About 17 Eaton Avenue
17 Eaton Avenue is a semi-detached house in High Wycombe (HP12 3BP). It has a recorded floor area of 86 m² (around 926 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (March 2014) shows a D (score 58), a step below the typical UK home. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from March 2014, so improvements made since then won't be reflected.
Held since June 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.
