Permit status changes the number more than almost anything else on a multi-unit property. A suite that cleared City of Saskatoon inspection for a separate entrance, egress windows and fire separation supports a lender's rental-income calculation, while one that was simply built without a permit generally does not, even at the same finish quality.
If either unit is tenanted, the Residential Tenancies Act, 2006 governs notice for showings and how the lease transfers to a buyer, and that detail belongs in the listing package from day one rather than surfacing during a condition period.
Joel prices a Willowgrove multi-unit from verified permits and a real rent roll, not from finished square footage alone. Get your hand-reviewed valuation from Joel Dyck.
