KNAPTON 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 two KNAPTON sales from August 2000 and August 2015 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 August 2000 sale was for 310% above the HPI. So the extrapolation line tracks at 310% above the HPI over time, until the August 2015 sale, where it falls to 240% above the HPI. The line then continues to track at 240% above the HPI.

What might KNAPTON be worth now?

KNAPTON might now be worth an estimated £3,211,544.

This is based on house price inflation of 31.1%, between August 2015 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 31.1% inflationary increase is applied to the most recent sale price for KNAPTON of £2,450,000 on 6th August 2015. For the value to have increased from £2,450,000 to £3,211,544 over the eight years and eight months to December 2024, the following assumptions must hold true:

• The value of KNAPTON has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The August 2015 sale price of £2,450,000 represented a fair market value for the property.
• The size, condition, and specification of KNAPTON has not materially changed since August 2015.
