How do you get a castle in wizard 101?

you have to be on a certain level to be eligible to move out ya dorm i think somewhere around 15-20 you talk to simeon in ravenwood and he send ya on quest to see da castle shopkeeper in the left side of the furniture keeper's shop in the shopping district. castle's cost lots of gold so i suggest you battle as much as ya possibly can to get all the gold ya need or just buy it with crowns.
