On the PTS for a couple cycles now we have been able to gift houses (although only those the player gifting doesn't own lol) and my housing guild talks about it every few days wishing those with crowns could gift the limited time houses to those without in exchange for gold or w/e.
If you let us buy a house on the Crown Store without forcing preview - that would allow the gifting interface to work just like it does with the other crown gifted items!
