Nice Setup!
how we make to sell the house?? or leave it ?
I am not sure I understand what you are asking. You can purchase a house if you upgrade your account and then its yours as long as you pay the maintenance fee. Then you can buy amenities to decorate and or use for crafting stations and storage- Since there wont be a wipe after open beta the house will stay with you once the game goes live. I am not sure how you would sell the houses and i know that I have no intention of selling mine since this is the house I have wanted since I first saw it. =)
i have bought a house but i dont want it anymore so how do i sell it back ? lol
You cant "sell it" you can choose not to pay your tariff by removing yourself as an owner from the house. you can then go buy another house and move your belongings... you have until the next payment day comes around to move your things out.
