My mother recently had a stroke and is in nursing home care and now needs long term care. Any advice on her house?

My mother recently had a stroke and is in a nursing home care now and will need long term care. My brother has always lived with my mother has always helped her out and taken care of her after some medical issues. She never did anything with the house, it is still in her name as an asset. Is the only thing we can do now is buy the house for fair market value or under an assessment value on the house and then work on the spend down process to eliminate asset value for her?
