I definitely agree that it is familiarity and cost.  A lot of seniors get put into facilities and then forgotten, they know what going to places like that means unfortunately.  Dealing currently with the situation, my mother-in-law refuses to leave her home, she does need someone to come by daily to check on her but every time she thinks someone was there to remove her or if she suspected any foul play, she calls the police.  She keeps the telephone in her dress pocket.  She had early onset of Dementia along with a few other problems, she is calling the police just out of forgetfulness.  She has it set in her mind that she intends to die in her home of 65+ years.  Financially, it is better on her and the family to get home healthcare to come by her residence 2 to 3 times a week and the family in between.  The cost to be in a facility with some kind of care is $200 plus per day.  I don't think the issue is necessarily finding a place, I think it's several factors like family support, money, how much care do they really need, do they have a spouse, how mobile are they, do they want to leave their home (familiarity), are they of sound mind to continue to make decisions for themselves,  etc.  Each senior will have a unique circumstance, so far in my experience, I have not met a senior that wants to leave their home willingly.
