If you elect not to use your own realtor, or have your own representation as a buyers representative, then remember - the seller's agent represents what is in the best interest of the seller; they have a duty to you to be honest and ethical, but the fiduciary duty is to the seller.Since the seller pays the commission, there is absolutely no reason not to use a realtor; you can still hire a real estate attorney, but in terms of having more negotiating power, it won't be an advantage that I can see in your situation.Where are you from?
