17 COLLEN WEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The three 17 COLLEN WEN sales between May 2000 and June 2021 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 2017 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the June 2021 sale, where it rises to 39% above the HPI.
