Held since December 2009 — that's 16 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. Across 1995–2009, sale prices on this property compounded at 9% per year. Today's modelled estimate of £246,000 sits 93.7% above the 2009 sale of £127,000. On a £-per-square-foot basis, the last sale (£288/sq ft) was about 30.4% above the typical sold price in the postcode. At 41 m² it sits well below the postcode median (69 m² across 21 EPCs), making it one of the more compact homes locally.
