11 SALISBURY AVENUE 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 11 SALISBURY AVENUE sales from December 2006 and October 2024 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 December 2006 sale was for 353% above the HPI. So the extrapolation line tracks at 353% above the HPI over time, until the October 2024 sale, where it falls to 200% above the HPI. The line then continues to track at 200% above the HPI.
