About 17 Colne Avenue
17 Colne Avenue is a three-bedroom semi-detached house in Watford (WD19 4JF). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (December 2019) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since March 2009. Between certificates, lighting went from Very Poor to Poor; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The recommended improvements would lift it to B (score 88), a 2-band jump.
Untraded for 19 years, with the last transfer in December 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £451,000 sits 114.8% above the 2007 sale of £210,000. On a £-per-square-foot basis, the last sale (£250/sq ft) was about 22.7% below the postcode norm. One historical planning record sits against the property in 2008.
