@Cole Bossert I think @Sarah Kensinger and others have touched on the biggest qualities, especially communication.

Owners do NOT pay PMC's enough to risk violence.4) How is their inconsistent communication really negatively affecting the management of the property?

Quote from @Samuel Kim: Quote from @Tim Delaney: Does she handle all the tenant communication?

Unfortunately, my experience has been problematic, to put it mildly:* Communication: There were significant communication issues, including difficulty scheduling calls, which is still an ongoing problem.* Additional Charges: Jenny requested that I deposit on her checking account an additional $20-25k for her to purchase furniture, which I refused because I thought it was very strange, opting to give my card # instead.* Work Quality: Jenny never showed up to the house, she sent 2 people instead, she never mentioned she would not show up herself, she never asked for approval to send two others instead, they did not complete the job, and there were multiple unauthorized charges on my card.* Receipts and Expenses: Once I brought to Jenny's attention that we were 20k above budget, she refused for days to give me the receipts, saying that I needed to give her my credit card statement first.

We communicate with the tenants or have the property mgmt company communicate with the tenants throughout.

There are several other issues (undisclosed maintenance markup fees, excessive charges to our account, significant reductions to agreed rent without communication, etc).

I was very impressed with the communication and the easy process.

A good manager will handle tenant communication, security deposit transfers, and ensure a smooth transition for you.Changing managers doesn’t have to be difficult—following the agreement and partnering with a competent new PM will help you get things back on track.

Clear communication is key here. 

I always cover my experience, the brokerages experience, and expectations with communication - 9 - 5, M-F, 24 hr turnaround during business hours, and the owner can reach out to me personally when the team isn't present.
