THE GROVE 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 THE GROVE sales from June 2004 and October 2021 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 June 2004 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the October 2021 sale, where it falls to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might THE GROVE be worth now?

THE GROVE might now be worth an estimated £1,063,673.

This is based on house price inflation of 9.7%, between October 2021 and December 2024, for detached houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 9.7% inflationary increase is applied to the most recent sale price for THE GROVE of £970,000 on 11th October 2021. For the value to have increased from £970,000 to £1,063,673 over the two years and ten months to December 2024, the following assumptions must hold true:

• The value of THE GROVE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The October 2021 sale price of £970,000 represented a fair market value for the property.
• The size, condition, and specification of THE GROVE has not materially changed since October 2021.
