12 WESTCLIFF Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The two 12 WESTCLIFF sales from June 1999 and November 2010 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 June 1999 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the November 2010 sale, where it rises to 138% above the HPI. The line then continues to track at 138% above the HPI.

What might 12 WESTCLIFF be worth now?
