1 KEMPS PIECE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two 1 KEMPS PIECE sales from November 1995 and November 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 November 1995 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the November 2018 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 1 KEMPS PIECE be worth now?

1 KEMPS PIECE might now be worth an estimated £774,855.

This is based on house price inflation of 10.7%, between November 2018 and December 2024, for detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 10.7% inflationary increase is applied to the most recent sale price for 1 KEMPS PIECE of £700,000 on 28th November 2018. For the value to have increased from £700,000 to £774,855 over the five years and eleven months to December 2024, the following assumptions must hold true:

• The value of 1 KEMPS PIECE has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The November 2018 sale price of £700,000 represented a fair market value for the property.
• The size, condition, and specification of 1 KEMPS PIECE has not materially changed since November 2018.
