Today's modelled estimate of £115,000 is 29.7% below the 2007 sale of £163,500, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£230/sq ft) was about 74.4% above the typical sold price in the postcode. Held since February 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 66 m² it's 18.5% smaller than the typical home in the postcode (81 m² median across 22 EPCs). On energy efficiency it sits in the top 10% of properties in this postcode.
