About 15 St Johns Street
15 St Johns Street is a two-bedroom mid-terrace house in Aylesbury (HP20 1BS). It has a recorded floor area of 72 m² (around 775 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (January 2021) shows a C (score 69), just inside the C band. When first surveyed in October 2020 the rating was D, the property has climbed 1 band since. Between certificates, roof efficiency went from Very Poor to Average, window efficiency went from Average to Good and lighting went from Poor to Very Good. The recommended improvements would push it to B (score 90).
It hasn't traded since September 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 1997–2009, sale prices on this property compounded at 13.5% per year. Today's modelled estimate of £271,000 sits 83.7% above the 2009 sale of £147,500.
