Sixplexes and Five-Unit Buildings for Sale in Ottawa

Why five and six units change the game
At five units, a building moves from residential to commercial lending, and that opens the door to CMHC multi-unit insured financing. Programs such as MLI Select can offer higher loan-to-value and longer amortizations than conventional loans, which can change the cash flow of a purchase considerably.
Sixplexes also spread risk: one vacancy is a sixth of the income. They are still small enough for a hands-on owner, and large enough to justify professional management as a portfolio grows.

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.
