20 NEWTON 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 20 NEWTON CLOSE sales from September 1996 and June 2023 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 1996 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the June 2023 sale, where it rises to 28% below the HPI. The line then continues to track at 28% below the HPI.
