How to read these figures
One price per year and per type for all of Quebec City. Ten-year increases are read with the number of sales beside them: a triplex at $635,164 on 142 sales in 2026 is a solid benchmark, a quadruplex on 61 sales is an indication. The years of decline shown are often changes in the mix (more small buildings sold one year) rather than a real drop; read three-year trends. The price per unit does not replace the gross rent multiplier, which is in our plex-per-unit pages.
