20 WESTLANDS AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Slough local authority area over time, sourced from the HPI. The two 20 WESTLANDS AVENUE sales from May 2005 and May 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 May 2005 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the May 2013 sale, where it rises to 25% above the HPI. The line then continues to track at 25% above the HPI.
