140 HERLWYN AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hillingdon local authority area over time, sourced from the HPI. The three 140 HERLWYN AVENUE sales between November 2009 and October 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 February 2018 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the October 2023 sale, where it falls to 43% below the HPI. The line then continues to track at 43% below the HPI.
