44 DERWENT ROAD 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 44 DERWENT ROAD sales from February 1997 and January 2015 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 1997 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the January 2015 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 44 DERWENT ROAD be worth now?

44 DERWENT ROAD might now be worth an estimated £928,971.

This is based on house price inflation of 40.8%, between January 2015 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 40.8% inflationary increase is applied to the most recent sale price for 44 DERWENT ROAD of £660,000 on 23rd January 2015. For the value to have increased from £660,000 to £928,971 over the nine years and eleven months to February 2025, the following assumptions must hold true:

• The value of 44 DERWENT ROAD has moved in line with the HPI for detached houses in the St Albans local authority area.
• The January 2015 sale price of £660,000 represented a fair market value for the property.
