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 71 m² the property is well over the postcode median (54 m² across 86 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs). Across 2001–2007, sale prices on this property compounded at 18.6% per year. Today's modelled estimate of £166,000 sits 58.1% above the 2007 sale of £105,000.
