In some states, including mine, New Jersey, agents are permitted to act as 'dual agents' and represent both the buyer and the seller at the same time. They still owe both parties the very same duties, except of course, Loyalty. Obviously we cannot give our 'undivided loyalty' to two parties and our role changes slightly. If we do our job properly it really affects us more than it does our clients but it is an important distinction and some clients prefer to have someone who is working strictly on their behalf.

You have received two very good answers so far. In addition, I'd just like to add that signing a buyer's agency contract with your agent will show your agent that you are a serious buyer and also that you are committed to working with them.
