It hasn't traded since January 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. Across 2004–2007, sale prices on this property compounded at 5.6% per year. Today's modelled estimate of £124,000 sits 64.2% above the 2007 sale of £75,500. On a £-per-square-foot basis, the last sale (£292/sq ft) was about 196.6% above the typical sold price in the postcode. At 24 m² it sits well below the postcode median (65 m² across 11 EPCs), making it one of the more compact homes locally.
