**A Rare Multi-Parcel Investment & Development Opportunity**
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 evolved into a remarkable nine-parcel assemblage in the heart of the Ronkonkoma/Nesconset corridor.
There are currently 8 parcels available, presenting a rare opportunity to acquire a substantial mixed-use real estate portfolio with exceptional flexibility and long-term potential.
More than just real estate, this is an opportunity to shape the future of a strategically positioned collection of properties. Whether your vision includes a thoughtfully planned residential community, commercial investment, a combination of residential and commercial uses, or a phased development strategy, the remaining assemblage provides a foundation that would be extraordinarily difficult to recreate in today's market.
Lot Breakdown:
Two commercially zoned parcels** with prominent frontage and visibility along Smithtown Boulevard.
Five residential development parcels** totaling approximately 2.75 acres, offering potential for future residential expansion.
A single-family residence** that may serve as a rental property, private residence, or future redevelopment component, subject to applicable approvals.
What makes this offering truly exceptional is not simply the acreage—it's the opportunity. Acquiring multiple adjoining properties under one ownership reduces the time, uncertainty, and expense typically associated with assembling individual parcels from separate 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 properties enjoy excellent visibility and proximity to Lake Ronkonkoma, the Long Island Rail Road, shopping, dining, major transportation corridors, and regional employment centers.
Few opportunities offer this combination of location, commercial frontage, existing residential improvements, vacant land, and long-term development potential within a single offering.
For more than seven decades, these properties have been part of one family's story. Today, the remaining assemblage is ready to become part of someone else's vision.
*Parcel 3, containing the five-unit multifamily property, is currently pending sale and is excluded from the remaining assemblage offering. 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.*
