Collecting Sales Taxes, Advice Needed

[William Jasin]

I am setting up an LLC. My attorney said I can use 1 LLC for all my business but I don't know if she is thinking about all the tax consequences. Under the LLC I am going to have 2 DBAs. One is for my wholesale and flipping deals and the other is for an electronics business that I am starting. For the electronics business I think I will need a tax certificate for buying parts wholesale and charging customers sales tax. Will having the tax certificate have an effect on the real estate business?Should there be more separation?

Another question I have is about my future rent and hold properties. Should I use a separate entity for the holding company so it can be taxed as capital gains instead of as a dealer?
