12 GAINSBOROUGH AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Worthing local authority area over time, sourced from the HPI. The two 12 GAINSBOROUGH AVENUE sales from July 2011 and March 2013 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 2011 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the March 2013 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.

What might 12 GAINSBOROUGH AVENUE be worth now?
