Incorporation And Business Plan Focus

[Kendra J.]

I think I originally posted this in the wrong forum so I am posting it again here.
From the initial training I have had, I understand that it is best to have multiple corporations set up for individual strategies. One for Buy and Hold Investments and one for Fix And Flips. I also understand that it is best to have an umbrella company own the others for asset protection. My question is, which of these companies do I start incorporation and a business plan with? Since I am starting out, I am looking at wholesales and rehabs first. Do I start with the umbrella company then start the fix and flip company as a sub company? I am feeling like I am trying to solve the old chicken or the egg first question. I do not wish to start out without having a business plan and preferably incorporation (I.e. LLC) in place.
