Plexes for sale · Montreal · Centris 2016-2026
The number of plexes for sale in Montreal at each month-end, and the number of new listings, year by year since 2016: the peak, the frenzy trough, the absorption rate, months of inventory, and the comparison with single-family houses and condos in the same city. Centris figures, not estimates.
In Montreal, an average of 1,806 plexes (2 to 5 unit buildings) were for sale on Centris at each month-end in 2026 (January to September), against 2,130 in 2016: plex inventory is 85% of what it was ten years ago, a milder decline than in most of the 23 cities tracked (median 58%). The trough was 2020 (1,148 plexes, -46% from the 2016 peak); since then, inventory has climbed back 57%. The result in 2026: 7.7 months of inventory for plexes (buyer's market) against 5.0 for single-family houses (balanced market) and 7.6 for condos. Plexes sell 2.7 months more slowly than houses in Montreal: an income-property buyer has time to run the numbers, and the seller must list at the price the rents justify.

What it changes when selling or buying a plex in Montreal
At 7.7 months of inventory, the plex in Montreal is a buyer's market in 2026: there are more buildings for sale than investors ready to pay the asking price, and a plex listed at its 2022 multiplier stays listed. For a seller, the entry price is everything: buyers compare 1,806 buildings, divide the price by the rents, subtract taxes and the mortgage at today's rate, and move on to the next one. For a buyer, this is the time to visit the units, ask for the leases and the statements, and negotiate on the numbers rather than on emotion. Houses, meanwhile, remain at 5.0 months: a plex is an investment and sells like one, on the numbers, taking the time it takes. The sector's price per unit and multiplier are in plex prices in Montreal.
How to read these figures
One count per year for all of Montreal: what gets listed (flow), what is for sale (stock, month-end average) and what sells, for plexes only. All three come from Centris, brokers' listings; private sales, frequent for small buildings, are not included. Stock is the measure that explains price: when it climbs, each investor has more choice and negotiates on the multiplier. The pages plex prices in Montreal and price per unit in Montreal read the same buildings from the price and income side.

Do plexes sell more slowly than houses in Montreal?
Yes, clearly: 7.7 months of inventory for plexes against 5.0 for houses in 2026. A plex is bought on its numbers: the buyer waits for the leases, the tax statements and the financing, and a building listed above what the rents justify stays listed; a house is bought to live in, by far more buyers.
