25 FIRST AVENUE 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 two 25 FIRST AVENUE sales from June 2007 and June 2014 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 June 2007 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the June 2014 sale, where it rises to 59% above the HPI. The line then continues to track at 59% above the HPI.

What might 25 FIRST AVENUE be worth now?

25 FIRST AVENUE might now be worth an estimated £929,745.

This is based on house price inflation of 61%, between June 2014 and August 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 61% inflationary increase is applied to the most recent sale price for 25 FIRST AVENUE of £577,500 on 3rd June 2014. For the value to have increased from £577,500 to £929,745 over the ten years and ten months to August 2025, the following assumptions must hold true:

• The value of 25 FIRST AVENUE has moved in line with the HPI for detached houses in the Arun local authority area.
• The June 2014 sale price of £577,500 represented a fair market value for the property.
• The size, condition, and specification of 25 FIRST AVENUE has not materially changed since June 2014.
