15 MARQUIS LANE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the St Albans local authority area over time, sourced from the HPI. The four 15 MARQUIS LANE sales between July 1998 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 September 2015 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the September 2022 sale, where it falls to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might 15 MARQUIS LANE be worth now?

15 MARQUIS LANE might now be worth an estimated £855,853.

This is based on house price inflation of 1.9%, between September 2022 and February 2025, for semi-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 1.9% inflationary increase is applied to the most recent sale price for 15 MARQUIS LANE of £840,000 on 7th September 2022. For the value to have increased from £840,000 to £855,853 over the three years and seven months to February 2025, the following assumptions must hold true:

• The value of 15 MARQUIS LANE has moved in line with the HPI for semi-detached houses in the St Albans local authority area.
• The September 2022 sale price of £840,000 represented a fair market value for the property.
