SL Green is a self-managed REIT and the largest owner of office real estate in Manhattan. The company owns interests in 26 office properties totaling roughly 23.4M square feet, concentrated in prime Midtown locations around Grand Central, Park Avenue, and Sixth Avenue, with flagship assets including One Vanderbilt and One Madison Avenue. SL Green's core tenants are large commercial users — financial services firms, law firms, tech companies, and professional services businesses — who sign multi-year leases typically running 7–15 years, paying base rent plus pro-rata increases in operating expenses and real estate taxes. Beyond rental income, SL Green runs several adjacent businesses: a debt and preferred equity (DPE) investment platform that originates and acquires subordinate credit positions on NYC commercial real estate; SUMMIT One Vanderbilt, an observation deck and immersive art experience that drew roughly 2.2M visitors in 2025 and is expanding to Paris; and Green Loan Services, the largest active special servicer of single-asset, single-borrower loans in the U.S. SL Green's business model centers on acquiring, repositioning, leasing up, and then selling or joint-venturing properties to harvest embedded equity — management treats disposition gains as recurring cash flow, not one-time items. The company is growing by pushing occupancy toward 95%, reducing tenant concessions, expanding its opportunistic debt fund platform, and pursuing a large-scale Midtown development site.
