Sorry, make that 11 estate agents because the Property Bureau — "est 1988" says the sign — has recently shut, the latest victim of the credit crunch. The computers are still there but the chairs and desks are empty, gathering dust. On Islington Green, just around the corner, Evans Baker estate agents has also closed. Further up Upper Street, Dukes of Islington has gone the same way. Three estate agents closed in the space of a few hundred yards is a grim evidence of the impact of the financial crisis on London's property market.
