21 HILLSIDE WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Brighton and Hove local authority area over time, sourced from the HPI. The three 21 HILLSIDE WAY sales between April 1996 and November 2006 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 October 2002 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the November 2006 sale, where it rises to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 21 HILLSIDE WAY be worth now?
