9B CASTLE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Havant local authority area over time, sourced from the HPI. The four 9B CASTLE AVENUE sales between February 2005 and August 2023 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 2007 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the August 2023 sale, where it rises to 65% above the HPI. The line then continues to track at 65% above the HPI.
