Untraded for 18 years, with the last transfer in April 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2002–2008, sale prices on this property compounded at 7.1% per year. Today's modelled estimate of £390,000 sits 57.9% above the 2008 sale of £247,000. On a £-per-square-foot basis, the last sale (£281/sq ft) was about 54.7% above the typical sold price in the postcode. At 82 m² it sits well below the postcode median (160 m² across 25 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs). One planning record on file: a garage conversion approved in 2005. Past consents include a garage conversion, meaningful when judging how the property has evolved.
