Kan U reed this?
I won't embarrass the schnook by linking to his blog, but I came across this on the internet, from an article entitled, "How to choose a good real estate agent"

A bad real estate agent would get easily irritated if you rejected the first house they present to you. It would look like they are only interested to get the commissions than giving you more criteria for a house.

Another example of it is that bad real estate agents are the ones who require a fee before they even start to show you the houses. This fee is used to guarantee themselves that the buyer is will only buy a house through them.

Here are examples of good real estate agents:

A good real estate are often patient when you reject a house after the other. This would mean professionalism and can mean that they want you to have the best deal possible.

Another way to determine if you hired a good real estate agent to sell your house is that they make the house look presentable as possible. They do what they can to sell the house as soon as possible and looks everywhere for prospective buyers.

It's pure prejudice, I know, but I'd prefer an agent who can put together subject and verb.
