This exceptional opportunity presents a ±40,000 square foot professional office building located on 1.9 acres in the heart of East Patchogue, prominently positioned along the highly trafficked East Main Street (Montauk Highway). The two-story property is well maintained and features a mix of professional and medical office suites, with strong lease agreements in place and minimal operating expenses. Most tenants occupy under Modified Gross lease structures, contributing proportionate shares of taxes and utilities, ensuring predictable cash flow and operational efficiency. In 2023, five brand-new rooftop HVAC systems were installed, further enhancing the building’s reliability and reducing future capital expenditures. The property is currently 95% occupied, with only one vacant unit, and all existing leases range from three to five years. Tenants are satisfied and have options to extend, providing long-term stability and upside potential. While the building is currently self-managed, there is an opportunity to streamline operations and reduce maintenance overhead by engaging professional property management services. Possible owner financing. This asset offers a compelling blend of location, tenancy, and operational simplicity—ideal for investors seeking a high-performing office property in a prime Long Island corridor.
