Held since April 2008 — that's 18 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 41 m² it sits well below the postcode median (63 m² across 44 EPCs), making it one of the more compact homes locally. 1 bedrooms is on the smaller side for this postcode, where 3 is the typical count. Across 1996–2008, sale prices on this property compounded at 9.6% per year. Today's modelled estimate of £200,000 is 35.6% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£334/sq ft) was about 95.9% above the typical sold price in the postcode.
