Don't worry about the being rushed part. The auto-demolish takes over a month to finish and you only need to build a house in time to enter it before the demolish timer runs out. I think it took me a day or two to buy the permit after spending all my gil on the plot.
that is the auto though, not the time you have to build on it, if you do not build on it for a set of time, like 1 day or 5 days or something, you lose it
