Computer generated lists which rank property markets according to the size of median price growth in the past 12 months provide essentially dodgy data. Places with only a few sales, give a medium price which is unreliable and therefore the alleged increase in the median price is a special form of dodgy data. The way medians work, if you have a small sales sample, the median will be extremely suspect. At Hotspotting, we exclude any place with fewer than 30 sales in a year.
