Paper work and contract question

[Jim S.]

As with many beginners, I've spent a ton of time researching, reading, listening to podcasts, etc.  At this point, my plan is to start looking for my first deal in the early part of 2019.  I'm mainly interested in wholesaling, fixing & flipping as acquiring some rental properties.  With each day I'm starting to feel more and more comfortable with these concepts and feel that in order to avoid analysis paralysis I need to get off my butt and just jump in.  I've spent a good part of my career in sales so I'm perfectly comfortable talking to and "selling" strangers and the pieces and parts of this business are starting to click for me.  The one area I feel really uncomfortable with is with the various paper work and contracts that are needed for each individual situation.  I'm okay with learning on the job but the fear of not using the proper paper work and getting into financial or legal trouble really has me feeling skittish.  

Outside of potentially costly trial and error is there a good way to learn about the necessary forms and contracts so that I'll feel comfortable with this area of REI? To me, it's the most intimidating part of what I've learned so far.
