15 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 15 HAM ISLAND sales from July 2005 and August 2023 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 July 2005 sale was for 51% below the HPI. So the extrapolation line tracks at 51% below the HPI over time, until the August 2023 sale, where it rises to 49% below the HPI. The line then continues to track at 49% below the HPI.
