21 KINSBOURNE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 21 KINSBOURNE CLOSE sales from October 2017 and March 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 October 2017 sale was for 47% below the HPI. So the extrapolation line tracks at 47% below the HPI over time, until the March 2021 sale, where it rises to 19% below the HPI.
