91a is a four-bedroom mid-terrace house in Lambeth, London, London (SE21 8JL). It has a recorded floor area of 103 m² (around 1109 sq ft), construction records dating it to 1967-1975 and council tax band D. The latest certificate (February 2015) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from February 2015, so improvements made since then won't be reflected.
Untraded for 17 years, with the last transfer in July 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales.
