Flat 4, 21 St Marys Close, Stockport, SK1 4BT

Flat 4 is a two-bedroom detached house in Stockport (SK1 4BT). It has a recorded floor area of 51 m² (around 549 sq ft), construction records dating it to 1991-1995 and council tax band A. At 51 m² this is the smallest unit on EPC record across the building (51–55 m²). The latest certificate (May 2016) shows a C (score 78), near the top of the C band. The rating has held steady at C across 3 certificates since June 2011. Between certificates, lighting went from Poor to Very Good; while hot-water efficiency dropped from Good to Average. The latest certificate is from May 2016, so improvements made since then won't be reflected.

It hasn't traded since May 2008, a hold of 18 years that's notably long for the area. Across the public record there are 4 sales, relatively high churn for a single property. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 1998–2008, sale prices on this property compounded at 10% per year. Today's modelled estimate of £123,000 sits 105% above the 2008 sale of £60,000.
