I have a small Free Company that is aligned with Maelstrom. I am considering moving it to a different Grand Company. However, I can not find information on the side effects of changing allegiances beyond the FC's GC standing gradually changing. Standing meaning the notoriety within the GC.

Will the FC lose rank as well as standing? In turn losing the FC house, FC buffs, FC expanded chest, etc... ?

Are there any other concerns or preparations needed in regard to this transition?

Also, I believe this information should be available in-game considering the significant cost of housing. I submitted two tickets but received template responses claiming GM's can not answer this type of question.
