What it changes for selling or buying a plex in Joliette
In Joliette, the average and the median say the same thing: $593,064 against $530,000, a 12% gap. The plex stock is homogeneous, similar duplexes and triplexes in similar neighbourhoods, and a seller can rely on either; what matters then are the rents in place, the building's condition and the number of units, which make the difference between two plexes at the same average price. For a buyer, it is a market where the price is predictable and the negotiation plays out over a few thousand dollars, not ten percent. The median price and its trajectory are in plex prices in Joliette; the same calculation for houses, in average house price in Joliette.
