Saint-Constant belongs to the same pool as Candiac, Delson and Sainte-Catherine, but with prices generally below Candiac at comparable floor area. That makes it an interesting entry point in the Roussillon area.
What structures the market
The exo station on the Candiac line gives direct downtown access without driving over a bridge. That is a concrete argument for a specific buyer segment, with a price premium localized around the station.
Vieux-Saint-Constant keeps an older core with mature lots.
The newer sectors (Domaine des Sources, Saint-Constant-Nord) carry the growth of the last twenty years: larger, more standardized homes, reliable comparables.
Sainte-Marguerite and the rural fringes offer larger lots, sometimes not connected to municipal services.
What to check here
The residential construction warranty for properties under ten years old.
Drainage and the water table, since several sectors were developed on former farmland. A finished basement with no clear French drain history deserves a targeted inspection.
Septic systems and wells on the outskirts.
