About 21 Blackoak Road
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21 Blackoak Road is a detached house in Cardiff (CF23 6QT). It has a recorded floor area of 213 m² (around 2293 sq ft), construction records dating it to 1950-1966 and council tax band G. The latest certificate (September 2013) shows a D (score 56), a step below the typical UK home. The recommended improvements would push it to C (score 75). The latest certificate is from September 2013, so improvements made since then won't be reflected.
It hasn't traded since July 1996, a hold of 30 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 213 m² the property is well over the postcode median (123 m² across 17 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £754,000 sits 498.4% above the 1996 sale of £126,000. On a £-per-square-foot basis, the last sale (£55/sq ft) was about 82.6% below the postcode norm.
