Housing should be account bound....

If this is just to fix the house flipping, all they need to do is start the reverse auction at 10 times it's current level. Flipping eliminated. Gil hole boosted.

That would only benefit the really rich players. Small houses (for example) on my server are between 4 and 5 million. It's not too hard for someone to get that much together for their own personal house, but 50 million? :S Sure it'd stop the house flippers at the cost of blocking a lot of genuine players.

The only way to stop house flipping is for their to be sufficient houses that there is always a house available for someone to buy if they have the money (i.e. new wards constantly being added as needed).
