How do you pay for care in a nursing home?

My mother is 85 years old and after years of mini strokes and now dementia she is unable to commuicate, move in anyway. We have a nurse currently for a few hours a day that changes , bathes and feeds her. But this wasn't enough and we can't afford to pay someone for 24 hour care...so we are thinking nursing home.

My mother's social security from my father is $1100 a month. She does have some money in a savings account but nothing that will last more then 6 months. The house we all live in has 5 people on the deed (including me).

So we want to approach some nursing homes but are afraid that if they take her social security and her savings account they will want some of the house and want us to pay for services which we can't afford.

Can you tell me what happens financially if we can get her into a home?
