It sounds like you haven't been in the presence of incompetent real estate agents... (which is good!) Anecdotally, however, by being in the market for housing for about 18 months, my level of knowledge and preparedness about individual properties, their attributes, and their value is now exceeding 80% of the agents I speak with. This is in Seattle, mind you, where prices are increasing off the charts. In a volatile market like this, it's harder for agents to learn their market and then rest on their laurels, so many fall behind.
