417 BLACKFEN ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bexley local authority area over time, sourced from the HPI. The three 417 BLACKFEN ROAD sales between May 1995 and December 2008 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 1999 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the December 2008 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.
