1 THE DUMBLETONS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Three Rivers local authority area over time, sourced from the HPI. The three 1 THE DUMBLETONS sales between May 2002 and October 2007 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 2003 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the October 2007 sale, where it rises to 26% below the HPI. The line then continues to track at 26% below the HPI.

What might 1 THE DUMBLETONS be worth now?

This is based on house price inflation of 67.1%, between October 2007 and February 2025, 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).

The 67.1% inflationary increase is applied to the most recent sale price for 1 THE DUMBLETONS of £499,950 on 18th October 2007. For the value to have increased from £499,950 to £835,555 over the eighteen years and eight months to February 2025, the following assumptions must hold true:
