my property appreciation varies from a low of $2700/month to over $10k/month.   

Is this location within their sphere of competency or ability to low cost manage?

To determine the quality of a property requires to evaluate all of its return as well as potential return.  

If it's related to nonpayment of rent, the changes they appeal is very low. 

The reality is that with the super low inventory we have sellers don't have a reason to give you a 50% discount, so your numbers get squeezed and you will end up leaving cash in the deal.

Inventory still remains perpetually low.

The truth is that New Jersey, especially Northern New Jersey, is a tough investment market due to low inventory, high competition, and high taxes.

Giving the best quality of service to people is the top priority! 

•Tenants demand prompt, high-quality service and without caring about cost •Vendors seek to earn as much compensation for their work as possible.Balancing these needs requires thoughtful stewardship, strong communication, and a commitment to fairness.

I had a similar issue with one of my properties where the thermostat was near a door in a busy retail space, and the tenant was complaining the temperature was too low.
