"Is there any questions you might recommend I ask before proceeding to make sure I process her return correctly?"

It seems this condition should be addressed; it doesn't really affect the income tax filing. You might want to consult with a property law attorney or at the least, a title company that does closings. She won't want to talk to the mortgage provider until she is prepared, in case she gets a due date notice, once they realize the asset isn't held in the same name, now.
