That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.

Its energy rating outperforms most of the postcode (better than 87% of similar EPCs). 5 planning records sit against the property, 5 approved, 0 refused. Past consents include a loft conversion, meaningful when judging how the property has evolved. Today's modelled estimate of £302,000 is 20.8% above the 2008 sale price.
