About 9 Brown Close
9 Brown Close is a four-bedroom detached house in Northampton (NN5 4UJ). It has a recorded floor area of 107 m² (around 1152 sq ft), construction records dating it to 2003-2006 and council tax band D. The latest certificate (April 2024) shows a C (score 76), near the top of the C band. The rating has held steady at C across 2 certificates since June 2009. Between certificates, window efficiency dropped from Good to Average and hot-water efficiency dropped from Very Good to Good. The recommended improvements would push it to B (score 86).
It hasn't traded since October 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 2007–2009, sale prices on this property compounded at -13.9% per year. Today's modelled estimate of £316,000 sits 80.6% above the 2009 sale of £174,950. On a £-per-square-foot basis, the last sale (£152/sq ft) was about 21% below the postcode norm. At 107 m² it sits well below the postcode median (188 m² across 5 EPCs), making it one of the more compact homes locally.
