23 COMMON LANE 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 23 COMMON LANE sales from January 1995 and September 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 January 1995 sale was for 33% below the HPI. So the extrapolation line tracks at 33% below the HPI over time, until the September 2001 sale, where it rises to 30% below the HPI. The line then continues to track at 30% below the HPI.

What might 23 COMMON LANE be worth now?

23 COMMON LANE might now be worth an estimated £867,217.

This is based on house price inflation of 204.3%, between September 2001 and February 2025, 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 204.3% inflationary increase is applied to the most recent sale price for 23 COMMON LANE of £285,000 on 14th September 2001. For the value to have increased from £285,000 to £867,217 over the 24 years and seven months to February 2025, the following assumptions must hold true:

• The value of 23 COMMON LANE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The September 2001 sale price of £285,000 represented a fair market value for the property.
