About 9 Byron Street
9 Byron Street is a mid-terrace house in Northampton (NN2 7JE). It has a recorded floor area of 81 m² (around 872 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (March 2016) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected.
It hasn't traded since January 1999, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £200,000 sits 433.3% above the 1999 sale of £37,500. On a £-per-square-foot basis, the last sale (£43/sq ft) was about 69.7% below the postcode norm.
