No, you do not need to have a broker to receive information. Don't ever be afraid to follow up with a phone call if you didn't get a response.
I would recommend having someone that you work with consistantly so they know what you are looking for, your specific situation, etc. It will make the process smoother for you.
If you have questions, feel free to send me an e-mail, kross@cbSuccessRealty.com or give me a call, 608-235-8780.
