Held since August 2007 — that's 19 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. At 92 m² it's 18.7% larger than the typical home in the postcode (78 m² median across 24 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 2006–2007, sale prices on this property compounded at 30% per year. Today's modelled estimate of £201,000 is 40.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£144/sq ft) was about 35% below the postcode norm.
