About 17 Gould Close
17 Gould Close is a three-bedroom detached house in Old St. Mellons, Cardiff, Cardiff (CF3 5BD). It has a recorded floor area of 92 m² (around 992 sq ft), construction records dating it to 1996-2002 and council tax band E. The latest certificate (October 2009) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 75). The latest certificate is from October 2009, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.
Held since March 1997 — that's 29 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £336,000 sits 304.8% above the 1997 sale of £82,995. On a £-per-square-foot basis, the last sale (£84/sq ft) was about 29.9% below the postcode norm.
