Held since February 2007 — that's 19 years off the open market, well above the local norm. Across the public record there are 4 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. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs). Across 1997–2007, sale prices on this property compounded at 18.7% per year. Today's modelled estimate of £208,000 is 49.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£293/sq ft) was about 24.5% above the typical sold price in the postcode.
