communication expectation with pm

[Summer Chen]

Hi Friends, 

I have tried to connect with several property managers for both MTR and STR. It seems so far most of them are not able to respond promptly or will not be able to provide prompt communication if I hire them as the property manager. The one I have been working with constantly ignored my questions/concerns/inquiries or did not reply for days or weeks despite that 24/7 communication is promised in the agreement. Is this the norm for property managers? What is the reasonable employee/property ratio for a property management company to ensure that it may keep up the prompt communication? Thank you.
