That is absolutely gorgeous! On the other hand:
I intern doing business valuation and we have a lot of people who value the land for us. This seems severely undervalued, but I would assume anyone able to afford it in the first place would do extensive research and whatnot. When I read it, I was almost certain it was going to be for a single parcel of land or something... But the whole island! For anyone who loves the ocean/beach/anything almost!, that is the ultimate dream.
