We need a lot more information to give any advice. If your mother applies for Medicaid, the house will be an exempt asset until she passes. At that time the state can opt to recover expenses when you sell the house. If there is no one living there, you may instead want to sell the house upfront and use the money for your mother's care. That would save you from having to invest in maintenance, insurance, and taxes for a vacant home. If you rented the house, the money would be income, so you have to make sure it wouldn't disqualify her for Medicaid.
