If I sign an Exclusive Buyer’s Agreement with a buyer client and show a home listed by another agent in my office am I a Dual Agent?

Yes, you are a Dual Agent. The buyer and the seller are both clients of your Broker, thus as a sub-agent of your Broker you represent both the buyer and the seller. Even though you may never actually meet with the seller, you must still follow the rules of Dual Agency by disclosing the dual agency relationship to your buyer and ensuring the buyer gives informed, written consent to the dual agency. Also, be careful not to disclose any personal, financial or other confidential information about the parties.
