41 CLAYGATE 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 41 CLAYGATE AVENUE sales from September 1999 and October 2011 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 1999 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the October 2011 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 41 CLAYGATE AVENUE be worth now?

This is based on house price inflation of 75.3%, between October 2011 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 75.3% inflationary increase is applied to the most recent sale price for 41 CLAYGATE AVENUE of £970,000 on 20th October 2011. For the value to have increased from £970,000 to £1,700,071 over the fourteen years and eight months to February 2025, the following assumptions must hold true:
