11 GREEN MOUNT Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Devon local authority area over time, sourced from the HPI. The two 11 GREEN MOUNT sales from October 2017 and November 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 October 2017 sale was for 49% above the HPI. So the extrapolation line tracks at 49% above the HPI over time, until the November 2020 sale, where it rises to 68% above the HPI. The line then continues to track at 68% above the HPI.

What might 11 GREEN MOUNT be worth now?

11 GREEN MOUNT might now be worth an estimated £911,738.

This is based on house price inflation of 18.4%, between November 2020 and December 2024, for detached houses, in the East Devon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 18.4% inflationary increase is applied to the most recent sale price for 11 GREEN MOUNT of £770,000 on 27th November 2020. For the value to have increased from £770,000 to £911,738 over the three years and eleven months to December 2024, the following assumptions must hold true:

• The value of 11 GREEN MOUNT has moved in line with the HPI for detached houses in the East Devon local authority area.
• The November 2020 sale price of £770,000 represented a fair market value for the property.
