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. At 32 m² it sits well below the postcode median (49 m² across 31 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 71% of similar EPCs). Across 2004–2007, sale prices on this property compounded at 2.1% per year. On a £-per-square-foot basis, the last sale (£319/sq ft) was about 377% above the typical sold price in the postcode.
