GAIRLOCH Price Paid vs. HPI Average

The below graph shows the average detached house price in the Winchester local authority area over time, sourced from the HPI. The two GAIRLOCH sales from July 2002 and March 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 July 2002 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the March 2025 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.
