Cheaper than a London flat, your own private island off the coast of Scotland

The average London property costs £1.2 million, which as we all know comes with barely enough room to swing a cat or set up a pot in which to piss. That same amount of money could purchase somewhere much more exciting, however, if only buyers were willing to look a little further beyond Middlesex. Luckily, what Britain lacks in affordable housing stock it makes up for in private islands that are, surprisingly, on the property market.
