DOLPHIN HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Portsmouth local authority area over time, sourced from the HPI. The two DOLPHIN HOUSE sales from July 2013 and April 2016 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 July 2013 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the April 2016 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.
