Looking to buy a PM company

[Marwan Marzagao]

I am looking at the possibility to buy a PM company with 250 properties.  Personally I currently own/operate thirty.  I want to know what to expect, time needed and potential hurdles I will face and a good way to value the "business".  I have an infrasturcture I can plug into and would be converting everything to Buildium or Appfolio (another one of my recent posts).  

I would not be doing this full time as I would not be able to support my family until this got off the ground but the end goal would be to reach that point and transition fully to running and developing this operation. 

Any insight or thoughts are greatly appreciated.
