Generic guides are written to rank for a keyword, not to price your house. They cover averages across Saskatoon as a whole, which flattens the real differences between a bungalow in an established neighbourhood and new construction on the edge of the city.
What a blog post cannot do is walk your basement, read your renovation invoices or compare your kitchen against three homes that sold last month within a few blocks. Reading a competitor's content to understand general market direction is fine; using it to set your list price is not.
Joel Dyck's hand-reviewed valuation starts where those guides stop: an in-person walkthrough that documents your improvements and prices them against comparable Saskatoon sales, so the number reflects your home rather than a citywide average.
