Prospective house buyers:
Please be aware that there is a 24 hour cooldown timer between when you first purchase a house and when you can purchase your next one. Additionally, houses are not immediately released for sale when you choose to abandon a dwelling.
Please do not attempt to hold houses for friends in this manner, and please be aware that your choice of house is effectively binding for 24 hours.
Customer service cannot resolve this issue, players who are in the cooldown period must simply wait for the timer to expire prior to trying again.
