21 WEST COMMON Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 21 WEST COMMON sales from September 2001 and September 2012 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 2001 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the September 2012 sale, where it falls to 24% below the HPI. The line then continues to track at 24% below the HPI.

What might 21 WEST COMMON be worth now?

This is based on house price inflation of 72.1%, between September 2012 and December 2024, 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).

The 72.1% inflationary increase is applied to the most recent sale price for 21 WEST COMMON of £550,000 on 27th September 2012. For the value to have increased from £550,000 to £946,651 over the eleven years and nine months to December 2024, the following assumptions must hold true:
