5 HAMMONDS HILL 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 5 HAMMONDS HILL sales from July 2000 and October 2004 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 2000 sale was for 149% above the HPI. So the extrapolation line tracks at 149% above the HPI over time, until the October 2004 sale, where it falls to 103% above the HPI. The line then continues to track at 103% above the HPI.

What might 5 HAMMONDS HILL be worth now?

5 HAMMONDS HILL might now be worth an estimated £2,524,195.

This is based on house price inflation of 131.6%, between October 2004 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 131.6% inflationary increase is applied to the most recent sale price for 5 HAMMONDS HILL of £1,090,000 on 11th October 2004. For the value to have increased from £1,090,000 to £2,524,195 over the nineteen years and ten months to December 2024, the following assumptions must hold true:

• The value of 5 HAMMONDS HILL has moved in line with the HPI for detached houses in the St Albans local authority area.
• The October 2004 sale price of £1,090,000 represented a fair market value for the property.
