Held since May 1999 — that's 27 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 £185,000 sits 302.2% above the 1999 sale of £46,000. On a £-per-square-foot basis, the last sale (£102/sq ft) was about 45.5% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs).
