Meaning they went into a standalone bank account (not mixed with your other personal funds). 

It's standard contract.

Quote from @Amanda Dobbs: Is there a place to find Private Investors as in one person?

Many banks limit personal loan amounts.

From what I have researched they seem legitimate but the person I am working with is flakey, takes forever to answer questions so I thought I would see if anyone else had experience with this lender.  

We have done it both ways where we fund purchase and they cover rehab but if the individual is less experienced we do not do it that way, we have them put more money into the deal from the start and fund the draws, reason why is we also had a deal where the person said they would do this and never did anything and property sat and loan matured and it was a pain.Just recognize you will still not get 100% financing for the purchase, so you are putting money in up front. 

You missed an important item: Depending on how a person does #1 or #2, it could get them: A fast-pass to the "Principles Office" for "bullying" and now there sitting in "detention".... 

but keep in mind CA has higher taxes and reg fees and I’m not doing more than 1-2 flips (short timeframe flips)  a year and many years do 0 flipsDo most flippers put flips into LLC Or in personal name (sole proprietor)  in CA (where you must pay $800 yearly plus accounting and other fees $300to $600+ yearly to maintain LLC) Pros for personal name-save on taxes accounting.

Affordability for the average person is essential, in my opinion. 

We can close under a personal name, but most chose the LLC option.
