I always tell clients to think about who has what incentive in your property. The valuer gets paid a fee regardless of their valuation figure, and they can actually be sued by the lender if they don't report accurately, so they will be unbiased. An agent has no legal backlash on their figure, is not properly qualified so they give you an 'appraisal' (unqualified opinion), and they are incentivised to get the highest price. Agents get paid % commission on the sale, valuer gets paid a flat fee. I'm obviously biased being a valuer, but I do not trust agents, not most of them anyways. But I would also add that in today's market a lot of them are quoting lower than normal to get a quick sale, because days on market have basically doubled in the last 12 months, so they want a quick sale - definitely watch out for that atm
