77 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 77 CARMARTHEN AVENUE sales between June 2002 and November 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 January 2013 sale was for 100% above the HPI. So the extrapolation line tracks at 100% above the HPI over time, until the November 2018 sale, where it falls to 91% above the HPI.
