12 Mentone Avenue is a five-bedroom detached house in Aspley Guise, Milton Keynes, Milton Keynes (MK17 8EQ). It has a recorded floor area of 201 m² (around 2162 sq ft) and construction records dating it to 1950-1966. The latest certificate (July 2009) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 66). The latest certificate is from July 2009, so improvements made since then won't be reflected. Other recorded features include a conservatory and a basement.
Untraded for 17 years, with the last transfer in September 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales.
