New or old plex: what it changes in Trois-Rivières
For a buyer in Trois-Rivières, a plex's year built mostly changes the condition of the major components and the work budget: roof, foundation, windows, electrical, plumbing, balconies and stairs. An old plex is often the cheapest entry, but needs a serious pre-purchase inspection and a reserve for work; its rents are often below market, which weighs on the return. A recent plex costs more to buy, with less work ahead. Either way, read the current leases and calculate the return on actual rents, not hoped-for rents. A broker on the team compares your plex with sales of the same era in your area.
How to read these figures
Median sale price (half of sales above, half below) of plexes (income properties) sold on Centris in Trois-Rivières, by year sold, for each construction era declared on the listing. Brackets are fixed. Fewer than 10 sales in a year, or a median below 40% or above 250% of all plexes (atypical sale): median left blank (n/a). 2026 runs from January to September. A plex with no declared year falls in no bracket but counts in "all plexes".
