18 TARRANT DRIVE 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 three 18 TARRANT DRIVE sales between June 1998 and December 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 September 2018 sale was for 50% below the HPI. So the extrapolation line tracks at 50% below the HPI over time, until the December 2022 sale, where it rises to 42% below the HPI. The line then continues to track at 42% below the HPI.

What might 18 TARRANT DRIVE be worth now?

18 TARRANT DRIVE might now be worth an estimated £718,194.

This is based on house price inflation of 3.3%, between December 2022 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 3.3% inflationary increase is applied to the most recent sale price for 18 TARRANT DRIVE of £695,000 on 14th December 2022. For the value to have increased from £695,000 to £718,194 over the three years and ten months to February 2025, the following assumptions must hold true:

• The value of 18 TARRANT DRIVE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The December 2022 sale price of £695,000 represented a fair market value for the property.
