78 LLYS ONNEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Conwy local authority area over time, sourced from the HPI. The two 78 LLYS ONNEN sales from July 2010 and October 2016 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 July 2010 sale was for 29% above the HPI. So the extrapolation line tracks at 29% above the HPI over time, until the October 2016 sale, which was also at 29% above the HPI.
