Property management question

[Josh Skyer]

I am an investor and on the board of a Condo in NYC.  We are having issues with our current management company specifically when it comes to pushing out messages to residents. 

For example:  Managment schedules someone to inspect AC units in apartments but the residents don't know.  OR Managment schedules work to be done and the super of the building Is not informed and chaos breaks out. 

I made a suggestion for management to implement a text messaging system that is linked to a calendar. I own gyms and we use a simple system like this that is SMS text based and it works great.  An appointment is booked , added to a calendar and all parties involved get an automated text message informing them.  

Can any one offer any suggestions that pertain to property management?  Any one use any software with this functionality?
