Side office.
He is the author of two books on the New York residential real estate market — Unlocking NYC Real Estate: A Comprehensive Guide to Buying Homes in the Big Apple and Unlocking NYC Real Estate: A Comprehensive Guide to Selling Homes in the Big Apple — both practical, structured guides for Manhattan buyers and sellers working through the cooperative, condominium, and townhouse market, published on Amazon.
Within Compass’ platform, the team operates with a focused, boutique structure — allowing for a more deliberate approach to how each asset is positioned, presented, and brought to market. This balance enables institutional-level reach without losing the flexibility required to tailor strategy to the specifics of a property and its buyer pool.
Compass’ platform supports this process through real-time market data, dynamic pricing analysis, and targeted distribution — allowing buyers to track opportunities before they fully surface, and sellers to control exposure and optimize launch timing.
For buyers, this translates into disciplined underwriting and the ability to identify mispricing. For sellers, it means precise positioning, controlled exposure, and a strategy designed to attract qualified demand without compromising leverage.
His role is to protect positioning, enforce pricing discipline, and deliver outcomes that hold up under scrutiny.
Trusted by buyers, sellers, and investors navigating some of New York’s most complex transactions.
“Their targeted marketing strategy yielded two competitive offers within two weeks of listing. From contract signing to closing, Corey stayed in close contact and shepherded us every step of the way.”
“I thought: I don't need another broker to send me listings I'm already seeing online. And then I met Corey. He stuck by our side through a search for a diamond in the rough and guided us through an extremely difficult negotiation. Corey is much more than a broker — he is an advisor.”
“We had a long, hard slog of a house hunt — three boroughs, two states, nearly a year. We saw brokers from the big, well-known NYC agencies. Corey really stood out. He's not afraid to give his honest opinion: he'll tell you when the price is too high, even though it costs him a commission. When you've been looking as long as we were, you realize how rare that is. We got a great deal on the property we eventually settled on — at the low end, possibly even slightly below market value.”
“I'm a very picky buyer. I needed a specific building with specific zoning, and as an out-of-area buyer, I was navigating neighborhoods and lease language I didn't fully understand. After several deals that almost came together — and a few that just fell through — Corey landed exactly what I wanted and negotiated a better deal than expected.”
“Corey brought deep insight into the NYC market and remained highly engaged from our very first conversation through closing. He made what can be a stressful process feel smooth and seamless — we always felt informed, supported, and confident at every step.”
“Corey Cohen showed great initiative — providing timely research on properties, education on the process, and recommended reliable professional resources. He responded personably and quickly to every question. An excellent experience from start to finish.”
“We started looking in December 2020, peak of Covid. Corey helped us navigate and evaluate 25+ apartments across the Upper East and West Side, arming us with research and expertise at every step. After we had an accepted offer, he guided us strategically through the co-op application and closing. We couldn't have done it without him.”
“Corey's knowledge of the co-op process — which can be especially confusing for a first-time buyer — was invaluable. My transaction ended up being longer than expected, but his patience and constant reassurance made a stressful process much more manageable.”
