12 BOWNESS AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Adur local authority area over time, sourced from the HPI. The two 12 BOWNESS AVENUE sales from October 2012 and December 2022 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 2012 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the December 2022 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.

What might 12 BOWNESS AVENUE be worth now?

This is based on house price deflation of 1.6%, between December 2022 and August 2025, for 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 1.6% deflationary decrease is applied to the most recent sale price for 12 BOWNESS AVENUE of £575,000 on 2nd December 2022. For the value to have decreased from £575,000 to £565,893 over the three years and four months to August 2025, the following assumptions must hold true:

• The December 2022 sale price of £575,000 represented a fair market value for the property.
