Does the current housing meet their needs?
If still living in the family home, will the person you care for be able to stay there if anything happens/changes for you?
How could it be adapted for the future if necessary?
What other type of places might be suitable if your relative had to move, say for example due to a change in health needs?
Could you help plan for this to make things easier when change happens?
Are your views and the views of the person you care for written down?
