Scenario: You find a home you like. You call the agent on the sign (listing agent). You speak with the listing agent about purchasing the property.
Concerns: Who does the agent work for? Whose interest is the agent looking out for?
Answer: Not yours, but the seller that hired them.
Solution: Obtain your own representation. Is it not wise to have a buyer's agent that is working for you and looking out for your best interest, providing you details about the property, requesting additional information that may affect your real estate decisions? Think of it this way... two people are getting a divorce and splitting assets, would they use the same lawyer?
