Should I start an LLC before actually purchasing a property?

[Kris Baldwin]

I'm looking to eventually get into investing in real estate full-time. Right now I'm looking for a couple of fix and flips a year, and I'm open to other strategies as well, buy and hold with cash out refinance is appealing to me. Since, I intend invest full-time and run my investments as a business, would it be best to form LLC prior to investing? All input is appreciated!
