What it changes when selling or buying a plex in Longueuil
At 27% failure, Longueuil is in line with the cities tracked for plexes: most sell, but about one listing in three goes back without a buyer, almost always because the asking price does not hold up against the rents and the rates. The average of 43 days says the same thing: the well-listed building goes within weeks, the ones that linger pull the average up. For a seller, the right price on day one keeps you out of the expired column. The number of plexes for sale and months of inventory, year by year, are in plexes for sale in Longueuil; the same count for houses is in houses that do not sell in Longueuil and for condos in condos that do not sell in Longueuil.
How to read these figures
One count per year for all of Longueuil: what expires, what sells, and how long plex sales take on average, with the house and condo failure rates alongside for scale. Expired listings are the visible part of plexes that do not sell; withdrawals and cancellations add to them, and private sales, frequent for small buildings, are not included. The mean days on market is pulled up by buildings that linger. Cities with fewer than fifty plex sales a year move by a few expired listings from one year to the next: read the plateaus, not the decimals.
