42 STEWART 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 three 42 STEWART ROAD sales between September 2001 and December 2010 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 2004 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the December 2010 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might 42 STEWART ROAD be worth now?

This is based on house price inflation of 79.9%, between December 2010 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 79.9% inflationary increase is applied to the most recent sale price for 42 STEWART ROAD of £991,500 on 14th December 2010. For the value to have increased from £991,500 to £1,783,453 over the fifteen years and ten months to February 2025, the following assumptions must hold true:
