My mother was admitted to an assisted living facility 2019. A financial guardian was appointed. Thoughts?

You need to contact the court that appointed this guardian.

If she is not on Medicaid, why is the financial guardian bringing up the income and asset limitations the apply to Medicaid recipients?

Thank you for following up Anderson.

I think Barb has nailed it. Once Mum is on Medicaid her funds cannot be used to maintain a house. As the person living in the home, it was your responsibility to maintain the house insurance, property taxes and maintenance.

It is sad that it is not maid abundantly clear to families who is responsible for what. My family has a trust. The Trustee, who also has lifetime use of the property is 100% responsible for taxes, maintenance and insurance. He has let maintenance slide to the point the roof has been tarped for 2 years. Some but not all of the property taxes are paid by rental income.

If mom is on Medicaid, then there is no money to pay for maintenance of the home. If you are going to live there, you need to be paying for the property taxes, the insurance, the utilities and everything else.

In some states there is a "caregiver" exemption for adult children who have lived in the home and provided nursing home level care for some amount of time which prevents Medicaid from placing a lien on the home until the caregiver sells or dies, but it does not sound like this is the case.
Even if you HAD a caregiver exemption, you will still be responsible for those bills.

Lots of missing information here.

1 Why didn't home owners insurance cover the cost of repairs?
2 Is Mum on Medicaid?
3 What are Mum's health issues? Does she have dementia?
4 Who did you ask for reimbursement?
5 Did Mum have POAs in place?
