My sister, who has early onset Alzheimer's, has been at her assisted living place for just a month now and has not required anything more than regular rent with meals, light cleaning, laundry. On this, her second month there, she got a letter saying they were raising her rent by a whopping $1005! Is that even legal? Evidently they did so without any warning, not even a 30-day notice. I am obviously fuming. Advice? We just moved her in. Hate to have to move her back out right away.
