9 ALTON ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wandsworth local authority area over time, sourced from the HPI. The two 9 ALTON ROAD sales from September 2010 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 September 2010 sale was for 54% below the HPI. So the extrapolation line tracks at 54% below the HPI over time, until the August 2023 sale, where it falls to 64% below the HPI. The line then continues to track at 64% below the HPI.
