Hi everyone!

I've played FFXIV during release... now I'm back and I feel a bit lost. I've quitted the game before the housing zones were introduced, so I'd like to know how everything works. As far as I read it's currently not possible to buy any guild houses and it's only possible to buy a whole guild + their housing spot. Could someone please explain why it's not possible to buy a house without an empty guild? This confuses me bit


Thank you so much for your help and I'm really sorry if my questions sounds a bit dumb.
