Held since March 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. Today's modelled estimate of £242,000 sits 62.4% above the 2009 sale of £149,000. On a £-per-square-foot basis, the last sale (£283/sq ft) was about 30.5% above the typical sold price in the postcode. At 49 m² it sits well below the postcode median (95 m² across 14 EPCs), making it one of the more compact homes locally.
