4 BLACKWELL GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 4 BLACKWELL GARDENS sales from February 2018 and June 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 February 2018 sale was for 43% below the HPI. So the extrapolation line tracks at 43% below the HPI over time, until the June 2018 sale, where it rises to 42% below the HPI. The line then continues to track at 42% below the HPI.
