340 BATH ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 340 BATH ROAD sales from April 1998 and May 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 April 1998 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the May 2004 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 340 BATH ROAD be worth now?
