285 LONGSTONE ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 285 LONGSTONE ROAD sales between September 2012 and December 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 December 2017 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the December 2025 sale, where it rises to 76% above the HPI. The line then continues to track at 76% above the HPI.
