What you need to do evaluate the needs of your mother. The type of care that she needs will dictate the type of senior housing she needs. If your mother requires little care, then you should look into some sort of independent living type facility. Now, if your mother needs more medical or larger amount of assistance, then you should consider some type of retirement or continuing care option. Again, the best thing you can do is evaluate your mothers needs, and find the facility that will best suite her.
