4 TOPSTREET 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 two 4 TOPSTREET WAY sales from February 2008 and July 2020 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 February 2008 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the July 2020 sale, where it falls to 42% above the HPI. The line then continues to track at 42% above the HPI.

What might 4 TOPSTREET WAY be worth now?

This is based on house price inflation of 21.2%, between July 2020 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 21.2% inflationary increase is applied to the most recent sale price for 4 TOPSTREET WAY of £1,455,000 on 10th July 2020. For the value to have increased from £1,455,000 to £1,763,271 over the three years and seven months to December 2024, the following assumptions must hold true:
