Held since March 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 61 m² the property is well over the postcode median (46 m² across 32 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £226,000 sits 115.2% above the 2007 sale of £105,000. On a £-per-square-foot basis, the last sale (£160/sq ft) was about 47.5% above the typical sold price in the postcode.
