I have a commission, ethics, question. There is a family, which has a very competent individual; has bought many houses on his own, sold them on his own; retired doctor who at one point had a real estate license. His son has in the last month become a real estate agent. The father is looking to buy a home in an area that is outside his son's mls area, but still inside his son's license area. The father knows what homes he wants to look at. What needs to happen in order for the son to ethically collect full commission?
