We do not have an agent, because there are so many houses, but invites us to look for a house through a property company and the agent wanted to "show house for sale by owner" or through us. After negotiating the price, which has accepted our offer, but wanted to have the agent, only 2% commission instead of 3%. His reasoning was that he made more money in two hours work has been reached in the house after five years of this position, he was (is an upgrade nice house) and we raised $ 5000 and had wine for $ 4000 It is not share this view, and I do not know what was said between him and the seller, but I did not do at the end and not to negotiate, nothing.
