PARKSTONE 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 PARKSTONE sales between December 1995 and July 2018 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 July 2014 sale was for 33% below the HPI. So the extrapolation line tracks at 33% below the HPI over time, until the July 2018 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might PARKSTONE be worth now?

PARKSTONE might now be worth an estimated £823,012.

This is based on house price inflation of 21%, between July 2018 and February 2025, 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 21% inflationary increase is applied to the most recent sale price for PARKSTONE of £679,995 on 23rd July 2018. For the value to have increased from £679,995 to £823,012 over the seven years and five months to February 2025, the following assumptions must hold true:

• The value of PARKSTONE has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The July 2018 sale price of £679,995 represented a fair market value for the property.
• The size, condition, and specification of PARKSTONE has not materially changed since July 2018.
