Newly formed LLC’s first purchase financing

[Ruzanna Davtyan]

Hello,

I have experience in residential RE but not multi-family, I would appreciate some coaching here. 

Currently looking to build a team of agents, accountants, attorneys, developers, insurance agents and bankers in Scottsdale, AZ to buy my first building. I see a big hurdle though. If I form a new LLC or a Corp to buy the building, how will I finance it, given the company has no history? I can't put my own money down, since that would be mingling personal and business assets.
Is this a case where you add a partner who puts down the money for equity? And if yes, what is a normal split?

Thank you all.
