Do I need and attorney, REI specialized CPA, or both?

[Nick Walters]

Hi there! My father and I just purchased our first house, all cash deal. We are looking to flip the house for profit. We did use the 70% rule, and it passed by a good margin. 

Now, we are wanting to know if we should establish an LLC or not, and if so do we contact a tax pro who knows REI, an attorney, or both? Maybe none of the above?

Wanting to learn as much as I can! Any and all advice is appreciated!
