About 4 Mill Street
4 Mill Street is a detached house in Upton, Northampton, Northampton (NN5 4DH). It has a recorded floor area of 42 m² (around 452 sq ft) and council tax band C. The latest certificate (December 2008) returns a B (score 83), comfortably above the UK average. The rating has held steady at B across 2 certificates since October 2008.

Held since January 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales.
