6. If you see a house that you want to visit, call your agent and have him/her arrange for the visit. Remember that your Realtor can represent your interests in any house, even those that are "For Sale By Owner." If you should decide to stop by an Open House that you may see, let the agent that is in the house know that you are already working with a buyer's agent and that they will be representing you on any offer made on that house.
