20 ST SWITHIN WAY 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 20 ST SWITHIN WAY sales from October 2003 and May 2021 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 October 2003 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the May 2021 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 20 ST SWITHIN WAY be worth now?
