First question I have for you is are you a first-time home buyer?
The way you find a buyer agent is to start talking to Realtors. Sure some will tell you that they are experts in one particular area but you need a well rounded buyer agent. Someone who is an expert in every aspect of real estate. Just knowing the difference between a split level and a cape isn't going to help you in the long run.
What helps buyers is an agent who is ethical, honest and will fight for their clients no matter what. One who will put their client's interests ahead of their own and not just want a commission check.
I just had an entire deal fall apart recently because the seller's agent didn't want to present my client's offer because the agent didn't like it. No agent has the right to decide which offers their clients see or don't see.
So, in answer to your question, you need to talk to Realtors and ask questions and at the end of the day, which Realtor is going to the best Realtor for you and help you in every way.
