Brokerage informed by original research.
I'm the Founder and Principal of The Roebling Team at Compass and 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 New York real estate, my work has centered on valuation, pricing strategy, negotiation and complex deal execution. I advise buyers and sellers across the city, with a particular focus on Manhattan's cooperative and condominium market along Park Avenue, Fifth Avenue, Central Park West, Central Park South, the Upper East Side, Upper West Side, Tribeca and West Chelsea.
New York apartments cannot be evaluated from a listing page alone. Property taxes, building finances, regulation, comparable sales, assessments and future carrying costs can materially affect what an apartment is worth and how it should be positioned.
Over that time I've represented buyers, sellers, landlords and investors across residential and mixed-use transactions, authored two guides to buying and selling New York real estate, and built public tools addressing carrying costs, co-op affordability, financial statements and building regulation. The Roebling Team operates at Compass, which gives the practice broad resources and market reach while preserving direct attention to the strategy and execution of each transaction.
Volume and transaction count are Corey’s personal production across residential sales, residential leasing and commercial leasing, as of September 2026. Roebling Index research figures appear below.
Research built for real decisions.
I created the Roebling Index to examine the market at the building level. Its research draws on more than 580,000 recorded transactions, including more than 370,000 sales meeting the Index's published eligibility standards.
The platform includes market indices, public building profiles, transaction histories, regulatory research and structured diligence tools. Its purpose is to distinguish broad market narratives from what is actually happening within a particular building, neighborhood or ownership structure.
The research exists to serve the brokerage. For buyers, that means evaluating the apartment, the building and the future cost of ownership — not merely the asking price. For sellers, it means anticipating how buyers will assess the property and using that analysis to inform pricing, presentation and negotiation.
How I work with sellers and buyers.
Pricing grounded in the building, not just the block.
An effective pricing strategy requires more than identifying the nearest comparable sale. I examine differences in condition, line, floor, exposure, building economics and transaction timing to determine where a property should sit in the current market.
The research also helps identify issues buyers are likely to raise — including property taxes, assessments, capital projects and regulatory obligations — before those issues begin controlling the negotiation.
The purchase price is only part of the economics.
The purchase price is only one part of an apartment's economics. I help buyers evaluate comparable sales, carrying costs, property-tax schedules, building finances and potential resale position.
That work becomes particularly important in buildings with expiring tax benefits, unusual land or ownership structures, substantial capital obligations or limited comparable inventory.
