Suggestion: relocation should be subject to the same timer as first time buyers.

Then please, elaborate on the reason and benefit of having relocation skip the timer? Right now it mostly serves as a means of players being able to trade houses amongst each other for increasingly inflated gil costs. We can do without that. Folks relocating to a plot already have the benefit of getting a reduced gil cost.

It serves the purpose of increased comfort as you level up in the housing game. You should only really suffer badly once to get a house, there's no need to keep the suffering going when you want to upgrade your house as well.
Plus like others have said, it changes very little for people trying to buy their first plot. If someone relocates it just opens up a plot somewhere else. There's hardly any time wasted for people placard spamming. I did the math a while back. The difference in the time it takes to get a house between someone staying on the same plot and clicking the placard until the plot unlocks, and someone placard clicking for an hour at a time every day is only about 10%. Clicking the placard and having someone relocate after a few hours is equivalent to that later case.
Plus, that can be further reduced if you use an appropriate house-hunting strategy.

Which while I'm on the topic of strategy. House hunting anywhere where someone relocates is a sign that you aren't doing it right. You should focus your efforts on small goblet plots. Anything else will be a bit of a gamble and you should know that going in.
