15 WILLIAMS WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hertsmere local authority area over time, sourced from the HPI. The three 15 WILLIAMS WAY sales between September 2004 and May 2018 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 2006 sale was for 114% above the HPI. So the extrapolation line tracks at 114% above the HPI over time, until the May 2018 sale, where it falls to 61% above the HPI. The line then continues to track at 61% above the HPI.
