The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 12 DARWIN CLOSE sales from May 1999 and October 2001 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 May 1999 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the October 2001 sale, where it falls to 40% below the HPI. The line then continues to track at 40% below the HPI.

12 DARWIN CLOSE might now be worth an estimated £730,828.
This is based on house price inflation of 199.5%, between October 2001 and May 2026, for detached houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
