I wouldn’t consider it being punched in the face.  

I am similar to @Benjamin Jones just getting started and looking how to set things up? 

Sounds like a problem with setting expectations.

To me that's just not attractive enough to consider selling.

Once you have cash in hand, you can unlock the unit for 24 hours and let him move his stuff out.I would also consider charging an additional deposit of $500 or something, just to prevent him from leaving all the trash or stealing your refrigerator.

I'm seriously considering trying to find something there, but need to build up my knowledge and contacts of reputable agents and contractors etc.I'm interested in multi-family, STRs, commercial, self storage, and possibly even flips if the right opportunity came up.

You have one set of bills but 4 rents coming in.

I personally concur .. they charge 6k to join the club they bring in folks who have no experience and set them lose.. with so called training..

Otherwise, I would consider it caused by tenant.  

Happy to chat...being a local GC takes out a lot of the risk of the biggest variable for most investors (unpredictable rehab costs) and also allows you to consider more options than the average investor, with your rehab costs being significantly lower.
