20 DUCHESS DRIVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Lewes local authority area over time, sourced from the HPI. The three 20 DUCHESS DRIVE sales between May 1997 and April 2022 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 February 2011 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the April 2022 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might 20 DUCHESS DRIVE be worth now?

This is based on house price deflation of 4.3%, between April 2022 and December 2024, for detached houses, in the Lewes local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.3% deflationary decrease is applied to the most recent sale price for 20 DUCHESS DRIVE of £805,000 on 1st April 2022. For the value to have decreased from £805,000 to £770,502 over the one year and four months to December 2024, the following assumptions must hold true:
