1A THORNHILL AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southampton local authority area over time, sourced from the HPI. The three 1A THORNHILL AVENUE sales between November 1999 and November 2018 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 April 2007 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the November 2018 sale, where it falls to 24% below the HPI. The line then continues to track at 24% below the HPI.
