There are two types of Dual agency . .one in which the individual agent acts for both the buyer and the seller owes fiduciary responsibility to both the buyer and the seller. This is untenable and can leave the agent open to charges of acting in his/her own best interest rather than eith the buyer or the seller
The other type is Dual agency with desiginate agents. This happens when a buyer agent sell the buyer (His client) a property listed by his agency, but not this agent. In that case, the buyer's agent works for the buyer and the listing agent works for the seller.
(It not as simple as this sounds, but it is a common practice in large agencies and is both legal and ethical)
If you wouldlike to call, I will gladly explain in detail without obligation.
