329 OLD SWANWICK LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Fareham local authority area over time, sourced from the HPI. The two 329 OLD SWANWICK LANE sales from July 2017 and June 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 July 2017 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the June 2021 sale, where it rises to 13% below the HPI. The line then continues to track at 13% below the HPI.
