20a, Windmill Road, Thame, OX9 2DR
About 20a
20a is a three-bedroom semi-detached house in Thame (OX9 2DR). It has a recorded floor area of 48 m² (around 517 sq ft), construction records dating it to 1996-2002 and council tax band D. The latest certificate (February 2012) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 70). The latest certificate is from February 2012, so improvements made since then won't be reflected.
Held since September 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. At 48 m² it sits well below the postcode median (84 m² across 23 EPCs), making it one of the more compact homes locally. Across 1998–2007, sale prices on this property compounded at 10.5% per year. Today's modelled estimate of £397,000 is 34.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£571/sq ft) was about 92.8% above the typical sold price in the postcode.
