27 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 27 MOSTYN SQUARE sales from March 2009 and April 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 March 2009 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the April 2010 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.
