45 BILLY LOWS LANE 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 two 45 BILLY LOWS LANE sales from March 2014 and August 2021 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 March 2014 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the August 2021 sale, where it rises to 33% below the HPI. The line then continues to track at 33% below the HPI.
