Held since March 2007 — that's 19 years off the open market, well above the local norm. Across the public record there are 6 sales, relatively high churn for a single property. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 1998–2007, sale prices on this property compounded at 10.6% per year. Today's modelled estimate of £121,000 sits 168.9% above the 2007 sale of £45,000. On a £-per-square-foot basis, the last sale (£105/sq ft) was about 80% above the typical sold price in the postcode. At 40 m² it sits well below the postcode median (58 m² across 54 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
