Rare mixed-use investment opportunity on a major arterial in Cambridge. 121 Hespeler Road is a purpose-built, full brick, two-storey property offering an ideal blend of residential income and commercial flexibility. The building consists of three one-bedroom residential apartments, one two-bedroom residential apartment, and a ground-floor commercial unit suitable for office or retail use, with the potential to be converted into a one-bedroom residential unit, subject to approvals. This configuration makes the property particularly attractive for an owner-occupant seeking to operate a business while earning rental income, or for investors looking to enhance residential density. The commercial unit will be vacant on possession, providing an excellent opportunity for professionals, retailers, service-based businesses, or investors seeking a live-work configuration or residential conversion. The space benefits from strong exposure along Hespeler Road and is well suited for a variety of commercial uses. Residential units are accessed through separate common entrances at both the front and rear of the building. The property has been well maintained by the current owner and features durable full brick construction, updated building systems, and vinyl double-pane windows. The building includes ten on-site parking spaces, offering excellent functionality for both residential and commercial occupants. Current residential rents provide stable in-place income with clear opportunity for future optimization, while the vacant commercial unit presents additional income or conversion potential. Dual zoning (C2 Commercial and RM4 Residential) supports continued mixed-use operation and enhances long-term flexibility. Whether for an investor seeking diversified income or an owner-occupant looking to offset business occupancy costs with residential rental revenue, 121 Hespeler Road represents a compelling and versatile opportunity in a high-visibility Cambridge location.
