You likely can not help her at all, but you need to talk to the broker holding your license. It does not matter if you are actively selling right now or not, you are still under legal obligation to the broker and your states real estate board.

If you can't ask your broker (you really should be able to) you could contact your local real estate licensing board. laws do vary by state, but you should still be liable as an agent if you participate and your broker should still be entitled to their share of any transactions you participate in.

YOu also need to set your mother straight, agents sell fixers all of the time, there is still a demand for them.
