Sounds fraught with conflict of interest...
Is ther a genuine desire among a large portion of the residents to change the management agents?
Would it be good practice for the board to request quotes from a number of management agent service providers?
Would experience be one of the criteria for selection?
While I can understand the sentiment regarding a belief that you can do a better job, many management agents provide quite a diverse service, the quality is improving and the costs are coming down when effective management companies negotiate for the best management agent deal.
Wish you luck anyway !
