About 51 Colne Avenue
51 Colne Avenue is a three-bedroom semi-detached house in Watford (WD19 4JF). It has a recorded floor area of 79 m² (around 850 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (November 2023) shows a D (score 62), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 86), a 2-band jump.

Held since April 2007 — that's 19 years off the open market, well above the local norm. 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 £467,000 sits 183% above the 2007 sale of £165,000. On a £-per-square-foot basis, the last sale (£194/sq ft) was about 26.6% below the postcode norm. One planning record on file: subdivision refused in 2009.
