@Dave TovI agree with @John Underwood about using social media as a means to find a cleaner.  

For example are you experienced in social media marketing?

Before calling A Tech out to check it you might want to get an electronic temp gun and check the temps at the intake filter vent and at the closet register to the unit.

One of our current renters is traveling internationally immediately after leaving us and so sending it electronically would be nice.

So far we have made many connections via social media but most have been on the coasts. 

Friends and family (best source for business early on), Cold calls, social events, door knocking, hosting open houses for other agents, social media (multiple platforms... whatever works for you), networking events, etc.Books I'd highly recommend:- Anything David Greene has written here- Millionaire Real Estate Agent by Gary Keller- The hyper local hyper fast RE agentMany more but thats where I'd start if I were in your shoes!

Based off phone conversations, social media, and judge of character, I believe I will have no problem. 

Rentec Direct ACH's  (electronic transfer) the money through a payment provider.  

A drug house will have to be taken down to the studs and it will cost you 60k to get it ready for the next tenant.BTW if you had stuck to your screening process you could have uncovered their flaws, background check, credit check, social media, prior LL, and employment verification.

I'm a little unsure of your piping configuration for each structure to be able to better advise on a solution.You can purchase a water meter from a local plumbing supply house and install it on the line feeding that building (not that difficult to do, either), and charge them whatever your local water rates are (or more if need be).We were going to do this but the city sells an electronic read water meter for $283.
