Caswell Hill's large early century homes were widely divided into suites and rooming accommodation through the middle of the twentieth century, well before the current permitting regime existed. Some of those uses are legal nonconforming and some are simply undocumented, and the two are worth very different amounts. Before you accept any income based number, confirm the status with the City of Saskatoon rather than assuming the arrangement in place is approved.
What buyers and lenders pay for is compliance. A suite with a permit, proper egress windows, fire separation between units and its own entrance is income a lender will partly credit. A suite without those things is a renovation project priced as a single-family home, and the insurer may take the same view. On a house of this vintage the $400 to $600 inspection is essential, because knob and tube wiring, cast iron drains and foundation movement are all common here.
Conversions of this kind almost always contain work nobody recorded. Framing, plumbing, a second kitchen, insulation and electrical done across several owners leave no trail in public records, and online estimates cannot see any of it. Joel Dyck's hand-reviewed valuation separates the permitted from the unpermitted and prices the property against genuinely comparable Caswell Hill sales.
