- On the year's new listings: 30% of plexes listed in 2016 saw their listing expire the same year, 33% in 2025. One plex in four or more did not find a buyer within the year: the asking price does not hold up against the rents and the rates.

What it changes when selling or buying a plex in Sainte-Thérèse
At 24% failure, Sainte-Thérèse is a city where plexes sell: expired listings are rare, and a building that stays listed signals a price frankly off the market, rents too low for the price or a visible defect. For a seller, the risk is not failing to sell, it is underselling by accepting too fast. For a buyer, waiting for a price cut rarely pays off here, even on a plex. The number of plexes for sale and months of inventory, year by year, are in plexes for sale in Sainte-Thérèse; the same count for houses is in houses that do not sell in Sainte-Thérèse and for condos in condos that do not sell in Sainte-Thérèse.
How to read these figures
Two measures from the same Centris query, same settings: Income property category, whole municipality, by year over ten years. Expired listings are a count of contracts that ended without a sale; the same plex listed twice in a year can count twice. The failure rate is a ratio between two kinds of listing endings, sale or expiry, in the same year: it does not say how many of those plexes eventually sold after a relisting. The house and condo columns apply exactly the same definition to the Single-family and Condominium categories, which keeps the comparison honest. Average days is the measure the QPAREB publishes; buildings of 6 units and more are commercial and are not included.
