Need Advice

My parents are 87 and 93. They still live in their original home but we own it. My mother has progressive dementia and constantly hullucinates that there are people in the house stealing from her , etc. She eats very little and has lost alot of weight. She quit taking any medications months ago. My father has CLL and diabetes. He gets around fairly well, but if he falls he calls us to get him up. He still insists on driving. He ignores my mom's condition. They do not bathe nor take care of themselves as they should. I know if I force them out of the house, they will hate me but I am worried about them. I also can't afford keeping the house. By selling it I could be debt free. Any suggestions are appreciated.
