Held since May 1996 — that's 30 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £131,000 sits 223.5% above the 1996 sale of £40,500. On a £-per-square-foot basis, the last sale (£111/sq ft) was about 35.9% below the postcode norm.
