Total newbie, how do I learn what multifamilies are available?

[Scott Kammerer]

Hi BP, first quick intro followed by my goals and intentions: 

Vegas resident. My income is $64k annually before taxes plus another $12k annually, tax free. No wife, no kids. I recently cashed out of the stock market and have about $50k in liquid cash. I also have about $20k in available credit and am virtually debt free.

Goal: I would like to find a duplex/triplex/quad to purchase with a 0% down VA loan and move into one of the units and start to get my feet wet while making some money. I'm not looking for an Earth shattering ROI here, I'm not that guy that thinks he's going to luck into a 20% cap rate and ride the easy wave to riches. As long as my financial situation is trending in the upwards direction, the knowledge and experience ROI will make it more than worth it to me.

Which brings us to this post, and frankly, I'm so new and overwhelmed at this point that I'm not even sure exactly what question I should be asking. Are there agents in town that anyone can recommend that specialize in multifamily?  I'd really like some assistance from someone that would have access to sales that aren't listed on the Zillow/Trulia type sites because those all seem to either have an offer on them or are sitting on the market for very obvious reasons. 

I guess if I were going to try to whittle this down into one simple question it would simply be: Where do I start?
