However, for the sell we used local realtors that my partner had used in the past for another flip.

You could say something like “let me run this by my partner/associate and get back with you.”  

Maybe you partner with a rehabber or wholesaler to build up your liquid funds. 

Another Evolve bank partner I like is Relay Bank. 

One major challenge is having our partners come up with clean and organized documentation of their track record.

Yes, a business LOC can be an option for a down payment on an MFH property, especially if your LLC has a strong credit history.

The dealer I’m working with generally works with individuals and not so much investors, so their partners don’t really offer much for investment loans, so my next step is to explore the loan aspect further and see what I can turn up.

I would strongly consider them but I am planning on waiting til early Spring to buy.

Of course, again, with the m2m, you have a strong position.

Unfortunately you will need to bring on a business partner for this deal.
