11 Grassholm Road, Stockton On Tees, TS20 1AY

11 Grassholm Road is a semi-detached house in Stockton On Tees (TS20 1AY). It has a recorded floor area of 90 m² (around 969 sq ft), construction records dating it to 1930-1949 and council tax band A. The latest certificate (January 2014) shows a D (score 65), on the cusp of jumping into the C band. When first surveyed in November 2013 the rating was E, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Poor to Good and main heating went from Poor to Good. The recommended improvements would lift it to B (score 84), a 2-band jump. The latest certificate is from January 2014, so improvements made since then won't be reflected.

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. Today's modelled estimate of £115,000 sits 113.4% above the 2007 sale of £53,900. On a £-per-square-foot basis, the last sale (£56/sq ft) was about 38.7% below the postcode norm. One planning record on file: an extension refused in 2007.
