15 SLAVE HILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 15 SLAVE HILL sales between July 1997 and September 2021 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 August 2004 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the September 2021 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.
