19 MOSTYN SQUARE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 19 MOSTYN SQUARE sales from June 2008 and May 2013 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 2008 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the May 2013 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.
