The below graph shows the average terraced house price in the Dacorum local authority area over time, sourced from the HPI. The two 1 CAERNARVON CLOSE sales from January 2012 and August 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 January 2012 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the August 2017 sale, which was also at 35% above the HPI.

1 CAERNARVON CLOSE might now be worth an estimated £576,682.
This is based on house price inflation of 22.7%, between August 2017 and October 2025, for terraced 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 22.7% inflationary increase is applied to the most recent sale price for 1 CAERNARVON CLOSE of £470,000 on 29th August 2017. For the value to have increased from £470,000 to £576,682 over the seven years and ten months to October 2025, the following assumptions must hold true:
