This is not a mobile home but it seems this is considered "tangible property" however this is only home she owns - so is this her homestead which is except from Medicaid - live in FL. I'm her daughter who is also on deed but I do not live there. She is a widow.
Parenthetically, if the property has a deed, you should remove your name from it. This is best done via a quick claim deed. The new deed should be established as and "enhanced life estate deed" aka "lady bird deed". Do a search why this is important. Bottom line: It will avoid the property going through probate.
