Plexes in Greater Montreal: Inventory Up 25% While the Median Price Stalls

The plex has long been Greater Montreal's tightest segment. The QPAREB's October 2026 figures show a change of pace: it is now the property type with the fastest-growing inventory, and its median price is no longer rising. Here are the numbers, an inconsistency in the release worth knowing, and what it changes for investors.

What the QPAREB says about plexes in October

• Inventory: active plex listings are up 25% year over year according to the release highlights, the largest increase of the three property types.
• Median price: flat year over year in the Montreal CMA.
• Average selling time: 46 days, versus 36 for a single-family home and 56 for a condo.

Charles Brant, director of the QPAREB's Market Analysis Department, sums it up: while plex inventory grew 28% year over year, median price growth has been less sustained since August.

25% or 28%: an inconsistency to flag

The same release gives two values for the plex inventory increase: 25% in the highlights and 28% in Charles Brant's quote. We do not know which is correct, or whether they measure different things. The conclusion does not change: plex supply is growing faster than the other types.

A local benchmark: Rosemont–La Petite-Patrie

Centris quarterly statistics for Rosemont–La Petite-Patrie, one of the island's most active plex neighbourhoods, point the same way for Q3 2026:

• Sales: 65 plexes sold, down 24% year over year.
• Median price: $950,000, up 1%.
• Active listings: 140, up 9%.
• Average selling time: 39 days.

Fewer sales, a little more supply and a price that barely moves: in an already expensive central neighbourhood, the levelling off of the median price is clear.

Why a median price stalls when supply rises

When inventory grows faster than sales, buyers compare more and sellers can no longer price on scarcity alone. Price growth stops before prices fall, which is exactly what October shows for plexes in the CMA.

For investors, the question shifts. In a shortage, you bought a plex because it was available. With more choice, you can be selective again about what drives a rental building's value: in-place rents and their gap to market, unit condition, upcoming work. Our guide to plex return on investment covers those parameters.

What it changes in practice

• Investor buyers: more plexes to compare and enough time to review leases and inspect. Negotiation is won on documented defects, not on a market drop that hasn't happened.
• Owners selling: competition is stronger than in spring. A price backed by recent comparable sales in your area, and documented income, matter more than ever.
• What to watch: if inventory keeps growing at this pace, the next few months will show whether the flat median price holds or gives way.
