Adding relocation to the purchase timer does nothing to benefit those looking to buy a house for the first time.

It doesn't matter whether the player who ends up with the plot was a new buyer or someone relocating - every other player trying to buy is going to be disappointed because they still don't have a plot.

At least with relocation, you know another plot is available somewhere else on your world. You have another chance to buy in the next 24 hours. If a new buyer ends up with the plot, you don't know how long you're going to be waiting for another one to become available.
