I suggest meeting with at least a couple of Realtors. Have each show you a few properties, and just notice how they answer your questions, what they seem to know about the neighborhoods, whether they answer your calls, etc. Trust your instincts and who you feel best listens to your concerns and needs.
Some agents in their first year may do a better job than the busy, seasoned agent who delegates his business to assistants.
Wishing you good luck and hoping you find the right Realtor for you.
