For that house thing, you gotta go with attorneys.
For the rest, well, sounds like you saved her. Props to you for taking care of your aunt. Driving there and getting her was a good thing to do. It sounds like they were intent on taking everything from her. Nice relatives. It sounds like you have it covered, make sure whatever she has is locked up and protected from those people. More internet advice (always questionable lol) says also to make sure she has all of her estate planning in very good shape while she herself is in good shape. That includes her will for sure, and any trust she might want to set up.
