About 18 Allard Close
18 Allard Close is a four-bedroom detached house in Northampton (NN3 5LY). It has a recorded floor area of 133 m² (around 1433 sq ft), construction records dating it to 1983-1990 and council tax band E. The latest certificate (December 2011) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 71). The latest certificate is from December 2011, so improvements made since then won't be reflected.
It hasn't traded since June 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. At 133 m² the property is well over the postcode median (77 m² across 32 EPCs), placing it in the larger end of the local stock. Across 2000–2007, sale prices on this property compounded at 6.5% per year. Today's modelled estimate of £369,000 sits 97.3% above the 2007 sale of £187,000. On a £-per-square-foot basis, the last sale (£131/sq ft) was about 25.6% below the postcode norm.
