19 WEST COMMON Price Paid vs. HPI Average

The below graph shows the average terraced house price in the St Albans local authority area over time, sourced from the HPI. The seven 19 WEST COMMON sales between August 1997 and September 2022 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 July 2019 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the September 2022 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 19 WEST COMMON be worth now?

19 WEST COMMON might now be worth an estimated £658,696.

This is based on house price deflation of 0.2%, between September 2022 and June 2025, for terraced 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 0.2% deflationary decrease is applied to the most recent sale price for 19 WEST COMMON of £660,000 on 21st September 2022. For the value to have decreased from £660,000 to £658,696 over the three years and three months to June 2025, the following assumptions must hold true:

• The value of 19 WEST COMMON has moved in line with the HPI for terraced houses in the St Albans local authority area.
• The September 2022 sale price of £660,000 represented a fair market value for the property.
