54 Old Main Street, South Yarmouth offers a rare opportunity to acquire zoning and location leverage at a basis that would be extremely difficult to replicate along the Route 28 commercial corridor. Located at the intersection of Old Main Street and Forest Road, just one block off Route 28, the property captures the traffic, visibility, and economic gravity of the corridor without incurring Route 28 pricing or constraints. The ±24,393 SF parcel is improved with a ±2,250+ SF mixed-use building configured as both residential and commercial space under B1 zoning. The residential component includes a 2-bedroom, 1-bath living area with full kitchen, laundry, cathedral-ceiling family room, and storage. The commercial component features a separate retail entrance, reception area, two finished office/storage rooms, and a half bath—supported by basement, attic, and garage storage. This is not a trophy asset—it is embedded optionality: operate a business, combine live/work, lease one component, or reposition the asset over time. In a market where new small-scale commercial approvals are increasingly difficult, this property represents a strategic control position in one of Mid-Cape’s most durable commercial zones.
