How to fund commercial real estate investment

[Cris Z.]

hello,

I am looking to invest in a multi unit property. 6 residential units and one commercial unit (one building). 

What is the best approach to fund and structure this investment? We can pay cash, obviously will get a loan for better returns. Should an LLC be formed and then obtain a loan through the LLC to make the purchase? We intend on putting 60% cash. So 40% loan.

Seller pushing for a very quick closing. Provided we can't get our ducks lined up on 45 days (LLC formation, Loan etc,) we can just pay cash and later on figure out how to transition to an LLC structure.

Is this the typical way commercial real estate deals are completed, through an LLC? (generally speaking).
