Island Associates Real Estate

Island Associates Real Estate is a Commercial Real Estate Agent in Smithtown, NY. Established in 1991, the firm provides full-service commercial brokerage services across New York and Florida. It represents national brands and local owners in buying, selling, leasing, and managing commercial property. The company serves the East Coast business community, with a specific presence in Long Island, the Tri-State area, and Southeast Florida.

The brokerage was founded by Roger Delisle, who began his career in commercial real estate after working with his father, a real estate attorney. Delisle’s first transaction involved selling a roller rink in West Babylon to make way for a drug store, an experience that introduced him to buildout costs and square-foot pricing. The firm emphasizes its familiarity with local zoning and its experience in property management, development, dispositions, and marketing. A key differentiator is the use of in-house legal counsel, which allows contracts and documents to be prepared and reviewed internally, reducing hand-offs and streamlining the transaction process. Services include strategic representation for sales and purchases, landlord and tenant leasing for retail, office, industrial, and mixed-use spaces, investment underwriting, 1031 exchange guidance, tenant representation, and hands-on property management.

The headquarters is located at 444 Route 111, Suite 1, in Smithtown. The office occupies a former IRS building on this busy corridor. The firm holds a rating of 3.70 based on customer reviews.

Island Associates Real Estate combines deep local zoning expertise with in-house legal support to manage commercial transactions end-to-end for clients in Smithtown and across the East Coast.
