About 18 Aspen Close
18 Aspen Close is a two-bedroom semi-detached house in St. Mellons, Cardiff, Cardiff (CF3 0BT). It has a recorded floor area of 70 m² (around 756 sq ft), construction records dating it to 1976-1982 and council tax band C. The latest certificate (October 2008) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 77). The latest certificate is from October 2008, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.
It hasn't traded since April 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. Across 1997–2009, sale prices on this property compounded at 7.5% per year. Today's modelled estimate of £195,000 sits 85.7% above the 2009 sale of £105,000.
