41 MOSTYN SQUARE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The two 41 MOSTYN SQUARE sales from May 2009 and January 2016 have been plotted on the graph.

For example, the May 2009 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the January 2016 sale, where it rises to 43% above the HPI. The line then continues to track at 43% above the HPI.
