21 Avondale Avenue, Newcastle Upon Tyne, NE12 7HT

21 Avondale Avenue is a three-bedroom detached house in Newcastle Upon Tyne (NE12 7HT). It has a recorded floor area of 145 m² (around 1561 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (April 2013) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in November 2008 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Average to Good and lighting went from Very Poor to Poor; while window efficiency dropped from Average to Poor. The recommended improvements would push it to C (score 79). The latest certificate is from April 2013, so improvements made since then won't be reflected. Other recorded features include a self-contained annexe.

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. At 145 m² the property is well over the postcode median (98 m² across 13 EPCs), placing it in the larger end of the local stock. Across 2001–2009, sale prices on this property compounded at 7.3% per year. Today's modelled estimate of £354,000 sits 50.6% above the 2009 sale of £235,000.
