Need advice on first time investment

[Anjelica Allen]

I moved to Chicago with just a backpack an $100 to my name and no credit. I'm working extremely hard to get on my feet, and now I'm ready to advance.

I'm now seeking to buy a multi family unit 5+ unit or commercial property in the city of Chicago. But the brokers I've been dealing with state it would be too difficult for a commercial loan. And that I'm only approved for fha 250k multi fam unit 3- unit. 

My question is, how do I improve my chances for a better loan offer or assistance in commercial property? 

Please Note: I have no family or friends to co sign.
