Held since September 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 40 m² it sits well below the postcode median (58 m² across 73 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £114,000 is 37.3% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£193/sq ft) was about 19.8% below the postcode norm.
