Info on larger teir prices?

My group has been working together at our business for a couple months now and we are getting ready to teir up to the largest teir listed on the site. As I don't see our business going under or any reason for it to stop growing, I'm wondering what the prices are for owning more than 65,536 sq. meters (as I'm sure eventually we'll want more land than that). We're not thinking of buying a private island (at least not yet), just owning more of the mainland. Where could I find info on larger teirs?

Thanks!

A fine question, Zany. Above 65,536 sq. meters on the mainland, I believe tier levels go up in 1/2 region levels. E.g. 98,304 m2, 131,702 m2, and so on. And with so much land, for more info on this, you will definitely want to contact the Concierge for assistance--that's Lee, Cyn, and Jack Linden. All the best with your continued growth!
