Local Banks & Credit UnionsSmaller banks and credit unions are more flexible than big lenders and might approve you with:✔ A detailed project plan✔ A licensed subcontractor network✔ Proof of rental income history (since you own rentals)4.

Neighborhood Scout is not going to cover any shortfall you have if it doesn't materialize.you could try finding a bank or broker that will do 80% out on a refi, although probably not possible to close by the end of this month. 

For example if the house is worth 400K, but they are willing to sell it for 375k because they are avoiding having to pay 25k in agent fees, then the bank can consider the equity gap as a down payment.

Looked at HELOC on the rental, but is not allowed in Texas.Will probably apply for a 0% APR CC for a lot of expenses/material , but still need cash for labor/ vendors.Looked into personal loan , but 2 banks stated loan can not be used for investment property.

The bank says oh we’ll accept 57 bitcoin.

The idea is to expect a negative cash flow, however bank on the growth to achieve a good return.

Generally that means a separate bank account (no co-mingling of funds) and you are following the operating agreement, which could mean a meeting with annual minutes or showing that a vote was documented on decisions that require a vote as @Justin Polston noted.IMO LLCs are completely over-sold for single family.  

Do you think the bank’s loan will consist of one document, drafted by your borrower?

I'm going to assume you aren't talking about bank financing, but rather, investor/partner funds.I prefer to keep other peoples' money out whenever possible.

When it comes to the HELOC - I'd reach out to any lenders / institutions you have an existing banking relationship with.
