You are greatly overestimating the amount of energy and time the average tenant will put into fixing anything in the property. I wish I could count on them to help in coordinating.
Well, anecdote, but in most cases I know (South Europe) it's the tenants chasing behind the landlord to fix issues in their homes, and not vice versa :P Why wouldn't one want stuff on the property he's renting (and paying dearly for it) fixed?
You would think a tenant would be eager to get something fixed. I had a tenant with a broken water heater who waited 3 weeks to tell me. In the winter! /shrug I try not to judge
