8 CASTLE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Oxfordshire local authority area over time, sourced from the HPI. The two 8 CASTLE CLOSE sales from July 1995 and December 2016 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 1995 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the December 2016 sale, where it falls to 43% below the HPI. The line then continues to track at 43% below the HPI.

What might 8 CASTLE CLOSE be worth now?

8 CASTLE CLOSE might now be worth an estimated £453,455.

This is based on house price inflation of 26%, between December 2016 and February 2025, for detached houses, in the South Oxfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 26% inflationary increase is applied to the most recent sale price for 8 CASTLE CLOSE of £359,950 on 9th December 2016. For the value to have increased from £359,950 to £453,455 over the nine years and ten months to February 2025, the following assumptions must hold true:

• The value of 8 CASTLE CLOSE has moved in line with the HPI for detached houses in the South Oxfordshire local authority area.
• The December 2016 sale price of £359,950 represented a fair market value for the property.
• The size, condition, and specification of 8 CASTLE CLOSE has not materially changed since December 2016.
