12 GRASMERE 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 three 12 GRASMERE AVENUE sales between February 1998 and November 2022 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 2005 sale was for 110% above the HPI. So the extrapolation line tracks at 110% above the HPI over time, until the November 2022 sale, where it falls to 61% above the HPI. The line then continues to track at 61% above the HPI.
