About 21 Stallcourt Avenue
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21 Stallcourt Avenue is a three-bedroom mid-terrace house in Cardiff (CF23 5AL). It has a recorded floor area of 129 m² (around 1389 sq ft), construction records dating it to 1900-1929 and council tax band F. The latest certificate (August 2016) shows a C (score 71). The recommended improvements would push it to B (score 84). The latest certificate is from August 2016, so improvements made since then won't be reflected.
It hasn't traded since July 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 £478,000 sits 99.2% above the 2007 sale of £239,950. On a £-per-square-foot basis, the last sale (£173/sq ft) was about 25.1% below the postcode norm. One planning record on file: an extension approved in 2008. Past consents include an extension, meaningful when judging how the property has evolved. At 129 m² it's 17.8% larger than the typical home in the postcode (109 m² median across 15 EPCs). Its energy rating outperforms most of the postcode (better than 87% of similar EPCs).
