Overview

About 12 Chartley Close

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

12 Chartley Close is a three-bedroom end-of-terrace house in St. Mellons, Cardiff, Cardiff (CF3 0SD). It has a recorded floor area of 63 m² (around 678 sq ft), construction records dating it to 1991-1995 and council tax band C. The latest certificate (August 2016) shows a C (score 69), just inside the C band. The recommended improvements would push it to B (score 84). The latest certificate is from August 2016, so improvements made since then won't be reflected.

Held since May 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. Across 1999–2007, sale prices on this property compounded at 17.1% per year. Today's modelled estimate of £255,000 is 41.7% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£265/sq ft) was about 61.4% above the typical sold price in the postcode.
