It hasn't traded since March 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 39 m² it sits well below the postcode median (78 m² across 18 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £183,000 is 35.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£322/sq ft) was about 64.3% above the typical sold price in the postcode.
