- Absorption rate (year's sales ÷ new listings): 55% in 2016, 90% in 2021, 54% in 2025. Nearly one condo in two listed does not sell within the year: the asking price and the condo fees do the sorting.

What it changes when selling or buying a condo in Châteauguay
At 11.1 months of inventory, the condo in Châteauguay is a buyer's market in 2026: there are more condominiums for sale than ready buyers, and a unit listed at its 2022 price stays listed. For a condo seller, the entry price is everything: buyers compare 64 units, look at the condo fees and the contingency fund, and move on to the next one. For a buyer, this is the time to visit more than once, to negotiate, and to include an inspection condition without losing the unit. Houses, meanwhile, remain at 3.8 months: whoever sells a condo to buy a house in Châteauguay sells in the slowest market and buys in the fastest. Sell first, or negotiate an offer conditional on the sale, and do not count on the condo's appreciation to cover the gap (from condo to house in Châteauguay).
