needing suggestion for big real estate investment

[Nathan A Waggoner]

I am currently living in Missouri; I have one house rented out and am planning on getting more. My question is while I was looking on redfin, I found a big 14-unit buildings that is for sale around $3 Million. I never applied for a Unit that big and was wondering if I should try to get a loan (even though I don't get much income right now). and if how what is the process, is there a way to get the loan without putting money down, etc. the only reason I am asking this is I have no experience in this and it practically me jumping from one house to a 14-unit and am trying to figure out if this is a right move. 

Thank You
