About Mavis Bank
Mavis Bank is a detached house in Daventry (NN11 4HJ). It has a recorded floor area of 106 m² (around 1137 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (April 2009) shows an E (score 49), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 66).

Untraded for 17 years, with the last transfer in November 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales.
