The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two 9 HERMAN STREET sales from October 2017 and March 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the October 2017 sale was for 55% below the HPI. So the extrapolation line tracks at 55% below the HPI over time, until the March 2025 sale, where it rises to 52% below the HPI. The line then continues to track at 52% below the HPI.

9 HERMAN STREET might now be worth an estimated £406,740.
