Why does market knowledge matter when choosing a real estate agent?

Market knowledge matters because pricing a home wrong in either direction costs a seller money, either leaving value on the table or sitting unsold while buyers assume something is wrong with it, and that pricing decision depends on knowing recent comparable sales on the specific street, not a citywide average. An agent without that depth is guessing. Brian Beatty prices every listing from actual closed sales in the immediate area rather than a broader estimate.
