About 12 Bryn Y Mor Crescent
12 Bryn Y Mor Crescent is a five-bedroom end-of-terrace house in Swansea (SA1 4QT). It has a recorded floor area of 171 m² (around 1841 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (January 2016) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from January 2016, so improvements made since then won't be reflected.
It hasn't traded since December 1996, a hold of 29 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. Today's modelled estimate of £235,000 sits 526.7% above the 1996 sale of £37,500. On a £-per-square-foot basis, the last sale (£20/sq ft) was about 75.1% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs).
