21 NORHAM AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southampton local authority area over time, sourced from the HPI. The five 21 NORHAM AVENUE sales between December 2001 and October 2020 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 June 2015 sale was for 34% below the HPI. So the extrapolation line tracks at 34% below the HPI over time, until the October 2020 sale, which was also at 34% below the HPI.

What might 21 NORHAM AVENUE be worth now?
