20 ROCKCHASE GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Havering local authority area over time, sourced from the HPI. The four 20 ROCKCHASE GARDENS sales between November 1998 and July 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 August 2001 sale was for 147% above the HPI. So the extrapolation line tracks at 147% above the HPI over time, until the July 2023 sale, where it falls to 111% above the HPI.

What might 20 ROCKCHASE GARDENS be worth now?
