28 RIVERDALE Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Devon local authority area over time, sourced from the HPI. The two 28 RIVERDALE sales from September 2007 and March 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 September 2007 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the March 2026 sale, where it falls to 40% below the HPI. The line then continues to track at 40% below the HPI.

What might 28 RIVERDALE be worth now?
