STONEACRE 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 STONEACRE sales between February 1997 and March 2016 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 November 2005 sale was for 283% above the HPI. So the extrapolation line tracks at 283% above the HPI over time, until the March 2016 sale, where it falls to 180% above the HPI. The line then continues to track at 180% above the HPI.

What might STONEACRE be worth now?

STONEACRE might now be worth an estimated £2,646,619.

This is based on house price inflation of 20.3%, between March 2016 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 20.3% inflationary increase is applied to the most recent sale price for STONEACRE of £2,200,000 on 21st March 2016. For the value to have increased from £2,200,000 to £2,646,619 over the seven years and three months to December 2024, the following assumptions must hold true:

• The value of STONEACRE has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The March 2016 sale price of £2,200,000 represented a fair market value for the property.
• The size, condition, and specification of STONEACRE has not materially changed since March 2016.
