The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 9 ALZEY GARDENS sales from April 2005 and May 2015 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 April 2005 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the May 2015 sale, which was also at 20% below the HPI.
9 ALZEY GARDENS might now be worth an estimated £985,471.
This is based on house price inflation of 41.4%, between May 2015 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 41.4% inflationary increase is applied to the most recent sale price for 9 ALZEY GARDENS of £697,000 on 22nd May 2015. For the value to have increased from £697,000 to £985,471 over the ten years and three months to February 2025, the following assumptions must hold true:
