Can she do this? Is this legal?

[Caroline Bertoni]

Hello everyone!
I recently acquired my old childhood home as no members of the family can care for it (and my nana whom owned it has since moved in with family so she can be cared for 24/7). Anyways, my mother moved out of the 2nd floor apartment, has left 90% of everything left in the house AAAANND ripped up the new carpets in the bedroom... Can she do this? What options do I have?
