1 REDBOURN LANE 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 1 REDBOURN LANE sales between August 1999 and July 2011 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 2002 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the July 2011 sale, which was also at 28% above the HPI.

What might 1 REDBOURN LANE be worth now?

1 REDBOURN LANE might now be worth an estimated £1,596,704.

This is based on house price inflation of 80.2%, between July 2011 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 80.2% inflationary increase is applied to the most recent sale price for 1 REDBOURN LANE of £886,000 on 29th July 2011. For the value to have increased from £886,000 to £1,596,704 over the twelve years and seven months to December 2024, the following assumptions must hold true:

• The value of 1 REDBOURN LANE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The July 2011 sale price of £886,000 represented a fair market value for the property.
