7 KEYMER CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bromley local authority area over time, sourced from the HPI. The two 7 KEYMER CLOSE sales from September 1996 and May 2002 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 1996 sale was for 49% below the HPI. So the extrapolation line tracks at 49% below the HPI over time, until the May 2002 sale, where it rises to 47% below the HPI. The line then continues to track at 47% below the HPI.
