When fully completed she is hoping to do a cash out refi to pay off the 1st mortgage plus the rehab funds invested in the home roughly 150k private financing. 

As far as funding a purchase in an online auction, you can look into hard money or private money.

he is now at a point where he is not allowing access to the property to get the repair done and sending me threating email that he will not pay the rent because the repairs are not done.

Try Republic bank, local privately owned.

Or can I just do the LLC and a bank account and separate email address for contacts?

Not sure if anyone is interested in possibly partnering or providing short term private financing.

You get text and email and phone call if you want of who is going in, what time, what company, their contact info.#3.

You won’t regret it.9.It’s never about you (i.e. me)It’s not about what I have to sell, it’s not about when my current property under contract closes, it’s not about what I want in a conversation – and on and on.For example, when someone writes an email and starts out “I just wanted to…” Don’t do that.

Either for guidance and/or to exchange deals- You also want to network with the various tradesmen you'll encounter with your projects, like contractors, home inspectors, title companies, investor friendly realtors, hard money lenders (especially until you gain access to private money).

If not, I'm available for a private conversation to discuss your strategies and current situation.Cheers!
