447 LUTON 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 447 LUTON ROAD sales from November 2005 and November 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 November 2005 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the November 2015 sale, where it falls to 13% below the HPI. The line then continues to track at 13% below the HPI.

What might 447 LUTON ROAD be worth now?

This is based on house price inflation of 25.4%, between November 2015 and March 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 25.4% inflationary increase is applied to the most recent sale price for 447 LUTON ROAD of £830,000 on 26th November 2015. For the value to have increased from £830,000 to £1,040,436 over the ten years and eight months to March 2025, the following assumptions must hold true:

• The November 2015 sale price of £830,000 represented a fair market value for the property.
