20 HAROLD ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Southampton local authority area over time, sourced from the HPI. The three 20 HAROLD ROAD sales between December 2011 and January 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 January 2021 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the January 2024 sale, where it rises to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 20 HAROLD ROAD be worth now?
