31 Hastings Crescent, Old St Mellons, Cardiff, CF3 5DF

31 Hastings Crescent is a four-bedroom detached house in Old St. Mellons, Cardiff, Cardiff (CF3 5DF). It has a recorded floor area of 119 m² (around 1281 sq ft), construction records dating it to 1991-1995 and council tax band F. The latest certificate (November 2013) shows a D (score 61), on the cusp of jumping into the C band. Earlier certificates rated it C (June 2009); the latest reading is one band lower. Between certificates, hot-water efficiency dropped from Good to Average and lighting dropped from Very Good to Poor. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from November 2013, so improvements made since then won't be reflected.

It hasn't traded since December 2009, a hold of 16 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 £440,000 sits 60% above the 2009 sale of £275,000. On a £-per-square-foot basis, the last sale (£215/sq ft) was about 67.8% above the typical sold price in the postcode. At 119 m² it's 17.8% larger than the typical home in the postcode (101 m² median across 23 EPCs).
