20 KNAPP DRIVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Horsham local authority area over time, sourced from the HPI. The two 20 KNAPP DRIVE sales from September 2017 and January 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 September 2017 sale was for 58% above the HPI. So the extrapolation line tracks at 58% above the HPI over time, until the January 2021 sale, where it falls to 8% below the HPI.
