| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|

The below graph shows the average semi-detached house price in the Adur local authority area over time, sourced from the HPI. The three 15 HILLSIDE ROAD sales between May 2003 and October 2013 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 2007 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the October 2013 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.

15 HILLSIDE ROAD might now be worth an estimated £332,310.
This is based on house price inflation of 78.8%, between October 2013 and August 2025, for semi-detached houses, in the Adur local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 78.8% inflationary increase is applied to the most recent sale price for 15 HILLSIDE ROAD of £185,850 on 28th October 2013. For the value to have increased from £185,850 to £332,310 over the twelve years and two months to August 2025, the following assumptions must hold true:
