Get started18 Newnham Green is a three-bedroom detached house in Crowmarsh Gifford, Wallingford, Wallingford (OX10 8EW). It has a recorded floor area of 51 m² (around 554 sq ft), construction records dating it to 1976-1982 and council tax band D. The latest certificate (March 2012) shows a D (score 65), on the cusp of jumping into the C band. The latest certificate is from March 2012, so improvements made since then won't be reflected.
It hasn't traded since July 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Sale prices here have outpaced England HPI: 6.6% per year against 0% for the wider region. Today's modelled estimate of £458,000 sits 69.7% above the 2007 sale of £269,950. On a £-per-square-foot basis, the last sale (£487/sq ft) was about 88.3% above the typical sold price in the postcode. At 51 m² it sits well below the postcode median (84 m² across 27 EPCs), making it one of the more compact homes locally. One historical planning record sits against the property in 2013.
18 Newnham Green's EPC is over a decade old — improvements since won't be reflected.
