About 139 Main Street
Main Street presence in Seeley's Bay - and it's a good one. This is a well-known retail space that's been a fixture in the community, sitting on just over an acre, 2 mins from Highway 15 with way more potential than just the storefront. The building itself is concrete block with a steel roof and inside you've got a slab on grade retail floor, private office, break room, washroom, and plenty of storage. The land is where things get interesting. Over an acre gives you real room to grow - think outdoor storage, severance or future development. Multiple income streams are very much on the table here.
