That number (19 of 22) is unusually high.

If you want them to go away pay what they want otherwise tell the in no uncertain terms if they want their money they can take you to court.

If the tenant takes an unusually long time to get to the door and/or opens it only a crack when they see you, there could be something going on that they don't want you to see, such as breaking property rules... unauthorized smoking, unauthorized pet, unauthorized occupants, etc.7.

Thirty calls in a day is not unusual for us, I'm sure it does vary by area.  

One apartment had everything needed, was unusually well maintained, a great location, very generous square footage, nice bathrooms, and plenty of natural light.

That is extremely unusual and sounds like BS to me.

If you're ever uncertain if a tenant is still occupying your unit, you can call the local utility company and ask if service has been shut off.

Does anyone have any unusual policies/ conditions they have started including in their rental agreement addendums?

The frustration and extra costs you're incurring while you sort out the electricity and laundry room issues (relatively minor costs), or that the tenant told you one thing and then did another (not too uncommon), or that you're uncertain how to manage rental property and effectively work with tenants?

It is highly unusual not to have a bank account, but verify all these other criteria and see where they fall.I have not encountered a tenant without a bank account, and our company only takes checks or money orders.Good LuckGino
