It hasn't traded since October 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 2002–2007, sale prices on this property compounded at 12% per year. Today's modelled estimate of £165,000 sits 83.3% above the 2007 sale of £90,000. On a £-per-square-foot basis, the last sale (£158/sq ft) was about 29.4% below the postcode norm. One historical planning record sits against the property in 2016. The record references listed-building consent, which constrain future alterations. At 53 m² it sits well below the postcode median (87 m² across 54 EPCs), making it one of the more compact homes locally.
