Financing a Multi-Family

[Dj Samson]

Hello! This is a newbie question but couldn't find it asked anywhere else. I want to buy a multi-family building and plan on spending the next year saving up the down payment and learning more about analyzing investments. I want to live in one of the units and rent out the rest. But I'm just starting my first "grown up" job. I spent the last few months since graduating college working for myself and part-time for a hotel with low wages. How long will I need to work for this company to establish a solid track record of income before I can apply for a conventional loan?
