There is a thread on AD for player housing, likely good to look through that and any other threads from other servers that may have been made.
Hoping that Housing isn’t just another/different version of Garrisons and that it actually feels like a home within the world rather than a housing block like FFXIV and that its not Warbound, but characters have their own to assist the RP communities and those who actually want to have their characters have a space of their own to call home that isn’t just a generic X or Y house.
I fear warbound homes will actually be a negative as they will limit what can be created by players to make their characters feel unique. One way that might work if you were to force the homes to be warbound would be that the first home can be customised and seen by all characters unless you obtain a ‘permit’ of some kind for individual customisations per character, but I don’t think that is something that Blizzard would even do.
Please don’t make everything cost thousands of gold either or pay to own, have things bound to fun achievements and the world you have built instead of just paying with gold or real world money.
