12 WEST WAY 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 four 12 WEST WAY sales between May 1997 and February 2024 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 June 2018 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the February 2024 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.

What might 12 WEST WAY be worth now?

12 WEST WAY might now be worth an estimated £1,679,967.

This is based on house price inflation of 0.4%, between February 2024 and June 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 0.4% inflationary increase is applied to the most recent sale price for 12 WEST WAY of £1,673,500 on 27th February 2024. For the value to have increased from £1,673,500 to £1,679,967 over the eight months to June 2025, the following assumptions must hold true:

• The value of 12 WEST WAY has moved in line with the HPI for detached houses in the St Albans local authority area.
• The February 2024 sale price of £1,673,500 represented a fair market value for the property.
• The size, condition, and specification of 12 WEST WAY has not materially changed since February 2024.
