If I pay real money for a house, I expect to own that house for the entire life of the game. No lifetime ownership, no real money from me. Even when writs went on deep discount I passed.
Star Wars: The Old Republic does housing right. I can own one of every type of house. Once unlocked, I own a house for the life of the game. Each house exists as an independent instance. (The 'neighborhood' system puts too many limitations on house size and hook options.)
