Is a Business License Required In Order To Flip Houses

[S L Martinez]

I am interested in getting into Flipping Houses and have attended a Real Estate Investment Club in Los Angeles. So far, it has been interesting and I have learned quite a bit. The one subject that has been missing is this: When flipping houses in Los Angeles, I assume that one must have a business license and one must have an IRS tax ID number. I want to know all the legal ramifications BEFORE I actually jump into this. Any suggestion?
