22 PROSPECT 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 22 PROSPECT LANE sales from November 2010 and May 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 November 2010 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the May 2012 sale, where it rises to 179% above the HPI. The line then continues to track at 179% above the HPI.

What might 22 PROSPECT LANE be worth now?

This is based on house price inflation of 72.6%, between May 2012 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 72.6% inflationary increase is applied to the most recent sale price for 22 PROSPECT LANE of £1,999,999 on 18th May 2012. For the value to have increased from £1,999,999 to £3,451,525 over the thirteen years and three months to February 2025, the following assumptions must hold true:

• The value of 22 PROSPECT LANE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The May 2012 sale price of £1,999,999 represented a fair market value for the property.
