- Average versus median: 115 days against 67 in 2016, 34 against 11 in 2026. When the gap is wide, some plexes sell in days while others stay listed for months, often because the income does not justify the asking price (plexes that do not sell in Sainte-Thérèse).

How to read these figures
Two Centris (Matrix) measures, same query: "Median days on market" and "Average days on market", Income property category, whole municipality of Sainte-Thérèse, by year over ten years, harvested on October 8, 2026. Plex sales by year come from the price series of the same source (652 sales since 2016). In years with fewer than 30 sales, the median moves with a few buildings: read the periods rather than a single year. The time measures the speed of the market, not the quality of the buildings: a well-kept plex at the wrong price sits, a fixer-upper at the right price goes fast.
