First of all, kudos to you Calico04, for having the foresight to opt for a property that puts money in your pocket, not just takes it out of there. As Keith mentions, you cannot use the buildings' income to qualify because you do not have two years experience as a landlord. Thus, you are somewhat limited with a 36k income as far as what you can afford. My ballpark estimate of what you would qualify for is around $175k of mortgage.
There are certain places in LA that you can find properties like this, but not in Eagle Rock. Look further east, City Terrace, El Monte, Monterey Park area and there are a few diamonds in the rough. Alternately you can use the income of a family member also to help you qualify for more mortgage. From most of the younger first time home buyers I've been selling houses to over the last few years, this is a very common thing.
If you have any more questions, holla. (Yes, I said Holla on Trulia-that's just how cool I am)
