I had started to make a thread like this last week until I found this interview again:

This will be introduced sometime after the Free Company’s personal rooms are made available in Patch 2.3, and the size will be a little larger than the ones at the inns.

The bold part is important and crushed my dreams of owning a mansion like FC's can have in a large ward like mist. Now I believe they'll be nothing more than smaller FC rooms with no physical residence or community ward.

TBH, SE has done an awful job communicating how player housing will work and STILL has yet to even address it with less than a week to launch. At this point, what details do they need to iron out before they could do a preview? They're setting us up for disappointment which will only result in backlash this late in the game.
