As a buyer, you get to use an agent for free. I would advise you to go out and get a good buyers agent. This way you have someone who represents you. When you call the listing agent up, they are looking out for their client, not you. Call up 2-3 agents and go with the person you mesh best with. I grew up in orland park, so I would be happy to help you find a place.
