Hi @Jeff Kennedy the only concern with allowing the tenant to provide you the credit report themselves is that they could easily create a fake report.  

Hello,If I plan to put no more than 2 properties under an LLC, do I need to create a separate bank account and/or email account for each LLC entity?

Here is the rundown:http://www.homebuyinginstitute.com/news/hud-issues-fha-flipping-rules-626/

You could also create an LLC, get the property under contract with that LLC, and then transfer the LLC to your buyer.

Also, when I was making offers, it was just over a week before the government changed their lending rules so I either had to purchase a place or wait and save up even more of a down payment otherwise I would have been priced out of the market.  

Create an LLC or some kind of legal entity where I can pool together funds from friends and family to make investment purchases.  

You'll likely have to create/modify a standard buyer commission agreement.

Hi, my name is Antonius and I'm looking to build and create wealth to become financially free.

I prefer to hold on to it and create the passive cash flow through renting, though what you describe does make sense for long run.
