Held since December 2008 — that's 17 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. Today's modelled estimate of £280,000 sits 100% above the 2008 sale of £140,000. On a £-per-square-foot basis, the last sale (£203/sq ft) was about 30% below the postcode norm. Its energy rating outperforms most of the postcode (better than 75% of similar EPCs). 2 bedrooms is on the smaller side for this postcode, where 4 is the typical count.
