33 RIDGE 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 three 33 RIDGE AVENUE sales between March 2004 and May 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 February 2010 sale was for 47% below the HPI. So the extrapolation line tracks at 47% below the HPI over time, until the May 2011 sale, where it rises to 1% below the HPI. The line then continues to track at 1% below the HPI.

What might 33 RIDGE AVENUE be worth now?

33 RIDGE AVENUE might now be worth an estimated £1,229,136.

This is based on house price inflation of 79.4%, between May 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 79.4% inflationary increase is applied to the most recent sale price for 33 RIDGE AVENUE of £685,000 on 9th May 2011. For the value to have increased from £685,000 to £1,229,136 over the fourteen years and three months to February 2025, the following assumptions must hold true:
