What mentors are looking for?

[Sophia Maler]

Hi, I'm moving my question from another thread because it really belongs here.

I'm new to REI but have some cash to work with and want to learn the business. I made a contact with a local pre-foreclosure wholesale investor in CA who has more business that he can handle and is willing to take an apprentice. Can someone please tell me what mentors are typically looking for to make it worthwhile for them?
