I am curious if SE will base the individual housing prices off how much Gil is on a server, player, FC vault, retainers etc, like they did for the FC houses.

This could be a problem for the players if this happens because, as we all know, not many people are spending their Gil so they can help save for the FC houses and be ready for personal houses when they release. If everyone has enormous amounts of Gil mountains and SE decides to do their math...we end up paying out our ears?
