Today's modelled estimate of £108,000 is 20% below the 2007 sale of £134,995, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£339/sq ft) was about 44.4% above the typical sold price in the postcode. It hasn't traded since December 2007, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Its energy rating outperforms most of the postcode (better than 81% of similar EPCs).
