I am a Real Estate Broker. I have a accuantance that has submitted an offer to buy a home. The offer was accepted but escrow was cancelled, buyer did not get along with their agent. This accuantance would like me to now represent them in the purchase of the same property. At what point can the client use me for representation without me being accused of pandering. I am not soliciting this person in any way. They do not want to deal with the original agent again that is one reason the escrow was originally cancelled.
