Held since January 2008 — that's 18 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 110 m² the property is well over the postcode median (77 m² across 17 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs). Today's modelled estimate of £115,000 sits 57.3% above the 2008 sale of £73,100. On a £-per-square-foot basis, the last sale (£62/sq ft) was about 17.7% below the postcode norm.
