ABS Partners Real Estate

What ABS Partners Real Estate does

ABS Partners Real Estate is a privately held, full-service commercial real estate firm headquartered in New York City, operating under the legal name ABS Partners – Real Estate, LLLC. Founded around 1997 by Peter Burack, Gregg L. Schenker, Steven Hornstock, and Chairman Earle S. Altman, the firm has grown to over 250 employees and operates across the New York metropolitan area with select national exposure. Its service platform spans landlord representation, tenant representation, retail leasing, investment sales, property management, construction management, appraisal, marketing and research, and a dedicated Special Situations team for distressed and transitional assets. Capital markets advisory is delivered through the ABS Altman Warwick joint venture, covering debt, mezzanine, construction financing, and proprietary joint venture equity.

The firm serves property owners, corporate tenants, retail occupiers, and real estate investors, generating revenue from a mix of transaction-based brokerage commissions, recurring property management fees, project-based construction management fees, and professional services fees for advisory and appraisal work. ABS Partners also holds and manages a portfolio of core NYC commercial properties (including 222 Park Avenue South and 915 Broadway) and in 2025 acquired a 75-year ground lease at 515 West 57th Street with plans for ~400 residential units, signaling a tilt toward principal ownership and redevelopment alongside its fee-based services. Its go-to-market is relationship-driven, direct-to-client field sales supplemented by an inside sales team, a website listings portal, an investor portal, and a thought-leadership platform anchored by quarterly NYC CRE Snapshot market reports published since 2020.

Underlying technology is conventional CRE stack: the firm uses Workspeed for tenant operations and operates no disclosed proprietary AI/ML, data, or platform products; competitive differentiation stems from headcount tenure ("hundreds of years of combined experience"), the breadth of in-house service lines, third-party relationships with lenders/attorneys/accountants, and incumbency in the NYC market (recognized as a 2025 CoStar Power Broker Award winner in both Landlord and Tenant Representation).
