Held since June 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 128 m² the property is well over the postcode median (90 m² across 16 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 1995–2009, sale prices on this property compounded at 10.4% per year. Today's modelled estimate of £339,000 sits 118.7% above the 2009 sale of £155,000.
