Is a Real Estate Agent/Investor better than one who doesn't invest

I'm currently on the hunt for a great real estate agent to make money with. I just thought about a guy who bought a car from me who is making a killing(I've seen his tax return). He is a Agent/Investor. The only issue I have is that he introduced me to his mortgage broker, who is now my mortgage broker and he knows that I have bad credit. I don't know if thats a mental issue that I have or something that may have him hesitant to work with me now as an investor. I called a couple Offices today looking for an agent. I found one who didn't sound that savvy. The guy I'm referring to is definitely a specialist. How can I partner with him.

Also, should I become a Real Estate agent myself at some point? I've thought about it before because I've always been in sales, but now that I'm investing, its on my mind.
