5 SOUTHDOWN ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Arun local authority area over time, sourced from the HPI. The three 5 SOUTHDOWN ROAD sales between September 1999 and February 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 February 2001 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the February 2015 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 5 SOUTHDOWN ROAD be worth now?

5 SOUTHDOWN ROAD might now be worth an estimated £506,508.

This is based on house price inflation of 49%, between February 2015 and February 2025, for detached houses, in the Arun local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 49% inflationary increase is applied to the most recent sale price for 5 SOUTHDOWN ROAD of £340,000 on 20th February 2015. For the value to have increased from £340,000 to £506,508 over the ten years to February 2025, the following assumptions must hold true:

• The value of 5 SOUTHDOWN ROAD has moved in line with the HPI for detached houses in the Arun local authority area.
• The February 2015 sale price of £340,000 represented a fair market value for the property.
• The size, condition, and specification of 5 SOUTHDOWN ROAD has not materially changed since February 2015.
