3 BYDOWN 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 two 3 BYDOWN sales from April 2000 and October 2003 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 April 2000 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the October 2003 sale, where it rises to 1% below the HPI. The line then continues to track at 1% below the HPI.

What might 3 BYDOWN be worth now?

3 BYDOWN might now be worth an estimated £582,277.

This is based on house price inflation of 104.3%, between October 2003 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 104.3% inflationary increase is applied to the most recent sale price for 3 BYDOWN of £285,000 on 27th October 2003. For the value to have increased from £285,000 to £582,277 over the twenty years and ten months to December 2024, the following assumptions must hold true:

• The value of 3 BYDOWN has moved in line with the HPI for detached houses in the Lewes local authority area.
• The October 2003 sale price of £285,000 represented a fair market value for the property.
• The size, condition, and specification of 3 BYDOWN has not materially changed since October 2003.
