Although making it a humorous comment, I know that John has made the best comment possible. A property without a tenant means that it isn't giving you income (and thus isn't giving you any returns right now).
I am from a smaller part of PA as well, so I know what you mean about the dry MLS pickings. How comfortable are you looking further outside of your immediate area? You can always expand farther away if you need a better market.
Network! That's where my partner and myself currently are in the real estate process. We are currently in the process of our first purchase (here's our intro post! Shameless plug haha), and are starting to reach out to increase our network. We just joined on BP (we just found the site last week), and are looking to attend the local REIA meeting as well. The more people you know, the more sources of hearing about potential deals!
Keep searching on your own for deals. Depending on your criteria, it might take you a while to find the next Buy and Hold purchase. In the meantime, you can consider flipping (if you have the capital), expanding your market, and keep networking.
Congrats, and good luck!
