I think it's bizarre to keep the pricing structure for L and M size houses the same as ARR when there aren't many of them compared to the size of the player population and the amount of gil in circulation. There has been more than enough time for players to create alts to increase their chances. It does not seem like new wards are in the works.

With the current supply and demand (and no auto-demolition), it seems reasonable to me to see at least 200mil on a large size house. There are more than a couple of players that can afford over 500mil for a large size house for their FC.
