24 ROTHAMSTED AVENUE 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 24 ROTHAMSTED AVENUE sales from November 1995 and January 2008 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 1995 sale was for 101% above the HPI. So the extrapolation line tracks at 101% above the HPI over time, until the January 2008 sale, where it rises to 113% above the HPI. The line then continues to track at 113% above the HPI.

What might 24 ROTHAMSTED AVENUE be worth now?

24 ROTHAMSTED AVENUE might now be worth an estimated £2,652,624.

This is based on house price inflation of 85.8%, between January 2008 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 85.8% inflationary increase is applied to the most recent sale price for 24 ROTHAMSTED AVENUE of £1,427,800 on 29th January 2008. For the value to have increased from £1,427,800 to £2,652,624 over the fifteen years and one month to December 2024, the following assumptions must hold true:

• The value of 24 ROTHAMSTED AVENUE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The January 2008 sale price of £1,427,800 represented a fair market value for the property.
