Kristina, hi. It's great to know that you are asking for advice on choosing a Realtor to assist you in buying a home. The best way to do this is to speak with folks who have had a good, positive experience with an agent. Ask you friends, work colleagues, etc. if they can give a positive recommendation on an agent. Having those names in hand, then meet with those agents to gauge how comfortable you are with them; personality clashes have no place in the homebuying process. Any good agent will gladly provide some references of their own to you, satisfied clients who are willing to speak with you. If you are not certain where you will be buying (anywhere in Chicago, anywhere in the suburbs that surround the city?), also try to choose an agent who is willing to work with you in multiple neighborhoods and communities. I have personally helped my clients buy from DeKalb to Elgin, from Waukegan to South Loop, and everywhere inbetween. It's an exciting time to be a homebuyer, and I wish you well in your adventure.
