How to read these figures
Three Centris (Matrix) queries per city, same period: Income property category, Duplex, Triplex or Quadruplex type, median sale price and number of sales by year over ten years, whole municipality of Saint-Hyacinthe, harvested on October 8, 2026. The price per unit divides the median by the number of dwellings, regardless of their size or condition. The house comes from the single-family series (September 16 query). A type is published only if it has at least 5 sales in at least 9 of 11 years; under 10 sales, a year's median moves with two or three buildings. 2026 counts January to September.
