Housing plots are indeed very limited, and phoenix is a fairly well populated server, meaning all plots are currently taken - your only chance at owning a house are either camping aetherytes or at the very least checking them very often to check for reclaims (that is how I got mine, the plot next to my FC's was reclaimed and I chanced upon it), and then buying the plot before anyone else can.

If you want a definite chance at owning a house in the future, there's some servers that are just NOT very good options for you - Phoenix, Ragnarok, Odin and cerberus are all quite full worlds, and although being in a high pop server definitely has its perks, housing is most definitely NOT one of them :P


Best of luck to you~
