6 to 12 Unit Apartment Buildings for Sale in Ottawa
Ottawa 6 to 12 unit buildings
Scale that works for serious investors
Buildings of six to twelve units combine meaningful income with manageable risk. They are financed as commercial properties and are eligible for CMHC multi-unit insured financing, including MLI Select, which can offer higher loan-to-value and longer amortizations than conventional loans.
Each extra unit spreads fixed costs and vacancy risk further: one vacancy in a twelve-unit building is less than a tenth of the income. Buildings in this range justify professional management and are a common step toward larger apartment buildings.

Market context
Ottawa rental market today
Ottawa's rental vacancy rate rose to 3% in 2025, according to CMHC, as record rental construction added supply. Near-term rent growth is expected to be more modest, with slower population growth and federal job reductions weighing on demand (Marcus & Millichap).
For buyers, that means underwriting on today's actual rents and realistic vacancy rather than last year's rent growth. Over the long term, Ottawa's stable institutional economy continues to support rental demand.
MLI Select terms are set by CMHC and change from time to time. See the current CMHC MLI Select summary, and confirm details with your lender.
