What it changes when buying or selling a plex in La Prairie
At 1.05 times the price of a house, a plex in La Prairie is still a yield purchase: the gap with houses is thin, rents cover a serious share of the mortgage, and an owner-occupant gets a home for less than a house alone. This is the kind of market where the local investor keeps the edge over the Montreal speculator, because the numbers work without betting on appreciation. To sell, the right price is set by gross revenue and the multiplier, not by square footage.
How to read these figures
One median price per year and per category, for all of La Prairie: plexes on one side, houses and condos on the other, all pulled from Centris the same day. Plex is a broad category (two to five units): in a year when more triplexes than duplexes sell, the median rises without prices having moved. The plex ÷ house ratio corrects part of that effect by comparing two markets in the same city, the same year. For price per unit, which neutralizes building size, see plex prices per unit, 20 cities.
