So, the way I understood the patch notes, and live letters concerning the topic, you can give up your house to get a new one, and then that plot goes up for sale. I didn't think you got any of your gil back when doing that, but in game some are saying there's a way to sell back the house to the NPC, or possibly trade the deed to other players.

Is there anything official out there stating you can do this? Or that you can trade a deed with another player -after- you have been using it (like when you maybe want to upgrade from a small to a medium sized plot)? Can maybe someone who has bought a house confirm old info (there was some stuff about trading deeds in Live Letter 9) is still correct?

Only thing I saw in the patch notes was about relinquishing.
