Playing DAX Percentiles on the mean (or is that median) Streets of Ireland

A significant event in Ireland's property market happened this week, there's now a publicly accessible register of all residential property sales.

This is something that should have always been available but became absolutely essential as Ireland's property boom unravelled, with prices down 60% since 2007. Not just, to help potential vendors and purchasers find a price point in a collapsed market, but also for all householders, now that a self-accessed property tax is due mid next year.
