Description
This outstanding investment opportunity features an approximately 40,000-square-foot professional office building situated on 1.19 acres in the center of East Patchogue, with prime frontage along the heavily traveled East Main Street (Montauk Highway). The well-kept two-story building houses a combination of professional and medical office suites, supported by strong leases and low operating costs. Most tenants operate under Modified Gross leases, contributing their proportional share of taxes and utilities, which promotes steady cash flow and efficient expense management. In 2023, five new rooftop HVAC units were installed, improving reliability and minimizing future capital outlays. The property is currently 95% leased, with only one vacancy, and existing lease terms range from three to five years, with extension options that provide long-term stability and growth potential. Although presently self-managed, new ownership could further enhance efficiency by implementing professional property management. With possible owner financing available, this asset represents a rare combination of location, occupancy strength, and operational ease—making it an attractive opportunity for investors targeting a high-quality office property along a key Long Island corridor.
