The below graph shows the average detached house price in the Sunderland local authority area over time, sourced from the HPI. The three 13 GRASSLEES sales between March 2002 and July 2026 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 October 2020 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the July 2026 sale, where it falls to 33% above the HPI. The line then continues to track at 33% above the HPI.
