THE FOLLIES Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The three THE FOLLIES sales between November 2002 and July 2019 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 May 2006 sale was for 72% above the HPI. So the extrapolation line tracks at 72% above the HPI over time, until the July 2019 sale, where it falls to 36% above the HPI. The line then continues to track at 36% above the HPI.

What might THE FOLLIES be worth now?

THE FOLLIES might now be worth an estimated £1,289,048.

This is based on house price inflation of 17.2%, between July 2019 and December 2024, for detached houses, in the Sevenoaks local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 17.2% inflationary increase is applied to the most recent sale price for THE FOLLIES of £1,100,000 on 5th July 2019. For the value to have increased from £1,100,000 to £1,289,048 over the four years and seven months to December 2024, the following assumptions must hold true:

• The value of THE FOLLIES has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The July 2019 sale price of £1,100,000 represented a fair market value for the property.
• The size, condition, and specification of THE FOLLIES has not materially changed since July 2019.
