What form does house flipping take when business gets big?

[David Jiang]

This question is one I've been pondering after considering what my next steps are in growing my own house flipping business. I'm at the point where I've been flipping for 3 years now and, while I'm in no way a big fish, I think I have enough volume and track record to pull in serious investors who are interested in partnering with me. 

But I would like to hear from seasoned veterans who have perhaps dozens if not tens of dozens of flips going at once; what is the natural progression of house flipping once you move past the mom and pop stage? (By that I mean moving past just scouring MLS for the two or three deals a year.) What does your business structure look like? What is your day to day like? (I assume at this point, you're probably not managing the contractors yourself.)

Basically, what were the major milestones in your journey to get to where you are today? Lastly, thanks for the advice. I love the forums here.
