I could be that someone used their gil to buy the plot and is saving up to buy the permit. Had that happen to a couple fc members awhile back. They were so happy to be able to finally buy a plot then they were hit with the permit fees they had no idea about so the plot had to go unbuilt for a couple weeks while they got enough gil together.

Let's face it, its likely flippers who got a house on hold til they can find a way to get around the system, but its nice to fantasize about nice people on the internet now and then lol.
