What do I need to look into if I need to put my spouse in some kind of care facility when I can no longer take adequate care of him?

I try to keep up with post the posts on this site, perhaps I have missed some in regards to my question. As I read some of these posts the questions they ask make me ask questions that I had not thought about. I have read some about POA and I have that in the works. Althou my husband is in the very early stages of dementia I want to be informed as much as possible. The question I asked may never come up in my situation, but would like to know how others have handled the finances of the extra money it takes to have to put one in a qualified care facility. Would I be able to keep my home or if I decided to sell it how would affect my situation. So many questions and perhaps I am jumping the gun so to speak but feel I need to start looking into the future IFS. I am sure there are numerous other things that will come up in the future that perhaps others can help me shed light on some of those things.
