Help analyzing a fourplex in Oklahoma city

[Luis Gonzalez]

Hi, 

    I am looking into a fourplex and I am hoping someone could help me in analyzing the deal and how I can structure it with a hard money lender. What are some of the more common things to factor in on a fourplex to see if it has a potential cashflow. Also, I am thinking of going through a hard money lender to get funding for the deal, is deals a good option? if so, what kind of loan would be better a regular loan or interest only loan or is there another option? Sorry for all the questions I am dead set on getting my first property but want to make sure I don't miss anything. Any tips are greatly appreciated, guys.
