About 23 St Marys Road

The recommended improvements would lift it to C (score 75), a 3-band jump. The latest certificate is from March 2015, so improvements made since then won't be reflected.
Untraded for 19 years, with the last transfer in November 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
