4 CASTLE CLOSE 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 4 CASTLE CLOSE sales from July 2016 and November 2017 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 July 2016 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the November 2017 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.

What might 4 CASTLE CLOSE be worth now?

4 CASTLE CLOSE might now be worth an estimated £564,932.

This is based on house price inflation of 19.6%, between November 2017 and June 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 19.6% inflationary increase is applied to the most recent sale price for 4 CASTLE CLOSE of £472,500 on 2nd November 2017. For the value to have increased from £472,500 to £564,932 over the eight years and five months to June 2025, the following assumptions must hold true:

  • The value of 4 CASTLE CLOSE has moved in line with the HPI for detached houses in the Arun local authority area.
  • The November 2017 sale price of £472,500 represented a fair market value for the property.
  • The size, condition, and specification of 4 CASTLE CLOSE has not materially changed since November 2017.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
