New York City Office Investment
We buy Manhattan office buildings with strong bones and real upside.
Vertex owns five office buildings in Manhattan and Long Island City. Four were acquired since November 2025, representing approximately $460 million of total capitalization. Every building is managed and leased by Olmstead Properties, our exclusive operator.
The Platform
Capital that can close. An operator that can execute.
Vertex Properties is a New York City–based investment platform actively expanding its office portfolio, targeting assets with strong fundamentals and clear repositioning upside.
Olmstead Properties is our exclusive operator. Olmstead manages, leases and co-invests in every building Vertex owns. Separately, and on its own account, Olmstead owns, manages and leases a 4.5 million square foot Manhattan portfolio — which is what gives Vertex an operating engine most buyers of this size do not have. Sellers and brokers deal with one decision-maker, not a committee.
That combination is why the platform has closed four transactions in eight months, including an all-cash purchase and a recapitalization. We underwrite fast, we do not retrade, and we put a full-time operating team behind every building on day one.
Vertex is backed by the Arnow family, whose real estate legacy in New York City dates to the 1930s.
Confirm wording: press coverage describes Vertex as backed by the “Rosenblatt and Arnow families” — the Rosenblatts being the family behind Olmstead Properties, now in its fourth generation. The current site also names Hamlin Ventures as a partner. Tell me which affiliations should appear here.Olmstead Properties

Track Record
Generations of building in New York.
Over multiple generations, the Arnow family has developed more than 10 million square feet of office and residential property across the United States, with a primary focus on New York City. A significant portion of the family’s holdings was sold in 1997; the family continues to own a portfolio of legacy assets.

Your Historical Transactions page lists this as “4301 22nd Street, ~215,000 square foot office building.” You have told me it is ~210,000 SF and currently owned, so I have moved it out of past transactions and into the current portfolio. Confirm the address format and the final square footage.
