331 Main Street CHARMING HISTORIC DISTRICT HOME WITH GUEST HOUSE, JUST THREE BLOCKS FROM THE BEACH! Picture this: coffee on the screened porch, a stroll to the beach and marina, then an afternoon by your own in-ground pool. This Bay St. Louis gem pairs a 2, 260 sq. ft. main home with a charming 1, 208 sq. ft. guest house, for 5 bedrooms, 4 full baths, a sunroom and plenty of room to spread out. The lot stretches from Main St. through to State St., and the guest house has its own separate entrance and parking on the State St. side, so guests come and go without disturbing the main home. It's a natural family compound: room for in-laws, adult children, or visiting family, with everyone close but still private. The guest house also has strong Airbnb/VRBO potential. Visitors love staying in walkable Old Town near the beach, restaurants, shops and festivals. Private patios, lush gardens and small-town coastal charm complete the picture. Homes like this rarely come along, so schedule your showing today!
