After that, the most useful question to ask is how the agent accounts for renovations and improvements that public records miss. An agent who prices from paper data alone, without walking the property and asking what was done and when, is guessing at exactly the details that most affect your number.
Track record on comparable homes matters more than a general reputation. Ask to see recent sold comparables the agent has actually worked, not just listed, and how those prices compared to the original asking price.
The right agent for you is the one who can explain their reasoning clearly, not just quote a number. Get your hand-reviewed valuation from Joel Dyck.
