A group of us ran as a slate of officers and got ourselves elected to the board.
Our board had three officers and all were elected annually and the same group had been on the board for several years. They had a sweetheart deal with a management company and too much money was being spent on management fees and the amenity infrastructure was not being maintained properly. For three months prior to our January meeting we very quietly canvassed the neighborhood gathering support as well as proxies and at the January meeting well over 100 homeowners showed up and we took over the board. We immediately initiated an audit and we were able to secure the return of some funds from the management company and then terminated their contract for cause.
People often forget that the HOA is the homeowners and not some foreign entity. If taking control back into the citizens hands is revenge then I suppose we got revenge.
