This is basically a bunch of LLCs that are treated as one big LLC, where each member LLC is a "cell" of the parent LLC. 

A better approach is to understand that a GC's profit and overhead ( tools, insurance, truck costs, license fees, salary, supplies, gas, computers, cell phone, etc.) has to be IN THERE SOMEWHERE.

2) When you've been showing up on these people's cell phones and computers multiple times, and you've showed them you can sell their house fast, or you can close the transaction fast with a quick cash offer...

I live in California and but the property values are too expensive for my blood so I've opted to travel to southern Michigan once a month to do my investing.

I know just enough about our taxes to get my blood boiling; after that I pay my accountant well. :)Positive:  very landlord/investor friendly, which I do not take for granted!!

So I found someone to give me the seller's cell number and called him to ask why he was selling.  

This is probably time to mention that I am telling you to be aware that there are many blood-suckers on the Internet and just be aware of their intent and they know how to sell based on emotion to sell things you do not really need and real estate brings in a bunch of money from beginners that have not learned yet to be aware of them.I do think that technology has much to do with effective marketing and sales.  

Message me your cell.

Although our projects have been long in terms of time, all have been initially bought with cash and renovated by cash, blood, sweat, and tears.

Real estate is years of blood, sweat, and tears before the "passive income" phase kicks in.
