About this home

For the first time in more than 75 years, a legacy of land assembled over generations is being offered to the public. Beginning with the acquisition of its first parcel in 1949, what started as a single investment has evolved into a remarkable nine-parcel assemblage encompassing approximately 4.21 acres in the heart of the Ronkonkoma/Nesconset corridor. Never before offered as one acquisition, this is a once-in-a-generation opportunity to control an entire mixed-use portfolio with exceptional flexibility and long-term potential. More than just real estate, this is the opportunity to shape the future of an entire development block. Whether your vision is a thoughtfully planned residential community, a mixed-use redevelopment, an income-producing investment portfolio, or a phased development strategy, this offering provides a foundation that would be extraordinarily difficult to recreate in today's market. The assemblage includes: • Two commercially zoned parcels with prominent frontage and visibility along Smithtown Boulevard. • A six-unit multifamily property providing immediate income while future plans are developed. • Five contiguous residential development parcels totaling approximately 2.75 acres, offering exceptional potential for future residential expansion. • A single-family residence that may serve as rental property, or future redevelopment component. What makes this offering truly exceptional is not simply the acreage—it's the opportunity. Acquiring nearly an entire development block under one ownership eliminates the time, uncertainty, and expense of assembling multiple properties from different owners. It creates a level of flexibility and control that is increasingly difficult to find in today's market. Strategically positioned with frontage on Smithtown Boulevard and additional access from Spectacle Lake Drive and Lillian Drive, the property enjoys outstanding visibility, multiple access points, proximity to Lake Ronkonkoma, the Long Island Rail Road, shopping, dining, major transportation corridors, and regional employment centers. Very few opportunities offer this combination of location, existing income, commercial frontage, residential development potential, and long-term flexibility within a single acquisition. For more than seven decades, this property has been part of one family's story. Today, it is ready to become part of someone else's vision. All information is deemed reliable but not guaranteed. Buyers are responsible for independently verifying zoning, permitted uses, development potential, approvals, utilities, lot dimensions, environmental conditions, and all other matters material to their intended use.
