New or old condo: what it changes in Châteauguay
For a buyer in Châteauguay, year built mostly changes three things: condo fees, the state of the contingency fund and the major work ahead. A building from the 80s or 90s often reaches the age of major work (roof, windows, parking): ask for the contingency fund study, the minutes and the syndicate's financial statements before your offer. A new condo costs more to buy, but its first major work is far off; check whether it is covered by a construction warranty and what condo fees are planned. A broker on the team compares your condo with sales of the same era in your area.
How to read these figures
Median sale price (half of sales above, half below) of condominiums sold on Centris in Châteauguay, by year sold, for each construction era declared on the listing. Brackets are fixed; "2020 and later" only exists from 2020. Fewer than 10 sales in a year, or a median below 40% or above 250% of all condos (atypical project): median left blank (n/a). 2026 runs from January to September. A condo with no declared year falls in no bracket but counts in "all condos".
