14 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 14 ROCKLIFFE AVENUE sales from February 2012 and April 2017 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 February 2012 sale was for 46% below the HPI. So the extrapolation line tracks at 46% below the HPI over time, until the April 2017 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 14 ROCKLIFFE AVENUE be worth now?

This is based on house price inflation of 18.7%, between April 2017 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 18.7% inflationary increase is applied to the most recent sale price for 14 ROCKLIFFE AVENUE of £800,000 on 20th April 2017. For the value to have increased from £800,000 to £949,541 over the eight years and two months to February 2025, the following assumptions must hold true:

• The value of 14 ROCKLIFFE AVENUE has moved in line with the HPI for detached houses in the Dacorum local authority area.
• The April 2017 sale price of £800,000 represented a fair market value for the property.
