You see, there are two "sides" to every sale. The listing side and the selling side. Most deals have an agent representing each side, so there are generally two agents involved The seller's side is represented by the listing agent. The buyer's side is represented by the selling agent (also known as the buyer's agent). Agents can deal with both buyers and sellers, but the majority tend to focus their efforts on one or the other. Some even exclusively handle either buyers or sellers. Search Homes For Sale in Arizona
