15 ROTHAMSTED 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 15 ROTHAMSTED AVENUE sales between June 1997 and July 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 October 2000 sale was for 178% above the HPI. So the extrapolation line tracks at 178% above the HPI over time, until the July 2022 sale, where it rises to 180% above the HPI. The line then continues to track at 180% above the HPI.
