39 Pineway Avenue 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.
