In Britain until the early 1990s, agents involved in a property transaction worked for the seller as Estate agents. Now, property finders exist to represent the interests of the buyer or tenant. Today in the United States where fiduciary obligations exist, if the buyer is working with a broker other than the brokerage which represents the seller by "listing" the property for sale, he may choose to enter into a buyer brokerage agreement to be represented. (In some cases where dual agency is permitted by law, even the listing broker may represent the buyer). If the buyer does not enter into this agreement, he/she remains as a "customer" of the broker, who is then the sub-agent of seller's broker. PropertyFinders is the Registered TradeMark within Australia - Trade Mark #1081652.
