Vick - I would not pay a guru or a mentor to teach me. As for learning, I highly recommend you enroll in a real estatate agent course and take it, read the books, attend class, etc. . . then pass the in-class exams. From there, you can stop or you can keep going and pass your state's exam to get your license (not required to be an investor). Taking real estate classes will help you with the real estate language. . . I learned a ton. But in the end, I did not get my license because I don't need it! I just need the knowledge!
Another comment on paying for mentoring - if you're interested in wholesaling, then your mentor will ask you to help with manual tasks and you will learn, and you will develop a relationship. Juts make sure the mentor is successful in wholesaling so you're not wasting your time.
As for fix n flip mentoring - one of the challenges as a fix n flipper is getting more cash. When you do fix n flip, you borrow 80% (or 90%) from a hard money lender, and then you have to provide the remaining 20% (or 10%) as a downpayment to purchase the property. This is where you can come in and help the mentor by providing some downpayment and then ride on your mentor's experience in rehabbing properties. Make sure they have a track record so you're not wasting your time.
