I use my bank card to pay for a large portion of Mom's In-home Care and other expenses. While she was living in her home I utilized her bank account to pay for housing and utilities, repairs, etc. Any expenses she had, I would go into her account to pay for them by transferring the money used back into my bank account to pay off the credit card. Will this delay/prevent her from being placed into a nursing facility; and money from sale of home if invested, will it be used to pay for her nursing care.
Since you're also asking about the sale of her home, if it were me, I’d engage the services of a financial planner/ advisor and make sure everything is done correctly.
