Family Care Or Assisted Living?

My mom is at early stage Alzheimer’s. She has some memory loss, like names, but she still knows who we are. She is physically very healthy at 87 years old, with a lot of spunk still in her. She has 9 children. Some want her with family care and some want her in assisted living. We are arguing about it. We put her in assisted living and she doesn’t like it there. We have family members that want to take care of her, but the ones that want her in assisted living say she’s safe there. Our mom does not wander or is argumentative. She is easy to take care of right now. Her savings will run out soon and then we’ll have sell her house, which our mom said she does not want sold. What do you think we should do? She does have an 86 year old sister that is sharp as a marble that wants to take care of her. My mom loves her sister. Need advice. Thank you.
