The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The three 7 OLD HARPENDEN ROAD sales between October 1998 and July 2020 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 2007 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the July 2020 sale, where it rises to 17% above the HPI. The line then continues to track at 17% above the HPI.

7 OLD HARPENDEN ROAD might now be worth an estimated £1,404,244.
