15 ISLAY GARDENS 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 15 ISLAY GARDENS sales between July 2004 and September 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 2014 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the September 2024 sale, where it falls to 14% above the HPI. The line then continues to track at 14% above the HPI.
