Keep in mind all this stuff is uber regulated, very detailed, far from simple.

What's the process & requirements (e.g. copy of lease agreement) for getting one and would the MTR tenant need to arrive early enough on check-in day to get to the municipal building that probably closes at 4 or 5 PM?

See if you can roll anything into zero interest cc and knock off the higher interest stuff.  

Stuff happens, who knows what hidden BS can be found on a purchased property ESPECIALLY a D-class "garage price" home.

Hiring a PM can save you time and headaches by handling tenants, maintenance, and legal stuff.

That stuff I can hire out more in the future but I am choosing to put more of my maintenance budget in my pocket for now. 

A lot of folks were plucking stuff off the MLS, putting a tenant in place, and cash flowing.

Do you know your stuff or not?

I would take a couple days and go down there (preferably with a friend...rent a U-Haul truck and go get furniture from thrift stores, antiques stores, and even buy some new stuff.

Sorry you are dealing with this, but the fact of the matter is, this stuff happens to all of us, but especially new, self managers.
