New to Bigger Pockets - New Investor

I am new to investing in flips and rents. I have an investor providing capital for my venture allowing me to do the sweat equity - hands free. I have recently purchased the 90hr real estate course to get my license in Tennessee. I need advice from a CPA point of view, as well as, an investor point of view of how banks perceive my capital. Is it best to have an LLC, simply use my personal account, or is there another business model to maximize ability to receive funds from lending institutions, credit lines, mortgages, etc. Looking forward to all advice. And a special Thanks to BP for having an awesome tool like this to help ppl like me.
