17 Castledale Grove is a two-bedroom semi-detached house in Sheffield (S2 1NJ). It has a recorded floor area of 56 m² (around 603 sq ft), construction records dating it to 1991-1995 and council tax band A. The latest certificate (July 2019) shows a D (score 64), on the cusp of jumping into the C band. Earlier certificates rated it C (October 2009); the latest reading is one band lower. Between certificates, lighting went from Very Poor to Very Good. The recommended improvements would lift it to B (score 87), a 2-band jump.
It hasn't traded since October 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Sale prices here have outpaced Sheffield HPI: 5.6% per year against 0% for the wider region. Today's modelled estimate of £136,000 sits 109.2% above the 2009 sale of £65,000. On a £-per-square-foot basis, the last sale (£108/sq ft) was about 54.9% above the typical sold price in the postcode. At 56 m² it's 18.8% smaller than the typical home in the postcode (69 m² median across 35 EPCs).
