Covering that much ground means treating each area on its own terms rather than applying one citywide rule. An older Caswell Hill bungalow and a new Evergreen build sell against completely different comparable sales, and a Warman or Martensville property sits under a different municipality's assessment and Board of Revision entirely, separate from the City of Saskatoon's.
REALTOR® coverage that wide only works with genuinely local comparables for each area, not a generic city number applied everywhere; a $444,700 citywide benchmark is a reasonable starting point for context, but it is not what any specific one of these areas actually sold for last month.
If your property sits in the city or just outside it, the first step is the same: find out what has genuinely sold nearby. Get your hand-reviewed valuation from Joel Dyck.
