You're the seller of a house and YOU have trust issues? FYI, you have no physical deed that can be traded in any way. The buyer has to pay you in full in which then you can't send him a deed to the house. You must actually demo the house and relinquish the plot back to the game server after he pays you, in which, he has to pay again to purchase the plot. The buyer is the one who has all the reasons to have trust issues, however, in such cases where a player is legitimately ripped off, a GM may be able to step in (and they have) to resolve the problem, such as forcing the offending player to relinquish his land and giving it to the buyer, which may well include a temp ban on the player aswell, in which you are thrown in jail (YES there is a jail in this game)
