11 COPPER BOX CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Test Valley local authority area over time, sourced from the HPI. The two 11 COPPER BOX CLOSE sales from December 2017 and July 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 2017 sale was for 45% below the HPI. So the extrapolation line tracks at 45% below the HPI over time, until the July 2025 sale, where it rises to 44% below the HPI. The line then continues to track at 44% below the HPI.
