I was doing about 50%, until my broker hired in an agent just to work with buyers. Now most leads that come into the office are givn directly to the other agent and ads were run that are generating lots of calls, and I have to give all those to the other agent. I will be lucky this year to get 10% both sides. So, my broker has set it up so that, in spite of most of the increase in business being from my work, that my income will drop.
I have NEVER been a dual agent, representing both sides. I make it clear that I work for the sellers and for the buyers not to give me personal or financial information that they don't think the sellers need to know. I don't think it's possible to represent both sides and do well for both, so I just make sure it's disclosed who I am working for. I bring it up often, so the buyers don't forget, too. Like when they ask "How much do you think they will take for this house?" I point out that "As I told you, I work for the sellers..." and explain that means, even if I did know the bottom dollar, I would not be allowed to tell them because "I have a contract with them, not with you..."
Multiple offers, even with one of my own in the mix, aren't a problem. I just tell all agents and my buyers that there are other offers and submit highest and best if they really want the property. Sometimes it has been my buyer, sometimes not.
