As an agent, you may contact a seller marketing a for sale by owner (FSBO) property about your client’s potential interest in purchasing the property, even if that seller’s number is on the National Do Not Call (DNC) Registry. The pitfall is that as a buyer’s representative, you may only discuss your client’s interest in the property. You cannot use your client’s interest as a way to solicit the listing. Doing so puts you in violation of DNC regulations.
