Who is watching your back?

If you need help buying a building site, do not expect the seller's agent to be on your side. They may appear to be wanting to help you, but by law, the have to tell work for the seller. Some will inform you of this or encourage you to agree to dual agent. That is, “I am working for the seller, but I can work for you also. I will not share secrets between the you and me, just as I won’t share secrets I have with the seller." Unfortunately, all to often buyer's agree to this dual agent scenario. It is the easy path to follow. However, it makes about as much sense as being charged with a crime and using the prosecutor as your defense attorney.
Don't do it. Get a buyer's agent.
