What it means for you
If you are buying
For a buyer, a slower market means more choice and more time to visit, inspect and negotiate conditions. Our page on whether it is a buyer’s or seller’s market in Châteauguay shows who has the upper hand.
If you are selling
Prices are holding, but selling takes longer. A property listed at the right price from day one still sells close to asking; an overpriced one sits, and that is when price cuts come. See also days on market in Châteauguay since 2016.
