Nestled in the quaint and serene community of Mastic Beach, this expansive single-family residence offers exceptional space, versatility, and untapped potential, set on a generous .89-acre parcel. The main level boasts five well-proportioned bedrooms, two full bathrooms, a comfortable living room, and a separate family room, providing an ideal layout for both everyday living and entertaining. This unique property features two distinct basements—a primary basement within the home and an additional basement with its own separate entrance—offering incredible flexibility for extended living, recreation, or supplemental space. An unfinished attic, accessible via a private entrance from the garage, presents a rare opportunity for customization and future expansion. Completing this offering is a two-car garage positioned to the right of the home (not reflected on the floor plan), along with expansive outdoor grounds, making this a truly exceptional property with endless possibilities.
