27 ALLENBY ROAD 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 27 ALLENBY ROAD sales from February 1995 and November 2004 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 February 1995 sale was for 49% below the HPI. So the extrapolation line tracks at 49% below the HPI over time, until the November 2004 sale, where it rises to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might 27 ALLENBY ROAD be worth now?
