18 HILLSIDE AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Southampton local authority area over time, sourced from the HPI. The two 18 HILLSIDE AVENUE sales from September 1997 and September 2011 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 September 1997 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the September 2011 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might 18 HILLSIDE AVENUE be worth now?
