Sharing Private housing between Characters on the same account on the same server

[Zyneste]

I was able to help 3 friends add their alt to their main's friend list and then give them housing tenancy. I'm not sure if it works anymore, but what you would do is:

Teleport on an account into a large map that you don't normally load like idyllshire. Task Manager close the game or PSN button close it during the cast bar. Then quickly switch to your other account. Use the /sea function or a linkshell to send your still online alt a friend request. Log back into the alt and accept the request. Add them to your house like normal.

You should just naturally be friends with all of your alts on the server.
