4 Dark Lane, Sandon, Buntingford, SG9 0QT

4 Dark Lane is a four-bedroom semi-detached house in Sandon, Buntingford, Buntingford (SG9 0QT). It has a recorded floor area of 171 m² (around 1841 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (September 2014) shows a D (score 62), on the cusp of jumping into the C band. When first surveyed in February 2009 the rating was F, the property has climbed 2 bands since. Between certificates, roof efficiency went from Very Poor to Very Good, window efficiency went from Very Poor to Good and hot-water efficiency went from Very Poor to Poor; while wall efficiency dropped from Good to Very Poor. The recommended improvements would push it to C (score 73). Main heating runs on electricity. The latest certificate is from September 2014, so improvements made since then won't be reflected. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal.

It hasn't traded since June 2009, a hold of 17 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 171 m² the property is well over the postcode median (78 m² across 13 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £587,000 sits 134.8% above the 2009 sale of £249,995. On a £-per-square-foot basis, the last sale (£136/sq ft) was about 46.6% below the postcode norm. One historical planning record sits against the property in 2009.
