11 BLACKLEY CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Watford local authority area over time, sourced from the HPI. The two 11 BLACKLEY CLOSE sales from February 2005 and June 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 February 2005 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the June 2021 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.
