4 SIR JOSEPHS WALK Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the St Albans local authority area over time, sourced from the HPI. The two 4 SIR JOSEPHS WALK sales from April 1995 and August 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 April 1995 sale was for 75% above the HPI. So the extrapolation line tracks at 75% above the HPI over time, until the August 2023 sale, where it falls to 24% above the HPI. The line then continues to track at 24% above the HPI.
