Who Argo Real Estate is
Argo Real Estate is a New York City real estate firm founded in 1952 by Henry Moskowitz, who in the early 1950s began acquiring and managing Upper West Side rental buildings, many of which were later converted to cooperative ownership. The firm is now led by Mark Moskowitz, the founder's son, as President and CEO, and describes itself as an independent, family-led company.
Argo is worth understanding as a dual-role firm. It is both an owner/operator — it owns and operates buildings in its own portfolio — and a third-party managing agent that manages co-ops and condominiums for outside boards. For a buyer or seller, that distinction matters: whether Argo simply manages a building on a board's behalf, or has an ownership or sponsor interest, changes who is across the table. The firm also operates an affiliated residential brokerage and lists development and project-management services.
One point of clarification specific to our records. In several of our building files, Argo Real Estate appears in a development or conversion-sponsor capacity rather than as the ongoing managing agent — for example, in connection with condominium conversions where Argo acted as sponsor. A sponsor role is a development function and is not the same as third-party building management; the two should not be conflated. We only list a building under Argo's management below when we can confirm Argo is the current managing agent of record.
Common diligence questions
These are the questions we ask on a buyer's or seller's behalf when a building is managed by Argo Real Estate. They are prompts for diligence, not claims about this firm's practices — answers vary by building and change over time.
- Owner/operator versus third-party role: Is Argo the third-party managing agent for this specific building, or does it have an ownership, sponsor, or other interest — and how does that affect who negotiates and approves on the building's behalf?
- Board-package turnaround: How long is management currently taking to review a completed purchase application and schedule a board interview, and what is the realistic window from submission to a closing-ready approval?
- Access to financials, reserves, and minutes: What financial statements, current budget, reserve position, and board-meeting minutes will management release to a purchaser's attorney, and how quickly — and how much is available through the firm's building-document portal versus by request?
- Responsiveness and staffing: Which property manager is assigned to the building, and how is on-site staffing structured (resident manager/superintendent, doorman/concierge coverage) versus what is handled off-site at the management office?
- Closing, waiver, and move-in handling: How does the agent process the recognition/waiver of the right of first refusal (co-op) or the waiver of the right of first refusal (condo), closing scheduling, and move-in coordination, including any deposits, fees, and required lead time?
- Assessments and capital projects: Are any current or anticipated capital assessments, Local Law 11/facade, elevator, or mechanical projects on the books, and how are they being funded?
- Flip-tax administration: If the building has a flip tax (transfer fee), how is it calculated and collected at closing, and who is responsible for it under the building's rules?
- Certificate-of-insurance (COI) process: What are the current insurance and COI requirements for shareholders/owners, contractors, and movers, and who must be named as additional insured?
Buying or selling in an Argo Real Estate building?
We publish management-company profiles because the managing agent shapes the parts of a transaction a buyer or seller actually feels — how fast a board package moves, what the financials disclose, and how a closing gets scheduled. The Roebling Team at Compass tracks Manhattan's co-op and condo inventory building by building and brings that context to every deal.
