21 THE KNOLE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gravesham local authority area over time, sourced from the HPI. The three 21 THE KNOLE sales between March 1996 and December 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 June 2007 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the December 2019 sale, where it rises to 21% below the HPI. The line then continues to track at 21% below the HPI.

What might 21 THE KNOLE be worth now?

21 THE KNOLE might now be worth an estimated £498,284.

This is based on house price inflation of 18.6%, between December 2019 and February 2025, for detached houses, in the Gravesham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 18.6% inflationary increase is applied to the most recent sale price for 21 THE KNOLE of £420,000 on 6th December 2019. For the value to have increased from £420,000 to £498,284 over the six years and ten months to February 2025, the following assumptions must hold true:

• The value of 21 THE KNOLE has moved in line with the HPI for detached houses in the Gravesham local authority area.
• The December 2019 sale price of £420,000 represented a fair market value for the property.
• The size, condition, and specification of 21 THE KNOLE has not materially changed since December 2019.
