31 ROCKLIFFE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dacorum local authority area over time, sourced from the HPI. The two 31 ROCKLIFFE AVENUE sales from March 1996 and January 2008 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 March 1996 sale was for 46% below the HPI. So the extrapolation line tracks at 46% below the HPI over time, until the January 2008 sale, where it rises to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might 31 ROCKLIFFE AVENUE be worth now?

This is based on house price inflation of 79.3%, between January 2008 and February 2025, for detached houses, in the Dacorum local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 79.3% inflationary increase is applied to the most recent sale price for 31 ROCKLIFFE AVENUE of £367,000 on 25th January 2008. For the value to have increased from £367,000 to £658,122 over the sixteen years and eleven months to February 2025, the following assumptions must hold true:
