About 9 Blaenrhondda Road
9 Blaenrhondda Road is a three-bedroom semi-detached house in Blaenrhondda, Treorchy, Treorchy (CF42 5SP). It has a recorded floor area of 89 m² (around 957 sq ft), construction records dating it to 1930-1949 and council tax band A. The latest certificate (November 2008) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 76). The latest certificate is from November 2008, so improvements made since then won't be reflected.
It hasn't traded since April 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. Today's modelled estimate of £123,000 sits 75.7% above the 2009 sale of £70,000.
