When moving out the tenant had disconnected his washer on the 2nd floor and didn't shut off the water lines.

You MUST make it so they are forced to turn on the fan whenever they turn on the light and should actually check during your periodic inspections that they haven’t disconnected the fan motor.

I had their utilities disconnected, electric meter pulled. 

We found out the pictures he sent of the outside were the actual home, but the inside pictures were not of the same home.Mr Miller became harder and harder to contact and before we knew it his phone had been disconnected.

It doesn't matter how disconnected your command is from a prospective tenant or client.You never know when one Saturday you're the NCOIC/OIC over some group at an airshow and low and behold....IG investigation.The military and their families are a great investment opportunity due to the consistency and longevity of their demand.

However, my property manager advises against purchasing/placing dehumidifiers as she feels that the tenants may disconnect, break, or steal them. 

The only hassle i face is a 5 minute call to connect and then disconnect. 

Or you can turn off the one supply valve, flush the toilet, vacuum the rest of the water from the bottom, disconnect the supply line, undo the 2 bolts, pull it up and put it on a trash bag, scrape the old wax off the bottom and the discharge pipe, put the rubber ring on and put it back together.

If they harass me, I put them on block, and with google voice, they get the "this phone has been disconnected" message with the chime.

That it appears that some wires have been pulled out, disconnected,  severed .
