You need to set a timeline you provide that is referenced in their contract too...All this before anyone picks up a hammer.  

As a side note, this is a situation where I prefer being a hands-on landlord, because it's easy to just pick up the phone and ask my tenant about it.

I know that on my land listings, which are numerous, activity and pending deals have picked up bigly in the past 2 weeks.  

Whenever something went wrong I just picked up the phone and lined up someone to fix it.
