Investing in el Sud-Ouest
Rental potential in el Sud-Ouest
Proximity to downtown, the metro and the appeal of the canal support rental demand. The housing stock ranges from recent condos in Griffintown to plexes and working-class homes in Saint-Henri and Pointe-Saint-Charles, with shops on rue Notre-Dame Ouest.
