For whom: the family or the investor
The house, for the family that wants its lot and no tenant: in Montreal, it sells faster than the plex and closer to the asking price, which means less room to negotiate when buying, and a simpler resale. The plex, for whoever accepts a tenant upstairs or downstairs in exchange for a rent that pays part of the mortgage, and for the investor who counts in price per door: $420,000 against $755,000 for the house. An owner-occupied plex is bought with 5% down up to $500,000 (duplex) or 10% (triplex, quadruplex); without living in it, 20%. The trade-off is management, the Tribunal administratif du logement and leases that set the income: the median says nothing about those of the building you are looking at. The complete file is in investing in a plex in Montreal in 2026, and the house alone in home prices in Montreal 2016-2026.
How to read these figures
Days on market is the number of days between listing and the accepted offer, in median. The sold-to-asking ratio compares the sale price with the last listed price: below 100%, the buyer negotiated; above, there was a bidding war. Ten-year changes compare 2016 with 2026 (January to September); the Montreal plex is tracked because at least 20 sell a year.
