Held since August 2008 — that's 18 years off the open market, well above the local norm. Across the public record there are 5 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. At 45 m² it sits well below the postcode median (71 m² across 58 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs). Across 1998–2008, sale prices on this property compounded at 11.8% per year. Today's modelled estimate of £182,000 is 22.6% above the 2008 sale price.
