It hasn't traded since April 2007, a hold of 19 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. At 28 m² it sits well below the postcode median (95 m² across 35 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 71% of similar EPCs). Today's modelled estimate of £251,000 is 25.5% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£664/sq ft) was about 106.1% above the typical sold price in the postcode.
