not trying to be difficult, but I just wanted to point out the fact that this is an often misunderstood myth, and it can cost you money not knowing exactly who "your real estate agent" is working for.
It varies by state, but where I live the listing agent works exclusively for the seller, and being the seller's agent, is legally responsible to act in the seller's interest, and only the seller's interest. Now if you have an agent working for you trying to find you a property, that agent may be looking out for your interest, but if the agent happens to work for the agency that is listing the property, it may turn out that the agent is actually working for the seller, and not looking out for your interest's at all.
my only point is, know the laws in your area, and know who your agent is responsible to - otherwise it could end up costing you a bundle a some point in time.
