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. Today's modelled estimate of £159,000 sits 63.9% above the 2009 sale of £97,000. At 52 m² it sits well below the postcode median (79 m² across 55 EPCs), making it one of the more compact homes locally.
