2 Insula Cottages, Bishop Middleham, Ferryhill, DL17 9AY

2 Insula Cottages is a three-bedroom mid-terrace house in Bishop Middleham, Ferryhill, Ferryhill (DL17 9AY). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to 1930-1949 and council tax band A. The latest certificate (June 2015) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from June 2015, so improvements made since then won't be reflected.

It hasn't traded since May 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. Today's modelled estimate of £111,000 sits 58.6% above the 2007 sale of £70,000. On a £-per-square-foot basis, the last sale (£83/sq ft) was about 23.9% below the postcode norm.
