321 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 three 321 OLD SWANWICK LANE sales between August 1995 and April 2017 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 June 2002 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the April 2017 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.
