It hasn't traded since February 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 220 m² the property is well over the postcode median (114 m² across 8 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £517,000 is 38.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£158/sq ft) was about 31.3% above the typical sold price in the postcode.
Walnut House's carbon output runs well above what efficient homes in the postcode produce.
