19 Year Old Buying a 3-plex What are my financing options? 203k?

[Jeremiah Guenther]

I just turned 19, and am currently trying to jump head first into real estate. I have only a few thousand dollars saved up, a brand new credit score. I found a Triplex that just hit the market in my current town. The asking price is 129,900, and average rent a unit should be around 700. Instead of renting and apartment I would love to house hack with this triplex. 

I want to make a move on the property before it is gone, but I am not sure what my move should be. I cant afford to put 20% down being that I just do not have that money. I think my best option would be a 203k loan but I am not even sure who to start talking to about this loan. Should I go around to local banks, or maybe online lenders. 

As anyone might be able to tell, I have no experience and am obviously lacking confidence at this point in my career, but I am extremely motivated to learn and have a high risk tolerance. 

Would a 203k loan be the best route, or should I explore hard money, among other things?
