About 23 Austin Street
23 Austin Street is a two-bedroom mid-terrace house in Northampton (NN1 3EY). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (February 2016) shows a D (score 63), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since December 2014. Between certificates, roof efficiency went from Poor to Average and hot-water efficiency went from Average to Good; while lighting dropped from Very Good to Very Poor. The recommended improvements would lift it to B (score 87), a 2-band jump. The latest certificate is from February 2016, so improvements made since then won't be reflected.
Untraded for 18 years, with the last transfer in November 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2003–2008, sale prices on this property compounded at 3.7% per year. Today's modelled estimate of £177,000 sits 68.6% above the 2008 sale of £105,000.
