Solil Management is a family-owned real estate investment firm headquartered in New York City with over 80 years of experience in owning and managing residential and commercial properties. The company was founded by Sol Goldman, one of New York's most prolific investors and real estate owners. The firm's investment strategy centers on long-term ownership. This approach has enabled the company to assemble a portfolio that includes the land beneath the Gramercy Park Hotel, a 17% stake in the World Trade Center development in lower Manhattan, and properties in Midtown Manhattan including sites housing Olympic Tower and the Cartier Mansion. The portfolio spans multiple boroughs across New York City, with the heaviest concentration in Manhattan, followed by Queens and Brooklyn. Solil Management operates as a vertically integrated owner-operator, directly managing its own properties rather than outsourcing to third-party management firms. The portfolio includes office buildings, mixed-use properties, and retail assets, as well as with high-end residential apartments on the Upper East Side, and other prime locations. Recent transaction activity includes the sale of 37 East 60 Street to Extell Development for $103.3 million in February 2025 and the disposition of 166-14 Jamaica Avenue for $2.5 million in November 2025. The company maintains a lean organizational structure with property management, leasing, and financial operations centralized at its Midtown Manhattan headquarters.
