Are you married? If you are, then on your spouse’s behalf I would say no. It really depends on your spouse’s relationship or your relationship with your mother. Even if you would be next door neighbors, you would be seeing each other everyday. At 77 years old, she is most likely already set in her ways and will not be as accepting of change too much.
Think less of the financials in this situation and more about how well you would get along as neighbors. At this age, is it more likely for her to move in with you to take care of her? Is she currently in a retirement community for a reason?
