THE HAVEN 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 HAVEN sales between July 2000 and September 2006 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 December 2002 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the September 2006 sale, where it falls to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might THE HAVEN be worth now?

THE HAVEN might now be worth an estimated £1,028,518.

This is based on house price inflation of 94.1%, between September 2006 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 94.1% inflationary increase is applied to the most recent sale price for THE HAVEN of £530,000 on 4th September 2006. For the value to have increased from £530,000 to £1,028,518 over the seventeen years and nine months to December 2024, the following assumptions must hold true:

• The value of THE HAVEN has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The September 2006 sale price of £530,000 represented a fair market value for the property.
• The size, condition, and specification of THE HAVEN has not materially changed since September 2006.
