109 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 109 TOPSTREET WAY sales from March 1995 and May 2005 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 March 1995 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the May 2005 sale, where it rises to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 109 TOPSTREET WAY be worth now?

109 TOPSTREET WAY might now be worth an estimated £1,600,716.

This is based on house price inflation of 142.5%, between May 2005 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 142.5% inflationary increase is applied to the most recent sale price for 109 TOPSTREET WAY of £660,000 on 23rd May 2005. For the value to have increased from £660,000 to £1,600,716 over the eighteen years and five months to December 2024, the following assumptions must hold true:
