About 45 Black Diamond Road

RARE 9-Unit residential acreage with full municipal servicesminutes to the 401. Turnkey multi-residential parcels of this scale almost never hit the open market. Situated on a prime 2.74-acre parcel on Black Diamond Road just minutes from the Highway 401 corridor, this exceptional, fully occupied income property has been proudly family-owned and maintained since 1978. Unlike typical rural multi-unit investments, this property is fully connected to municipal water, municipal sewer, and natural gas, eliminating rural well and septic liabilities entirely. The residential setup features nine detached rental homes comprising six 2-bedroom units, two 3-bedroom units, and one 1-bedroom unit. Substantial capital improvements have already been completed across the parcel, including nine separate 100-amp electrical panels and five newer high-efficiency gas furnaces for streamlined utility management. Dual road frontage ensures excellent accessibility, expansive parking, and long-term site flexibility, while two detached garages (a 2.5-car and a separate single-car) provide valuable workshop or storage capacity. Operating overhead is kept low thanks to an established arrangement with a resident tenant who oversees year-round groundskeeping and snow removal. Whether you are expanding an investment portfolio with proven, day-one cash flow or securing an irreplaceable multi-generational family compound, this turnkey holding delivers unbeatable stability, location, and long-term upside. Full financial summary, rent roll, and unit breakdown are available upon request.

works out to roughly $2,856 per square foot. Chat with Zara if you'd like a deeper read on whether this multiplex fits your budget and timing.
