The below graph shows the average semi-detached house price in the Worthing local authority area over time, sourced from the HPI. The four 30 DOWNSIDE AVENUE sales between June 2001 and December 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 October 2011 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the December 2015 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.
30 DOWNSIDE AVENUE might now be worth an estimated £404,061.
This is based on house price inflation of 42.5%, between December 2015 and February 2025, 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 42.5% inflationary increase is applied to the most recent sale price for 30 DOWNSIDE AVENUE of £283,500 on 18th December 2015. For the value to have increased from £283,500 to £404,061 over the ten years and ten months to February 2025, the following assumptions must hold true:
