TRELYSTAN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Conwy local authority area over time, sourced from the HPI. The three TRELYSTAN sales between May 1999 and July 2009 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 2001 sale was for 131% above the HPI. So the extrapolation line tracks at 131% above the HPI over time, until the July 2009 sale, where it rises to 158% above the HPI. The line then continues to track at 158% above the HPI.
