Canada Mortgage and Housing Corporation's annual Rental Market Survey is the actual source for vacancy and rent trend data in Saskatoon, and it is worth checking directly rather than accepting a headline number, since survey timing and neighbourhood mix can make one year's figure look more dramatic than the underlying trend.
What is true regardless of the exact figure is that a tighter rental market changes the math for anyone deciding whether to keep a property as a rental or sell it, especially with the benchmark home price at $444,700 and months of supply at 1.63.
If rising rent costs are part of why you are thinking about selling instead of renting out a property, that decision starts with a real number on the house itself. Get your hand-reviewed valuation from Joel Dyck.
