Every income property sold on Centris declares its price, its number of units and its potential gross revenue. On 300 sales in Ahuntsic-Cartierville in 12 months, the median price is $931,000 for a median building of 3 units, which gives $355,000 per door. The median plex found a buyer in 18 days. The borough recorded 305 plex sales in 12 months; the 300 read are taken in Centris number order, with no sorting by price or age.
The figure an investor looks at first is the gross rent multiplier, the GRM: the price paid divided by the building's annual gross revenue. In Ahuntsic-Cartierville, it is 18.2x: half the buyers paid less than 18.2 times the annual rents, the other half more. Across the 16 boroughs tracked, it runs from 15.7x (Ville-Marie (downtown)) to 19.2x (Verdun and Nuns' Island); for Montreal as a whole the median is 17.7x, and for the 20 Quebec cities tracked, 15.8x.
Crossing the two medians, a door in Ahuntsic-Cartierville brings in on the order of $19,505 per year, or $1,625 per month. That is an order of magnitude computed on medians, not a guaranteed rent: the actual rent is in the lease.

In Ahuntsic-Cartierville, the triplex costs 29.6% less per door than the duplex: $299,167 versus $425,000. That is the door discount: the land, the roof and the structure are shared, and the owner-occupant pays full price for a duplex door because they are buying a home first.
Across the 16 boroughs, the median price per door goes from $415,500 for a duplex to $303,542 for a triplex, $268,250 for a fourplex and $224,200 for 5 units and more. Selling time stretches with size: 18 days for a duplex, 44 days for 5 units and more.
