11 SLADE CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two 11 SLADE CLOSE sales from February 1996 and August 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 February 1996 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the August 2022 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might 11 SLADE CLOSE be worth now?

11 SLADE CLOSE might now be worth an estimated £351,884.

This is based on house price inflation of 5.2%, between August 2022 and April 2026, for semi-detached houses, in the Vale of Glamorgan local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 5.2% inflationary increase is applied to the most recent sale price for 11 SLADE CLOSE of £334,500 on 8th August 2022. For the value to have increased from £334,500 to £351,884 over the four years and four months to April 2026, the following assumptions must hold true:

  • The value of 11 SLADE CLOSE has moved in line with the HPI for semi-detached houses in the Vale of Glamorgan local authority area.
  • The August 2022 sale price of £334,500 represented a fair market value for the property.
  • The size, condition, and specification of 11 SLADE CLOSE has not materially changed since August 2022.
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.
