21 Mayfield Gardens, Halifax, HX1 3XF

21 Mayfield Gardens is a three-bedroom mid-terrace house in Halifax (HX1 3XF). It has a recorded floor area of 107 m² (around 1152 sq ft), construction records dating it to 1930-1949 and council tax band A. The latest certificate (May 2015) shows a D (score 63), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since June 2014. Between certificates, wall efficiency dropped from Good to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 79). The latest certificate is from May 2015, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.

Untraded for 19 years, with the last transfer in October 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 107 m² the property is well over the postcode median (59 m² across 19 EPCs), placing it in the larger end of the local stock. One planning record on file: an extension approved in 2005. Past consents include an extension, meaningful when judging how the property has evolved. Across 1997–2007, sale prices on this property compounded at 12.1% per year. Today's modelled estimate of £123,000 is 27.5% above the 2007 sale price.
