Marcus & Millichap is pleased to present 640 Montauk Highway (“the Subject Property”), a well-located office asset in the heart of Shirley, NY. Situated on a 1.35-acre parcel, the Subject Property comprises approximately 7,402 square feet of well-maintained office space and is currently 100% occupied. The site offers exceptional functionality, supported by a generous parking ratio of 5.94 spaces per 1,000 square feet—an increasingly valuable feature for medical, professional, and service-oriented tenancy. Positioned along Montauk Highway, one of the area’s primary east–west commercial corridors, the property benefits from strong visibility and seamless connectivity. Tenants and visitors enjoy convenient access to major regional thoroughfares, including William Floyd Parkway (±0.5 mile), Sunrise Highway (±1.0 miles), and the Long Island Expressway (±5.0 miles), providing efficient travel throughout Suffolk County and the broader Long Island region. The property is surrounded by a diverse mix of demand drivers that support long-term occupancy and tenant performance. Nearby anchors include South Port Shopping Center, Floyd Harbor Center, and the Shirley LIRR Station—each contributing to consistent daytime population, consumer activity, and commuter traffic. Local demographics further underscore the strength of the location. More than 51,000 residents live within a three-mile radius, with average household incomes exceeding $127,000, reflecting a stable and economically resilient customer base.
