In Longueuil, the 5-unit-and-more building sells per unit in line with the cities tracked: at most $202,400 per unit against $159,100 at the median. It is the step where you change worlds: the loan becomes commercial (5 units and more), the down payment and the appraisal rest on the building's income, and the buyer is an investor, rarely an occupant. For a seller, the price is defended with leases and expenses; for a buyer, the unit compares with the duplex's and triplex's in the same city, listed above.
How to read these numbers
One median per year for all of Longueuil, Centris "Quintuplex" type, meaning 5 units and more. What the page measures: the price the middle building sold for, and how many sold. What it does not measure: the exact number of units in each building, the rents, the condition. The per-unit price is therefore a ceiling (÷ 5). Years with fewer than 5 sales are not published; when 2026 is missing, the reference year is named. The median plex of all types comes from the same database (plex prices in Longueuil).
