57 S Main St, Middletown, CT 06457

This medical office campus includes properties at 51 and 57 South Main Street and is being offered for sale with 6,618 square feet available for occupancy at the time of sale. The campus is described as meticulously maintained by the current owner, who previously operated an ENT practice there for decades. Ownership includes shared amenities and infrastructure upgrades, with a lone medical tenant on a landlord-friendly triple net lease that shifts a portion of maintenance, property tax, and insurance responsibility away from the owner.

The properties sit directly across the street from Middlesex Hospital’s main campus, providing convenient, walkable proximity for healthcare users and staff. A shared 30+ car parking area was freshly paved and striped in 2025. Additional reported capital improvements include new hydraulics installed in the elevator serving 57 South Main in 2025, a chimney redo and partial roof replacement at 51 South Main approximately five years ago, and HVAC unit replacements at 57 South Main also approximately five years ago. Financials and interior photos are available upon request.

For a buyer or incoming tenant, the available occupancy at sale supports a new medical practice and/or additional tenanting while maintaining an existing triple net income component. The 57 South Main basement area of 1,772 square feet is described as convertible to paid storage for tenants or possibly additional leasable space, supporting flexible use depending on operational needs.
