4 SOUTHDOWN AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dorset local authority area over time, sourced from the HPI. The three 4 SOUTHDOWN AVENUE sales between November 2006 and May 2010 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 2009 sale was for 62% above the HPI. So the extrapolation line tracks at 62% above the HPI over time, until the May 2010 sale, where it falls to 49% above the HPI. The line then continues to track at 49% above the HPI.

What might 4 SOUTHDOWN AVENUE be worth now?
