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.
Actually if I recall correctly they set it where you have a few days or maybe a week to build on the plot you purchased I would need to look it up again to quote it. They did that to prevent people from simply buying and holding empty plots.
