20 Castlefields Avenue, Charlton Kings, Cheltenham, GL52 6YR

20 Castlefields Avenue is a three-bedroom semi-detached house in Charlton Kings, Cheltenham, Cheltenham (GL52 6YR). It has a recorded floor area of 84 m² (around 904 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (February 2015) shows a C (score 76), near the top of the C band. The recommended improvements would push it to B (score 87). The latest certificate is from February 2015, so improvements made since then won't be reflected.

It hasn't traded since June 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2001–2007, sale prices on this property compounded at 14.5% per year. Today's modelled estimate of £375,000 sits 64.1% above the 2007 sale of £228,500. On a £-per-square-foot basis, the last sale (£253/sq ft) was about 17.4% above the typical sold price in the postcode. One planning record on file: an extension approved in 2012. Past consents include an extension, meaningful when judging how the property has evolved.
