10 CARMARTHEN AVENUE 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 three 10 CARMARTHEN AVENUE sales between June 2006 and October 2018 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 November 2011 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the October 2018 sale, where it rises to 45% above the HPI.
