About 9 Black Cat Street
9 Black Cat Street is a detached house in Northampton (NN5 4EF). It has a recorded floor area of 87 m² (around 931 sq ft), construction records dating it to 2007 onwards and council tax band C. At 87 m² this is the 10th smallest of 21 units on EPC record in the building, where floor areas span 66–194 m². The building's EPC ratings span C to B, with this unit at the bottom. The latest certificate (November 2011) shows a C (score 78), near the top of the C band. Earlier certificates rated it B (January 2011); the latest reading is one band lower. Between certificates, wall efficiency went from Good to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The latest certificate is from November 2011, so improvements made since then won't be reflected.
Held since December 2007 — that's 18 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. Today's modelled estimate of £189,000 is 44.8% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£140/sq ft) was about 19.3% below the postcode norm. At 87 m² it's 22.1% smaller than the typical home in the postcode (111 m² median across 20 EPCs).
