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. Across 1996–2007, sale prices on this property compounded at 14% per year. Today's modelled estimate of £235,000 sits 51.6% above the 2007 sale of £155,000. On a £-per-square-foot basis, the last sale (£576/sq ft) was about 68.6% above the typical sold price in the postcode. At 25 m² it sits well below the postcode median (66 m² across 18 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 72% of similar EPCs).
