Held since June 2008 — that's 18 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 76 m² it sits well below the postcode median (122 m² across 13 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 77% of similar EPCs). Across 2005–2008, sale prices on this property compounded at 3.9% per year. Today's modelled estimate of £200,000 is 37.9% above the 2008 sale price.
