Hi 1st time,
Congratulations on recognizing that you want to avoid dual agency by looking for your own agent. Very wise. You have several options. You could look for an agent through NAEBA (National Association of Exclusive Buyer Agents). Or you could choose an agent from a smaller firm like an independently owned and operated Re/Max, Century 21, or any number of "mom and pop" firms in Union County that have been around for a long time and have experienced agents, but not a whole lot of listings. You want to avoid larger firms with thousands of listings, because the chance of dual agency goes way up.
If you Google "exclusive buyer agency", several possibilities will come up like Buyers Advisor, NAEBA, and the like.
You could also interview a few good agents in your area and ask them to pledge that they will not put you into a dual agency under any circumstances. That means if you find the perfect house and it happens to be listed with their firm, they would agree in advance to refer you to a buyers agent outside their firm. Only a very few highly ethical agents will agree to that, because they have to be willing to lose money if you choose one of their company's listings. In other words, they have to be willing to put your long term interests ahead of their short term interests.
I regularly agree with my own buyers that there will not be a dual agency if they work with me. If they want to buy any of my listings, I'll refer them out to another agency and simply take a referral fee.
This is actually a good litmus test for agent selection anyway. Any agent that rebels or gets uncomfortable when you bring this up is an excellent agent to AVOID.
If you have any questions, call me anytime. I cannot take you on myself due to a busy workload at the moment, but if you have any questions I'd be happy to answer them. This can be a complex topic to discuss completely in this format.
