Recently licensed as a REALTOR. Now how do I buy houses?

[Cody Holbrook]

I'm new to real estate, and this might be the dumbest question ever, but you've got to start somewhere, right?  I searched online, but searches don't deliver the answer because I don't know how to ask succinctly.  I want to be prepared soon in case a deal comes up that I need to jump on.  I'm so new and getting setup, I haven't spent any time learning this from my broker or a mentor.  I don't have a mentor :( . 

If I find a motivated seller through a marketing campaign, and I want to buy their house with a cash offer, as a REALTOR, what contracts do I need to sign with them? I know I have to have them sign a disclosure that I'm a licensed real estate agent, the purchase & sale agreement, what else?  Do I have to do it through my brokerage and split the commission?  

Is there a book or a page on this site that describes the step-by-step process?  

I also want to learn how to wholesale as a licensed agent, which I know has more requirements and restrictions.  My broker mentioned not being allowed to do double closings.  I'm licensed and working in Tennessee.  

I appreciate any info, links to info, or recommended resources.

Thanks.
