As a reminder:
A house becomes abandoned after the owner does not connect to the server for over three months.
A paddock becomes abandoned if it is not used by any members of the guild that owns it for more than three months.
When an abandoned house is resold:
The contents of the house's chests (items and kamas) are transferred to the former owner's bank.
The default sale price of the house is also credited to the former owner's bank.
When an abandoned paddock is resold:
Breeding objects in the pen are transferred to the guild leader's bank.
Dragoturkeys stored in the abandoned paddock are transferred to the public stable of their owners.
The default sale price of the paddock is credited to the bank of the guild's leader.
