Held since May 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. At 166 m² the property is well over the postcode median (57 m² across 8 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 75% of similar EPCs). Across 2002–2009, sale prices on this property compounded at -0.8% per year. Today's modelled estimate of £578,000 sits 106.4% above the 2009 sale of £280,000. On a £-per-square-foot basis, the last sale (£157/sq ft) was about 37% below the postcode norm.
