The below graph shows the average detached house price in the Three Rivers local authority area over time, sourced from the HPI. The four 1 THE DUMBLETONS sales between May 2002 and June 2025 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 2007 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the June 2025 sale, where it falls to 38% below the HPI. The line then continues to track at 38% below the HPI.

1 THE DUMBLETONS might now be worth an estimated £730,695.
This is based on house price deflation of 2%, between June 2025 and April 2026, for detached houses, in the Three Rivers local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
