Aspen Ridge is newer construction next to Evergreen, so a suite here is more likely to be recently built and permitted than in an older part of the city, and the City of Saskatoon's permit file is the first thing a lender or appraiser checks before crediting any of that income.
Operating costs matter as much as the rent figure. Utilities, insurance, maintenance on newer mechanical systems under warranty and a vacancy period between tenants all reduce the number that reaches your pocket, and a home inspection, typically $400 to $600, catches issues before they become a post-closing surprise.
A specific answer for a specific address needs the suite's permit status and a look at what comparable units are actually renting for right now. Get your hand-reviewed valuation from Joel Dyck.
