Tommy B. welcome to BP!
This community is great, lots of information here to help you organize and prioritize. Buy and Hold is a great strategy, it looks like you are looking to buy, fix-up, and hold? How much rehab are you looking to do? Have you checked out the Beginner's guide here on BP?
As far as finding lawyers: It may be a little early to start contacting them, that's a personal judgement call IMO..mainly because they charge by the hour and the hours can add up quickly. That said, I would tap the network you have for referrals. You mentioned a friend in the apartment industry...they definitely have referrals. The first few RE attorney's I interviewed were a wealth of information. Interviewing anyone that will be in your network goes pretty much the same no matter who it is: realtor, lawyer, accountant, etc. Are they a real estate investor? How did they get started? What are they currently working on in their own RE investments? It's like a BP podcast, just the first few questions usually give you a sense of whether you want to work with them, how experienced they are, and what kind of relationship you can expect professionally. And in the hands of an experienced investor the response to those few questions are entertaining and full of wisdom.
Documents in general: They vary from state to state on general requirements so just be aware of that when you find templates from the internet. Your friend with a rental may have a lease agreement you can use to familiarize yourself with the language. And if you retain an attorney, they will usually have templates for you as well.
