The below graph shows the average detached house price in the Cumberland local authority area over time, sourced from the HPI. The two 1 BLACKADDER CLOSE sales from December 2020 and October 2025 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 December 2020 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the October 2025 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.
