Volume rankings on their own do not tell you whether an agent knows your specific street, your specific property type or how to handle a secondary suite that was never permitted. A high transaction count can come from referral networks and team splits that never touch your file directly.
What actually matters is whether the agent working your file, specifically, understands your neighbourhood and your property. That is a conversation you can have directly, and it is checkable in a way a blog's volume claim is not.
A verifiable licence and a real track record on comparable properties beat an unsourced ranking every time. Get your hand-reviewed valuation from Joel Dyck.
