188 HERLWYN AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 188 HERLWYN AVENUE sales from August 2015 and July 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 August 2015 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the July 2019 sale, where it rises to 40% above the HPI. The line then continues to track at 40% above the HPI.
