A rare opportunity to become the next steward of an exceptional home or investment property in one of Southborough's most convenient locations. Set on an oversized 1.4-acre lot along a quiet neighborhood street, this versatile five bedroom, three and a half bath property (2,586 sq. ft. total) offers two attached living spaces — a four bedroom + office, two and a half bath main residence (approx. 2,078 sq. ft.) and a one bedroom, one bath in-law suite/ADU (approx. 508 sq. ft.). The configuration is nicely suited for multi-generational living, an au pair suite, income property potential, or whatever flexible arrangement fits your plans. The main residence offers a traditional floor plan with an eat-in kitchen with stainless steel appliances, dedicated first floor laundry room/pantry, a large formal dining room, separate family and living rooms, a primary suite with attached ensuite bath, three additional generously sized bedrooms with hardwood floors sharing a full hall bath with double vanity, and a bonus room perfect as home office, gym, or flex space of your choosing. The in-law unit includes an eat-in kitchenette, living room, bedroom, and full bath with tub. Outside, a composite deck overlooks the in-ground pool (in good working order), and the expansive lot leaves plenty of room to garden, play, entertain, or simply spread out. With this much space, land, and flexibility in a convenient Southborough location, there is significant upside for the right buyer ready to bring their vision to life. Ideally located with proximity and access to top-ranked schools and easy access to the Commuter Rail, Rt. 9, 495, and the Mass Pike.
