Wealthy players that aren't particularly beholden to an FC (not a raider-type) can, or already are, in a surprisingly small FC, and can more or less single-handidly buy their own place. How big of a property is simply a matter of the pricing deprecation, the size of their wallets, and how badly they want to take up space and make a personal, rather than team, mark on the server.
If there's only enough lots for half the FC's on a server.. then, yes, there's a backwards bidding war going on while everyone waits to see how long they can hold out for prices to drop. Once FC's start buying land, it goes open season for ideal sizes and locations.
