12 Calder Avenue, Nether Poppleton, York, YO26 6RG

12 Calder Avenue is a three-bedroom semi-detached house in Nether Poppleton, York, York (YO26 6RG). It has a recorded floor area of 76 m² (around 818 sq ft), construction records dating it to 1996-2002 and council tax band C. The latest certificate (February 2014) shows a D (score 66), on the cusp of jumping into the C band. When first surveyed in November 2013 the rating was E, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Average to Good; while lighting dropped from Very Good to Good. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from February 2014, so improvements made since then won't be reflected. Other recorded features include a conservatory.

Held since December 2004 — that's 22 years off the open market, well above the local norm. Across 1998–2004, sale prices on this property compounded at 11.6% per year.

Past consents include an extension, meaningful when judging how the property has evolved.
