What these lists usually reflect is advertising spend, submission volume or a referral arrangement with the site, not a comparison of sale-to-list ratio or days on market, which is the data the Saskatchewan REALTORS Association's MLS® system tracks and which actually reflects an agent's pricing skill.
The one genuinely reliable check costs nothing: the Saskatchewan Real Estate Commission's public register confirms whether an agent is licensed and in good standing, which a ranking site's badge does not guarantee at all. Joel Dyck holds 72 five star Google reviews, which is a different kind of evidence than an unexplained rank.
Ask any agent on one of these lists for their actual recent sale-to-list ratio rather than trusting the rank they were given. Get your hand-reviewed valuation from Joel Dyck.
