10 PIPERS AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the St Albans local authority area over time, sourced from the HPI. The three 10 PIPERS AVENUE sales between May 2001 and September 2013 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 March 2006 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the September 2013 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might 10 PIPERS AVENUE be worth now?

10 PIPERS AVENUE might now be worth an estimated £869,744.

This is based on house price inflation of 68.1%, between September 2013 and February 2025, for semi-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 68.1% inflationary increase is applied to the most recent sale price for 10 PIPERS AVENUE of £517,550 on 7th September 2013. For the value to have increased from £517,550 to £869,744 over the twelve years and seven months to February 2025, the following assumptions must hold true:

• The value of 10 PIPERS AVENUE has moved in line with the HPI for semi-detached houses in the St Albans local authority area.
• The September 2013 sale price of £517,550 represented a fair market value for the property.
