Seeking guidance. Entities and 401k

[John Anderson]

I am at the very beginning stages of entering the investing world I have been self educating through books the forums on this site and others and I on average listen to two podcasts a day while at work for the past few weeks and one subject I haven't found much information on is the actual startup of an investing company. So my first question is what would be the smartest type of entitie to start, LLC s corporation or c corporation... With the intent to start a solo Roth 401k?. Which brings me to question number two. Is a solo Roth 401k the best way to go for a retirement fund? Considering I will be the only employee in my business and of course down the road would like to be able to use those funds without penalty and self direct to invest in more deals. Any and all advice is much appreciated
