18 SEFTON 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 18 SEFTON AVENUE sales from August 2010 and June 2019 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 August 2010 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the June 2019 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 18 SEFTON AVENUE be worth now?

This is based on house price inflation of 22.3%, between June 2019 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 22.3% inflationary increase is applied to the most recent sale price for 18 SEFTON AVENUE of £390,000 on 7th June 2019. For the value to have increased from £390,000 to £477,116 over the six years and four months to February 2025, the following assumptions must hold true:
