The below graph shows the average detached house price in the Portsmouth local authority area over time, sourced from the HPI. The two 13 PENRHYN AVENUE sales from October 2009 and October 2011 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 October 2009 sale was for 51% above the HPI. So the extrapolation line tracks at 51% above the HPI over time, until the October 2011 sale, where it rises to 58% above the HPI. The line then continues to track at 58% above the HPI.
13 PENRHYN AVENUE might now be worth an estimated £817,819.
