The below graph shows the average detached house price in the Powys local authority area over time, sourced from the HPI. The three 1 CAE CASTELL sales between May 1997 and August 2024 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 2013 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the August 2024 sale, where it falls to 2% below the HPI. The line then continues to track at 2% below the HPI.
1 CAE CASTELL might now be worth an estimated £307,852.
This is based on house price deflation of 0.7%, between August 2024 and December 2024, for detached houses, in the Powys local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 0.7% deflationary decrease is applied to the most recent sale price for 1 CAE CASTELL of £310,000 on 1st August 2024. For the value to have decreased from £310,000 to £307,852 over the eight months to December 2024, the following assumptions must hold true:
