17 COUSINS GROVE 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 four 17 COUSINS GROVE sales between November 2011 and July 2024 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 August 2018 sale was for 102% above the HPI. So the extrapolation line tracks at 102% above the HPI over time, until the July 2024 sale, where it rises to 145% above the HPI.
