13 Caernarvon Avenue, Burnley, BB12 6BE

13 Caernarvon Avenue is a three-bedroom semi-detached house in Burnley (BB12 6BE). It has a recorded floor area of 86 m² (around 926 sq ft), construction records dating it to 1950-1966 and council tax band B. The latest certificate (January 2014) shows an E (score 40), well below the UK norm with real room to improve. When first surveyed in March 2009 the rating was F, the property has climbed 1 band since. Between certificates, roof efficiency dropped from Very Good to Good and hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from January 2014, so improvements made since then won't be reflected.

It hasn't traded since July 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 £146,000 is 46% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£108/sq ft) was about 20.8% below the postcode norm.
