9 COWPER ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Worthing local authority area over time, sourced from the HPI. The two 9 COWPER ROAD sales from July 1998 and November 2015 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 July 1998 sale was for 78% above the HPI. So the extrapolation line tracks at 78% above the HPI over time, until the November 2015 sale, which was also at 78% above the HPI.

What might 9 COWPER ROAD be worth now?

This is based on house price inflation of 40%, between November 2015 and December 2024, for semi-detached houses, in the Worthing local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 40% inflationary increase is applied to the most recent sale price for 9 COWPER ROAD of £535,000 on 16th November 2015. For the value to have increased from £535,000 to £749,051 over the eight years and eleven months to December 2024, the following assumptions must hold true:

• The value of 9 COWPER ROAD has moved in line with the HPI for semi-detached houses in the Worthing local authority area.
• The November 2015 sale price of £535,000 represented a fair market value for the property.
