I agree with @Michael Smythe that you need a property manager that communicates well. 

We have been customers for more than five years, we would appreciate having better communication when it comes to the property managers having Important issues to solve.Therefore, please contact me at any time at 703-420-0620 or 703-317-7078.

By the way, your attitude and the way you communicate with people is something to behold.PS.  

It may be that they are underwriting the property at a significantly different valuation than what you are using or that they feel that you or the deal is excessively risky.Great advice here, and a good HML will have an account rep or someone to communicate with you through the process so that you know. 

For example: Flagstar has retail, wholesale and correspondent channels. 

Ultimately, clear communication and expectations handled in a respectful manner can avert any issue.

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

I have three listings, 1. unit with a pool and hot tub, 2. unit with a hot tub, 3. both units together as a 12 sleeper.Gross monthly income (after booking channel fees) for the first unit over a 7 month period was $7309.Gross monthly income for both units over a 14 month period is $11,297 (after booking channel fees) As a long term rental the combined rent would be in the region of $5500.Is it possible to sell the property based on the income generated by the STR business or would the value always be based on bricks and mortar comps? 

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.
