They shall go to Inspira and remain there (especially with the transfer of the pricing structure) unless Inspira gives me reason to move them.

Or what is the reason? 

The owners who switch to a PM come to me for the same reasons Drew said above.It is not rocket science, most folks hit a point where they no longer want to trade their time for money. 

In my market there are 2 reasons that keeping is smart.  1) the historical long term appreciation is on going, going back to when records started tracking the appreciation 2) the property tax is near fixed cost.  

The second company had a PM contract and due to other reasons we did not continue their services after a couple of months so tax stuff did not arise.

What is the reason that you are not having success?

If it has any basis at all (such as you left the apartment during your lease term for what you felt was a justifiable reason and stopped paying rent, but the landlord disagreed) then you may be better off paying a rather small settlement.  

I stopped reading after reading your subject line...know this:The #1 reason why landlords fail is due to their failure to manage to the lease (Source: American Apartment Owners' Assn). 

I imagine a lot of the reasons will overlap with the previous topic.  

A reasonable hourly rate would be $200-300/hr. for less experienced agents, closer to $500 for experienced agents IMO.
