I transferred to my server from excalibur several months after the last housing update w/ new plots was added. On Excali, I wanted a small home for myself, so the day of the patch(when they released the subdivisions), I fought the /rng log in queues and finally got on. By the time I got in, only 1 of my desired plots was left, and as i purchased it, 2-3 people came running by just missing it themselves.
As I said, several months later, I decided to swap worlds (which meant my plot on excali opened up btw)...on my new server, even though it was months after the patch, that SAME plot not only was still available, but actually 2-3 of it's same plot/different ward were available. Not only that, but there were still wards in the mist that were only 1/3-1/2 full etc...all sized plots still open (the Goblet was in some wards, a ghost town). Exodus is NOT a low pop server...and yet, months after all the additional housing was offered, there still was enough availiblity that anyone who wanted in, could be in.
Yes, NOW there are no homes....but that is mostly because, there are lots of 'dead' FC and personal homes on our worlds/ there have no new additions to the wards in new plots etc. But, in my neighborhood alone, many of the plots are owned by people who've abandoned the game/their home. All my server needs, is for those plots to be reclaimable and there would be likely enough homes just within that, to sustain us for at least 6-12 months down the road....now sooner or later, yes, other wards and areas would likely need to be opened, but SE already said their plan was to free up the abandoned lots first, give it some time, then add new housing areas from there.
And for most servers, this will work....but it's never going to work for a server packed to the max like the legacy worlds....and really, SE shouldn't base their resources on what would work for Legacy....instead, they should use resources to encourage Legacy high pop worlds to transfer to other lesser populated worlds to spread out the resource and data use. (like free transfers to lower pop worlds).
But see, yes, my server DID have enough housing to supply the demand for a very long time...it's been only recently that every plot has been 'bought up'. Many other servers were the same way. My suspicion by the way is once SE allows personal house sharing and inactive plots reopen, there will again be plenty of plots on my server that sit idle for a couple months as there will be more homes than buyers for awhile. Actually the most common topic in /FC or/l chat on my server is about 'moving up to a bigge sized home'/moving to the desired ward/waiting for Ishgard to open up...very little chat is dedicated to 'woe is me, i don't have a house/can't get one'...and the few times that DOES surface it's almost always 'I'll never save up enough to buy one because...and those folk commonly admit, they could save if they wanted to, but the FC room is good enough for them. So the perception of housing on Exodus isn't that it's some rare commodity for the chosen few, but something, that with patience and time raising the funds, is totally obtainable by most...especially once some lands are cleared.
Meanwhile on YOUR server, the first day, they'll be gone. But you're the exception, not the rule....and the most likely 'fixes' are either free server transfers to lower pop worlds to spread out the needs/use the available resources more effectively and/or add more wards to High pop worlds to compensate. But SE has been pretty direct in their plans/intentions on housing....and I'm just trying to show you how while it looks majorly broken on your world, doesn't mean it actually is, especially with upcoming 'fixes', the supply/demand works out just fine on MOST servers in the game.
