30 ALZEY GARDENS 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 30 ALZEY GARDENS sales from November 1996 and July 2019 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 1996 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the July 2019 sale, where it falls to 35% below the HPI. The line then continues to track at 35% below the HPI.

What might 30 ALZEY GARDENS be worth now?

30 ALZEY GARDENS might now be worth an estimated £812,726.

This is based on house price inflation of 23.1%, between July 2019 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 23.1% inflationary increase is applied to the most recent sale price for 30 ALZEY GARDENS of £660,000 on 16th July 2019. For the value to have increased from £660,000 to £812,726 over the four years and seven months to December 2024, the following assumptions must hold true:

• The value of 30 ALZEY GARDENS has moved in line with the HPI for detached houses in the St Albans local authority area.
• The July 2019 sale price of £660,000 represented a fair market value for the property.
