30 ROUGHDOWN 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 four 30 ROUGHDOWN AVENUE sales between March 1996 and April 2016 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 2006 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the April 2016 sale, where it rises to 27% below the HPI. The line then continues to track at 27% below the HPI.

What might 30 ROUGHDOWN AVENUE be worth now?

This is based on house price inflation of 26.1%, between April 2016 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 26.1% inflationary increase is applied to the most recent sale price for 30 ROUGHDOWN AVENUE of £532,000 on 14th April 2016. For the value to have increased from £532,000 to £671,104 over the nine years and two months to February 2025, the following assumptions must hold true:
