128 MARSHALL SQUARE 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 two 128 MARSHALL SQUARE sales from August 2003 and September 2014 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 August 2003 sale was for 93% above the HPI. So the extrapolation line tracks at 93% above the HPI over time, until the September 2014 sale, where it falls to 75% above the HPI. The line then continues to track at 75% above the HPI.
