25 HAM ISLAND Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 25 HAM ISLAND sales from March 2012 and October 2019 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 March 2012 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the October 2019 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.
