I don't own a personal house and none of my alts have purchased an FC house from the placard.

Cannot enter lottery to relocate the FC house:
Lottery entry and plot purchase unavailable. No more land may be purchased on this world by characters attached to this service account.

You do not have a character on the same World on the same service account that purchased and maintains a free company plot
* If the character in question purchased the plot, they may still submit a lottery entry for the purposes of relocation.
