Question from a neophyte

[Christina Lee]

Hi, I’m just blown away by the tools, advice and generosity and rich community here on BP! I’m now beginning to learn about real estate investing and have gotten in touch with a real estate broker who I found here on BiggerPockets. Before seeing a property she sent paperwork that she wants me to sign in order for her to work with me. Is that typical? When I have looked at homes in the past with real estate agents (with me as a potential buyer), I do not recall being asked to sign an agreement. Any advice is appreciated!
