With all the new housing ideas coming in update 27 (Stonethorn), a simple, yet fun idea I had was a guestbook as a new option. Maybe design the housing item to look like a stand with the book on it. You can press "E" on a guestbook which would leave your name and possibly a short comment to let your friends know you stopped by, etc. When the owner views the guestbook they can view all the signatures/comments much like how we read through the books and turn the pages already in ESO. As a further option, the guestbook could also be customizable to let signatures/comments be publicly or privately readable.
Just an idea to add a bit more "multiplayer" interaction in the housing area of the game.
