Yes you can! Should you decide to sell your home to a fellow player, there are a few steps to follow.
The first thing you need to do is to get the deed to your home. You can get the deed to your home in the housing market area from the deed NPC. Once you have the deed, it works just like any other item transaction. Hand the deed to the player you wish to sell it to, decide on the price, and then both of you hit accept.You can only sell a house to someone who doesn't already own a home.
Make sure that you remove all items, inside and outside your house before trading it. Anything you leave behind will be lost forever.
