39 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 two 39 RIDGE AVENUE sales from January 2011 and September 2013 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 2011 sale was for 50% below the HPI. So the extrapolation line tracks at 50% below the HPI over time, until the September 2013 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 39 RIDGE AVENUE be worth now?

39 RIDGE AVENUE might now be worth an estimated £1,383,585.

This is based on house price inflation of 64.7%, between September 2013 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 64.7% inflationary increase is applied to the most recent sale price for 39 RIDGE AVENUE of £840,000 on 27th September 2013. For the value to have increased from £840,000 to £1,383,585 over the twelve years and seven months to February 2025, the following assumptions must hold true:
