An agent working across the whole province may not have seen enough recent Saskatoon sales in a specific neighbourhood to know how a corner lot, a renovated basement or a busy street actually moves a price locally, since those effects vary block to block in ways a national database does not capture.
The City of Saskatoon's assessment cycle and the Board of Revision appeal process also move differently than a general market summary suggests, and an agent who tracks those locally can flag issues a seller would otherwise only discover after listing.
