12 WESTWATER Price Paid vs. HPI Average

The below graph shows the average detached house price in the Castle Point local authority area over time, sourced from the HPI. The two 12 WESTWATER sales from September 1996 and August 2002 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 September 1996 sale was for 58% above the HPI. So the extrapolation line tracks at 58% above the HPI over time, until the August 2002 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.

What might 12 WESTWATER be worth now?

12 WESTWATER might now be worth an estimated £693,689.

This is based on house price inflation of 177.5%, between August 2002 and May 2026, for detached houses, in the Castle Point local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 177.5% inflationary increase is applied to the most recent sale price for 12 WESTWATER of £249,995 on 2nd August 2002. For the value to have increased from £249,995 to £693,689 over the 24 years and three months to May 2026, the following assumptions must hold true:

• The value of 12 WESTWATER has moved in line with the HPI for detached houses in the Castle Point local authority area.
• The August 2002 sale price of £249,995 represented a fair market value for the property.
