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. Today's modelled estimate of £106,000 sits 112% above the 2008 sale of £50,000. On a £-per-square-foot basis, the last sale (£116/sq ft) was about 67.6% above the typical sold price in the postcode. At 40 m² it sits well below the postcode median (67 m² across 4 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 75% of similar EPCs).
