I don't know about the States rules and regulations but in Canada event the privately owned senior residences have to answer to the goverment to justify such a large increase.....isn't there a "watchdog" agency or organization that you could contact to see if such a huge increase is allowed.

I would investigate this.......sounds like a money grab to me. If nothing else write to the editorial page of the newspaper with your thoughts and get the old pot stirred.....

Bad publicity can work wonders sometimes!!!
