Another story I meant to link here long ago is this real estate listing for an entire Scottish archipelago.
For £250,000—approximately $398,000—you can be the owner of "a wonderful and remote island group... a small archipelego centred around two main islands 25 miles north east of Lerwick, Shetland and extending to about 600 acres in all." It comes complete with a "private airstrip" and seasonal wild flowers.
Perhaps you want to establish a writers' residence. Perhaps you're fed up. Perhaps you want to declare a private city-state. Or perhaps you simply want to reinvigorate the struggling private island market.
Whatever the case may be, "a charter flight can also be arranged from Tinwall just to the north of Lerwick."
